The pictures below are of one of our latest flat roof repair jobs for a roof on a property in Lewisham in Greater London.
The roof in question was approximately 200 M2 and was constructed of stramit boards and asphalt. The roof was leaking severely with numerous cracks. The parapet walls were also badly in need of repair with crumbling brickwork that needed to be replaced.
Firstly we cleared and cleaned the flat roof area and repaired the numerous cracks in the substrate with exterior grade latex. We then rendered the parapet walls to complete the repair. The whole roof, including the parapet walls, was then fully encapsulated using the 3M Skotchkote Roofing System to give a fuly bonded, completely waterproofed finish.
Solar gain on older flat roof coverings is well documented problem. Solar gain is the heating effect of solar radiation on the flat roof surface. This heating effect will, in time, cause the surface, an asphalt flat roof for example, to deteriorate and slump causing cracks and fissures which will inevitably lead to water ingress. Modern roof coverings can help to minimize solar gain and significantly increase the integrity of the roof surface, maximizing durability and increasing the roof’s life.
Below are some pictures of a recent Flat Roof Recovery domestic roofing project for a house in Chelsea, West London. We were asked to recover an asphalt roof that was badly in need of repair. We overlayed the existing asphalt roof using the Sealoflex system and finished in white to help to reflect the heat and UV rays which cause solar gain, significantly extending the potential life of the roof.
