Stop the Leak Instantly. Finish the Job Efficiently.
Flash-Dam is the instant temporary water dam that controls active roof leaks — even on wet surfaces, even in the rain.
The Problem
Roofs don't leak until it rains. Keeping water away from the repair area is key to a successful service call. With labor rates rising, do you want two trucks at a service call?
How Flash-Dam Works
3 Steps layout:
Step 1 — Pour & Position
Apply Flash-Dam powder around the leak path. The powder adheres to wet surfaces and forms a ridge.
Step 2 — Water Activates the Barrier
As water touches Flash-Dam, it reacts and creates a temporary dam that redirects and contains water flow.
Step 3 — Clean, Prep & Repair
With water controlled, the surface becomes workable. You can now properly clean and repair the roof — even during rain.

- Two guys and a blower
