GRP stands for glass reinforced polyester. Over the last 60 years it has proved to be an extremely robust and long-lasting water and rot proof material which is used in the boat building and construction industries. Fibreglass GRP is an excellent solution for both new and old troublesome flat roofs. Fibreglass is one of the most durable and water resistant materials available. Among its other qualities are a resistance to fire and a heat, electricity and a great sound insulator. The thermal insulation properties alone will generate considerable savings on heating and power bills. It will also give added value to any property. Fibreglass Roofing can be used on any style of roof from pitched to flat and for any roofing purpose including extensions and porches.

Below is a round up some of the most asked questions regarding Fibreglass GRP.
A. A GRP Roof or gutter lining will remain virtually maintenance free for a period in well in excess of the twenty five year guarantee period. GRP roofs that have been protected from UV degradation by chippings on the gel surface should remain serviceable for considerably longer. 40 year old GRP Roof lights are still in use (todays materials are far superior and have built in UV protection). After twenty five years, a new gel surface can be applied to roofs and gutter linings extending life expectancy even further (subject to specific site conditions). Even 40 year old GRP roof lights can be refurbished with a new gel-coat!
A. In many cases GRP is a cheaper alternative to traditional materials due to faster installation and the reduced need to strip out existing materials, roof sheets/tiles or glazing bars etc. The price per roof or gutter lining is often dictated by site conditions, please contact us for further information and pricing.
A. A GRP roof is perfectly safe to walk on, and is far less likely to be damaged compared to traditional roofing materials. Pedestrian access can be easily incorporated in roofs or gutter linings and specific specifications can be used for roof gardens or balcony/patio areas etc.
A. Fibreglass has for many years been used successfully on pitched roofs as well as flat areas. Rooflights and Velux installations are easily incorporated into the new GRP roof.
A. As the GRP roof systems we use lend themselves to over-roofing (providing the existing deck is in serviceable condition) it is not always necessary to strip the existing roof covering and decking. An initial site survey should establish whether the existing deck should be replaced as per building regulations.
A. Fibreglass roofs are much stronger than traditional felt roofs , and so make excellent roof gardens, balconies and patio areas.
A. GRP roofs are ideal for the incorporation of flashing details and specific soakers for Velux units or rooflights etc. Independent GRP soakers or flashing units can also be manufactured on site for use on a variety of roof surfaces (tile, fibre cement sheet, slate etc.) although we still advocate the use of a lead flashing to the perimeter of our GRP roofs to aid in the transmission of moisture vapour.
A. A gutter detail is easily incorporated into the roof structure, as are most shapes and roof pitches.
A. All of our work is guaranteed. Please contact us for specific information and insurances etc.
