Start with the same measurements
Ask each contractor to identify the roof area, slope, existing layers, and roof sections included. A quote for the main house may exclude a porch, garage, or addition. Compare replacement scopes using the same measurements and product specifications.
Put the line items next to each other
Record tear-off, disposal, decking, underlayment, flashing, ventilation, installation, and cleanup for each bid. Mark an omitted item as a question rather than assuming another contractor overpriced it. Ask whether sales tax, fees, and optional upgrades are included where applicable.
Agree how hidden work gets priced
Request a unit price or pricing method for deck repairs and a procedure for documenting damage. Ask for photos and your approval before additional work. Record which tasks are allowances and which are firm parts of the bid.
Check approvals and warranty terms
Confirm permit requirements for the proposed work. Compare who applies and arranges inspections if needed. Read the installer and manufacturer warranties separately, including registration, exclusions, and transfer terms.
Use your bids as the evidence
This page does not report a verified survey of contractor quotes. Use the local quote worksheets to organize your own estimates and the cost guide to identify questions. If one recommendation differs from the others, ask for the condition evidence behind it.
Request a roofing referral. Availability and response times vary.
