Roof Deck Waterproofing Services

Roof decks add valuable outdoor space—but without proper waterproofing, they can become one of the most expensive sources of leaks in a building.

Our roof deck waterproofing services are designed to protect both occupied and unoccupied roof decks from water intrusion, drainage failures, and long-term structural damage.

Why Roof Decks Fail

Roof decks are exposed to constant environmental stress:

• Standing and ponding water
• Thermal expansion and contraction
• Heavy foot traffic and furnishings
• UV degradation

Without a properly designed waterproofing assembly, water penetrates beneath the surface and compromises the structure below.

Integrated Waterproofing Solutions

We install complete roof deck waterproofing systems, including:

• Below-tile and pedestal waterproofing membranes
• Plaza deck and inverted roof assemblies
• Drainage mats and protection layers

Every system is designed to move water efficiently away from the structure—not trap it beneath the surface.
