Expert Flat Roofing for North London Properties
EPDM rubber, GRP fibreglass and high-performance felt systems for extensions, garages, dormers and commercial properties. Long-life installations with manufacturer-backed guarantees.
Why Your Flat Roof Matters
Flat roofs are everywhere in North London — on rear extensions, garage roofs, dormers, bay window overhangs and balconies. They’re also one of the most common sources of leaks and water damage when they fail.
The old-style felt flat roofs that were fitted to thousands of London properties in the 1970s, ’80s and ’90s have a limited lifespan. Many are now cracking, blistering and letting water in. If your flat roof is more than 15 years old, it’s likely approaching the end of its life.
Modern flat roofing systems — EPDM rubber and GRP fibreglass — are a completely different proposition. They’re seamless, UV-resistant, and designed to last 25 years or more with virtually zero maintenance. We install both systems and will recommend the best option for your specific situation.
Our Flat Roofing Promise
- Manufacturer-backed guarantees. We’re certified installers, which means your new flat roof comes with a guarantee backed by the material manufacturer — not just us.
- Proper preparation. A flat roof is only as good as the deck beneath it. We check and replace any rotten decking boards, ensure correct falls for drainage, and add insulation where needed.
- Seamless finish. Both EPDM and GRP systems create a single, seamless waterproof membrane with no joints to fail — unlike traditional felt which relies on overlapping seams.
- Clean, quick installation. Most domestic flat roofs are completed in 1-2 days with minimal disruption.
Which System Is Right for You?
We install all three main flat roofing systems. Here’s how they compare.
GRP Fibreglass
Our Most Popular System
A hard-wearing, seamless fibreglass system that’s applied as a liquid and cures to form a single, watertight shell. Ideal for extensions and areas that may need to be walked on.
EPDM Rubber
Maximum Flexibility
A single-piece rubber membrane bonded to the roof deck. Extremely durable and flexible — it moves with the building without cracking. Perfect for garages and outbuildings.
High-Performance Felt
Budget-Friendly Option
Modern torch-on felt systems are a significant upgrade over old-style poured felt. A cost-effective choice for smaller areas where budget is a primary consideration.
