Roofing is priced per square (100 sq ft), so the number of squares and the line items for tear-off, underlayment and flashing decide the price. GenuineRate checks your estimate against typical installed prices per square in your metro and flags vague allowances.
Every line is compared with typical installed prices for your metro. You get what's high, what's missing, questions to ask, and a polite message to send.
Common overcharges
Too many squares
Measure-ups vary, but a quote far above your roof's real size inflates every per-square line. Ask for the measurement report (many roofers use satellite measurements).
Decking replacement “as needed” at a high rate
Rotten plywood is common, but the per-sheet price should be in writing before work starts, not a blank check.
Shingles not specified
Architectural shingles from different product lines vary in price and warranty. The estimate should name the brand and line.
Underlayment and ice shield left vague
Synthetic underlayment, ice-and-water shield and drip edge should be listed, especially in snowy climates.
Storm-chaser pressure
Door-to-door crews after storms may push you to sign quickly or hand over insurance checks. Check the license and local address first.
An asphalt shingle roof replacement, including tear-off, typically costs $400–$900 per square (100 sq ft). A typical 2,000 sq ft roof is about 20–24 squares.
Is a roof repair or a replacement better?
Small leaks and damaged sections can often be repaired for $400–$1,500. If the shingles are near the end of their life (around 20+ years for asphalt) or damage is widespread, replacement usually makes more sense.
What should a roofing estimate include?
Number of squares, tear-off and disposal, shingle brand and line, underlayment, ice-and-water shield, drip edge, flashing, ventilation, the price for any decking replacement per sheet, permit, and warranty terms.
