Flat Roofs

Flat roofs require precise installation and proper drainage detailing to prevent pooling water and leaks. We install and repair high-performance flat roofing systems built to withstand the British weather.

When You Need Flat Roofs

Pooling standing water remaining on your flat roof 48 hours after rain. Cracks, blisters, or tears forming in the old felt or membrane surface. Damp patches or peeling wallpaper appearing on ceilings directly beneath the flat roof. An ageing roof system that has exceeded its 15 to 20-year lifespan.

How We Do It

We assess the condition of the deck, insulation, and waterproof membrane. We strip away failing layers down to the sound timber deck where necessary. We install high-performance roofing felt or modern waterproofing membranes with secure edge trims. We test the drainage and leave your property clean and watertight.

What to Expect

Most domestic flat roof replacements take between 2 to 4 days depending on the size and weather conditions.

Flat Roofs FAQs

We install high-performance multi-layer roofing felt and modern flat roof systems chosen for their durability and weather resistance.
Pooling water is often caused by sagging deck timbers or inadequate falls toward the drainage outlets, which we can correct during replacement.
If the damage is localized, we can often carry out targeted patch repairs. If the membrane is failing across the whole area, a full replacement is more cost-effective.
