End and side overlap treatment

End laps to main sheeting runs are determined according to the roof pitch and site exposure conditions. Lap sizes and corresponding sealing treatment are given in the table above.

Where wind suction forces are likely to exceed 2000N/sq.m or the length of roof slope exceeds 32m, please refer to current building regulations and procedures.
