Roof Coatings in Phoenix, AZ

Not every aging flat roof needs replacement. If the insulation is dry and the deck is sound, a properly applied coating system can restore waterproofing, improve energy performance, and add 15–20 years of service life for a fraction of replacement cost. The key word is 'properly' — a coating applied over wet insulation, unrepaired seams, or without adequate surface preparation will fail quickly and is not a solution. We perform a moisture scan and thorough seam inspection before recommending coating as an appropriate strategy.

We apply silicone coating systems as our default for Arizona flat roofs because silicone maintains its properties in standing water — which is nearly unavoidable on large flat roof sections during monsoon season. Acrylic coatings are excellent for sloped applications and have good UV reflectance but degrade under prolonged ponding. We match the coating chemistry to the specific conditions of your roof, not to what's easiest to apply.

Our coating process includes pressure washing, full seam and flashing reinforcement with fiberglass fabric, primer application, and two-coat finish application measured to the manufacturer's required wet mil thickness. We don't apply coatings in a single pass below specification — this is the most common cause of premature coating failure. All work is documented with mil gauge readings and photographic records.
