A properly laid fibreglass roof also known as GRP Roofing, will last for at least 30 years with no measurable deterioration.
Hear at Ashford Building Services we have been replacing old flat felt roofs with fibre glass systems for the past 4 years in and around the surounding areas of Ashford Kent.
The history of GRP
GRP (glass reinforced polyester) was discoverd in the late 1940 s. It was quickly adopted during the 1950 s and 60 s for a wide range of applications where its corrosive-proof properties, allied with its high strength and excellent apperarance, soon provided to be invaluable , Its first main application was for boat building, where it gained acceptance in the 50 s and is still widely used today. The uses for GRP have since broadened to the extent that it has now become the standard material for the construction of small craft, water tanks, building ponds and pools, roof lights and of course high performance waterproof coatings. In the last 10 years a rapid growth has occured in the GRP industry as more and more people realise the benifits of GRP.
What is a GRP roof
A GRP roof is a single-ply GRP laminate applied in situ over a good quality deck. The roof is finished with pre-formed GRP edge trims and a coat of pre-pigmented topcoat which comes in grey as standard but can be in most colours to match the suroundings, when GRP is used to construct a boat, GRP will provide complete waterproofing protection for the boats entire lifespan of twenty plus years without the need for maintanance or replacement. This same level of performance is easily replicated on a domestic roof and suprisingly for not much more than the traditional 3 ply felt flat roofing system.
