GRP Fibreglass Roof

Best for

Bay-window roofs, small porches, dormer cheeks — anywhere the finish is visible and a seam would show.

Where it fails

• Hairline crazing if laid too thick or in cold conditions
• Edge trims pulling away when fixings are skimped
• Difficult to repair invisibly once weathered
• Wrong-gauge tissue or cheap resin shows up in 5 years

Our repair approach

We lay GRP at 450g chopped strand mat with proper trim returns, and avoid pouring resin in sub-10°C weather — most failures we patch trace back to that.
