How Much Fall On Flat Roof. According to bs 6229 (flat roofs with continuously supported flexible waterproof coverings) and bs 8217 (reinforced bitumen membranes for roofing): The minimum fall for a flat roof is 1:80 which means that for every 80cm along the roof drops 1cm. If flat roofs are to work well, they have to have a slope, known as a fall, to shed rainwater. At this design fall, normal construction tolerances can be accommodated resulting in a typical finished level of 1:80. To achieve a fall of 1:80 you may need to. There are several methods of building in a fall: Any potential deflection of the structural members and decking under dead and imposed loads (a. According to bs 6229 & bs 8217, flat roofs should be designed with minimum falls of 1:40 to ensure a finished fall of 1:80 can be achieved, allowing. There are guidelines laid down that designers can follow to design the roof with a drainage fall (gradient) of 1:40. Hence a ten metre run requires 250mm of fall from high to low point. The fall should never be less than 1:80 and preferably about 1:40. In real terms, a 1:40 fall equates to 25mm per metre run of roof. “all flat roof surfaces (including gutter beds) should be designed with a fall of 1:40, to ensure that finished drainage falls of 1:80 are achieved. When specifying a fall for a flat roof, the designer should take account of: Concrete roofs can be finished with.
