GRP Fibreglass Roofing

A GRP fibreglass roof is built on site from glass-fibre matting and resin that cure into a single hard covering. Because it is formed in place, it wraps around corners, upstands and awkward details without the seams that other coverings need.

The old roof is stripped and new decking boards are laid, then the matting is wetted out with resin, the edges and upstands are formed with trims, and a coloured top coat finishes the surface. The result is a clean, smooth roof that suits extensions and areas on show.

One Seam-Free Covering

Matting and resin cure into one hard skin across the roof, with no joints in the field for water to work into.

Suits Awkward Shapes

Formed in place, GRP follows bays, corners and upstands neatly where sheet coverings need cuts and joints.

A Clean Finish

The coloured top coat gives a smooth, tidy surface that looks right on extensions that are seen every day.

Owner Run

02

Roof Checked

The deck, fall, edges and upstands are checked so the GRP goes onto a sound, well-drained base.

03

Your Quote

You receive a quote for the fibreglass roof, including new decking where it is needed.

04

GRP Laid

New boards go down, then the matting and resin, the trims and the coloured top coat.

Reviewed Together

We review the completed work with you and confirm everything has been done as agreed.

FAQs

Fibreglass Roof Questions

What Is a GRP Fibreglass Roof?

GRP stands for glass reinforced plastic. Glass-fibre matting is laid on the roof deck and soaked in resin, which cures into a single hard covering, finished with a coloured top coat.

What Is the Difference Between a Fibreglass & a Rubber Roof?

Fibreglass is formed on site and cures hard, which suits awkward shapes and areas on show. Rubber is a flexible membrane laid with few or no joints. Both work well on garages and extensions laid on sound decking.

Can a Fibreglass Roof Take Foot Traffic?

A GRP roof can take light foot traffic for things like cleaning windows or gutters. If a roof will see regular foot traffic, that is discussed when the roof is quoted.

Can a Fibreglass Roof Be Repaired?

Cracks and damaged areas in an existing GRP roof can often be repaired by bonding new matting and resin over them. Widespread cracking or soft decking usually means replacement is the better option.

Is Fibreglass Suitable for a Bay Window Roof?

Yes. Because GRP is formed in place, it is a neat way to cover bay windows, porches and other small roofs with corners and curves.

How Do I Get a Quote for a Fibreglass Roof?
