GRP fibreglass roofing is a genuinely different approach to flat roofing compared to sheet membrane systems, and it's worth understanding how it actually works. Here's an explanation from Back to Back Roofing Worcester.
What Is GRP Fibreglass Roofing?
GRP stands for glass reinforced plastic — a liquid resin system reinforced with fibreglass matting, applied on-site and cured into a rigid, genuinely seamless surface. Unlike sheet membranes, there are no joints at all once it's cured.
Why GRP Performs Well on Flat Roofs
- Completely seamless once cured, removing joint-related leak risk entirely
- Durable and resistant to standing water issues
- Can be walked on more readily than some other flat roof systems
- Available in a range of finishes and colours
How GRP Is Installed
- Roof deck prepared and primed. A sound substrate is essential for a good GRP result.
- Fibreglass matting laid and saturated with resin. Building up the reinforced layer.
- Topcoat applied for UV protection and finish. This also determines the final colour and texture.
- Cured and inspected. Weather conditions during installation genuinely matter for GRP, which is why timing is planned carefully.
Things Worth Knowing About GRP
- Installation is weather-dependent, needing suitable conditions to cure properly
- A genuinely durable, long-lasting system when installed correctly
- Good for roofs where a walkable surface is useful
- We'll advise honestly on whether it suits your specific roof and timeline
