GRP Roofing

GRP roofing delivers a tough, seamless fibreglass surface that outperforms traditional felt. We apply a minimum of 900 CSM with two layers of 450 CSM to ensure absolute waterproof integrity.

When You Need GRP Roofing

Your old felt garage roof is cracking, sagging, or letting water in. You are building a new single-story home extension and need a dependable flat roof. Standing water pools on your current flat roof after heavy rainfall. You want a low-maintenance flat roof that will not crack or blister under UV rays.

How We Do It

We strip away old degraded felt and inspect the timber decking beneath. We lay down high-quality OSB3 decking boards to create a solid foundation. We laminate the roof using two layers of 450 CSM chop strand matting with high-grade resin. We apply a UV-resistant topcoat in your chosen slate grey or standard finish.

What to Expect

Most domestic GRP roofs are completed within one to two days with minimal disruption to your property.
