About
G.S Roofing is a family run business established in 1975 by the current owner and Managing Director Mr Gordon Strank. G.S Roofing as been operating from our current office and yard since 1985 and became a member of The National Federation of Roofing Contractors (NFRC) in 1988.
Having been based in Wimbledon for the past 30 years, many of our customers have been through recommendations, and there are few roads left in the area where our roofing work cannot be seen.
We are willing to take on work ranging from small repairs to complete new roofs; Flat, Tiled, or Slated, and to ensure piece of mind. (An insurance backed guarantee is also available for new roofs.)
We have a team of reliable and experienced employees who carry out all our work including scaffolding. Many have been with the company for a number of years.
Our office is open 8am to 5pm, Monday to Friday and our friendly staff will be happy to help with any enquiries, or to book a free 'no obligation' estimate.

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!

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.
