At this commercial building in San Diego, the flat modified bitumen roof had reached a stage where surface wear was clearly visible. Prolonged UV exposure had started drying and stressing the outer membrane layer, and several transition areas were showing early seam fatigue.
Although the roofing system had not yet developed active leaks, the aging process was evident. The property owner chose to move forward with a professional roof coating application to prevent future water intrusion and preserve the structure before larger deterioration occurred.
The project focused on applying a high-build elastomeric roof coating system designed to seal micro-cracks, reinforce the existing membrane, and reflect heat away from the building, reducing long-term thermal strain across the roof surface.
Project Address: 1685 Palm Avenue, San Diego, CA 92154
Property Type: Light Industrial Commercial Building
Existing Roof System: Modified Bitumen Flat Roof
Service Performed: Commercial Elastomeric Roof Coating
Primary Objective: Waterproof reinforcement and lifespan extension
The goal was to strengthen the existing membrane, reduce UV degradation, and add years of service life without the cost and disruption of a full tear-off replacement.
Flat commercial roofs in San Diego County face constant environmental pressure, including:
Over time, these conditions weaken the outer membrane layer. Even when the base structure remains intact, surface deterioration can lead to seam separation and eventual leaks if left untreated.
Roof coating acts as a protective barrier that slows this process and reinforces the waterproof surface.
During our detailed inspection of the property at 1685 Palm Avenue, we identified:
The structural deck and insulation layers remained stable. This made the building an ideal candidate for roof coating rather than full replacement.
California First Roofing followed a structured multi-step coating procedure to restore surface protection.
The entire roof was power washed to remove dirt, loose particles, and environmental residue. Proper cleaning is critical for coating adhesion.
Minor cracks and seam openings were sealed. Flashing transitions were reinforced prior to coating application.
Where required, a compatible primer was applied to promote strong bonding between the existing membrane and coating layer.
Reinforcement fabric was embedded into high-stress seam areas for added durability.
Multiple layers of reflective elastomeric coating were evenly applied to achieve proper thickness and uniform coverage.
After curing, the entire surface was inspected to confirm consistency, seam coverage, and complete waterproof integration.
To restore and protect the roof at 1685 Palm Avenue, we utilized:
These materials are designed to withstand Southern California climate exposure while maintaining flexibility across temperature shifts.
Following completion of this project, the commercial property now benefits from:
✔ Continuous waterproof surface layer
✔ Reinforced seams and flashing transitions
✔ Reduced surface heat absorption
✔ Slower membrane deterioration
✔ Extended lifespan of the existing roof system
✔ Reduced likelihood of future leak formation
The reflective coating also helps lower rooftop temperatures, which can support improved interior comfort levels during hot months.
Roof coating is a strategic investment when the underlying roof structure remains stable. Compared to full roof replacement, coating offers:
For commercial properties across San Diego County, roof coating can add several years of performance when applied at the appropriate stage of membrane wear.
