Flat Roof Repairs in Slough & the Thames Valley

Flat roofs in the Slough area often face issues because of the way they were originally built. Older mineral felt roofs tend to go brittle after years of exposure to the sun. You might notice blistering, cracking around the edges, or water pooling in the centre because the "fall" of the roof isn't quite right. If you see damp patches on your ceiling or hear dripping during a Thames Valley downpour, it’s time to act. We don't just slap a patch over the top; we check the decking underneath to make sure the structure is sound before we carry out any flat roof repairs Slough residents can depend on.

If your roof is only leaking in one specific spot due to a puncture or a failed bit of flashing, a repair is often perfectly fine. However, if the surface is covered in "alligator" cracks, the seams are lifting everywhere, or the felt is pulling away from the edges, it usually means the material has reached the end of its life. We can take a look and tell you honestly whether a repair is a sensible long-term fix or if you are just throwing good money after bad.

EPDM is a flexible rubber membrane that is great for most domestic roofs because it handles building movement well and is very cost-effective. GRP fibreglass is a hard, rigid surface that is much tougher against foot traffic and has a very long lifespan. GRP is often preferred for its sleek look on modern extensions, while EPDM is a brilliant all-rounder for garages and hidden flat roofs.

Yes. Pooling or "ponding" water is usually caused by a dip in the roof decking or because the roof wasn't built with enough of a slope (the fall). When we carry out a felt roof replacement or install a new system, we can often use "tapered" insulation or adjust the timber firrings to make sure the water runs off into the gutters instead of sitting in the middle of your roof.

Under Building Regulations Part L, if we are replacing more than 50% of your flat roof covering, you are generally required to upgrade the thermal insulation to meet modern standards. This is actually a great opportunity to make your home warmer and lower your heating bills, as flat-roofed extensions are often the coldest rooms in the house.

This is almost always a problem with the leadwork or the upstands. The point where the flat roof meets a vertical wall is a common weak spot. If the lead flashing has come loose or the mortar pointing has perished, water will run straight down the wall and behind the roofing membrane. We specialise in leadwork repairs to ensure these joins are completely watertight.

We are very used to working in busy residential areas and narrow village lanes like those in Datchet. We manage our own logistics and ensure we keep the site tidy. If skip permits or scaffolding licences are needed from Slough Borough Council or RBWM, we can help advise on the process to make sure the work goes ahead without a hitch.
