1. NFRC Registration
The National Federation of Roofing Contractors sets quality and safety standards. An NFRC-registered roofer has been vetted and audited. Ask for the registration number and verify it online.
2. Public Liability Insurance
Minimum £2m, ideally £5m. Ask to see the certificate — not just a verbal assurance. Any roofer working at height on your property must be insured.
3. Written Quote After Survey
A quote given over the phone without seeing your roof is worthless. A proper roofer will survey in person, identify the specific issue, and provide a written quote with material specifications.
4. Local Knowledge
In Godalming, this means understanding the difference between clay peg tiles and concrete interlocking, knowing when lime mortar is required instead of cement, and being familiar with Conservation Area restrictions. Ask what they know about roofing in your specific area.
5–10. Guarantees, References, Payment Terms and More
Insist on a written workmanship guarantee (minimum 5 years, ideally 10). Ask for references from recent local jobs. Never pay the full amount upfront — a deposit of 10–20% is normal, with the balance on completion. Check online reviews but weigh them against the detail of the work described. Confirm the roofer will handle waste removal and leave the site clean. Finally, ask about their experience with your specific roof type — period properties, flat roofs and specialist materials all require different skills.
