Our Commercial Roof Repair Process in San Diego
Commercial Roof Survey
A certified San Diego commercial contractor surveys the full roof system — membrane, seams, penetrations (HVAC curbs, drains, skylights), perimeter flashings, and parapet walls. Moisture scanning identifies water trapped in insulation — a common result of coastal salt air, Santa Ana winds, and UV exposure on San Diego commercial buildings.
Scope & Documentation
Written scope with itemized costs, material specs, and timeline — formatted for property management review, insurance adjusters, and building owners in San Diego. Commercial documentation is more detailed than residential and our contractors know the standard.
Commercial-Grade Repair
Repairs use materials matched to your existing system — heat-welded TPO, EPDM adhesive, torch-applied modified bitumen, or BUR flood coat. All penetration flashings are inspected and resealed. Work is scheduled to minimize tenant disruption.
Water Testing
Flood testing or electronic leak detection confirms the full repaired area is watertight. This step is standard for commercial work in San Diego and required by most CA property management agreements.
Warranty & Maintenance Plan
You receive workmanship warranty documentation and a biannual inspection schedule for your San Diego property. Regular maintenance is critical given the demands of coastal salt air, Santa Ana winds, and UV exposure on commercial flat roof membranes.
