Flat Roof Waterproofing

Membrane and seam waterproofing for roofs exposed to standing water or heavy rain, beyond standard coating applications.

Waterproofing treatments reinforce specific vulnerable areas of a roof — seams, transitions, and penetrations most likely to be tested by standing water or sustained rain exposure — with additional sealant or reinforcing membrane layers beyond what a standard coating provides. This is often paired with drainage correction on roofs with a ponding water history, addressing both the water exposure and the areas most likely to fail under it.

Waterproofing isn’t a universal recommendation — it makes the most sense for roofs with a specific, identified vulnerability (a history of seam issues under repeated ponding, for example) rather than as a blanket treatment for every roof.

Common Questions

Is waterproofing the same thing as a roof coating?

They overlap but aren’t identical — waterproofing often involves targeted reinforcement at specific vulnerable points, while a coating is typically a broader surface treatment across the whole roof.

Does waterproofing eliminate the need to address ponding water separately?

No — waterproofing reinforces vulnerable areas but doesn’t correct an underlying drainage or slope problem causing water to pool.

How long does waterproofing treatment typically last?

This varies by product and application, similar to coatings — we can advise on expected longevity for your specific situation.
