Highlights
“Oliver Blake and his team provided excellent, professional service during what was a very stressful roofing issue. Pricing was fair and transparent, and the work was completed promptly despite very wet weather. Jake and Jack were polite, hardworking, and clearly explained what was needed and why. The workmanship was thorough, everything was left clean and tidy, and the 10-year guarantee was reassuring. Nicky in the office was also helpful and responsive. A reliable and professional company I’d happily recommend.”
“Blakes Roofing undertook a complete flat roof replacement with a well organised service, photos, great communication and a prompt reply to queries so often missing with contractors. Can,t recommend them highly enough.”
“Oliver came to visit and advised me to repair the roof, unlike others who suggested getting a new one. The quote was clear, with a detailed description and competitive pricing. They carried out some lead work, replaced missing tiles, and fixed a gutter joint that was leaking into my bedroom wall. The work was done efficiently, and the site was left tidy. Nicky was good to work with, keeping me informed of any changes and arranging the job smoothly. Although I had to wait a while for the job to be done, I'd say it was worth the wait. The service matched my expectations based on the Google revie”

Roofing isn't licensed, so anyone can set up - and it's a trade with more than its share of cowboys. A big re-roof must meet building regulations; CompetentRoofer (the Government-authorised NFRC scheme) registers roofers who can self-certify that, and vets and inspects them at least twice a year. Check they're on it before you hire.
Check the CompetentRoofer registerNever 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.
