GRP Fibreglass Roofing in Coventry
When your flat roof requires an exceptionally tough, durable, and completely seamless finish, GRP (Glass Reinforced Plastic) fibreglass is the ultimate solution. Originally developed for marine applications, this system involves applying liquid resin over a fibreglass mat, which cures to form a single, incredibly strong waterproof shell with no joints or weak points.
At L&D Sky High Roofing, we are specialist installers of GRP systems, providing Coventry homes with a modern, robust roofing solution perfect for any flat roof, balcony, or walkway.
The Ideal Solution for High-Traffic & Complex Roofs
GRP’s unique application process and incredible strength make it the perfect choice for specific roofing challenges. Unlike membrane systems, GRP is cold-applied in liquid form, allowing it to mould perfectly to any shape, detail, or upstand, creating a truly monolithic, seamless surface.
Its most significant advantage is its sheer toughness. Once cured, a GRP roof is resistant to heavy foot traffic, impact, and weathering, making it the only real choice for surfaces that will be regularly used, such as roof terraces, balconies, or complex walkways. It provides a sleek, modern finish that is as strong as it is beautiful.
Our Service Process
Step 1: Deck Preparation & Trims
A GRP roof requires a new, clean OSB3 timber deck. We begin by installing this deck and fitting all bespoke GRP edge trims and detailing to create the sealed perimeter for the system.
Step 2: Lamination Process
We then apply a catalysed resin base before carefully laying the fibreglass matting. A second layer of resin is applied over the top, consolidating the layers to form the strong, waterproof core of the roof.
Step 3: Application of Topcoat
The final stage is to apply a durable, pigmented topcoat. This provides the final weatherproof layer, gives the roof its colour and UV protection, and creates the tough, non-slip finish.
A Tough, Seamless & Modern Finish
Choosing L&D Sky High Roofing for your GRP installation means choosing a team of skilled craftsmen. The quality of a GRP roof is entirely dependent on the skill of the installer – from achieving the correct resin mix to ensuring perfect consolidation of the fibreglass mat. We have the specialist experience required to execute this process flawlessly, delivering a GRP roof that is not only 100% waterproof but also architecturally sharp and built to withstand years of use.

NuneatonYour GRP Roofing Questions
Neither is "better," they are just suited for different applications. GRP is stronger and better for roofs with foot traffic or complex shapes. EPDM is more flexible and often more cost-effective for large, simple roof areas where walk-on durability is not the primary concern. We will help you choose the right one.
The installation process is highly weather-dependent, as the resins require dry conditions and specific temperatures to cure correctly. A typical residential GRP roof can often be completed within 2-3 days, but we will always provide a realistic timeline based on the project and forecast.
No. A GRP system must be bonded directly to a new, clean OSB3 timber deck. Applying it over any other surface will cause it to fail and will void its guarantee. We always strip the roof back to the joists to ensure a sound and correct installation.
