Fibreglass (GRP) Roofing in Berkshire

GRP fibreglass creates a tough, seamless waterproof covering that gives flat roofs a clean, contemporary finish. The system is formed on site over a properly prepared deck using glass-fibre reinforcement and resin, before being finished with a protective topcoat.

Because GRP forms a rigid, joint-free surface across the main roof area, it works particularly well on roofs with more detailed shapes and where a neat appearance is important. It is commonly used for extensions, dormers, garages and other domestic flat roofs. Careful deck preparation, correct falls and properly formed edges and drainage details are essential, so we make sure the entire roof is prepared correctly before the GRP system is installed.

Common questions

Fibreglass (GRP) Roofing FAQs

Is fibreglass better than rubber?

For a roof that gets walked on, or a balcony, GRP wins because the surface is harder wearing. For a simple garage or extension roof, EPDM rubber is often the more economical choice. We will advise on the right one.

Does a GRP roof need a dry day?

Yes. Fibreglass needs to be laid onto a dry deck in suitable weather to cure properly, so we plan the work around the forecast.

What is GRP?

Glass-reinforced polyester, a fibreglass system laid wet and cured into one solid, joint-free surface with a hard top coat that copes with foot traffic.

Can I have a walk-on balcony finish?

Yes. GRP is ideal for balconies and walkways, and we can add an anti-slip finish where it is regularly used.

How long does a fibreglass roof take to fit?

A typical domestic GRP roof takes a couple of days, as each layer needs time to cure. We plan it around dry weather.
