What is “Leak Stop”?
Leak stops are temporary solutions designed for flat rooves. If there is a flat roof leak, a leak stop is applied to the area affected. The material is powdery at first and when it touches the water, it uses the water path to carry itself into the hole or damaged space in the roof. At this point, it solidifies and acts temporarily as a plug or dam, keeping water out. It can be tricky, however, depending on the size of the hole or how serious the problem is. Leak stops general last a few months and so the need to find a more permanent solution is important.
