About commercial roofing

Commercial roofing covers shops, offices, warehouses and apartment buildings: mostly flat or low-slope roofs with single-ply membranes, metal, or built-up roofing, plus the rooftop units and drains that go with them. The work runs around a business that must stay open, so the schedule, safety plan and insurance certificate matter as much as the roof itself. Ask for references from similar buildings.

What to ask a contractor

  • Can you work around our hours, and how will you protect the building and the people in it?
  • Which system do you recommend, and what is its rated life?
  • Do you carry commercial liability and workers’ compensation insurance, and can I see the certificates?
  • Can you give references from buildings like ours?
