Flat Roof Coating & Waterproofing in San Diego, CA
1685 Palm Avenue, San Diego, CA 92154
Light Industrial Commercial Building
Project Overview
About This Project
A commercial building's flat modified bitumen roof showed visible surface wear from prolonged UV exposure. The outer membrane displayed drying and stress, with several transition areas exhibiting early seam fatigue. Although active leaks had not yet developed, the property owner chose preventive roof coating application. The project applied a high-build elastomeric roof coating system to seal micro-cracks, reinforce the existing membrane, and reflect heat away from the building — extending service life at a fraction of full replacement cost.
Initial Assessment
Conditions Found
- Surface drying and minor cracking in high UV-exposure areas
- Early seam fatigue along membrane overlaps
- Small gaps near flashing transitions
- Minor granule loss on exposed surfaces
- Functional drainage with no major ponding
- Structural deck and insulation layers remained stable
What We Used
Materials
- Reflective elastomeric roof coating
- Seam reinforcement fabric
- Bonding primer compatible with modified bitumen
- Waterproof crack and joint sealant
How It Was Done
Installation Process
Every project follows a structured, supervised process — from site assessment to final walkthrough.
Outcomes
Project Results
- Continuous waterproof surface layer created across the full roof
- Reinforced seams and flashing transitions
- Reduced surface heat absorption with reflective coating
- Slower membrane deterioration extending system lifespan
- Lower cost than full replacement with minimal operational disruption
