New flat roofs and repairs for homes and businesses across North West London. We assess drainage falls and deck condition first - then recommend the right system for your building.
We respond within hours - 24/7 including weekends and bank holidays.
Poor installation and wrong materials. A flat roof installed correctly with adequate drainage falls will last decades. A bodged job with pooling water will fail within a few years regardless of what surface system is on it.
Before we recommend anything, our project manager assesses the drainage falls and the deck condition. If the deck boards are rotten or the drainage isn't right, putting a new surface over the top just delays the problem.
The honest version - not the one that pushes the most expensive option.
| System | Expected Lifespan | Best For | Watch Out For |
|---|---|---|---|
| GRP Fibreglass | 25-40 years | Extensions, garages, any domestic flat roof where longevity matters | Needs correct deck prep - can't go over a wet or rotten deck |
| Torch-on felt (2-layer) | 15-25 years | Budget-conscious jobs where the building value doesn't justify GRP | Quality varies - single-layer felt is a short-term fix |
| Rubber (EPDM) | 20-30 years | Awkward shapes, tight access, low-pitch roofs | Seams at joins can be a weak point if not bonded correctly |
Our default recommendation: For most domestic flat roofs we specify GRP fibreglass. The seamless finish means no joints to fail, and it works out cheaper over the roof's lifetime. We'll tell you if a different system makes more sense for your specific job.
Every flat roof quote starts with this assessment - not a guess from the ground.
We check for rot, movement and moisture in the decking boards before recommending any surface system.
We measure the falls to drainage outlets. Insufficient fall is the main cause of premature flat roof failure.
Pipes, rooflights, upstands and edges - these are where leaks happen if not detailed correctly.
We identify what's there and whether it can be overlaid or needs stripping back to the deck first.
"My house flat roof and pitched both needed to be replaced. The team did really excellent work, given time. I highly recommend them now."
Sometimes. If the deck is sound and damage is localised, a repair is a perfectly good solution. If the surface is cracked and blistering across the whole area you'll be repairing it repeatedly. We tell you honestly which situation you're in.
No. Ponding means the drainage falls aren't right. It accelerates deterioration and eventually forces through any surface system. We assess whether falls can be corrected as part of the quote.
A standard domestic flat roof takes 1-3 days. GRP needs to cure before the topcoat goes on, so we factor that into the schedule. We don't rush the cure time.

Standard flat roofs aren't designed for regular foot traffic. If you need access for equipment maintenance, tell us at the quote stage and we'll specify the right system.
