Flat Roof Decking

Once we have removed your old roof down to joist level, we install new insulation. The insulation can be either be between the joists (a cold roof construction) or on top of the joists (a warm roof construction). We then install the best OSB3 2400X600mm tongue & groove boards, these are fixed with 75 x 6mm exterior grade screws. A flat roof is only as good as it's decking, so we make the time to lay and fix the boards correctly. Please visit Smartply if you are interested in the specification and the benefits of using OSB3, tongue & groove boards.

GRP Edging Trim

We then install batten around the perimeter of your flat roof, this is to help support and hold the edging trim away from the wall below. GRP trim is then installed using galvanized clout nails at 50mm intervals, the trim is also bonded onto the batten using a flexible adhesive. We take great care getting the trims fixed straight and true to the new decking as this is the detail you will see from your garden or driveway.

Fibreglass To Last A Lifetime

The fibreglass matting is then cut to length and laid onto the boards with a good quality resin below and on top of the matt. The resin is thoroughly consolidated with a paddle roller, which removes any air and makes the glass fibre waterproofing system a uniform quality and thickness. 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, our fibreglass waterproofing system is produced with a minimum matt wieght of 600 g/m². We take our time and use highest quality materials to ensure your fibreglass flat roof will last a lifetime.

Topcoat Can Be Any Colour

Once your roof is dry we sand down the new roof area and apply a waxed topcoat, creating a smooth, impervious, aesthetically pleasing flat roof in a colour of your choice. Once completed your new flat roof will last for over 25 years. This system is recommended for flat roof extensions, garages, balconies, dormers and walkways. We do our flat roofing in areas such as Chepstow, Monmouth, Cardiff, Abergavenny, Bristol, Bath, Taunton, Penarth, Crickhowell, Brecon and Lydney, in fact all of South Wales and the surrounding areas.
