Flat Roof Decking

Once we have removed your old flat roof down to joist level, we install new insulation as required. The insulation can be either between the joists (a cold roof construction) or on top of the joists (a warm roof construction). We then install the very best OSB3 2400 X 600mm tongue & groove boards, these are fixed with 75 x 6mm exterior grade screws, not nail guns. A fibreglass flat roof is only as good as it's decking, so we make the time to lay and fix the decking boards correctly. Please visit Smartply if you are interested in the specification and the benefits of using OSB3, tongue & groove boards. 

GRP Edging Trim

Once your new decking is completed we install 50 x 25mm tanalised batten around the perimeter of your flat roof, this is to help support and hold the edging trim away from the wall and guttering below. GRP edge trim is then installed using galvanized clout nails at 50mm intervals, the fibreglass trim is also bonded onto the batten using a fibreglass friendly flexible adhesive. We take great care getting these fibreglass edging trims fixed straight and true to your new flat roof decking, this is the detail you will see from your garden, driveway or window and we want it to look good.

Fibreglass To Last A Lifetime

The fibreglass chopped strand matting is then cut to length and tailored for details like skylights or any other protrusions. The matting is then laid onto the boards with a premium quality resin both below and on top of the matt. The resin is then thoroughly consolidated with a paddle roller, which removes any air and makes our glass fibre flat roofing waterproofing system a uniform thickness and quality. Again, we take our time to do this, as the correct thickness of the fibreglass and achieving the correct resin:matt ratio is very important. Unlike many systems used by others, our fibreglass flat roof waterproofing system is produced with a minimum matt wieght of 600 gm/m². We take our time and use highest quality materials to ensure your new fibreglass flat roof will not only look great but also last a lifetime.

Topcoat Can Be Any Colour

Once your new fibreglass roof has cured we lightly sand down the entire area and then apply a coloured waxed topcoat, creating a smooth, impervious, aesthetically pleasing flat roof in a colour of your choice. When completed your new fibreglass flat roof will last for over 25 years. This system is recommended for flat roof extensions, garages, balconies, garden buildings, dormers and walkways. We install our fibreglass flat roofing in areas such as Chepstow, Monmouth, Newport, Cardiff, Abergavenny, Bristol, Bath, Taunton, Penarth, Crickhowell, Brecon and Lydney, in fact all of South Wales & the South West of England.
