Roofing mistakes are expensive and hard to undo. These questions help you compare material specs, tear-off practices, warranties, and how the contractor behaves around insurance claims.
Why it matters: Roofing is high-injury work. Confirm licensing where required and that workers on your roof are insured — not day laborers with no coverage.
Why it matters: Overlays can hide deck damage and may violate manufacturer requirements for warranty. Tear-off costs more upfront but reveals rot and lets them start clean.
Why it matters: “Architectural shingles” is not a spec. Brand, product line, color, and warranty tier affect price and longevity. Lock them in writing.
Why it matters: Shingles get the attention; flashing and ventilation prevent leaks and heat damage. Cheap bids often skimp here.
Why it matters: Decking replacement is commonly priced per sheet. Know the unit price and approval process before the tear-off starts.
Why it matters: Manufacturer material warranties differ from contractor workmanship warranties. Ask what voids coverage (like improper ventilation) and whether warranties are transferable.
Why it matters: Many cities require roofing permits. Inspection protects you and documents that the job met code.
Why it matters: Be wary of contractors who appear unsolicited after storms, offer to “waive your deductible,” or push you to sign over claim rights. Understand who communicates with the insurer.
Why it matters: Nails in driveways and shredded shingles in gutters are common complaints. Ask about jobsite protection and a final magnetic sweep.
Why it matters: Large upfront deposits are a classic roofing scam pattern. Prefer staged payments tied to milestones, with final payment after completion and cleanup.
