Commercial Roofing FAQ
Commercial roof questions
Can you work around our business hours?
We schedule commercial work to minimize disruption to your operations and tenants. Tell us your constraints and we’ll plan around them. Confirm scheduling
Do you repair commercial roofs or only replace them?
Both. When a targeted repair will solve the issue we’ll do that; when a roof is failing across the board we’ll quote a replacement.
What type of commercial roofing do you handle?
Primarily flat and low-slope membrane systems — see flat roofing for details.
