Flat Roofing London — Installation, Repairs & Replacement

Flat roofing solutions across London — installation, repairs and full replacement using durable, long-lasting waterproof systems. From extensions and dormers to garages and outbuildings, we deliver flat roofs built to last.

Flat roofs fail at the edges, not the middle. That's why we spend the time on trims, upstands and abutment detailing on every job — proper aprons against walls, neat edge trims with drip details, and falls that actually shed water rather than pool it.

We install modern flat roofing systems suited to your property and budget — single-ply EPDM rubber, GRP fibreglass and torch-on felt — all installed by our own roofers, with proper falls, insulation upgrades where needed, and quality flashings.

Whether it's a new flat roof on an extension, a replacement for a failed felt roof, or a repair after a leak, WM Project & Roofing Ltd delivers waterproof flat roofing across London to a high standard.
