Roof Waterproofing

The roof takes the worst of sun, rain and movement, and every failure shows up on someone's ceiling. This system builds seamless, UV-stable waterproofing with detailing that outlasts the membrane itself.

How the system works

Liquid-applied membranes form a continuous, joint-free layer that follows upstands, drains and penetrations, the places where roll systems fail. Surface preparation and primer selection anchor the system, and reinforcement at details handles the movement concentrated there. UV-stable topcoats carry the exposure so the waterproofing layer does not.

Common questions

Asked on real sites.

Can I apply over an existing old membrane?

Sometimes, after adhesion testing and repair of failures. Sometimes stripping is cheaper than the risk. A site inspection settles it quickly.

What about ponding water on my flat roof?

Grades differ in ponding resistance, stated on the TDS. Fix the drainage where practical, and where you cannot, choose the grade that tolerates it.

Can people walk on the finished roof?

Maintenance foot traffic yes, with the right topcoat. Regular use needs a protective wearing layer specified from the start.
