Frequently asked questionsQuestions about waterproofing.
These answers provide a practical starting point. The building, roof assembly, permit jurisdiction, and observed conditions determine the final recommendation.
Is roof coating the same as waterproofing?+
A coating may be part of a waterproofing or restoration system, but suitability depends on the existing roof, moisture, adhesion, preparation, details, drainage, and the coating’s approved use.
Can waterproofing stop an active roof leak?+
It can when the actual entry path and failed detail are correctly identified and the substrate can receive a compatible repair. Surface application over an unknown defect is less reliable.
Why do transitions leak?+
Transitions combine different materials, movement, slopes, fasteners, terminations, and water flow. They require compatible detailing that maintains continuity across the change.
