Phoenix Commercial Reroofing

Commercial Roof Replacement in Phoenix, AZ

Tear-off or recover, deck repair and a new roof system planned around your tenants.

Replacing a Commercial Roof in Phoenix

A roof reaches replacement when repairs and recoats stop paying off: widespread wet insulation, a deck that is rusting or soft, or leaks in many places at once. A moisture survey and a few core samples show you how much of the roof is still sound.

Replacement can mean a full tear-off down to the deck, or a recover over the existing roof where it is dry and code allows. We explain which fits your building and what each means for cost, schedule and the next roof after this one.

Reroofing a commercial building in Phoenix goes through the City's Planning & Development Department. The City's reroofing permit application asks whether the job is a tear-off or a recover, the roof slope, whether the roof drains through drains or scuppers, the UL class rating of the new membrane assembly, and whether any electrical, plumbing, gas or HVAC work is being relocated or replaced. We gather those details during the assessment, handle the permit when the work needs one, and confirm current requirements with Planning & Development (602-262-7811).

Commercial Roof Replacement Questions

How long does a commercial roof replacement take?

It depends on roof size, tear-off and weather. We give you a schedule with the scope and work in sections so the building is watertight at the end of every day.

Do we need a permit to replace a commercial roof in Phoenix?

Reroofing goes through the City of Phoenix Planning & Development Department. We confirm what your project needs and handle the permit when required.

Can tenants stay open during a reroof?

Usually, yes. We plan noisy tear-off, crane lifts and odorous work around business hours and give you notices to share with tenants.

Can we spread a replacement across budget years?

Often. On larger buildings or multi-building properties we can phase the work by section and repair the rest to hold until the next phase.
