SPL Waterproofing delivers professional, high-performance roof sealing and membrane systems to protect properties across Los Angeles, from the coastal breeze of Santa Monica to the intense sun of the Hollywood Hills.

Solving the Challenges of LA Flat Roofs
Flat and low-slope roofs in Los Angeles face extreme conditions. Persistent UV exposure degrades standard materials, while seasonal rains can lead to ponding water and structural leaks. Our systems are engineered specifically for these challenges.
Seamless Membrane Technology
The most common cause of roof failure is seam separation. By using liquid-applied, reinforced membranes, we create a single, continuous barrier over your entire roof. This “seamless” approach ensures there are no weak points for water to penetrate, even in areas with poor drainage.
Cool Roof Benefits for Southern California
Our white, UV-reflective coatings do more than just stop leaks. They are designated as “Cool Roofs,” which:
- Reflect up to 85% of solar radiation.
- Reduce interior building temperatures significantly.
- Lower air conditioning costs during hot LA summers.
- Extend the life of the underlying structural components.
