After a very bad experience previously with another contractor, Joe and his whole team were professional from the outset. The initial inspection and quote were discussed in detail with any areas of uncertainty clarified and capped. When the work got underway any uncovered issues were openly discussed, solution focused and fairly priced. Thoroughly recommended.

Gulley and slates were left in a poor state by a previous roofer. GWS gave me a comprehensive report on what needed doing, what was vital and what was not. The completed lead work on the gulley looks fantastic and all of the tiles have been reseated properly. All work was carried out to time and to budget. What a relief to find a good, honest roofer!

We used GWS to replace our front pitched roof and flashing. The quality of the work was good (the new roof looks great) and Gary was responsive to any questions/issues we had. Based on other quotes we obtained the price was also competitive. The work did take a a week or so longer than anticipated due to other jobs they had on - but in the event that didn't cause us any issues.

The job description was to recover a flat roof to specifications and to replace a rainwater pipe which required access to a neighbouring property and the use of scaffolding. We were happy with the way the work was completed and the ongoing communication with the team at GWS. There were problems to overcome such as the access to the neighbouring property needing good communication with the owners who lived away from the area. The Covid-19 crisis also caused a few problems, such as the supply of certain materials, but this resulted in limited delay and perfectly acceptable under the circumstances. Easy contact with the office management providing good lines of communication. Good attention to detail and work came within budget - a very satisfactory contract completed.

This was the first time I have used GWS Roofing after they were recommended to me. From initial quotation through to the finished job I have absolute praise for them. They were prompt, courteous and tidy, keeping me informed of their progress throughout the job. All the debris was collected and removed from my house and the work completed to the high standard I was expecting. I have no hesitation in recommending their quality workmanship.

GWS gave an honest assessment of the work that needed to be done on the dormer windows, and of the options open to me. I felt their quote was fair and they were efficient and reliable. They kept me advised of the timing and what work would be done when, and stuck to their schedule. They were also extremely pleasant to deal with, and very helpful generally. I felt this is a serious and thoroughly decent firm whom you can trust to do an honest and competent job.

Huge thanks to Joe and the team at GWS Roofing for doing an excellent job on the flat roof at one of our rental properties. His expertise was very useful and everyone was prompt, communicative and thoroughly professional from start to finish. It was really useful to receive the quote with options for what could be done versus what needs to be done and the costs involved. We are delighted with the results and recommend calling on GWS for any roofing issues!

I instructed GWS to quote for re-tiling and re-insulating the back pitch of the roof, including a dormer window, requiring some pitched roof, flat roof and lead cheek work. The estimator who came to inspect the roof to provide the quote showed patience and understanding in answering the many questions I had. The quote was presented in a clear and itemised manner and the company's insurance policy was attached. Whilst the initial quote presented was higher than others, GWS were willing to discuss it and I believe the price we finally agreed to reflected a fair price for the roof-work required. GWS' numerous industry accreditation gave me comfort that the company was reputable and would provide a good level of service. The on-site workers were prompt in starting the working day, professional, respectful and courteous throughout. Whilst the roof-work took a little longer than anticipated, it was thorough and of good quality. They ensured the skylight was clear of dirt and dust regularly and, upon completion, they left the roof and property in a clean state. I would recommend GWS for anyone wanting to instruct a reputable roofing company for good quality roof-work and I would certainly instruct GWS again in future. A few weeks after the roof job was completed the newly installed gutter began leaking. GWS sent a team round within a week of notice and repaired the leak. I was pleased with how professional and prompt they were in addressing the minor fault.

I have no hesitation in recommending GWS and the Sparrowhawk family as a very professional and pleasant firm to deal with. They carried out two separate pieces of work for me during the Covid-19 lock-down. The first to complete work to rectify lead work on the parapet wall beside my loft extension, which had already started before lock-down in March. The second - once lock-down restrictions had been eased - to replace the felt covering on the roof of my shed in the garden. Both jobs were carried out within budget - and within the time specified in their estimates. As a firm, they are very easy to deal with. No problem in reaching them on either the phone or by e-mail. Surveys and estimates are swiftly arranged and given and dates for work to be carried out are met.

Work on a 'London' roof with a valley gutter and parapets

The work involved capping parapets, installing a new valley gutter with a higher gradient, relaying the roof with new tiles and replacing joists where necessary. It was done to the agreed schedule and budget. GWS stood out in that their quote was clear and were very happy to visit and explain any items of work or technical terms. We liked the fact that their was more than one generation in the family business, we dealt with Daniel who supervised the work and Gary who would be there for Daniel to consult as needs be. We were confident they fully understood the issues associated with our roof. Throughout the job they were happy to send us photos and respond to our phone calls asking after progress. We were please with the behaviour of their employees during the job and were impressed with the dedication and care shown by the skilled roofer who must have done all the tricky bits that mean the roof isn't going to leak. There were a couple of contingent items, which were spelt out and quoted for in the quote, regarding the potential support of the gutter and that it may have to be relaid with a higher gradient. We were consulted on these items when the roof was first uncovered, and decisions could be made.

Just wanted to jump on here to say thank you so much to ‘GWS Roofing’ for the extremely efficient and satisfactory work they have just finished on our building. We seem to have had problem after problem with not only the roof but other roofing companies who have either let us down or not spotted other problems which have then led onto other issues. This has been going on for over a year so as you can imagine we were extremely happy when GWS said they could come out to price up the work and get started only the week after the job was looked at. We are based in London so thought there would be huge issues the minute the lockdown started, but GWS went above and beyond to stay in touch with me about how they were going to tackle the issues, by this point the scaffolding was already up but the work had barely even started, I was thrilled to find out they would carry on as normal to finish the job and were super careful and professional in regards to the PPI they used and precautions they took to keep their distance from us and each other. The work was finished before we knew it and couldn’t be happier. Thank you so so much! Will be recommending this company to anyone who needs any roof work and will be using them again if we ever need any help on our other buildings.

GWS have, yet again, saved the day. We returned from Christmas to find our guttering and drainpipes had failed resulting in two rooms being damaged by rain. GWS came and assessed the situation; within a couple of days they had erected a scaffolding tower and by the end of the week the problem was efficiently resolved, saving us from the next bout of heavy rain and high winds. Thank you very much GWS!

GWS replaced a section of gutter. We have used them three or four times before, including to re-slate the roof. The service overall is impeccable: friendly, straightforward, and approachable, with clear explanations about what the job entails, clarity about schedules, and an almost instant response to queries. As we have found in the past, the operatives on this job took a quiet, serious and efficient approach to the work, and were pleasant and friendly throughout. We strongly recommend GWS without reservation .

We had a real and difficult problem with our flat roof and collapsing wooden decking. Joe from GWS came round promptly, amongst other roofers, but he was definitely a cut above the rest. A stepped approach was identified that would deal with the immediate problem and then we could discuss the bigger requirements. Never felt under any pressure to agree anything and we moved seamlessly from addressing the initial problem quickly to working on the decking and maintenance of the main roof. Pricing was fair and all difficult matters were discussed and agreed up front with no additional costs for dealing with the unforeseen. Cannot recommend them too highly.

I first used GWS roofing in 2014 for work to the roof terrace at my old address. The work they carried out was excellent, within time specified, on budget. I was very pleased. Once again I have turned to them for roof-repairs to my new house. Once again they have turned up when they said they would, estimated clearly and transparently, commenced the work on the date specified and carried out excellent work. Throughout, they have been courteous, friendly and completely trustworthy. Because of this they have lots of work. So you may have to wait a while before they can start work. I think it is worth the wait.

The planned work was a change of the gutter pipe inside a narrow gutter box at the roof level. GWS Roofing made an initial quote for this work before opening the gutter box (which they could only do when starting the work). They discovered a quite deficient gutter once they opened the gutter box. They were very good at advising me that more work than initially expected was needed since the whole structuring of the gutter had to be replaced, to find the best way to sort the problem in a very narrow space within the gutter box and to let me know about the additional costs incurred by this unexpected work. The outcome was globally very satisfying. They moreover showed what the problem was so there is no doubt about the fact that the additional work was indeed needed. I am very stasified by the work done and the information flow and would stronlgy recommend this roofing company.
