Highlights
"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."
"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!"
"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.

Thank you John for installing a lovely dry verge for us.
John came around and re pointed the ridge tiles on top of my roof couldn’t recommend enough thanks John
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
Fantastic and professional work, would use again!
Class workmanship, used before & would use again.
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.
Used TrustATrader again and have for the past twenty years and as usual come up trumps. Had a problem with a birds nest in the eves and John of JTS Roofing and Guttering came, explained exactly what was wrong and what was needed to put it right. He was very punctual and did the work in a very professional manner. I would recommend him to anyone considering having roofing done for he is very knowledgeable in that field.
Came round and had seen the problem, Did a quick fix to help and didn’t charge. Seems very honest and didn’t try to upsell.
We found John to be very helpful and competent in carrying out a recent repair to our guttering and would have no hesitation in recommending.
John, Tom and his team was exceptional from start to finish with installing our flat roof. Thanks a lot guys
Although only a small leak repair, there was no fuss and it was fixed within some new felt and tiles within a few hours.
Very class work in 2024 replaced three roofs on my rental property’s. 2025 done some small damp repairs in the kitchen. 2026 Has replaced some guttering for me as always would recommend

Smart checks
Before you hire a roofer
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.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
