The short answer
Supplements stall for many reasons, and some of them are outside your control. The ones inside your control are mostly about completeness and clarity. These nine mistakes come up often in the documentation advice we have written, and avoiding them makes a request easier to review. None of this guarantees payment, because the carrier decides.
Disclosure: we make Supplement Snap, which helps roofing crews document damage found at tear-off and export a report. It does not decide coverage, negotiate claims or guarantee approval. This page is general guidance, not legal or claims advice.

No email or sign-up needed. General guidance, not legal advice. Adjust it to your carrier's, client's and state's requirements.
1. Leaving off the claim number
Without it, the package can be misfiled or need a call to match. Put the claim number on the first page, in the file name and in the subject line.
| Feature | The fix |
|---|---|
| No claim number on the package | Put it on the cover page and in the email subject |
| Photos with no location | Number them and match each to a finding |
| Guessed quantities | Measure, and show the arithmetic |
| Everything in one email | Send one organized PDF with a short cover note |
| No follow-up date | Write the date when you send |
Fix the paperwork problems before they cost you.
Supplement Snap helps your crew capture locations, quantities and photos together so each finding is complete. Your first project is free.
2. Photos without locations
A photo of rotted wood means little if the reviewer cannot tell where it is. Number photos, tie them to findings and say which slope or area.
3. Guessing at quantities
About ten sheets is easy to dispute. Measure, count and show the math, such as 12 ft x 8 ft = 96 sq ft.
Most delays are paperwork
Reviewers handle many files. A package that is complete and easy to check is easier to act on than one that needs questions answered first.
4. Mixing opinions with facts
Say what you found and where. Avoid blaming the adjuster or guessing at causes you cannot prove.
5. Sending a pile instead of a package
Twenty loose photos in a long email are hard to review. One PDF with a cover page, a findings list and photos beside each finding is easier.
6. Waiting too long
Hidden damage is only visible during tear-off. Document it that day and send the package promptly. Check the claim for any time limits.
7. No follow-up plan
Write a follow-up date when you send, and record each contact. See the follow-up log guide for wording.
8. Skipping the code or policy source
If your request depends on a code requirement, attach where it comes from. Policy wording, state rules and carrier practice vary, so confirm the details for your job.
9. Not keeping copies
Keep what you sent, when, and to whom. If a request is questioned, your records matter.
A before-and-after example (fictional)
Before: an email with the subject Roof photos, no claim number, fourteen attachments named IMG_2031 to IMG_2044, and a body that says found rot, please pay.
After: a subject of Supplement request, Claim 123-456, 9 Pine Ct. A short body that says 3 findings, $2,140 requested, one PDF attached, follow up on Oct 17. The PDF has a cover page, a findings list and photos beside each finding.
The second version is easier to review. It does not guarantee payment, but it removes avoidable reasons for delay.
The checklist to run before you hit send
Is the claim number on the first page and in the subject? Does each finding have a location, a quantity and photo numbers? Are the quantities measured with the arithmetic shown? Is everything in one PDF? Does the email say what you want? Have you written the follow-up date? Five minutes with this list catches most of the problems above.
When a mistake has already happened
If you sent an incomplete package, send a short correction in the same thread: what was missing, the corrected attachment and a note that it replaces the earlier one. Do not send several partial versions. Keep a note of what you sent and when.
Frequently asked questions
Why do supplements get delayed?
Common reasons include missing claim details, unclear photos, estimated quantities and no follow-up. Carrier review time also varies.
Do these steps guarantee approval?

Promptly after documenting the findings. Also check the claim for any deadlines.
What should the email say?
A short note with the claim number, the number of findings, the total requested and what is attached.
What if the carrier denies it?
Read the reason, add missing documentation and consider a reinspection request or other steps.
Do I need the free templates to avoid these mistakes?
No, but they help. The supplement template and the tracker put the key fields on the page so nothing is forgotten.
