About Our GRP

At Joseph Parr Bradford, we supply a full range of roofing GRP kits, tools, and accessories

GRP is also known as fibreglass roofing and is a popular flat roof system as it is lightweight, highly waterproof, and long-lasting.

Whether you are looking for GRP for garages, extensions, or commercial builds, we have materials that you need for your project.

What is GRP Roofing?

GRP (Glass Reinforced Plastic) is a composite material made from a polyester resin and reinforced with fine glass fibres.

Once cured, it forms a seamless, hard-wearing, and fully waterproof surface. Unlike felt or bitumen-based roofs, GRP does not crack, blister, or deteriorate when exposed to UV light and extreme weather.

Key Benefits of GRP Roofing

It has a lifespan of up to 30 years with correct installation, and since it has no joints, it is very leak resistant.

GPR is also resistant to UV, frost, and temperature changes and does all that while being low maintenance requirements

Types of GRP Roofing Kits

We stock GRP kits in a range of sizes, from small projects to large-scale commercial roofs.

Each kit typically includes resin, topcoat, fibreglass matting, hardener, and jointing tape, with measured quantities to reduce waste.

Choosing the Right GRP Roofing Kit

Consider the size of your roof, the level of foot traffic, and whether you need heavy-duty protection.

If you’re unsure how much material you need, our team can advise and ensure you order the right amount.

Common Applications for GRP Roofing

GRP is typically used for:

Domestic roofs such as garages, porches, and extensions
Balconies and roof terraces
Green roofing systems
Commercial and industrial buildings

It is also commonly used with components like flashing for complete weatherproof detailing.
