Frequently Asked Questions

Are these roofing tools really free?
Yes — every tool on this page is 100% free with no sign-up, no email required, and no hidden fees. ProvenQuote builds free tools to help homeowners make informed decisions before talking to a contractor.
How accurate is the roof replacement estimator?
The estimator provides a national baseline using 2025 contractor pricing data, accurate within 15–25% for most US markets. Local labor rates, material availability, and roof complexity can move your actual quote above or below this range. Use it to benchmark quotes — not as a final budget.
What is a roofing square?
A roofing square is 100 square feet of roof surface area. It is the standard unit used by contractors to price labor and materials. A 2,000 sq ft home typically has 20–25 squares of roof surface depending on pitch.
How do I know if I have insurance-eligible hail damage?
Key indicators include: confirmed hail event of 3/4 inch or larger at your address (verify via NOAA storm data), granule loss in gutters, dents on soft metals (vents, AC fins, gutters), and bruising or cracking on shingle surfaces. Use the Hail Damage Assessment tool to walk through the full adjuster checklist.
What is the difference between ACV and RCV insurance coverage?
ACV (Actual Cash Value) pays the depreciated value of your roof — what it was worth, not what replacement costs. RCV (Replacement Cost Value) pays the full replacement cost minus your deductible. On a 15-year-old roof, the difference can be $6,000–$10,000. Use the Insurance Claim Calculator to see both scenarios for your situation.
Are Class 4 impact-resistant shingles worth it?
In hail-prone markets (TX, CO, OK, KS, NE), yes for most homeowners. The upgrade costs $2,000–$5,000 more than standard architectural shingles, but insurance premium discounts of 15–25% often pay that back in 3–6 years. Use the Class 4 ROI Calculator to run your specific numbers.
How do I calculate roofing squares for my house?
Multiply your home footprint (length × width) by the roof pitch multiplier, then divide by 100. A 2,000 sq ft home with a 6/12 pitch has a multiplier of 1.118, giving approximately 22.4 squares. Add 10% for waste to get your order quantity. Use the Roofing Squares Calculator above to do this automatically.
Can I use these tools to verify a contractor's quote?
Yes — that is one of the primary use cases. The Roof Replacement Estimator gives you a national baseline to spot-check contractor pricing. The Roofing Squares Calculator helps you verify the square count a contractor is using. The Insurance Claim Calculator helps you understand whether an adjuster's payout offer is reasonable.
