John, Tom and his team was exceptional from start to finish with installing our flat roof. Thanks a lot guys
John was helpful with doing the job, answering all my questions, (I had quite a few =) and sharing his output and knowledge of what I should do next.
I would not hesitate in recommending John to others. He was responsive and easy to deal with, efficient on the job, and helpful with his advice. Nice chap.

I had a new roof installed by John and I am very satisfied. The team was professional, efficient, and used high-quality materials. Communication was excellent, and the roof looks fantastic. Highly recommend! Thanks John
John came around and re pointed the ridge tiles on top of my roof couldn’t recommend enough thanks John
Thank you John for installing a lovely dry verge for us.
After a company had worked on our roof, failed to finish any snags. Contacted John, quote was cheaper than other ones received. John arrived at the appointed time, reattached our gutter, job done.
Fitted new gutter joints as requested. Great job for a great price. Would hire them again.
They replaced three roofs for us with incredible speed and precision. The team was professional, hardworking, and delivered top-quality workmanship. Each roof was completed on time and to a high standard, with no mess left behind. If you need reliable and efficient roofing services, this company is the company to call!

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.
