Smart checks
Before you hire a roofer
Never agree to roof work from a cold-caller at your door or an unsolicited 'we noticed your roof' note — that is the classic roofing scam.
Get a written quote that itemises access (scaffolding or a tower), the exact materials, and the workmanship guarantee — not a vague day rate.
Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
