This old mineral felt roof was covering ten garages. We stripped the old leaking mineral felt covering and removed all the old decking, fixed new joists then new decking with Sterling board (not ply). Then we re-roofed the garages using EPDM rubber as this is a long-lasting material with a lifespan of over 40 years, and is perfect for large open areas.
Replacement of an old flat asphalt roof using insulation covered with EPDM, a skylight and a new insulated tank box. We had to have a tin roof over the roof for this project, because we knew the roof would be open for longer than a day. The new flat roof will be insulted to the new building regulations. New flat roofs today have to be insulated to a very high standard today.
This new flat roof is being laid using Kingspan’s ‘cut to falls’ insulation, then covered using EPDM rubber, single ply as the waterproofing membrane. This roof will carry a 20 year insurance-backed guarantee. New roofs today need to be insulated to a very high standard and the depth of insulation on this roof is very good.
Single ply flat roof covering rubber EPDM not firestone, over torch on mineral felt, asphalt, 80mm Kingspan insulation glued to decking, new flashings box gutter, scaffolding, no lead, 20 year guarantee. Part L of Building Control was not applicable.
My guess is that this roof wasn’t laid by specialists trained in EPDM rubber roofing materials. The quality of the workmanship is very poor, and EPDM will get a bad image if untrained people are allowed to carry on purchasing and installing this excellent material incorrectly. It was found that the problem on this roof was the leak from the slates at the back of the tiles and not the Rubber roof at all.
