Commercial Roof Coating FAQ

Answers to the questions building owners and property managers ask us most about silicone and elastomeric roof restoration.

How much can a roof restoration save compared with a replacement?

A restoration typically costs a third or more less than a conventional roof replacement, because there is no tear-off and most rooftop equipment does not have to be moved. Your exact savings depend on the roof's size and condition.

How long does a roof coating last?

It depends on the system and the thickness applied. Silicone restoration systems can carry manufacturer leak warranties up to 20 years and material warranties up to 50 years on qualifying roofs, and many can be recoated at the end of their service life.

Can you coat over my existing roof?

Usually, yes. Coatings can go over most EPDM, TPO, PVC, modified bitumen, built-up and metal roofs, as long as the deck is solid. Any wet insulation is removed and replaced before coating.

How do you know if my insulation is wet?

During the roof assessment we look for signs of trapped moisture and, where needed, take core samples. Wet areas are marked, removed and replaced as part of the restoration.

How long does a restoration take?

Some restorations are completed in as little as two days. Larger roofs or roofs that need more repairs take longer. We will give you a schedule with your proposal.

Will my business have to close during the work?

No. There is no tear-off, so the building stays open and occupants are not exposed to an open roof.

Do I have to move my rooftop units?

In most cases, no. Most rooftop units, cell tower equipment and other fixtures stay in place during a restoration, which can save tens of thousands of dollars compared with a replacement.

Is a roof coating warrantied?

Yes. We install manufacturer-warranted systems from companies including GAF, Gaco, APOC, Henry and Lucas. Warranty terms depend on the system, thickness and roof condition, and are spelled out in your proposal.
