GRP (glass reinforced plastic) is resin and glass matting laid on site to form a seamless, rigid surface. It suits roofs with angles and upstands, and can take a top coat in different colours.
Good GRP depends on weather and preparation: resin needs dry conditions and a sound, dry deck. We plan GRP work around that.

GRP fibreglass roofing: common questions
Can GRP be installed in winter?
Only in suitable dry conditions and temperatures. We may reschedule to protect quality.
Is GRP good for balconies?
It can take foot traffic with the right specification. Balconies also involve guarding and structural checks, which we'd discuss at assessment.
Does GRP crack?
Properly specified and installed GRP is durable; poor decks or movement can cause cracks, which is why preparation matters.
