Specialist Roofing Services we have Carried Out

A Liquid Roofing Installation in London

Here one of our specialist roofers is applying AH25 Hydrostop to a flat roof on a commercial building in London. Once this liquid coating is applied the building will benefit from liquid reinforced waterproofing.

The benefits of using a liquid system on a commercial building such as the one in the video include:

• Ability to cope with complex detailing.

• Easy maintenance and repairs.

• Water Repellent upon Application.

• Cold Applied. No need for a flame.

• Can be applied all year round all the way down to one degree.

• Excellent Elasticity and Tensile Strength.

Client Testimonials

Warren did a great job. He was very careful, considerate and went to great lengths to make sure the job was done properly. I would not hesitate to use this company again.

Customer in Ingatestone

Highly recommended, not only for the service as my roof looks lovely!! But if you are in need of advice and are looking for an honest and friendly service Ryan goes above and beyond.

Angie Roberts, Brentwood, Essex

Ryan and team arrived, late afternoon, as agreed, to review balcony, approx. 25m2, 3 sides fed by tiled roof and one long length hand-rail. Problem, 3 leaks in different places from 10yr old asphalt roof. We discussed the problem and Ryan suggested a choice of two plan of action. We found his quotation very acceptable. This work was completed as agreed, in only a few days, to our complete satisfaction. Eight months after completion, I can now report that after a very wet winter, the roof is in a sound state. An excellent job done.

Customer in Cambridge

RJ Evans Flat Roofing Ltd I found by accident on the Internet. It was a video about asphalting steps. I called Ryan who was very professional and had a great deal of experience and knowledge. The job was booked in straightaway and a team set about taking off old asphalt rebuilding and repairing the big Victorian staircase and then asphalting. The finish was quite amazing, these guys are very skillful at what they do and My husband and I were delighted. They were a professional team really hard working and highly recommend them.

Customer in London

Having had huge problems with my neighbour who objected to any work being done on our party wall, Ryun personally went to speak to her putting her at ease and left everything so tidy after the job had been done. I’m very grateful, especially as this was a last minute request Ryun undertook despite being very busy. The workmanship looks very neat, and at last I have a happy neighbour.

Customer in London

All the other builders I’d called said they were busy until January! Ryun returned my call, visited on a very wet day and gave me a quotation for the job even though he said he was busy and lucky for me, not too far away on another job. On a sunny Saturday Ryun returned with his colleague- they were on time and did the job in a matter of minutes! Even though I only needed one tile replacing, whilst on the roof Ryun checked the remaining tiles and gave advice regarding moss build-up. I will definitely recommend his services.
