Do you charge a percentage of the supplement?

No. Every file is a flat fee quoted before we start. A share of insurance proceeds can be treated as public adjusting in some states, and a flat fee keeps your margin on the job.

What do you need to write a supplement?

The carrier's estimate, photos of the damage and of anything the estimate leaves out, and a measurement report if you have one. Notes on what you found during tear-off help.

Do you talk to the adjuster for me?

We prepare everything the adjuster needs and answer technical questions on the estimate. Negotiating on behalf of the homeowner is for the homeowner, their public adjuster or their attorney.

For roofers and restoration contractors

Supplements Written and Followed Up

Send the carrier's estimate, your photos and measurements. We write the supplement in Xactimate® with the code or IICRC basis on every line, the proof the desk reviewer needs, and a cover letter, then follow it through to approval with you.
