Roof & Roof Deck Waterproofing
SPL Waterproofing provides advanced protection for one of your building’s most vulnerable surfaces: the roof. Whether you have a commercial flat roof or a residential walking deck, our systems are engineered to withstand the harshest California conditions.

Engineered for Southern California
Flat roofs and roof decks in Los Angeles and Orange County face unique challenges. The combination of high UV exposure and low-slope drainage requirements means that standard roofing often fails prematurely.
Walking Roof Decks: The Best of Both Worlds
A roof deck serves as both a roof for the room below and a floor for the occupants above. This dual role requires a specialized approach:
- Structural Integrity: The system must be strong enough to support furniture and foot traffic.
- Absolute Waterproofing: It must maintain a perfect seal to protect the living space below.
- Aesthetic Finish: It should look as good as it performs.
We specialize in decorative, slip-resistant walking deck systems that turn your roof into a functional, beautiful outdoor space.
Commercial Flat Roof Restoration
Don’t replace your roof when you can restore it. Our liquid-applied membrane systems can often be installed directly over existing roofing, creating a seamless, “new” roof surface for a fraction of the cost of a full tear-off.
- No Seams: Eliminates the most common point of failure.
- Sustainable: Reduces landfill waste and construction noise.
- Warranted Performance: Systems backed by manufacturer and workmanship warranties.
