The key distinction: Hover captures what's on the roof. Supplement Tool writes the letter arguing for what the adjuster missed. Many roofing contractors use both tools together.

They solve different problems. Hover captures 3D measurements and photos of a property. Supplement Tool takes your existing estimate and writes a professional letter arguing for the line items the adjuster missed. Many roofing contractors use both: Hover for documentation and Supplement Tool for the letter.
No. Supplement Tool works from your existing estimate. You enter the damage details, the parts or materials needed, and the adjuster's response — and the tool writes the letter. No measurement capture required.
Hover typically costs $149–$299/month depending on the plan. Supplement Tool starts at $97/month with unlimited letters. If your primary need is writing supplement letters rather than capturing measurements, Supplement Tool is the more cost-effective choice.
Yes. Supplement Tool has a dedicated roofing vertical that covers starter strip, drip edge, ice and water shield, O&P, code upgrades, and the specific line items adjusters most commonly exclude from roofing claims.
