FAQ
Common Questions About Commercial Roofing
Have questions about your commercial roofing project? We’ve compiled answers to the most common queries from property owners and facilities managers — or reach out directly and we’ll respond the same business day.
Still have questions?
Our commercial team is available Monday–Friday, 8am–6pm. We're happy to discuss your property's specific requirements before you make any decisions.
How long does a commercial roof replacement take?
Commercial roofing timelines depend on the size of the building, the roofing system being installed, and site access conditions. A standard 10,000–20,000 sq ft commercial re-roof typically takes 3–7 business days. Larger industrial or multi-building projects are planned with detailed schedules to minimize business disruption. We’ll provide a specific timeline during your proposal phase.
Which flat roofing system is best for my commercial property?
The right system depends on your building’s structural load capacity, budget, climate, rooftop equipment traffic, and desired lifespan. TPO is popular for energy efficiency and cost-effectiveness. EPDM offers proven durability across all climates. Modified bitumen and BUR systems are ideal for high-traffic rooftops. Our commercial estimators evaluate all factors and recommend the most appropriate system for your specific property during the site assessment.
Do you work on occupied commercial buildings?
Yes — the majority of our commercial projects are completed on occupied buildings. Our crews are OSHA-certified and trained to work safely around employees, tenants, and customers. We develop detailed safety plans for each project, establish controlled work zones, and schedule the most disruptive work during off-hours or weekends where required. Your operations continue with minimal interruption.
What warranties do you provide on commercial roofing work?
Every commercial project includes our workmanship warranty covering the quality of installation, plus manufacturer system warranties on all materials — ranging from 15 years on standard single-ply membrane systems to 30 years on premium commercial systems. For qualifying projects, we can also register manufacturer NDL (No Dollar Limit) warranties that cover both materials and labor. Full warranty documentation is provided at project completion.
Can you work directly with our insurance company for storm damage claims?
Yes. Our commercial team is experienced in working alongside insurance adjusters and risk managers for storm damage claims. We provide detailed written damage assessments, photographic documentation, and scope-of-work reports in the formats required by commercial insurance carriers. We work to ensure your claim accurately reflects all storm-related damage identified during our inspection.
Do you offer ongoing maintenance contracts for commercial properties?
Yes. Our Commercial Preventative Maintenance Program provides structured annual or semi-annual inspections, detailed written condition reports, priority service response, and discounted repair rates for enrolled properties. Proactive maintenance is the single most cost-effective way to extend the life of your commercial roof and avoid unexpected emergency repair costs.
