Trusted Traders - Monday–Friday: 7:30am–4:30pm ## 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. ## Contact - Phone: 07727 745970 - Website: https://harrowroofingandbuilding.com/ --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/harrow-roofing-and-building-limited-2 Real public evidence only: every figure traces to a named source, and reviews are cross-checked across 3 review sources.
