Design Specifications Mitring scheme To avoid having 4 layers of overlapping roof sheets, the corners of two sheets must be mitred. Each mitre must be cut straight and cleanly either by hand or by power saw. The angle and size of mitre is governed by the end and side lap dimensions. It is recommended that a good quality butyl mastic strip is used to seal the overlapping sheets to provide a weatherproof join. Two corners of opposing sheets should be mitred the equivalent of the head and side lap (i.e. maximum 110mm x 150mm) with a gap between sheets of 3 – 6mm. Sheets on the perimeter of the...
