Splits, blisters, ponding water and leaks round the edges. Shane repairs the patch that has failed when the rest of the roof is sound, and tells you straight when it is not. A Woking customer had a long-term damp problem resolved in 24 hours.
See flat roof repairsThree layers of felt, torched on over new 18mm OSB, with a drip edge and the system carried over parapet walls and coping. The Bagshot roof and the 110 square metre roof with a pitched conversion are both torch-on, with a 15-year guarantee.
See torch-on felt flat roofsA one-piece fibreglass roof with no joints, laid over new OSB. The Pirbright parapet roof was stripped, boarded and finished in Cure It GRP.
See gRP fibreglass roofingA single sheet of EPDM rubber bonded to the deck, with no joints in the middle of the roof. Rubber roofs are on Shane's list of services and suit dormers, extensions and garages.
See ePDM rubber roofingShane's Checkatrade profile lists liquid and single ply flat roofing too. Ask him which system suits your roof when he comes out.
The old covering comes off and the deck is checked. Soft or rotten boards are replaced with new 18mm OSB. Then the system goes on, with the edges, upstands and drip details done properly, because that is where flat roofs fail.
On a 110 square metre roof in February 2026 he added a pitched conversion so rainwater runs off instead of puddling, and finished it in two days with a 3-layer torch-on system and a 15-year guarantee.
BagshotBagshot, Pirbright, Egham, Farnborough and Walton-on-Thames all appear in Shane's flat roof jobs, from parapet roofs to garages and a new flat roof system on a house a Farnborough customer had just bought.
Each one has a job. 3-layer torch-on felt is tough, copes with foot traffic for maintenance and carries Shane's 15-year guarantee. GRP fibreglass cures into one joint-free skin, which suits parapet roofs and walkable areas: the Pirbright parapet roof was finished in Cure It GRP. EPDM rubber goes down as a single sheet with no joints in the middle, which suits dormers, extensions and garages.
Shane recommends one for your roof when he has seen the deck and the edges, and prices the alternatives so you can compare.
As long as the deck under it and the detailing at its edges. A flat roof fails early when it is laid on soft boards or without enough fall, so water sits on it. Shane replaces soft decking with new 18mm OSB, corrects the falls and dresses the upstands and drip edges properly, and his 3-layer torch-on flat roofs carry a 15-year guarantee, as stated in his posts.

Flat roof 5*
Shane and his team were brilliant from start to finish, Had severe leaks in my roof after buying a new property the guys put me at ease and went through everything thoroughly with me. New flat roof system installed Work is top tier and would definitely recommend
McDermott home improvements/ Shane and his team came out after completing work to my neighbours I got a quote at first and match against others but they were the most reasonable so got the work carried out I needed a new flat roof for my extension they completed the job on time and with no complications and all within budget. Shane and his team were very polite and respectful and did a great job would highly recommend to anyone looking to have any roofing work that needs doing. You won’t be disappointed.
New flat roof
Shane and his team were very professional throughout the job was always happy to answer and queries that had. Completed a fantastic job at a very reasonable price. I would definitely recommend McDermott Home Improvements to any person looking for work to be carried out.
A garage or extension is often one or two days. The 110 square metre roof in Shane's February 2026 post took two days.
The deck has sagged or was laid without enough fall. Shane corrects the falls when he rebuilds it; on the 110 square metre roof he added a pitched conversion to stop the puddling.
Every job is guaranteed, and 3-layer torch-on flat roofs carry a 15-year guarantee, as stated in Shane's posts.
Shane checks the deck, tells you whether it is a repair or a new roof and gives you a fixed price.
