As with most types of roof installations, Flintlastic modified bitumen roof installation begins at the low point of the roof with successive rolls installed so that no laps are against the flow of water. When membrane is applied with hot asphalt, where roof slope is 1" per foot or less, sidelaps are installed perpendicular to the direction of the roof slope. In situations where the roof slope exceeds 1" per foot, rolls are installed with the sidelaps running parallel to the slope direction. APP modified membranes can be installed with sidelaps perpendicular to the slope where roof slope is 2" per foot or less (over 2" install sidelaps parallel to roof slope direction).
Additionally, where roof slope exceeds 1" per foot for SBS modified and self-adhering membranes or 2" per foot for APP modified “back-nailing” of membrane is required. Refer to the General Recommendations section of the CertainTeed Commercial Roof Systems Manual for back-nailing guidelines.
Endlaps are to be staggered. In multi-ply applications, membrane sidelaps must also be staggered.
In multi-ply systems, stagger sidelaps from interply and base sheet sidelaps
