The adjuster approved a partial roof replacement. The estimate you wrote covered the whole roof. The gap between those two numbers is now yours to deal with, and nobody is going to hand you a plan for it.
Here is the part that costs roofers money. A partial approval feels like a problem with the insurance company. It is actually a decision about your job. The homeowner is holding a check that does not match the scope, and she is looking at you to tell her what happens next. What you say, and what you choose to do, sets your margin on this job.
You have probably lived at least one of these:
- •The approval letter lands on a Thursday, and the job you scheduled for Monday is suddenly a question mark.
- •She asks if you can just do the part they will pay for, and you say yes before you have run the math.
- •You offer to make a call, and three weeks later the crew day you held is gone and nothing has changed.
- •You discount the gap a little to save the job, and find out at final invoice that the margin went with it.
- •You do the approved section, and the callback comes from the slope you did not touch.
None of those were bad instincts. They were decisions made without numbers.
A partial approval gives you three real options: finance the gap, contest the approval, or do a fractional repair. Each one costs you something different in cash, time, and callback risk. Here is how to run the numbers on each one before you pick.
What a Partial Approval Does to Your Job Math
A partial roof replacement approval does not change what the job costs you. It changes who is paying for it.
Why a carrier approved less than you priced depends on the policy, the state, and the file. This post does not argue that question. It starts from the approval as written and asks what you do with it.
The math is simple. Here is an illustrative job. These are not industry figures. They are round numbers to show the mechanics.
| Line | Illustrative job |
|---|---|
| Your full-scope price | $18,400 |
| Approved amount | $11,200 |
| The gap | $7,200 |
| Your cost at full scope (30% margin) | $12,880 |
| Result if you do full scope for the approved amount | Loss of $1,680 |

Line: Approved amount
- Illustrative job
Line: The gap
- Illustrative job
Line: Your cost at full scope (30% margin)
- Illustrative job
Line: Result if you do full scope for the approved amount
- Illustrative job
Read the last line twice. At a 30% margin, a $7,200 gap does not just erase your gross profit of $5,520. It puts you $1,680 under water on direct job cost, before a dollar of overhead.
That is not an insurance problem. That is a margin problem.
Every option on this job is a way to close that $7,200. Either the homeowner pays it, the carrier pays it, or the scope shrinks until it does not exist. Those are the three real moves. Eating the gap yourself is a fourth, and the table above is why it is not on the list.
Before you pick, write down three numbers: the gap, your margin at full scope, and the crew days this job will hold on your calendar. Everything that follows runs on those three.
Option One: Finance the Gap
The first move is to help the homeowner cover the $7,200 herself, for example through a financing program. Nothing about the carrier changes. You are turning an insurance job into a job with a retail balance on top.
That has a cost to the close. She was expecting the check to cover the roof. Now she owes $7,200 she did not plan for, and she is deciding whether to say yes with a number she has had for a few days. If she goes quiet, the objection she will not say out loud is probably money, and that post covers how to bring it up.
Here is what it does to your numbers. Suppose the program charges you a 5% fee on the financed amount. That figure is illustrative. Get your actual fee in writing before you quote anything.
- •5% of $7,200 is $360.
- •Your gross profit drops from $5,520 to $5,160.
- •Your gross margin drops from 30% to 28%.
That is $360 on an $18,400 job, 2% of the price. The bigger cost is time. If she cannot say yes by Friday, the job is not closed. It is stalled, and it is holding crew days you could sell.
Two cautions. If you carry the balance yourself instead of using a program, you are the bank, and your cash flow absorbs the wait. And do not shave the price to make the gap look smaller without running the new number through the same table.
Finance the gap when:
- •the roof genuinely needs the full scope
- •she can realistically be approved
- •the fee still leaves your margin intact
Option Two: Contest the Approval
The second move is to ask the carrier for more. This post does not teach you how to build that case. The post on documenting what the first inspection missed covers the documentation side. Whether your partial approval fits that situation depends on why the carrier approved less, and that is a question for your file, not for this post.
This section covers the part that never shows up in the file: what contesting costs you.
- •The timeline is not yours. — How long a carrier takes to respond varies by carrier and by state. You are scheduling around a date you do not control.
- •Your crew days are the first bill. — Take your crew-day number. That is only a real cost if the held days go unsold. If you can rebook them, the cost drops to near zero. If you cannot, it is the price of the wait.
- •Your own hours are the second bill. — Every call you make on this file is a call you did not make on a new estimate.
- •The roof stays as it is. — While the contest runs, the damaged roof stays damaged, and she may be deciding whether to keep waiting or call someone who will start now.
Now run it. The example crew in the crew cost post comes to $1,056 for one three-person crew. Say the decision takes three weeks and you hold two crew days at $1,056. That is $2,112 of crew expense waiting on a letter. If those days go unsold, the contest pays for itself only once you recover $2,112 of the $7,200 gap. That is 29%, before you count your own hours.
A recovery you cannot put a probability on is not a number. So use your own files. Of the partial approvals you have contested, how many came back with more money, and how much more? That is your odds. Nobody else's statistic belongs in this decision.
Contest windows and procedures vary by carrier and state. Check your state's insurance department before you tell a homeowner anything about timing.
Contest the approval when:
- •the gap is large compared to your margin
- •your file gives you a documented basis, not just a feeling
- •you can rebook the held crew days
Option Three: A Fractional Repair
The third move is to do the work the approval pays for and nothing more. A fractional repair is a partial roof replacement scoped to the approved number. There is no gap to close and no waiting on the carrier. The job is smaller, and it closes on the number already approved.
Here is the illustrative math. Suppose the approved $11,200 covers the slopes you can do at your normal price, at your normal 30% margin.
- •Cost: $7,840
- •Gross profit: $3,360
That is $1,800 less gross profit than the financed full-scope job. In exchange, you carry no financing fee and no wait on the carrier, and the job can go on the calendar as soon as she signs.
The cost shows up later, if it shows up. Say one callback takes a full crew day. In the example, that is $1,056, or 31% of the $3,360 you made on the job. Two callbacks cost $2,112, which is 63%.
When a fractional repair is honest:
- •the remaining roof has real life left, and you can say so from what you saw on the roof
- •the damage is localized, not a symptom of an aging roof
- •the scope is written in the contract down to the slope, including what you did not replace
When it creates a callback:
- •the untouched slopes are near the end of their life, and the first leak is blamed on your work
- •the homeowner expected a roof, not a section of one
- •you discounted the price to make it feel like a full replacement
Check what the shingle manufacturer's warranty says about a partial install before you quote it. Do not assume the answer.
How to Pick Your Move on a Given Job
Put the three options side by side on the illustrative job.
| Option | Gross profit, best case | What the move costs you | Main risk |
|---|---|---|---|
| Finance the gap | $5,160 | $360 fee | She stalls and the days sit |
| Contest the approval | $5,520 if the full gap is recovered | $2,112 if two crew days go unsold, plus your hours | The recovery never comes and the roof waits |
| Fractional repair | $3,360 | $1,056 per full-day callback | A callback from the slopes you did not touch |
Option: Finance the gap
- Gross profit, best case
- What the move costs you
- Main risk
Option: Contest the approval
- Gross profit, best case
- What the move costs you
- Main risk
Option: Fractional repair
- Gross profit, best case
- What the move costs you
- Main risk
No option wins on every column. Underneath all three sits one question: partial vs full roof replacement on this specific roof. Answer these three questions about the job, and they tell you which move is available.
- •Does the roof need the full scope? — If the untouched slopes have real life left, a fractional repair is honest. If they do not, it is a callback you have already scheduled.
- •Can she cover the gap? — If she can and she will say yes, financing keeps the full scope without waiting on the carrier. If she cannot, you are back to the other two.
- •Can you document a basis and rebook the days? — Contesting only makes sense when the file supports it and the held days do not sit idle.
| Job condition | Lean toward |
|---|---|
| Roof needs the full scope, and she can cover the gap | Finance the gap |
| Roof needs the full scope, she cannot cover the gap, your file supports it, and you can rebook the days | Contest the approval |
| Roof does not need the full scope: damage is localized and the untouched slopes have real life left | Fractional repair |
| Roof needs the full scope, she cannot cover the gap, and you cannot document a basis or rebook the days | Decline the full scope at the approved price |
Job condition: Roof needs the full scope, and she can cover the gap
- Lean toward
Job condition: Roof needs the full scope, she cannot cover the gap, your file supports it, and you can rebook the days

Job condition: Roof does not need the full scope: damage is localized and the untouched slopes have real life left

The last row matters. Doing the full scope for the approved $11,200 loses $1,680 on direct job cost, as the first table showed. That is not a fourth option. That is a loss with a number on it, and it is one more way a roofing company's margin disappears.
The questions tell you which move is available. The numbers tell you whether it pays. Write down the gap, your margin at full scope, and your crew days, then pick the move the numbers support, not the one that feels easiest in the driveway.
►Can an insurance company replace only half a roof?
An approval can cover less than the whole roof. Whether a particular approval is correct depends on the policy, the documented damage, and your state. This post treats the approval as a given and asks what you do with it.
►What can I tell a homeowner about what insurance has to cover?
Rules on what a contractor may say or do on a claim vary by state. Check yours before you advise on coverage. Send her to her policy and her carrier for coverage questions, and keep your side of the conversation on your scope, your price, and your schedule.
►Should I put a partial approval job on the calendar before she decides?
Only if you can rebook the day. A held crew day costs you the crew-day number if it goes unsold. In the example crew, that is $1,056 per day. Penciling a day is cheap. Holding it for weeks is not.
►What if she asks me to do the whole roof for the approved amount?
In the example, that is a $7,200 discount and a $1,680 loss on direct job cost. Run it the way you would run any discount: against the table above before you say yes.
The gap, your margin at full scope, and the cost of a held crew day decide a partial approval, and an empty calendar is when you follow them least. The Search-to-Booked Roofing System™ is built to put more booked estimates on your calendar, so a thin job is a decision you can walk away from, not a job you need.
