## Before you hire a roofer
_What to check when choosing this kind of trade (general guidance, not a claim about this business):_
- 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.
- A major re-roof must meet building regulations. Prefer a roofer on the NFRC Competent Person Scheme (CompetentRoofer), who can self-certify the work and is vetted and inspected at least twice a year. Check they're listed at nfrccps.com before you commit.
- Ask to see a portfolio of completed work like yours, plus recent references you can contact.
