A commercial roof isn't a scaled-up residential roof. It involves different materials, different building codes, different structural considerations, and different stakeholders. Tenant disruption, business continuity, HVAC integration, code compliance across multiple jurisdictions, and phased installation schedules all factor into every commercial project we take on.
All Building Types
Offices, retail, restaurants, warehouses, multi-family, churches, schools, and industrial. We've roofed every building type in the East Bay.
Minimal Disruption
Off-hours installation, phased replacement, noise mitigation, and dust control. Your tenants and customers barely notice we're there.
Complete Documentation
Warranty packages, as-built drawings, maintenance manuals, permit records, and inspection reports for your property files.
OSHA Compliant
Full safety program, documented daily. Fall protection, hot-work permits, confined space protocols, and hazmat handling when needed.

Our Commercial Process
1. Consultation & Survey — We meet with building owners, property managers, or facility teams to understand requirements, timeline, and budget. Drone and infrared survey of existing conditions. Core samples taken to identify existing layers and insulation values.
2. Specification & Proposal — Engineered specification matching the right system to your building. Detailed proposal with scope of work, material specifications, timeline, phasing plan, and warranty details. We submit proposals within 5 business days of survey.
3. Pre-Construction — Permits, material ordering, HVAC coordination, tenant notification, and safety planning. Pre-construction meeting with all stakeholders to confirm schedule and access logistics.
4. Installation — Dedicated project superintendent on-site daily. Safety briefing every morning. Daily progress reports with photos to the building owner. Weather monitoring and contingency planning for every day of the project.
5. Closeout — Final inspection, leak testing, as-built documentation, warranty registration, and maintenance manual delivery. Post-installation walkthrough with the property manager. We're not done until the paperwork is as clean as the roof.

Frequently Asked Questions
Can you work nights and weekends to avoid disrupting our business?
Yes. We regularly schedule commercial roofing during off-hours. Retail centers get evening and overnight work. Office buildings get weekend installations. Warehouses with 24/7 operations get phased roof sections. We plan the schedule around your business, not ours.
Do you handle commercial roof maintenance contracts?
We maintain over 200 commercial roofs across the East Bay under annual service contracts. Quarterly inspections, drain clearing, minor repairs, and emergency response are included. Maintenance contracts typically cost 1-2% of roof replacement value annually and extend roof life by 30-50%.
What about HVAC equipment on the roof?
Rooftop units, ductwork, and their associated curbs, supports, and drains are integrated into every commercial roof plan. We coordinate with HVAC contractors for unit removal and reinstallation when needed. All equipment curbs are flashed to the same standard as the rest of the membrane system.
How do you handle phased replacements on occupied buildings?
Large commercial roofs are divided into sections. We complete one section at a time, fully weathering-in each section before starting the next. The building remains occupied and dry throughout. Phased replacement also spreads the capital expense over multiple budget cycles if needed.
Do you work with property management companies?
Over 40 East Bay property management firms use us as their roofing contractor. We provide annual inspection reports, maintenance documentation, capital planning budgets, and emergency response for their portfolios. Single point of contact for all properties under their management.

Call (925) 722-4916When We Turn Down Commercial Work
We're honest about our capacity. If your project needs specialty coatings (spray polyurethane foam), vegetated green roof systems over 20,000 sq ft, or work at heights requiring crane access, we'll connect you with a specialty commercial firm. We also won't compete on price by cutting material thickness or skipping details — if the cheapest bid is what you're after, we're not your contractor.
