Commercial roof coatings

Overview

A waterproof roof coating over the roof you have

A roof leak rarely starts big. A seam opens or a small crack forms, water gets in, and over time it rusts the deck and weakens the structure long before anyone sees a stain inside. A commercial roof coating seals the whole surface, small holes and cracks included, without tearing the roof off.

We coat aging metal roofs, asphalt roofs, and rubber-based roofing systems on warehouses, plants, offices, and retail buildings.

Elastomeric roof coatings

We specialize in elastomeric roof coatings. It’s a synthetic rubber coating applied over the existing roof. It stretches and shrinks with the roof through hot days and cold nights, bridges small cracks and holes, and keeps the whole surface watertight. Where the roof takes a lot of sun, a UV-protective urethane or clear topcoat goes over it to keep it from breaking down and fading.

Cool roof coatings

On a hot day a dark roof can get well above 100 degrees, and that heat goes straight into the building. A reflective cool roof coating, usually white or silver, sends the sun’s heat back. The roof runs cooler, the air conditioning works less, and cooling costs come down.

Repairs come first

A coating over a problem doesn’t fix it. Open seams, holes, cracks, and low spots where water ponds get repaired first. Then the roof is pressure washed to get dirt, grime, and oil off before the coating goes on.

On a CBRE-managed building in Beverly Hills, water was getting in through the roof. We leveled the low spots with fiberglass mesh set in epoxy so water would stop pooling, then put down multiple coats of elastomeric and a UV-protective urethane topcoat across the roof, the parapet walls, and the flashing caps.

Other roof systems

Not every roof is a fit for elastomeric, and our crew checks yours on the site visit. Where another system works better, we’ll recommend it. Acrylic adds UV protection and is common over sprayed foam roofs, with a sealer to make it waterproof. Silicone holds up very well to sun but costs more. Rubberized coatings go over many roofing membranes.
