What exactly is a “low-slope” roof? Most local building codes consider a roof to be low-slope when its pitch ranges from 4/12 and below, down to and including 2/12. Asphalt shingles, with certain application adjustments, can generally be installed down to slopes of 2:12. But for those lower slopes (from 2:12 down to 1/2:12) you’ll want a membrane system like Roof-Fast.

The important thing for homeowners to understand is that a low-slope roof can’t shed water as quickly as a steeper one can, so there’s a greater chance of water leaking through the roof during periods of prolonged, wind-driven rain. Also, in cold climates, water can back up and leak through shingled roofs if ice dams form at the eave.
