The existing roof covering consisted of 20mm asphalt with felt patch repairs in places. This property was also uninsulated.
The asphalt was over 15 years old and had splits and gas blisters which allowed water ingress into the building. This had been happening for some time without being treated and subsequently caused the timber substrate to rot and slump.
London Roofing stripped the whole roof back to the rafters and cut out all the rotten timbers and replaced with new. New Waterproof Board (WBP) ply was installed along with 130mm flat board insulation bringing it in line with part ‘L’ building regulations. This was then finished with a 20 year cold applied liquid membrane. We also installed a polycarbonate access hatch to allow maintenance to be carried out to the roof area, like the clearing of gutters/outlets of tree fallen debris. We issued the client with a 20 year single point labour and materials guarantee upon completion.
