Why Choose Us

Why choose GRP fibreglass for your flat roof

Glass Reinforced Polyester, or GRP, offers a superior alternative to multi-layer mineral felt. Because it is cold-applied, our installation process eliminates fire risks associated with traditional torch-on systems. Once cured, the fibreglass creates a completely seamless, joint-free surface that is immune to the cracking and bubbling often seen on older flat roofs. This robust finish is ideal for our local climate, providing excellent resistance to UV degradation and the ability to withstand light foot traffic.

Who We Are

Addressing common flat roof failures

Flat roof leaks in Yateley are frequently caused by pooling water or failing seams on aged felt roofs. When water gathers in dips, it eventually finds a way through weak joints or cracked material, leading to internal ceiling damage. Our team specialises in identifying these points of failure through a detailed site survey. We ensure that every new installation provides a consistent fall, allowing rainwater to shed efficiently towards the drainage point, preventing future moisture retention and rot in the underlying deck timbers.

Meeting building regulations and thermal standards

When replacing a flat roof covering, it is essential to consider current insulation requirements. We ensure that our roofing projects align with Building Regulations Part L, which often mandates thermal upgrades when the roof deck is exposed during a full replacement. By incorporating high-performance insulation, we not only waterproof your structure but also improve the energy efficiency of your property. Whether you are dealing with a modern garage or a period kitchen extension, our approach balances structural integrity with compliance.

How do you maintain a fibreglass flat roof

One of the primary benefits of a correctly installed GRP system is that it is virtually maintenance-free. Unlike felt or bitumen that requires regular patching, a fibreglass roof is designed for longevity. We recommend occasional cleaning to remove debris or moss that can trap moisture, but beyond that, the surface remains stable and weather-tight for many years. If you suspect your current flat roof is reaching the end of its lifespan, our local team is available to provide an honest, professional assessment of your repair or replacement options.
