For new installations on extensions and garage roofs in Llandudno, we recommend GRP (fibreglass) as the primary choice. It handles coastal moisture and temperature fluctuations better than felt, carries a 25-year guarantee, and is maintenance-free in most cases. EPDM rubber is a good option for large areas where GRP cost is prohibitive.
GRP fibreglass roofs typically last 25–40 years with zero maintenance. EPDM rubber systems last 20–30 years. Traditional felt roofs last 10–15 years in good conditions — less in Llandudno's salt-air environment, which is why we don't recommend felt for new installations here.
A typical rear extension flat roof (20–30 square metres) costs £1,800–£3,500 for GRP. Garage flat roofs run £1,200–£2,500 depending on size and condition of the existing deck. Full quotes provided after a free survey.
In many cases yes. If the existing deck is structurally sound and the failing area is localised, we can carry out targeted GRP or EPDM repair. We survey honestly and won't recommend replacement if repair is the right solution.
No call-out fees. No obligation. Just an honest quote from a local Llandudno roofer who turns up when they say they will.
