1: Roof leaks and moisture
With any roof – no matter what type – if you’ve got roof leaks, then you’ve got a problem.
Leaks can occur for a number of reasons. Built-up roofs might experience leaks due to flashing details that weren’t fastened properly during installation. “The problems an owner is typically going to have is that 95 percent of leaks occur at flashing details – anywhere the membrane itself is terminated or interrupted, hot bituminous and torch-applied modified bitumen roofs may experience leaks when a proper moisture barrier is not installed underneath a coping cap on parapet walls. The improper installation of flashing is a source of leaks on torch-applied modified bitumen roofs. Inadequate head laps and backwater laps are another mod bit installation problem that can allow moisture infiltration. Water can get under the membrane if the field of roof is installed so that water flows against the lap. The consequences of backwater laps are leaks and blisters, which can lead to roof failure. C.A.R.E. explains.

With cold-applied modified bitumens, improper storage of materials can result in moisture infiltration built into the roofing system, and under-application of adhesive can result in poor lamination and roof leaks.
Leaks can result when single-ply membrane roofs are installed with poor seams. You’ve got to have good seams with single-ply, because if you don’t, you don’t have much. The membranes themselves will hold water. You’ve got to have the seams either glued or heat welded.
