Roof Coatings

Add years to your roof,
not a new roof bill.

Reflective silicone and acrylic coatings that seal an aging flat roof, knock down summer heat, and put off replacement for years — at a fraction of the cost.

What a coating actually does

A roof coating is a seamless, fully-adhered membrane applied over your existing flat roof. It seals hairline cracks and seams, waterproofs the field, and reflects sunlight instead of soaking it in. On a black DC rowhouse roof that bakes all summer, a white reflective coating can drop rooftop temperatures dramatically — your top floor feels it, and so does your cooling bill.

Done at the right time, a coating adds ten or more years of life to a structurally sound roof.

When coating makes sense — and when it doesn't

Coatings are for roofs that are aging but not failed. If your membrane is dry, cracking at the seams, or chalking but the deck underneath is solid, a coating is the smart money. If there's saturated insulation, widespread ponding, or rot below, coating over it just buries the problem — we'll tell you, with photos.

That honesty is the whole point of hiring a family company: we quote what the roof needs, not what pays best.

Prep is most of the job

Anyone can roll coating. The work is in the prep: power-washing the field, cutting out and patching failed seams, re-securing flashings, and priming where the system calls for it. We do the prep right so the coating bonds and the warranty means something.

Roof Coatings questions, answered

A properly prepped silicone or acrylic coating typically lasts 10 to 20 years depending on the product and the roof's condition, and many systems can be recoated to extend that again.
Yes — both, with the right primer and product match. We confirm the existing membrane and its condition first, because adhesion is everything with coatings.
A coating seals minor seam cracks and pinholes, but active leaks need to be traced and repaired first. We fix the source, then coat the field so it doesn't come back.
