Two roofing estimates can look hundreds of dollars apart and actually be priced identically — the difference is just what each one includes. If you only compare the bottom-line number, you can't really compare the bids. Here's how to read a roofing estimate like the contractor you're hiring.
What a complete scope includes
A thorough estimate should spell out, in writing:
- Tear-off and how many existing layers are being removed (and disposal)
- A decking allowance — what they charge per sheet if rotten wood is found
- Underlayment type (synthetic vs. felt)
- Ice-and-water shield in valleys and around penetrations
- Drip edge and flashing (and whether it's reused or replaced)
- The shingle brand, line, and color
- Ventilation — ridge vent or other intake/exhaust
- Valley method (open metal vs. woven/closed-cut)
- Cleanup and a magnetic nail sweep
- The workmanship warranty and the manufacturer warranty
- Whether a permit is included if required
Red flags to walk away from
- A verbal quote, or a one-line price with no scope
- A large deposit demanded up front before any work
- No proof of license and insurance (in Tennessee, ask — and verify)
- High-pressure, “today only” storm-chaser tactics
- A bid far below everyone else's (something got left out)
Questions that put you in control
“Is tear-off included?” “What's your decking rate per sheet?” “What underlayment and ventilation are you using?” “Who does the work — your crew or subs?” A contractor who answers these clearly and in writing is one you can trust.
