GRP Warm Roof


GRP Warm Roof Cornwall

We install a GRP Warm Roof  which complies fully with the Thermal Insulation regulation throughout Cornwall & Devon. GRP roofing is perfect for Garage roofs, Bay windows, Balconies and flat roofs.

Warm Deck – Insulation is placed on top of the rafters/joists and the roof covering is then placed over the insulation. No ventilation is required for these types of roofs.

Cold Deck – Insulation is placed between the joists/rafters or in between the ceiling joists in the case of a pitch roof. Ventilation is required for these roofs.

Why Choose A GRP Roof?

To ensure our GRP roofs last we use the market leading materials from Crystic Roof,  is an in-situ cold applied advanced roofing system made from glass reinforced polyester, otherwise known as fibreglass. The Crystic Roof GRP roofing system is made exclusively by Scott Barda which is used by proffesionals all over the country because of its easy application and hard wearing properties. Because the GRP fibreglass roof is a cold installation there is no fire risk, a GRP roof is the prefect replacement for tired old felt roofs.

Excellent customer service. Good time keeping. Always updates on work to be carried out. Very clean and tidy even when doing the muckiest of jobs. Would highly recommend. Very pleased with the work carried out on my 40 foot flat roof conservatory.
