Why Choose Us

Why Choose GRP for Your Flat Roof

Unlike traditional multi-layer mineral felt, which often fails at the seams and degrades under UV exposure, GRP is a cold-applied, glass reinforced polyester system that provides a completely seamless finish. By eliminating joints, we remove the most common entry points for water ingress. This method is particularly effective for complex roof shapes, such as those found on local post-war properties or modern architectural extensions, offering a robust, maintenance-free solution that resists pooling water and light foot traffic.

Who We Are

Meeting Regulations and Structural Standards

When we undertake flat roof installation in Chorleywood, we ensure all works are compliant with current Building Regulations, specifically Part L regarding thermal performance. If your existing flat roof is over 25 percent of the roof area, thermal upgrades are often required during the replacement process. Our team assesses the condition of your existing roof structure to ensure that the new fibreglass system is applied to a suitable deck, providing a long-term solution that meets modern energy efficiency standards.

Addressing Common Flat Roof Failures

We frequently help local property owners resolve persistent leaks caused by blistered felt, shrunken flashings, or mortar issues at the roof abutments. Rather than applying temporary patches that often fail during the next wet season, we provide a permanent fix through full GRP replacement. Whether you have a garage roof prone to water ponding or a kitchen extension suffering from damp internal ceilings, our survey process helps us determine the exact cause of failure and the most effective way to restore your property’s weatherproofing.
