Key Takeaways
Roofing supplement companies, in-house work or software? What each option involves, how pricing models differ, and the questions to ask before you choose.
Preparing a supplement? Use the free checklist so nothing is missing when you submit.
The short answer
You have three realistic ways to handle roofing supplements: do them by hand in-house, use software to speed up the in-house work, or hire a supplement company to do it for you. The right choice depends on your volume, your office capacity, how much control you want and how a company would be paid.
There is no single best answer. A small crew handling a few claims a month may do fine by hand. A busy company may value outsourcing. Software sits between them. This guide compares them neutrally so you can decide.
The three options at a glance
The table summarizes how the options differ. It describes common patterns, not any specific company, because pricing and service vary widely. Always check a provider's own terms.
The key trade-off is control against effort. The more of the work you keep, the more control you have over the package and the relationship with the adjuster, and the more time it takes. Outsourcing saves time but shares control.
| Feature | In-house, by hand | In-house with software | Outsourced company |
|---|---|---|---|
| Who writes the supplement | Your office | Your office, with a drafting tool | The company's staff |
| Typical cost model | Staff time | Software subscription plus staff time | Varies: per supplement or a share of what is recovered |
| Control over the file | Full | Full | Shared |
| Learning curve | Builds with experience | Short, mostly the workflow | Minimal for you |
| Best when | Low volume | Steady volume and a small team | High volume or little office capacity |
What a supplement company typically does
Supplement companies generally review your photos, notes and the adjuster's estimate, identify items that may be missing and prepare a supplement package. Some also handle follow-up communication.
How they charge varies. Some charge per supplement, some take a percentage of what is recovered and others use a flat fee. Because models differ, compare total cost on your own claims, not the headline rate. Also consider that a percentage model means the company's income rises with the amount recovered, so ask how they decide what is worth including.
Check the rules in your state
Who may communicate with insurers about a claim, and under what license, varies by state. Confirm that any outside service operates within your state's rules.
Questions to ask before you outsource
Use the same list with every company you consider. Get answers in writing, and read the contract before you sign.
Pay particular attention to who communicates with the insurer and what your state allows. Rules about who may negotiate a claim, and what licenses are required, differ across states. If a company says it does everything for you, make sure that is permitted where you work.
Ask how they are paid
Get the fee structure in writing: per supplement, a percentage or a flat fee.
Ask who talks to the adjuster
Understand who communicates with the carrier and what rules apply in your state.
Ask for a sample package
Review what they would actually send, with photos and narrative.
Ask for references
Speak with contractors who have used them, and check reviews independently.
When in-house with software makes sense
Doing it in-house with software suits companies that want to keep control and speed up the writing. The software handles capture, organization and report building. Your team still reviews every finding and decides what goes out.
Compare it honestly against the other two options: what does a month of software cost against your staff time, and against a company's fees on your actual claims? Supplement Snap is one tool built for that in-house workflow. See software vs. spreadsheets for the by-hand comparison, and the sample report for the output.
How to decide
Run the numbers on your last ten claims. How much time did each supplement take, what did it cost in staff hours and what would a company's fee have been? Then consider control and risk: how comfortable are you with someone else representing your documentation?
If you are unsure, start small. Try one option on a handful of claims and compare the results. No option can guarantee approval, because coverage depends on the claim, the policy and the carrier.
Frequently asked questions
What does a roofing supplement company do?
It reviews your documentation and the adjuster's estimate, identifies items that may be missing and prepares a supplement package. Services and fees vary by company.
How much do roofing supplement companies charge?
It varies. Some charge per supplement, some take a percentage of what is recovered and some use a flat fee. Compare the total cost on your own claims.
Is it better to do supplements in-house?
It depends on your volume, office capacity and how much control you want. Low volume often works by hand, while software helps steady volume and outsourcing helps when capacity is limited.
Is it legal for a supplement company to talk to my insurer?
Rules vary by state. In many places, negotiating a claim for someone requires a specific license. Confirm what is allowed where you work.
Will any option guarantee supplements are approved?
No. Approval depends on the claim, the policy and the carrier, not on who prepares the package.
