GRP Flat Roofs

Traditional felt and rubber flat roofs often crack, blister, and leak after a few years of British weather. We install high-performance GRP fibreglass flat roofs that form a continuous, joint-free waterproof membrane built to last 30 years or more.

When You Need a New Flat Roof

Water pooling on your roof surface after every heavy downpour. Internal ceiling damp spots or peeling paint right below your flat roof. Felt or asphalt bubbling, cracking, or showing exposed reinforcement mesh. An existing flat roof that is over 15 years old and requires constant patch repairs.

How We Do It

We strip your old flat roofing down to the joists and check the structural timber condition. We install a brand new 18mm OSB3 tongue and groove deck along with edge trims secured with heavy-duty fixings. We apply catalysed resin, roll out high-grade fibreglass matting, and consolidate the layers to eliminate air bubbles. Once cured and sanded, we apply your chosen UV-resistant topcoat for a seamless, watertight finish.

What to Expect

Most standard flat roof installations are completed within 2 to 3 days with minimal disruption to your daily routine.

GRP Flat Roofs FAQs

GRP fibreglass forms a completely seamless, joint-free membrane that is UV-resistant and exceptionally durable. Unlike felt, it cannot be torched or punctured easily and typically lasts over 30 years with virtually zero maintenance.
Yes, we can install GRP roofs year-round. However, the OSB3 deck and fibreglass materials must remain completely dry, so we set up protective weather shelters on site during wet conditions.
We generally recommend warm roof construction where rigid insulation is placed above the rafters. This retains heat efficiently and prevents condensation rot, which is ideal for the UK climate.
Our flat roof installations come with manufacturer guarantees ranging from 20 to 40 years depending on the system chosen, plus a 10-year insurance-backed guarantee.
