A roof is a system, and the installation quality matters as much as the product label. Prequalify contractors before you compare final totals.
Verify the business and coverage
Ask for business information, licensing where required, liability coverage and workers’ compensation information that applies through the project period.
Request a detailed written proposal
The proposal should identify roofing material, tear-off, underlayment, flashing, ventilation, cleanup, start and completion expectations, payment terms and warranty.
Check references and recent work
Ask for recent projects similar to yours and speak with customers about communication, cleanup, change orders and warranty follow-up.
Understand supervision and quality control
Ask who will oversee the crew, who your day-to-day contact is and how installation issues are documented.
Compare like for like
Use the Roof Replacement Cost Calculator for budget context and the quote comparison guide to align scope before choosing a contractor.
