Cornerstone Roofing Reviews 

Cornerstone provided a professional survey of our rather unusual shape garden room roof and came up with a quotation that seemed very reasonable for the work required which included removing 5x polycarbonate sheets on a sloping part of the roof, installing boarding and three layers of felt in their place plus re-felting a triangular flat portion of the roof to make a seamless felted roof. The gang arrived onsite ontime and worked really hard in the extreme heatwave. Plenty of tea and cold drinks supplied! The roof was completed ontime and looks very neat. I was particularly impressed with the 'above and beyond' attitude they applied to the job to make sure that it would provide good drainage in wet weather straight into the gutter. 25 year guarantee too!

Reliable and professional from start to finish, including the scaffolders. Very polite and left the site clean and tidy. I would certainly recommend.

Totally reliable and trustworthy company - excellent professional and knowledgeable service from start to finish.

Good communication with the office. The roofer came to look at the job when arranged and written quote was emailed soon after. The work was fitted in very quickly. The two roofers arrived on time, were pleasant, explained what they had done and left the site clean and tidy.

Adam and Harvey took great care to do an excellent job

Excellent service. Prompt, friendly and high quality.

Cornerstone did a great job finding the leak in our roof/dormer and fixed it swiftly, all in all a reliable, friendly team, great in keeping us updated with great customer service. Left the job clean and tidy, would recommend.

Fast and excellent work by friendly workers who cleaned up after they finished. Would highly recommend.

A very professional, hardworking team setting and meeting high standards. I felt very reassured that not only would the work be carried out to a high standard but that the work would be carried out expeditiously and in timely manner especially given the recent changeable weather.

I had two slates blown away on my roof and was provided with a quotation to replace these. On the day Tom checked the whole roof and actually replaced an additional three or four damaged tiles all for the price originally quoted. Very happy with the service and happy to recommend Cornerstone Roofing.

Two warm roof dormers installed. Ben and the team were great! Initially quote was reduced by £2k as they didn’t need to replace the boards! Fantastic service, very quick. Few snags were dealt with quickly. Highly recommend.

An outstanding experience with Cornerstone from start to finish. The work to my roof was completed as expected in the time frame expected with good communication throughout. The team on the job deserve special mention for superb customer service, nothing too much trouble, supremely helpful and courteous throughout. Everything left stick and span at the finish of the job. Thank you Lee and Will.
Who knew a new garage roof could bring so much joy. 😊

Finished the work while we were out. Left clean and tidy. Friendly service with good communications.

Fantastic from initial approach to completion of work. Ben was very helpful and provided us with an estimate, giving us a couple of options. Once we had made a decision we asked if we could book the work in asap whilst we still had some scaffolding up. Although very busy, Gary agreed to work over the bank holiday weekend and did a fantastic job, which we really appreciated. Ben, Gary and Margeret were all great and we wouldn't hesitate to use Cornerstone Roofing again or recommend them to others.

Ben was approachable and professional. The cornerstone team arrived early and completed the work to a high standard. Great communication throughout.

Hardworking. Tidy. Efficient. Difficult to know what they could have done better.

Amazing company, I recommend them to everyone! They have done a remarkable job and they did in less time than it was initially promised. I am honestly very pleased with their work.

The works on my roof required a specialised team and the installation of scaffolding.
I wasn't present when the works were carried out but I was kept fully up todate and the works were done in the time scale agreed.
Good job

As I rarely need roofing repairs I had to trust the reviews I read online, and there are many, but I chose Cornerstone based on that initially.
Having got a couple of quotes I chose Cornerstone as they were not only better value, but more professional in the way they explained the options during the initial visit, and in the written quote options. Communication by email and phone to Margaret was always easy and prompt.
I needed my ridge replacing together with a few hip tiles. Cornerstone actually rang to see if I could have the roofing done earlier than the allotted date, which suited me. They attended on time and did the work in one day, rather than the two set aside. The weather was freezing, but Adam and Henry did a professional job, and were very polite and helpful in explaining what they were doing. They even replaced a few broken tiles that they spotted whilst here. Afterwards they tidied up and left the place as they found it. I could not have asked for a better service. I would highly recommend Cornerstone and will undoubtedly use them again if needed in the future.

Ben and the team helped us out after Storm Darragh left us missing 5 hip tiles. Despite being booked up well into the new year, they squeezed us in and pulled out all the stops, organising the scaffolding and carried out the repair 3 days before Christmas.
