I manage our own apartment block and our flat roof was in very bad repair and leaking into several of the flats. It needed replacing. I got several varied quotes for replacement and as costs were pretty high I recruited a chartered surveyor to oversee the quotes and recommend. Best thing I ever did. When I told the contractors there would be a surveyor involved, they disappeared. The surveyor then recommended GWS Roofing as they had dealt with them before. One thing of importance was they would guarantee the roof works for 20 years. They did a full analysis on the roof and recommended Langley Roof technology and they are approved fitters of this roofing product. The job took just over 2 months. They did an amazing job for me. There were weekly inspections by the surveyor and the roof suppliers with reports to me on progress. They were on site every morning and on time and worked every day until the job was complete. I could not fault their effort and enthusiasm throughout the construction. They invited me to observe the roof at regular intervals to see the progress. I was delighted with the result. I could not recommend them high enough. I have my guarantee too and that is something that not all roofing contractors will supply. Brilliant Job and company to deal with! I thoroughly recommend them. Paul - Director of Clark House Management Ltd.

We needed the entire roof of our house replaced. GWS offered a fair quote and honoured it. They were always on time, straight forward and pleasant to deal with. They did a great job replacing rotten wood beams, and supplying and fitting natural slate and lead to the roof. I am very happy with the end result

A trustworthy, honest and reactive company. GWS replaced the flat roof of our property, which turned out to be a more complicated job than anticipated. Despite a number of issues, the team were always efficient and reactive, with good communication throughout. This included helping coordinate other tradesman. The main reason we chose GWS, even at a more premium price, was due to the guarantee they offer - it is hugely reassuring knowing they would return to resolve any issues should they arise. They are an approachable and friendly team. Thanks to Gary, Joe and the team.

GWS replaced a mansard roof for me. Natural Spanish slate on all sides and a felt roof on top, plus new lead in multiple places. They did an excellent job and I was very pleased with the result. Joe was friendly and always helpful. I had Gary as site manager who was also always reachable and came back to me within a day whenever I had any concerns. The roofers I had on-site were all polite, friendly and worked tirelessly to get the job completed as quickly as possible. Mark and Alfred did an excellent job of slating the new roof. Rob replaced my flat roof and he also did a great job. I found GWS to be trustworthy and dependable roofers and would use them again.
