A roof is considered low slope when the pitch of the roof is below 4/12 down to and including 2/12. This means that in a horizontal line 12 feet across, the roof rises between 2 feet to just under 4 feet vertically.

Low slope roofs don’t shed water as efficiently and quickly as steep slope roofs. As a result there is a higher chance of leaks caused by water deflection, wind driven rain and backup due to blocked gutters. BC Building codes and the manufacturers require special applications when installing low slope roofs.

There are essentially two different low slope applications that are designed. Each application provides a 3 layer roofing system that gives added protecting against leaks. These new products have replaced the older 3 ply low slope shingles which were discontinued in the mid-nineties.
