Front Fascia Flat Roof DetailSteven Dickinson
In this video, our principal surveyor – Steven Dickinson, explains problems with insulating a roof using the warm and cold roof construction methods.
Whatever new flat roof covering you choose EPDM rubber, Kemper, Liquid Rubber, Triflex, Mariseal etc; if the specification of the insulation is not correct you could have problems. Some of the problems you may have are rotting joists and sweating of the roof because of thermal bridging.
Warm flat roofs are very forgiving, however, if not installed correctly, cold spots are easily built into the roof and problems with sweating may occur.
