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: 0800 046 3484 - Website: https://www.dnroofingandbuildingltd.co.uk/ --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/dn-roofing-building-ltd-2 Real public evidence only: every figure traces to a named source and is cross-checked.
