Highlights
“5 STAR PLUS They had a tricky job from the start with part of the garage not being level. Also at the end of the garage is an additional outbuilding added on with a reverse slope, using the same guttering. A daunting job but Corry listened to what I wanted to be done and he was here every morning to explain everything he was doing. The workmanship is first class, Corry was excellent and his team, Adam & Barry worked hard and did an excellent job too. I thoroughly recommend CLS, they exceeded my expectations.”
“very thorough and professional job ; repairs to chimneys, and two flat roofs plus guttering”
“Very friendly and helpful company Did a great job, nothing was too much trouble Would highly recommend”
Detailed reviews
We had a leaking roof and contacted CLS—Cory came out the very next day to assess the issue and provide a quote, clearly explaining the problem on the spot. The team arrived on time, were polite and considerate, and completed the work over two days to an excellent standard. They even worked through an unexpected heavy rain shower to ensure our roof was fully watertight. Cory kept us informed throughout, sending photos and videos before, during, and after the job, and also took the time to check the rest of the roof, truly going above and beyond. I wouldn’t hesitate to recommend CLS to anyone—absolutely brilliant service from start to finish.
Having had some work carried out by another company on the roof, we'd been advised that the roof felt would need replacing. I contacted Corry at CLS for a second opinion, he did a drone survey of the roof, look at pictures we'd taken from inside the loft and assured us that the roof was perfectly fine and no further action would be required. This put our minds at ease, I would have no hesitation on contacting CLS or recommending them for further work or investigation should we need them.
Changed a roof vent for kitchen hob extractor. Excellent, prompt and friendly service. Clearly explained what was needed and nothing was too much trouble. Have used them before and would not hesitate to use them again in future.

Corry and his team provided us with excellent service to repair our leaking roof valley. From the initial assessment of the problem through to completion every step was fully explained. The works were carried out professionally, always keeping areas neat and tidy, and the finished job looks great.
Chimney repairs
Corry and his team did an amazing job from start to finish. Corry initially came out after my enquiry about a few jobs I thought was needed. After using a drone Corry was very honest and concluded some of the jobs I thought needed doing were not needed, but the chimney was worse than expected. The scaffolders did an amazing job and were very polite and accommodating. The work took as long as estimated and to a very high standard. You can tell they take pride in their work. They tidied up after themselves every day. We would highly recommend Corry and his team for any roofing jobs.

CLS did a great job replacing a cement verge on my gabled roof due to failing undercloak and general wear and tear. After my initial enquiry Corry visited my property promptly and provided sound recommendations for repairing my roof and was upfront about the need for scaffolding and cost. The work was done to a high standard and CLS were very professional throughout. CLS were also able to work through an additional problem with my roof that was discovered during the work. I also valued the drone survey of my roof and subsequent recommendations that I can bear in mind for the future. Thanks!
Great team and prompt service. showed me progress video of the works on my roof which was great. Would use again as quality of workmanship spot on.
Corry and his team installed new fascias in our house some years ago and did a great job. Yesterday they popped back as a small piece had became loose. They quickly and efficiently repaired it and didnt even charge! You cant beat such a great service.

The job was assessed professionally and very honestly by Corry. There is no need to proceed right now. I was very impressed by his helpful approach.
Verified by CheckatradeFlat roof repair, plus fixing badly fitted facias and door
Corry and his team did an excellent job repairing a badly installed flat roof. They repaired the leaky roof, repositioned the facias and fixed a doorframe that hadn't been properly fitted. They were really helpful and provided regular updates. Highly recommended.

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.
