Flat Roofs in Stockport & Greater Manchester

The three-layer felt roofs fitted on extensions and garages in the 70s and 80s are long past it. Modern single-ply and fibreglass systems last decades, not years.

Flat Roofs across Stockport and Greater Manchester

Flat roofs get a bad name in this country almost entirely because of what was fitted forty years ago. Old pour-and-roll felt splits, blisters and shrinks; once water gets under it, the deck below starts rotting quietly and you don't know until the ceiling goes.

We fit three modern systems depending on the roof. EPDM rubber is a single seamless sheet — brilliant on garages, extensions and anything simple, with a 20-year guarantee. GRP fibreglass is laid wet and cures into one solid shell, which makes it ideal for balconies, dormers and anywhere with trims and upstands. High-performance torch-on felt still has its place on larger commercial roofs and where a walkable, hard-wearing finish matters.

Whatever the covering, the important part is underneath: falls that actually drain, a sound deck, and insulation that meets current Building Regs so you're not heating the sky.

How long does a flat roof last?
A modern EPDM or GRP flat roof, correctly detailed and with proper falls, should give you 25–30 years. The guarantee on the membrane is typically 20 years. Old felt roofs generally manage 8–10 years at best.
Can you overlay my existing flat roof?
Sometimes, but we're cautious about it. If the deck below is wet or rotten, overlaying just hides the problem for another few years. We'll cut a test area and tell you honestly which it is.
Does a new flat roof need building control?
If you replace more than 50% of a flat roof, Building Regulations require you to upgrade the insulation. We factor that into the quote so there are no surprises. We're registered with the NFRC Competent Person Scheme, so we can self-certify the work and issue your Building Regulation Compliance Certificate directly — no separate local authority building control application needed.
