Overhead and Profit (O&P) on a Roofing Insurance Estimate: What It Is and When It Belongs

Two estimates cross an adjuster's desk for the same hail-damaged roof. Same shingle, same squares, same code items, same defensible unit prices. One estimate totals $13,800. The other totals $16,560. The only difference is two line items at the bottom of the second one: 10% overhead and 10% profit, layered on top of the trade work.

The roofer who wrote the $16,560 estimate isn't padding. He's a general contractor coordinating multiple trades on a job complex enough that, by the carrier's own internal guidelines, overhead and profit is owed. The roofer who left it off either didn't know it applied, didn't document why it applied, or got told "we don't pay O&P" and folded. That $2,760 gap is real money, and on the wrong side of it sits a contractor eating his own coordination costs.

If you write estimates on storm work, overhead and profit, the line everyone calls "O&P" or "the 10 and 10," is one of the most misunderstood numbers in the whole file. It gets demanded where it doesn't belong, stripped where it does, and argued about by people who can't define it. Most reps know it's "ten and ten" and stop there.

Let's go deeper than that. We'll cover what overhead and what profit each actually are (they're two different things stapled together), where the 10-and-10 convention comes from, when O&P is genuinely owed and when it isn't, the "three trades" rule of thumb and why it's a guideline and not a law, how it interacts with the rest of the estimate, the worked math line by line, how to document a job so the O&P is defensible on its face, the mistakes that cost contractors this money, and the hard compliance line on what you can and can't say or do around it.

A scope note before we start, because it matters on every claim-adjacent topic. Everything here is about understanding and documenting your own estimate accurately, so that when O&P belongs on it, it's there and it's defensible. It is not about negotiating, adjusting, or handling anyone's insurance claim. The homeowner files. The insurer decides coverage, including whether it pays O&P. You write an accurate estimate for your scope and document why each line, O&P included, reflects the real cost of doing the work right. We'll be specific about that line near the end, because it's where contractors get themselves in trouble.

What Overhead and Profit Actually Are

The phrase gets said so fast, "oh-and-pee," that people forget it's two separate concepts. They're billed together and usually expressed as matching 10% figures, but they pay for different things, and understanding the difference is what lets you justify the line instead of just asking for it.

Overhead

Overhead is the cost of running your business that you can't bill to any single job. It's there whether or not this particular roof exists. There are two kinds, and the distinction matters:

• General (or fixed) overhead: rent on the office, the yard, insurance (general liability, workers' comp, commercial auto), office salaries, your estimating software, your trucks' financing, accounting and legal, licensing, advertising. The lights stay on whether you sell one roof this month or forty. This is what the overhead percentage on an estimate is meant to recover, a fair share of the cost of having a real, insured, operating company that can show up and stand behind the work.
• Job (or direct) overhead: costs tied to a specific job but not to a specific material or labor line, the dumpster, the permit, the porta-john, temporary protection, supervision time, the project manager's hours coordinating the trades. On a clean estimate these are usually itemized as their own lines, not buried in the overhead percentage.

The O&P percentage at the bottom of an estimate is recovering general overhead, your share of the cost of being a company, spread across the jobs you run. It is not double-charging for the dumpster you already listed as a line item.

Profit

Profit is exactly what it sounds like: the money left for the business after every cost, direct and overhead, is paid. It's the return for taking on the risk, the capital, the warranty obligation, and the coordination of the work. It is not a slush fund or a markup for its own sake; it's the reason a business exists. A roofing company that runs at zero profit is a charity with ladders.

The reason overhead and profit get bundled is convention and convenience. Estimating platforms and carrier practices long ago settled on expressing both as a percentage applied to the subtotal of the trade work, and the customary figure for each is 10%.

The relationship in one line

Trade-work subtotal
  + Overhead (customarily 10% of subtotal)
  + Profit   (customarily 10% of subtotal)
  = Estimate total (before tax)

That's the structure. Everything else, when it applies, how it's documented, what carriers will and won't pay, is detail layered on top of those three lines.

Where the "10 and 10" Comes From

The ten-and-ten convention isn't a law and it isn't a building code. It's a long-standing customary figure for what a general contractor charges to coordinate and carry a project. The idea is that a GC who manages a job, hiring and scheduling subcontractors, carrying the insurance and the liability, supervising the work, and standing behind the finished result, earns roughly 10% to cover overhead and roughly 10% as profit for doing it. The number is customary, not mandated, and actual overhead and profit margins vary widely by company, region, and job complexity. But "ten and ten" became the shorthand because it's the round number the industry standardized around for general-contractor coordination.

Here's the crucial nuance most reps miss: the convention is rooted in general-contractor work, coordinating multiple trades. That origin is exactly why O&P is contested on roofing jobs. A simple roof replacement is arguably a single-trade job, the roofer does roofing. The customary justification for GC-level O&P is the coordination of multiple trades, and a one-trade job doesn't obviously involve that coordination.

That's the whole fight in one sentence. When a roof job genuinely requires coordinating several trades, the GC justification for O&P is clear. When it's a roofer doing roofing and nothing else, carriers frequently take the position that no general-contractor coordination occurred, so the general-contractor markup doesn't apply. Both positions have logic behind them. Which one holds on a given job depends on the facts of that job, which is why documentation, not argument, is what carries the day.

The compounding detail

One small but real point of confusion: is the 10-and-10 calculated as 20% all at once, or as 10% and then 10% on top of the first? Standard practice is to apply both to the same subtotal, additive, not compounding:

Subtotal:                 $10,000
Overhead (10% of 10,000):  $1,000
Profit   (10% of 10,000):  $1,000
Total:                    $12,000   (a flat 20%, not 21%)

Applying profit on top of the overhead-inflated number (10% of $11,000 = $1,100) would be compounding, and that's not the convention. It's two parallel 10% lines off the same base. Knowing this keeps your estimate matching the carrier's math instead of reading as $100 high for no reason.

When O&P Is Genuinely Owed (and When It Isn't)

This is the section worth slowing down for, because it's where the money and the mistakes both live. The honest answer to "does insurance pay O&P on a roof?" is: it depends on whether the job has the characteristics of a general-contractor-coordinated project, and it depends on the carrier and the policy. There's no universal yes or no, and any rep who tells you O&P is "always owed" or "never owed" is wrong.

The general-contractor logic

The cleanest way to think about it: O&P is owed when a reasonable homeowner, doing the same repair, would need (or would reasonably hire) a general contractor to coordinate it. The yardstick most carriers use internally for this is the complexity and number of trades involved.

A roof that's only a roof, tear off shingles, install shingles, is a single trade. The argument against O&P is that no general-contractor coordination is required: a roofer can do the whole job. The argument for O&P even on single-trade work is that a roofing company still carries real general overhead and earns a profit like any business, and the 10-and-10 is simply how that's expressed in this estimating convention. Carriers and contractors genuinely disagree here, and outcomes vary by carrier, by state regulatory environment, and by individual policy.

The "three trades" rule of thumb

You'll hear the three-trades rule constantly on storm jobs: the idea that O&P is owed when a job involves three or more separate trades, because at that point coordination genuinely requires general-contractor oversight. Roofing plus gutters plus a siding repair plus interior drywall from a leak, that's multiple trades, scheduling, and supervision, and the GC justification for O&P becomes clear.

Understand what the three-trades rule actually is: a rule of thumb, a common internal guideline many adjusters use, not a statute or a binding standard. There is no law that says "three trades equals O&P." Some carriers use a different threshold; some look at overall complexity rather than a strict count; some pay O&P on any roof of meaningful size. Treat "three trades" as a useful framing for why coordination justifies the markup, not as a magic number you can wave to force payment.

What counts as a separate trade for this framing typically means genuinely different skill sets and crews, for example:

• Roofing (shingles, underlayment, flashing)
• Gutters and downspouts
• Siding
• Painting
• Interior repairs (drywall, insulation, paint from interior water damage)
• HVAC (a hail-damaged condenser is a different trade)
• Window or screen replacement
• Detached structures (a separate-trade detached garage or shed adds coordination)

The test isn't "can I list three line items." It's "does this job genuinely require coordinating distinct trades the way a general contractor would." Padding a trade count, listing "painting" for a single touch-up to manufacture a third trade, is the kind of move that gets a whole file scrutinized and your credibility burned.

Factors that strengthen the case for O&P

Beyond a clean trade count, these characteristics make the general-contractor justification more clearly applicable:

• Genuine multi-trade coordination. Several distinct crews that have to be scheduled around each other.
• Job complexity. Steep and complex roofs, multiple structures, significant interior involvement, anything that genuinely requires project management.
• Permitting and inspection coordination across trades.
• Supervision requirements. A job that needs a project manager on site coordinating sequencing.
• Size and duration. A large, multi-day, multi-crew job carries coordination cost a one-day single-crew tear-off doesn't.

Factors that weaken it

• Single trade, single crew, single day. A straightforward roof-only replacement.
• No coordination required. One crew shows up, does the roof, leaves.
• Self-performed work with no subcontractor management. If you're not coordinating other trades, the GC-coordination justification is thinner.

None of this means a roofing company doesn't deserve to make a profit on a simple roof, of course it does, and it builds that into its unit pricing. The question on the table is narrower: whether the general-contractor 10-and-10 markup convention applies, which is a different question from whether you make money on the job.

How O&P Interacts With the Rest of the Estimate

O&P doesn't sit alone. It's the last layer on a stack, and several other lines interact with it. Getting the order of operations right keeps your estimate matching the carrier's and keeps you from accidentally over- or under-stating the total.

What O&P is applied to

The customary practice is to apply the O&P percentage to the subtotal of the trade work, the labor, material, and equipment that make up the actual repair. Where it gets fuzzy is the items that sometimes do and sometimes don't get included in the base:

The practice that varies most is permits and other pass-through costs. Many carrier platforms exclude permit fees from the O&P base because they're a flat governmental pass-through, not work you're marking up. Don't assume; know how your estimating platform and the carrier handle it so your number lines up.

Order of operations

The standard sequence on a storm estimate:

1. Trade-work subtotal (labor + material + equipment)
2. + Overhead (10% of subtotal)
3. + Profit   (10% of subtotal)
4. + Permits / pass-through items (if excluded from O&P base)
5. + Sales tax (applied per local rules)
   = RCV total
6. − Depreciation        = ACV
7. − Deductible          = first check (on an RCV policy, with
                           recoverable depreciation released later)

Notice O&P lands before depreciation and the deductible. That matters: because O&P is part of the RCV, it's part of the number depreciation is calculated against and part of what recoverable depreciation eventually releases on an RCV policy. O&P isn't a separate bucket that pays out independently, it's woven into the RCV, so it flows through the same ACV/recoverable-depreciation structure as everything else. If you don't understand that interaction, see the companion breakdown of ACV vs RCV on roof claims; it's the structure O&P rides on.

O&P and supplements

When you supplement a scope, discovered decking, an extra layer, code items that surfaced at tear-off, the O&P generally applies to the supplemented work too, because it's part of the same coordinated job. A supplement that adds $2,000 of legitimate trade work, on a job where O&P applies, carries its proportional O&P. Build that into how you write supplements so you're not leaving the markup off the additional scope by accident.

Worked Examples (Real Numbers, Line by Line)

Abstract percentages don't stick. Here are three scenarios you'll actually see, so the differences are concrete.

Example 1: Single-trade roof, O&P contested

A straightforward architectural-shingle replacement, roof only, one crew, one day.

Tear-off (labor):                    $2,400
Shingles + underlayment (material):  $6,200
Accessories, flashing, vents:        $1,100
Disposal:                              $600
Labor (install):                     $3,500
--------------------------------------------
Trade subtotal:                     $13,800

If O&P is NOT applied (carrier position: single trade):
  RCV (before tax):                 $13,800

If O&P IS applied (10 + 10 on subtotal):
  Overhead (10%):                   $1,380
  Profit   (10%):                   $1,380
  RCV (before tax):                 $16,560

The $2,760 swing is entirely the O&P question. On a roof-only job, this is exactly where the carrier and contractor disagree, and it's resolved on the facts of the job and the carrier's practice, not by demanding it. Your job is to write the estimate accurately and document the scope; whether O&P applies is a coverage call.

Example 2: Multi-trade storm job, O&P clearly applicable

Same hailstorm, but this house took it harder: roof, gutters, a damaged section of siding, and interior drywall and paint from a ceiling leak.

Roofing (trade 1):                  $13,800
Gutters & downspouts (trade 2):      $2,100
Siding repair (trade 3):             $3,400
Interior drywall/paint (trade 4):    $1,900
--------------------------------------------
Trade subtotal:                     $21,200

Four distinct trades, genuine coordination required.
  Overhead (10%):                   $2,120
  Profit   (10%):                   $2,120
  RCV (before tax):                 $25,440

Four trades that must be scheduled around each other, the dry-in before interior repairs, gutters after roof, paint last, is the textbook general-contractor coordination the 10-and-10 convention was built for. Here the O&P justification is clear, and your documentation should make the coordination visible: the trade breakout, the sequencing, the supervision.

Example 3: Two-and-a-half trades, the judgment call

Roof plus gutters plus a single small soft-metal/painting touch-up. This is where contractors get themselves in trouble by trying to manufacture a third trade.

Roofing (trade 1):                  $13,800
Gutters (trade 2):                   $2,100
Minor paint touch-up:                  $250
--------------------------------------------
Trade subtotal:                     $16,150

Is the $250 paint touch-up a genuine third trade that adds coordination, or a line you're stretching to clear the three-trades rule of thumb? Honestly, it's borderline, and trying to leverage a $250 line into a $3,230 O&P claim is the kind of move that invites scrutiny on the whole file. The defensible posture: write the scope accurately, let the trade count be what it actually is, and document the real coordination if there is any. Don't bend a touch-up into a trade to game a guideline. The credibility you keep is worth more than the markup you'd force.

What these examples teach

The trade work in your estimate should be identical regardless of the O&P question, you scope and price the repair the same way every time. O&P is a layer that applies, or doesn't, based on the genuine character of the job. Your job is consistent across all three: scope accurately, price defensibly, document the coordination honestly, and let the carrier apply its O&P practice to the facts you've documented. You don't force it; you make it self-evident when it's real.

The Vocabulary People Mix Up

Half the O&P confusion is people using the same words to mean different things. Here's the working glossary so you and the adjuster are talking about the same thing.

Keep these straight and your conversations get cleaner. Most O&P disputes that feel like coverage fights are actually two people meaning different things by "overhead" or counting "trades" differently.

Overhead in the unit price vs O&P as a line

One distinction that causes real arguments: some pricing already bakes a measure of overhead into the unit prices, and then O&P is added on top as the general-contractor coordination markup. Carriers will sometimes argue you're "double-dipping" overhead. The clean way to think about it: unit-price overhead (if present) covers the direct cost structure of performing that line of work; the O&P percentage covers general-contractor coordination of the overall job. They're conceptually different layers. Whether both apply on a given job is, again, a function of the job's character and the carrier's practice, documented, not argued.

Documentation That Makes O&P Defensible

Here's the operating principle: you don't win O&P by arguing for it, you make it self-evident by documenting the job so the coordination is visible on the face of the estimate. An adjuster applying a three-trades-or-complexity guideline can see, from a well-built file, whether the job qualifies. A sloppy file forces a judgment call that defaults against you. Build the file so the answer is obvious.

Break out the trades clearly

The single most important documentation move: itemize the estimate by trade, not as one undifferentiated list. When roofing, gutters, siding, and interior repair are visually separated into distinct trade sections, the multi-trade nature of the job is self-evident. Burying a siding repair as one line in a long roofing list hides the very thing that justifies the markup.

TRADE 1 - ROOFING
  [line items]
TRADE 2 - GUTTERS & DOWNSPOUTS
  [line items]
TRADE 3 - SIDING
  [line items]
TRADE 4 - INTERIOR (drywall/paint, water damage)
  [line items]

That structure does the explaining for you.

Document the coordination, not only the trades

A trade count alone isn't the whole story; the coordination is what O&P pays for. Note in the file the things that require management:

• Sequencing dependencies: the roof has to be dried-in before interior repairs; gutters go after the roof; paint is last. Sequencing is coordination.
• Scheduling of distinct crews across multiple days.
• Permitting and inspections that span trades.
• Supervision: if a project manager is on site coordinating, note the role.
• Duration: a multi-day, multi-crew job carries real coordination cost; a one-day single-crew job doesn't.

Photograph the multi-trade damage

The photo set that supports the scope also supports the trade count. If you're claiming gutters, siding, and interior as separate trades, the file needs photos that establish damage in each:

• Roof: marked test squares, individual functional hits with a scale reference, soft-metal and collateral corroboration.
• Gutters/downspouts: the dents and damage that justify the gutter trade.
• Siding: the damaged sections, with scale.
• Interior: the ceiling stain, the drywall damage, the source traced to the roof leak.

Each trade you bill should have damage documentation behind it. A trade asserted on the estimate with no damage photo behind it is the thing that gets the O&P, and the trade, struck.

Use the carrier's estimating platform and defensible pricing

Write the estimate in the platform the carrier uses where you can, with line items mapped to a recognized pricing database and kept aligned to current local pricing. When your unit prices and your structure already match the carrier's reference, the only thing left to evaluate is the scope and the O&P, and a clean, trade-segmented, well-photographed scope makes the O&P read as obviously applicable when it is.

Write the estimate honestly

This is the non-negotiable. Document the trades that genuinely exist, the coordination that genuinely happens, the damage that's genuinely there. Manufacturing a third trade, inventing coordination on a one-crew job, or padding to clear a guideline is fraud, and it's the surest way to get the whole file, not only the O&P, denied. A complete, honest, well-segmented file wins the legitimate O&P more reliably than any padded one, because it survives the look.

What Pros Get Wrong

After enough storm seasons, the same O&P mistakes show up on the same kinds of jobs. Here are the costly ones.

Treating O&P as automatic

Newer reps learn "always add ten and ten" and slap it on every estimate, including roof-only single-trade jobs where the carrier's position against it is strong. When it gets stripped, they argue, lose credibility, and sometimes get the rest of the scope scrutinized harder. O&P is situational. Add it where the job's character supports it; document why; don't treat it as a reflex.

Treating O&P as never-payable

The opposite mistake: a rep gets told "we don't pay O&P" once, believes it's a blanket rule, and leaves the markup off a genuinely multi-trade, coordination-heavy job where it clearly belonged. "We don't pay O&P" is a position, not a law of physics, and on a real four-trade job, the contractor who documents the coordination and includes the O&P is writing an accurate estimate. Folding pre-emptively leaves real money the homeowner was owed on the table.

Manufacturing trades to hit "three"

Stretching a $200 touch-up into a "painting trade" to clear the three-trades rule of thumb is the move that gets files flagged. The three-trades framing is a guideline about genuine coordination, not a checklist to game. Forced trade counts invite scrutiny and torch credibility, and the scrutiny lands on your whole scope, not only the stretched line.

Hiding the multi-trade nature in one long list

A genuinely multi-trade job written as one undifferentiated list of line items hides the very thing that justifies O&P. The adjuster can't see four trades in a wall of roofing lines. Segment by trade and the justification documents itself.

Not understanding that O&P rides inside the RCV

Reps who think O&P is a separate bucket get confused when it gets depreciated along with everything else, or when the recoverable-depreciation second check (on an RCV policy) includes the O&P portion. O&P is part of the RCV; it flows through the same ACV-first, depreciation-released-after-completion structure as the rest of the scope. Know how it interacts so you set honest expectations.

Confusing job overhead with the O&P percentage

Listing the dumpster, permit, and supervision as line items and expecting the O&P percentage to cover those same job-specific costs double-counts. The O&P percentage recovers general overhead and profit; job-specific overhead is itemized separately. Mixing them up either double-charges (which gets struck) or leaves job costs uncovered.

Promising the homeowner an O&P outcome

Telling a homeowner "I'll get you O&P" or "the insurance has to pay overhead and profit" is a promise about a coverage outcome you don't control, and it edges toward representing the homeowner's claim. Write the estimate accurately; document the job; let the carrier decide. Promising the outcome is where helpful tips over into the lane you can't be in.

Chasing the wrong roofs in the first place

The most expensive O&P mistake happens before the estimate exists: spending the day documenting and estimating roofs that were never going to pencil out, too new to have a qualifying scope, or under a storm that didn't actually hit hard enough. All the O&P expertise in the world is wasted on a door that was never a job. More on solving that below.

O&P and the Damage File Itself

None of the O&P math matters if the underlying damage documentation doesn't establish a covered loss and a complete scope in the first place. O&P is a markup on the trade work; if the trade work isn't documented and justified, there's nothing for O&P to apply to. So the damage file is upstream of the whole O&P question.

The distinction that decides most asphalt-shingle hail scopes is functional versus cosmetic damage, and it governs how much legitimate trade work, and therefore how much O&P base, the job carries.

Functional hail damage to an asphalt shingle is impact that fractures the mat and dislodges granules, exposing the asphalt and shortening the roof's life. The signature is a bruise, a soft spot you can feel, with granule loss and a fractured mat underneath. That's the damage that supports a full-replacement scope. Cosmetic marks, scuffs, blistering, foot-traffic granule loss, manufacturing irregularities, don't impair function and aren't storm damage.

Document them differently:

• Functional hits: mark, circle, and photograph with a scale reference (chalk circle, coin, tape, pen). Record functional hits per 100 sq ft test square per slope.
• Cosmetic or pre-existing marks: photograph honestly and label as such. Mislabeling cosmetic as functional is the fastest way to get a file denied and your credibility gone, and a denied scope means no O&P at all.

Corroborating the storm and the trades

Real hail of a damaging size leaves a trail across the property, and that trail both supports the roof scope and establishes the other trades that justify O&P:

• Soft metals: dents in gutters, downspouts, valley metal, vents, furnace caps, and AC-condenser fins. Soft metals dent at smaller hail sizes than shingles fracture, so they're sensitive indicators, and gutter damage is its own trade.
• Collateral: dinged window screens, garage doors, fence caps, deck boards, painted wood, establishing hail of a given size and direction, and sometimes a separate trade (siding, paint, screens).
• Directionality: hail comes in at an angle, so damage concentrates on storm-facing slopes and elevations. A file where the roof, soft-metal, and collateral findings all point the same direction is internally consistent and credible.

Wind damage tells a different story, creased, torn, or missing shingles, lifted tabs with broken sealant bonds, displaced ridge caps. Document creasing specifically: a crease is a fracture line that won't reseal, which is functional even if the shingle is still up there.

The goal is a file that's internally consistent, roof findings matching soft-metal findings matching collateral matching the storm's reported size and direction, and where the separate trades each have damage behind them. A consistent, well-documented multi-trade file is what makes a multi-trade scope, and the O&P on it, read as legitimate. An inconsistent one invites a denial and deserves one.

Edge Cases That Wreck Jobs

"We pay O&P only with three trades," applied rigidly

Some adjusters apply the three-trades rule as a hard gate. If your job is genuinely complex with two trades plus heavy coordination, the rule-of-thumb gate can cut against a real coordination cost. Document the coordination thoroughly; the three-trades framing is a guideline, and a well-documented complex two-trade job has a stronger case than a thin three-trade one. But don't manufacture a trade to clear the gate, document reality and let it stand on its merits.

O&P stripped on resubmission

A scope comes back with the O&P removed and a note like "single-trade work, O&P not applicable." If the job genuinely is single-trade, that's a defensible carrier position. If it's genuinely multi-trade and the stripping is based on a misread of the scope, the fix is documentation, a clearer trade breakout, photos establishing each trade, not an argument. You're not negotiating; you're submitting a clearer factual picture of the scope you're doing.

Self-performed multi-trade work

What if you self-perform all the trades, your own crews do the roof, gutters, and siding, rather than subbing them out? The coordination still exists (you're still scheduling and supervising distinct crews and skill sets), but carriers sometimes argue O&P is for subcontractor coordination specifically. Practice varies. Document the genuine coordination either way; the existence of distinct trades and the need to manage them is the substance, regardless of whether the crews are yours or subs.

Percentage already in the price database

If your estimating platform's unit prices already embed some overhead, an adjuster may argue adding a separate 10% overhead double-counts. The distinction (unit-level cost structure vs general-contractor coordination of the whole job) is real but easy to muddy. Know what your database includes so you can document the difference accurately rather than getting tagged for double-dipping.

Very small jobs

On a small repair, $800 of trade work, the customary 10-and-10 is $160, and the coordination justification is thin because there's barely a job to coordinate. Forcing O&P onto a tiny single-trade repair is exactly the reflex that gets flagged. Match the markup to the genuine character and size of the work.

Tax and the order of operations

Applying O&P after tax, or tax before O&P incorrectly, throws the total off and makes your estimate not match the carrier's math. Sales tax is applied per local rules, generally after O&P, on the appropriate base. Get the order right so the only thing under discussion is the scope and the O&P, not an arithmetic mismatch you introduced.

Where RoofPredict Fits

Everything above is about handling a roof, and its estimate, once you're standing on it. The harder, more expensive problem is which roofs to stand on in the first place, and that's upstream of any O&P line.

The O&P math has a quiet implication: the jobs where O&P genuinely applies, the bigger, multi-trade, storm-driven scopes, tend to be roofs that are both aged into a replaceable window and actually hit by a storm hard enough to produce multi-trade damage. A four-year-old roof that caught pea-sized hail isn't generating a four-trade scope with defensible O&P. A sixteen-year-old roof under a corridor that took 1.5-inch hail and damaged the gutters, siding, and an interior ceiling is exactly the kind of job where the full coordinated scope, and the O&P on it, is real. If you're knocking doors blind, you're spending most of your day on roofs that were never going to produce that kind of job.

RoofPredict is built for that targeting step. It gives you, house by house:

• A roof-age estimate as a range (from aerial imagery), not a guaranteed install date, so you can see which roofs are aging into the window where a meaningful storm scope is plausible.
• Storm physics modeled per roof, hail size and wind exposure mapped to the specific address, so you can prioritize the roofs a given event actually wore on rather than a whole zip code.
• Enrichment of your own list or CRM with those age and storm signals, so the doors and mailers you were already going to work get ranked by which are most likely due.

That ranking is what cuts the wasted-doors cost flagged in the mistakes section. Instead of canvassing a street uniformly, your crew hits the roofs where age and storm exposure line up, the ones most likely to produce a real, documentable, sometimes multi-trade scope.

Honest limits, because hype helps no one: an age range from imagery is not a birth certificate, you still verify on site. A storm model is odds, the likelihood a roof was affected, not proof of covered damage, and it never tells you what a policy covers, whether O&P applies, or what a carrier will approve. RoofPredict points you at the roofs most worth inspecting and documenting; the inspection, the trade-segmented estimate, the O&P justification, and the carrier's coverage decision all still happen the normal way. It sharpens your targeting; it does not replace your judgment on the roof or your craft on the file.

The Line You Do Not Cross

This is the part that keeps contractors in business and out of trouble. Understanding O&P makes you better at writing an accurate estimate, and it puts you near a line you must not cross. In most states, negotiating, adjusting, or "handling" someone's insurance claim for compensation is public adjusting, and it requires a license roofing contractors generally don't hold. Arguing O&P on the homeowner's behalf as a coverage fight is exactly the kind of activity that can tip you over that line.

Here's the clean division of labor:

What you CAN do:

• Write an accurate, defensible estimate for your scope, including O&P where the job's character supports it, with line items mapped to recognized pricing.
• Document the trades, the coordination, the sequencing, and the damage so the estimate is self-evident on its face.
• Explain, in general and factual terms, what overhead and profit are and how the 10-and-10 convention works, so a homeowner understands their own paperwork.
• State facts about your scope and your coordination to the carrier when you're the one doing the work.
• Resubmit a clearer, better-documented estimate if a scope was misread, that's submitting facts, not negotiating coverage.

What you CANNOT do (the do-not-say / do-not-do list):

• Negotiate or "handle" the claim for the homeowner, including arguing O&P as a coverage entitlement on their behalf. That's adjusting.
• Interpret policy or coverage. Don't tell a homeowner their policy "requires" O&P or what it covers for their specific loss. Point them to their carrier.
• Promise a specific payout, approval, or that O&P will be paid. You don't control the carrier's decision.
• Promise the deductible is waived, absorbed, eaten, or "covered" by the O&P or anything else. Waiving or rebating a deductible is illegal in many states and is insurance fraud. The homeowner owes their deductible, regardless of O&P.
• Advertise a "free roof" or "no out-of-pocket." It's misleading and implies the deductible vanishes, which it doesn't.
• Represent the homeowner against the insurer. You document your scope and estimate; you don't argue their coverage for them.

The mental model: you're the expert on the roof and the estimate. The homeowner owns the claim. The carrier owns the coverage decision, including whether it pays O&P. Stay in your lane and you can be enormously helpful, document better than anyone, write a tighter, trade-segmented estimate, set honest expectations about O&P and depreciation, without ever touching the activities that require an adjuster's license. Cross it, and a single complaint can put your license and your company at risk.

When in doubt, narrate the structure and hand off the decision: "Here's generally how overhead and profit work on a job like this, and here's a complete estimate with the trades documented; whether and how O&P is paid is between you and your carrier." That sentence keeps you helpful and compliant at the same time.

A Practical Checklist for Every Storm Job

Run this on every claim-adjacent job and you'll handle O&P accurately and stay inside the line:

1. Before the estimate: Identify the genuine trades the storm produced, roof, gutters, siding, interior, HVAC. Count what's real, not what you wish were there.
2. On the roof and property: Full photo set with scale references, marked test squares, soft-metal and collateral corroboration, plus damage photos for every trade you intend to bill.
3. Build the estimate by trade: Segment roofing, gutters, siding, interior into distinct sections so the multi-trade nature is self-evident. Defensible unit prices, code items cited, nothing padded, nothing omitted.
4. Apply O&P where it belongs: 10 and 10 on the trade subtotal, additive not compounding, when the job's character (genuine multi-trade coordination, complexity, supervision) supports it. Document the coordination, sequencing, scheduling, supervision. Leave it off where the job is genuinely single-trade and the case is thin.
5. Get the order of operations right: O&P before depreciation and deductible; permits/pass-throughs and tax handled per the platform and local rules.
6. Set expectations honestly: Explain what O&P is in general terms; note it rides inside the RCV and flows through the same ACV/recoverable-depreciation structure. Don't promise it'll be paid. Be clear the homeowner owes the deductible regardless.
7. Stay in your lane: Document and estimate. Let the homeowner file and the carrier decide coverage, O&P included. Never negotiate, interpret coverage, promise payout, or touch the deductible.

Putting It Together

Overhead and profit isn't insurance trivia, and it isn't an automatic 20% you bolt onto every estimate. Overhead is your share of the cost of being a real, insured, operating company. Profit is the return that keeps that company alive. The customary 10-and-10 is the general-contractor markup for coordinating a job, which is why it's clearest on multi-trade, coordination-heavy scopes and genuinely contested on single-trade roof-only work. The three-trades rule is a useful guideline about when coordination justifies the markup, not a law you can wave to force payment.

The move that wins legitimate O&P isn't argument, it's documentation: scope and price the trade work honestly, segment the estimate by trade so the coordination is self-evident, photograph the damage behind every trade you bill, get the order of operations right, and let the carrier apply its O&P practice to a file that makes the answer obvious. Don't manufacture trades, don't force the markup onto thin jobs, and don't promise a homeowner an O&P outcome you don't control.

Do that consistently and you separate yourself from every rep who reflexively slaps ten-and-ten on a single-shingle repair and from every rep who folds the moment an adjuster says "we don't pay O&P." You become the contractor whose estimates are accurate, whose files are clean, and whose O&P, when it's there, is obviously earned.

The targeting question, which roofs are worth this whole workflow in the first place, is where age and storm data earn their keep. Roofs aging into the replaceable window, under storms that actually hit that address hard enough to produce real, multi-trade, O&P-bearing scopes, are where your documentation effort pays off. RoofPredict is built to rank exactly those doors so your crews spend their hours on the roofs most likely due, then you do what you already do well: document thoroughly, build a trade-segmented estimate with the O&P where it belongs, and let the homeowner and their carrier handle the claim.

FAQ

What does O&P mean on a roofing insurance estimate?

O&P stands for overhead and profit, two separate line items usually expressed as matching 10% figures (the "10 and 10"). Overhead is your share of the general cost of running an insured, operating business (office, insurance, trucks, software), spread across jobs. Profit is the business's return after all costs. On an estimate, the 10-and-10 is the customary general-contractor markup applied to the trade-work subtotal to cover coordinating and carrying the job.

Does insurance always pay overhead and profit on a roof claim?

No. Whether O&P is owed depends on the job's character and the carrier's practice. The 10-and-10 convention is rooted in general-contractor coordination of multiple trades, so it's clearest on complex, multi-trade storm jobs and genuinely contested on single-trade, roof-only replacements where the carrier may argue no general-contractor coordination occurred. There's no universal rule; it's decided on the facts of the job and the policy.

What is the three-trades rule for O&P?

The three-trades rule is a common rule of thumb that O&P applies when a job involves three or more distinct trades, because coordinating that many trades requires general-contractor oversight. It's a widely used internal guideline, not a law or binding standard. Some carriers use different thresholds or look at overall complexity. Treat it as a framing for why coordination justifies the markup, not a magic number, and never manufacture a trade to clear it.

Is O&P calculated as 20% all at once or 10% plus 10% compounded?

Standard practice is to apply both 10% figures to the same trade-work subtotal, additive, not compounding. So a $10,000 subtotal carries $1,000 overhead and $1,000 profit for a $12,000 total, a flat 20%, not 21%. Applying profit on top of the overhead-inflated number would be compounding and isn't the convention.

What does the O&P percentage get applied to?

The customary practice applies the O&P percentage to the trade-work subtotal, labor, material, and equipment for the repair. Permits and other governmental pass-through costs are often excluded from the O&P base, and sales tax is applied after O&P rather than being part of the base. Practice varies by estimating platform and carrier, so confirm how yours handles permits and tax so your total matches.

Does O&P get depreciated like the rest of the estimate?

Yes. O&P is part of the Replacement Cost Value (RCV), so it's included in the number depreciation is calculated against and, on a replacement cost policy, is part of what the recoverable-depreciation second check eventually releases after the work is completed and proven. O&P isn't a separate bucket that pays out independently; it rides inside the RCV and flows through the same ACV-first, depreciation-released-after-completion structure as everything else.

Can a roofing contractor argue O&P with the insurance company?

A contractor can write an accurate estimate that includes O&P where the job's character supports it and resubmit a clearer, better-documented estimate if the scope was misread, that's submitting facts. A contractor should not negotiate or argue O&P as a coverage entitlement on the homeowner's behalf, interpret the policy, or promise it will be paid; that edges into public adjusting, which generally requires a license. Document the trades and coordination and let the carrier decide.

Why was O&P removed from my estimate on resubmission?

Usually because the carrier read the scope as single-trade work where general-contractor coordination isn't required, which is a defensible position on a roof-only job. If the job is genuinely multi-trade and the stripping is based on a misread, the fix is better documentation, a clearer trade-by-trade breakout and photos establishing each trade, not an argument. If the job genuinely is single-trade, the carrier's position may simply hold.

Does self-performed multi-trade work still justify O&P?

The coordination still exists when your own crews handle distinct trades like roofing, gutters, and siding, you're still scheduling and supervising different crews and skill sets. Some carriers argue O&P is specifically for subcontractor coordination, so practice varies. Document the genuine coordination either way; the existence of distinct trades and the need to manage them is the substance, regardless of whether the crews are yours or subcontracted.

Can a contractor tell a homeowner the insurance has to pay O&P?

No. Telling a homeowner the insurer "has to" pay O&P is a promise about a coverage outcome the contractor doesn't control and edges toward interpreting coverage and representing the claim. A contractor can explain in general terms what overhead and profit are and provide a complete, well-documented estimate, then let the homeowner file and the carrier decide. Whether and how O&P is paid stays between the homeowner and their carrier.
