Most homeowners file exactly one roof claim in their life, if they're unlucky enough to need one at all. So it makes sense that nobody knows how this actually works. Here's the whole process, start to finish, the way I'd explain it if you were standing in my driveway asking.
Step 1: Something happens to your roof.
Usually hail or wind. You might notice it right away, or you might not notice anything until a roofer knocks on your door or you see neighbors getting work done.
Step 2: You file a claim.
You call your insurance company, they open a claim, and they schedule an adjuster to come look at the damage.
Step 3: The adjuster inspects.
This is the part most homeowners don't realize matters so much. The adjuster's job is to document what they see and write an estimate based on it. Adjusters see a lot of roofs in a short amount of time, especially after a bad storm, so their first look isn't always the full picture. That's not because they're trying to shortchange you. It's because a thorough inspection takes real time, and they often don't have it.
Step 4: The estimate comes back.
This is where most people assume the number is final. It isn't. The first estimate is a starting point, built off what the adjuster could see and document during their visit.
Step 5: This is where a good contractor earns their fee.
A roofer who actually knows what they're doing will do their own thorough inspection, documenting everything the adjuster's estimate missed — hidden decking damage, code-required upgrades, damaged gutters and vents and siding that are part of the same claim but easy to overlook. If there's a gap between what the adjuster found and what's actually there, this is called a supplement, and it's a normal, legitimate part of the process, not a red flag.
Step 6: The insurance company reviews and approves.
Once the supplement is submitted with proper documentation (photos, measurements, code references), the carrier reviews it and typically approves some or all of the additional items.
Step 7: The work gets done, and it gets documented too.
A good roofer photographs the whole job, before, during, and after, because a lot of what gets found and fixed can't be proven once the new roof is on.
Step 8: Depreciation gets released.
Most policies hold back a portion of the payout (depreciation) until the work is actually completed and documented. Once your contractor submits proof of completion, that final payment gets released.
The one thing worth remembering
The number on your first estimate is not the number your roof is worth. It's a starting point. The difference between that first number and the real number almost always comes down to documentation, someone taking the time to prove what's actually there. That's the whole reason a good inspection matters more than people think.
