G. S. Roofing (London) Limited

I contacted GSR at the beginning of October and they visited within a couple of days. A written estimate followed shortly after which was agreed. Work started erecting scaffolding and subsequently remedial works were carried out to the brick stacks front and rear. Start to finish of all the work was two weeks. The quality of the work to the brickwork, lead flashing replacement and flaunching etc was of the highest standard. The guys cleaned up on completion and worked diligently even though the weather was poor. Having worked on building sites for over 40 years I recommend their work from start to finish.

Very impressed by the courtesy and professionalism of G S Roofing’s team. They were punctual, completed the work on time - and within the quote - and tidied up every day. A really great, reliable team.

A great experience with the GS Roofing Specialists from day one: they came to assess the state of the roof on the same day I first called them; they arrived early on the agreed starting date, and they completed all the work on the roof and chimney within their estimated time-frame. The renewed parts of the roof and chimney look really impressive, and all the leaks have been fixed. In addition, communication with their office and the workmen was excellent, and I can’t recommend them enough!

I have used this company on a number of occasions, most recently, to remove a very large rotten skylight and install another including internal reconfiguration. Previous works have involved longer projects including repointing, re-leading and working on the top of the roof for a period of time with scaffolding and hoardings. They are a great family run company, have a tight team, great communications from Stephanie on the front line, and Mark and Jack on estimates, lead in times and bookings and all will do their level best to fit with your timetable. This time, I had to put the work back and they were very accommodating and picked up quickly when I was ready to go ahead again, arranged scaffolding to be put in place only for the time needed to help me accommodate landscaper's skips. They put more on the job to make it was done as quickly as possible so the the scaffold could be taken down quickly to accommodate my other works. All the team have the same work ethic, they work very hard, it is of a high standard plus they can find solutions for the trickiest of things and keep within the estimate. They are considerate around the home ( inside and out and with neighbours) and tidy up well. They offer guarantees and honour them with no fuss. I have no hesitation in recommending this company to others (and do) and feel confident they will do a great job for me, on time, without fuss and on budget. You can't ask for more.

We needed some minor repairs doing to our flat roof in order to satisfy the requirements of our insurers. GS Roofing did a prompt review and report for us and then the repairs themselves within a couple of weeks of that. We valued the personal service which very much reflects the fact that they are a family run roofing company, and in fact we had used them in the past. They explained clearly what needed to be done and the outcome looks very neat and professional. The cost was perhaps more than I was expecting at the outset but I decided that 'you get what you pay for', and the service we subsequently received was exemplary and wholly reliable.

G S Roofing has just re -slated a complicated pitched roof in Welsh slates and also re -felted a flat roof for us. We were kept very well informed throughout and Mark even brought me a life -size partial mock up before we started of what the layers of the roof plus ventilation pieces would look like! The work was completed within the estimated time and to budget. The workmen were punctual, reliable very clean and tidy and easy to talk to about any queries we had. We have been highly impressed by them on all levels.

GS roofers did multiple repairs on our front back and flat roofs. They worked non stop for a week and did a great job.

We needed to renew the flat roof above our side extension and the one above our bay window. They kept us informed about the scheduling of the work, and were actually able to start early because of the good weather. Everything was done very efficiently. They erected the scaffolding and then just got on and did the work from the outside, and cleared away all the debris, leaving no mess at all. The photos show a great finish. Very satisfied.

I recently had the pleasure of working with G.S Roofing London Ltd for a bay roof replacement, and I couldn’t be more pleased with the outcome. From start to finish, their team displayed exceptional professionalism, craftsmanship, and a genuine dedication to quality. The crew arrived promptly each day, worked efficiently, and completed the project on time and within the agreed budget—no hidden costs or surprises. They were thorough and precise, paying close attention to every detail, and maintained a clean and organized worksite throughout. I also appreciated their care and respect for my property—there was no damage to the landscaping or surrounding areas. The new roof looks fantastic and has noticeably enhanced the home’s curb appeal. I highly recommend G.S Roofing to anyone in need of roofing services. Their reliability, skill, and clear communication set them apart. A five-star experience from beginning to end!

Flashing was replaced, moss was removed and gutters were cleared. They were punctual, polite, friendly and tidy workers. The work was explained and photos were taken to show the completed work. On schedule and budget.

I had already received a couple of quotes to overhaul my roof but was particularly impressed with G S Roofing, which I found on Trusted Traders and was reassured that it was not only a family run firm but had been in business for 50 years this year. Mark the Estimator arrived promptly explained what would need to be done and produced shortly after his visit a written detailed breakdown of the work to be carried out. As agreed, on 6th January Jack and his team arrived and put up the scaffolding at both the front and back of my property. Jack kept me fully informed of the work being undertaken each day and any additional work that was needed as the work progressed. The whole job took 5 days including installing and taking down the scaffolding. At the end of each day, any debris and rubbish from the works was removed. I am very pleased with the work that was carried out and have no hesitation in recommending G S Roofing

Having failed to interest 3 companies to undertake moss removal from the roof, it was reassuring to discover that GS Strank were willing to take on the job. (Not advertised on their internet link so did not come up in my initial search.) Moreover was even more reassuring to be told that the company favours local clients as we live very close by. Was told that the work would take 2 days and it was recommended for safety and easy access to the roof to put up scaffolding. They arrived on the dot (9am) and the work was finished (on the same day) by the time I got back around 3pm. Very efficient and no sign of any moss coming down in the very strong winds we have had since. Very happy customer.

I was very impressed from the first quotation visit as the job was properly discussed, the days that it could be done and how long it would take, and access (as all had to come through the house). The works were done just as on the quote and very efficiently even though the weather was very bad; the workmen were very conscientious about leaving my home tidy at the end; Jack came to check the work as well. The scaffolding was taken down immediately after the works were completed. I was very pleased and all fitted around working from home days. I would definitely recommend them and use them again.

Work was carried out promptly following my initial approach and completed within 3 days as planned and within the sum quoted. I am completely satisfied with the outcome. All the staff were helpful and informative, explaining exactly what was entailed. A very pleasant company indeed.

I have used GS roofing for a number of years and have always found them to be excellent. This was no exception. Very efficient, reliable and thorough ,with fair and transparent pricing. They made the whole experience stress free and are great to deal with .I wouldn't hesitate to recommend them

Our first experience of GS Roofing was in the late 1980s when they replaced a roof for us on the house we lived in then. When we sold the house the buyer's surveyor commented on the quality of the new roof. They have continued to do a variety of roofing and guttering work for us ever since, most recently, this week, sorting out a blocked gutter. They are reliable, thoughtful and very good at their job.

Buyer's survey revealed two broken slates on my roof. Called two local firms that were recommended. G.S. Roofing, visited and quoted within a couple of days, did the job 4 days later. 20% cheaper than the other company. When I called their office to ask questions, the roofer I spoke to was very polite. The roofers that did the repair were tidy and polite. I asked for photos before & after the repair (for the buyers solicitor) and had them 1hr after the repair. Very happy with the service end to end, will use again and recommend them.

I had used G S Roofing's services several times over a number of years, while living in a detached house, with positive results. So, in late 2023, having moved to a building comprising four flats, the flat roof of which was coming to the end of its serviceable life, our residents' association took my recommendation to award the (not insubstantial) contract to GSR. The work took 6-weeks and was completed within the predicted time, and exactly as agreed. Any additional works which the foreman, Jack, considered necessary were immediately brought to our attention, estimated for, and adopted. Throughout the period they were with us, Jack and his team, guided by Mark, a highly experienced roofing expert, constantly kept us in the picture, were on time every day and were a joy to have around. They kept the entire working site, including our car park, clean and tidy throughout. I have no hesitation in recommending this well-managed, family-owned company, which has almost fifty-years expertise behind it. Many thanks for a great job.

Having narrowly survived a rogue trader, we approached GS Roofing for a quote and we're reassured owing to their far more professional approach. We had our roof completely replaced along with some extra work, and are very pleased with the results. The entire project was expertly handled and highly efficient, and will certainly recommend GS to anyone who'll listen.

GS Roofing did everything they said on the tin. Their work was done on time and on budget. They were a pleasure to deal with and i would recommend them without hesitation

I found GS Roofing through the National Federation of Roofing Contractors. After contacting several companies who were not interested in fixing a leaking glass roof on a house extension I was delighted to speak to Stephanie Strank who sent a surveyor to assess the job within three days of my call. An estimate followed two days later and a date (4 September) was confirmed to carry out the work. The two roofers who turned up on the due date were efficient and pleasant and the job was completed the same day. The work was done to the agreed schedule and budget. I cannot speak too highly of GS Roofing. They will be my first port of call if I ever have another roofing problem.

GS Roofing are a well-known, long-established family-run business in the Wimbledon area where I've lived for 30+ years. Their vans and lorries are a familiar sight on local roads. I had damp coming into a top-floor bedroom around the chimney breast. As I have a 3-storey Victorian townhouse, I wanted someone I could trust to do a proper and thorough job the first time around to avoid the inconvenience and risk of expensive scaffolding going up again later to fix remedial issues. GS Roofing were a natural choice to replace the old flat roof, as well as installing bigger front guttering, replacing decorative bargeboards and other smaller jobs. They did a superb, really neat job to a high standard that I am very happy with. They turned up when they said they would, were polite, respectful and tidy and kept me updated on progress and timelines. It was a pleasure to have them work on the house.

GS Roofing - recommendation by a neighbour - to identify the cause of water ingress of a 3 storey house. Mark, the surveyor visited quickly after my enquiry, able to identify the possible cause and repair to be carried out with a quote. This was provided in writing and Mark was happy to answer my questions which made me feel comfortable that GS Roofing was the right company to undertake the repair. GS Roofing also provided a 3 year guarantee. The workmen - scaffolders and roofers - work for GS Roofing which is great because I only had to deal with Mark to organise times for scaffolding and repairs. They took photographs of the before and after so I could send to my Insurers to determine if any of the repair was covered by insurance. The workmen were polite and professional. They arrived on time, did the repair in a day. There is no external rear access - had to come in the house to access the rear - they were careful and tidy. I was comfortable giving them keys whilst I continued with my work. Good recommendation.

I had huge confidence in GS Roofing to remedy a leak coming from a shared chimney stack which had entered our kitchen ceiling. The rain earlier this year was relentless, and I was told by Stephanie from the office that there were a lot of inquiries from callers who were asking for emergency call outs. Despite this, she kindly arranged an early visit. Two levels of the chimney stack were both repaired and new lead flashing replaced. There were some other repairs that were made on the flat roof which were also remedied. I am very satisfied with all these repairs and would be very happy to recommend GS Roofing. A lovely family-run business with professional, highly skilled roofing experts.

I found GS Roofing (London) Ltd. through Which? Trusted Traders. The initial survey was carried out by Gordon Strank, the firm's Director, and I received a written estimate for the works to be done shortly thereafter. After comparing and weighing up prices and reviews against those of other roofers, I accepted their estimate to rebed the gables at the front of my house, replace broken and missing tiles, and repoint all the ridge tiles. The firm has it's own scaffolding and so they were able to erect, and then after completion of the work, dismantle and remove the scaffolding quickly. The roofers were quick and thorough. I am very happy with the finished result - they all took pride in their work, and were helpful and professional and a pleasure to do business with. I noted that the firm's Director, Gordon Strank, kept an overview of the works, with an eye for detail. The firm is insured and is particular about the safety of it's staff, which I applaud. My roof and gables are now wind and watertight and the area has been left clean and tidy. I am very satisfied with their work and would have no hesitation in recommending this firm.
