Key Takeaways
How much do roofing supplements actually pay? Real revenue data from contractors on average supplement values, what gets approved, and how to maximize recovery.
The short answer: $1,500–$3,200 per job
On a typical residential roof replacement with an insurance claim value of $10,000–$15,000, the average supplement recovery is $1,500–$3,200. This represents hidden damage found during tear-off that wasn't included in the original adjuster estimate.
Some jobs yield more, some less. A simple re-roof on a ranch-style home might only produce $800–$1,200 in supplementable items. A complex roof with multiple penetrations, valleys, and older construction can produce $4,000–$6,000 in supplements.
What items contribute to supplement value
The most valuable supplement items by average recovery:
Decking replacement (3+ sheets): $200–$600. This is the most common supplement item.
Step and counter flashing (chimney or wall): $300–$800. Often corroded and hidden.
Ice and water shield (valleys + eaves): $200–$500. Code-required, often missing on older roofs.
Multiple layer removal: $400–$1,000. Only discovered during tear-off.
Pipe boot replacement (multiple): $85–$340. Cracked boots are extremely common.
Drip edge (full perimeter): $150–$400. Missing on many older homes.
On a single job, a crew might find 3–5 of these items, pushing the total supplement value into the $1,500–$3,200 range.

How many jobs have supplementable damage?
Experienced restoration contractors report that 70–90% of insurance tear-offs have at least one supplementable finding. The damage is almost always there. The question is whether your crew documents it.
The problem isn't finding the damage. The problem is that most crews don't have a system to capture it properly in the moment. By the time someone in the office tries to write up the supplement from memory and a few blurry photos, the opportunity is lost.
The math: what supplements mean for your business
Let's say your company does 10 insurance roof replacements per month:
Without supplements: 10 jobs × $12,000 average = $120,000/month
With supplements ($2,400 avg): 10 jobs × $14,400 average = $144,000/month
Additional annual revenue: $288,000
That's $288,000 in revenue that was already there, on jobs you were already doing. You're not finding new customers. You're just capturing the money that was hiding under the shingles.
Even a solo crew doing 4 jobs per month recovers an additional $115,200/year with proper supplement documentation.

Why most contractors leave this money on the table
The gap between 'finding damage' and 'recovering supplement money' is documentation. Most contractors fall into one of these traps:
Crew finds damage but doesn't photograph it properly
Photos get lost in text messages between crew and office
Office doesn't have time to write up supplements for every job
Supplement gets submitted weeks later with weak documentation
Adjuster denies it due to insufficient evidence
The solution is capturing documentation at the point of discovery, on the roof, during tear-off, in real time. That's exactly what Supplement Snap was built for.
How to start recovering supplements today
You don't need to change your entire workflow. Start with your next tear-off:
When your crew finds hidden damage, have them photograph it and tag what it is
Add a quick voice note describing the damage
Generate an AI supplement narrative from the field data
Email a PDF report to the adjuster before you leave the job site
Supplement Snap handles all four steps. The platform starts at $99/month with a 14-day free trial and pays for itself on the first job with a single approved supplement.
