Why Choose Us

Why choose GRP for your Wokingham flat roof?

Many older flat roofs in Wokingham are constructed using multi-layer mineral felt, which often fails at the seams, leading to pooling water and underlying timber decay. Our Glass Reinforced Polyester (GRP) systems offer a superior alternative. Because GRP is applied as a seamless, cold-laid liquid membrane, it eliminates the vulnerable joints common in traditional felting. This process is not only safer as it removes the need for open-flame torching, but it also creates a robust, UV-resistant surface capable of withstanding light foot traffic.

Who We Are

Compliance and thermal performance in Wokingham

When we undertake a full flat roof replacement, we pay close attention to current Building Regulations. Specifically, Part L thermal requirements often mandate an upgrade to your insulation levels whenever a significant portion of the roof covering is replaced. We ensure your new flat roof installation meets these modern standards, helping to improve your home's energy efficiency and prevent condensation buildup within the roof structure.

Expert diagnosis for local flat roof issues

If you are experiencing leaks or noticing signs of surface degradation on your flat roof, our team is ready to help. We conduct thorough site surveys to trace the exact source of water ingress. Often, issues stem from failing upstands at wall abutments or brittle edges where the roof meets the guttering. Whether your property is a modern build or a period home in Wokingham, we assess the structural integrity of your decking to determine whether a targeted repair or a complete GRP renewal is the most cost-effective long-term solution.
