Why Choose Us

Why Choose GRP Fibreglass for Your Flat Roof

Glass Reinforced Polyester, commonly known as GRP, offers a superior, cold-applied membrane that creates a completely seamless finish. Unlike traditional multi-layer mineral felt which can suffer from cracking at the joints, fibreglass creates a single, continuous layer that is impervious to water. This makes it an excellent choice for flat roof extensions, dormers, and balconies in Bushey. Because it is cold-applied, there is no need for heat or flames during installation, making it a safer option for residential properties.

Solving Common Flat Roof Issues in Hertfordshire

Many flat roofs on older properties in Bushey eventually develop problems such as pooling water, sagging decks, or failing seams. Our team is experienced in diagnosing these specific issues.

How does GRP compare to other roofing materials?

Property owners often ask about the durability of GRP compared to standard felt or rubber membranes. While felt can degrade over time due to UV exposure and thermal movement, GRP is a hard-wearing, long-lasting material that resists weathering. It is strong enough to withstand light foot traffic, which is ideal if you are looking to create a functional balcony or terrace. Our installations are designed to be maintenance-free, offering excellent peace of mind for local homeowners.
