Commercial Flat Roofing

Your flat roofing questions, answered.

Helpful answers for Bay Area business owners and property managers.

Is modified bitumen roofing right for my building?

Modified bitumen is an asphalt-based membrane option for commercial low-slope roofs. Whether it fits depends on your roof's condition, layout and budget, and we'll help you weigh it.

How are drainage and roof penetrations addressed?

We look at how water flows across your roof, where the drains sit, and how vents, equipment and other penetrations are flashed, then plan the details around them.

Can work be coordinated around business hours?

We plan the work around your site access, tenants and operations. Tell us your constraints up front and we'll build them into the schedule.

What maintenance will my roof need?

Routine inspections help identify wear and developing issues early. We'll explain what to check and how often for your specific roof.
