Our Commercial Roof Repair Process in San Jose
Commercial Roof Survey
A certified San Jose 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 seismic activity, wildfire smoke, and dry-season heat on San Jose 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 Jose. 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 Jose and required by most CA property management agreements.
Warranty & Maintenance Plan
You receive workmanship warranty documentation and a biannual inspection schedule for your San Jose property. Regular maintenance is critical given the demands of seismic activity, wildfire smoke, and dry-season heat on commercial flat roof membranes.
