Roof Coatings

Extend the life of your commercial roof and slash energy costs with professional reflective coatings. Reduce surface temperatures by up to 80°F without replacing your existing roof system.

A Cost-Effective Alternative to Full Roof Replacement

Roof coatings are liquid-applied membranes that form a seamless, monolithic protective layer over your existing commercial roof. When applied to a structurally sound substrate, a quality coating system can add 10–20 years of service life at a fraction of the cost of full replacement.

In Arizona's extreme UV environment, reflective roof coatings are especially impactful. A white, highly reflective coating can reduce roof surface temperatures from 170°F down to 90°F — directly reducing the heat load on your building and cutting cooling costs significantly.

  • Reduces roof surface temperature by up to 80°F
  • Extends existing roof life by 10–20 years
  • 50–70% less expensive than full roof replacement
  • No tear-off — minimal disruption to your operations
  • Seamless membrane eliminates seam-related leaks

Coating Types We Install

We select the right coating system for your specific roof type, substrate condition, and performance goals.

Elastomeric Roof Coatings

Elastomeric coatings are water-based acrylic systems that stretch and recover with temperature fluctuations — critical in Arizona where roofs expand and contract significantly between summer days and cool nights. These coatings provide excellent UV resistance, good adhesion to most substrates, and are environmentally friendly due to their low VOC content.

  • Excellent UV and weathering resistance
  • High flexibility — won't crack under thermal cycling
  • Low VOC — water-based, environmentally friendly
  • Compatible with built-up, modified bitumen & single-ply

Silicone Roof Coatings

Silicone coatings offer premium performance, especially in ponding water situations. Unlike acrylic coatings which can soften or re-emulsify under standing water, silicone maintains its integrity even when submerged. This makes silicone the preferred choice for flat commercial roofs with less-than-ideal drainage and for Arizona's monsoon season ponding risks.

  • Best-in-class ponding water resistance
  • Exceptional UV stability — won't chalk or degrade
  • Ideal for foam roof re-coating applications
  • Single-coat application possible in some cases

Foam Roof Re-Coating

If your building has an existing spray polyurethane foam roof with a worn or thin top coating, re-coating is the most cost-effective option — far less expensive than a full tear-off and replacement. We inspect the existing foam for damage, repair any problem areas, and apply a new silicone or elastomeric top coat to restore your roof to like-new condition.

  • Restores worn foam roof coating to like-new condition
  • Fraction of the cost of replacement
  • Foam repairs performed before new coating applied
  • Renews the roof's reflectivity and energy performance

Preventive Maintenance & Annual Care

A proactive maintenance program is the single best investment you can make to extend your commercial roof's lifespan and avoid costly emergency repairs.

Annual Maintenance Program

Our annual maintenance program includes scheduled bi-annual inspections (spring and fall), minor repairs as needed, detailed inspection reports with photographs, and priority scheduling for any emergency calls. Regular maintenance protects your warranty and catches problems before they become expensive repairs.

Pre-Monsoon Inspections

Arizona's monsoon season brings intense rain, strong winds, and flying debris that can damage even well-maintained roofs. Our pre-monsoon inspection identifies and repairs any vulnerabilities before storm season arrives — protecting your property and your tenants.

Inspection Reports

After every inspection we provide a comprehensive written report with photographs documenting your roof's condition, any areas of concern, work performed, and recommended future actions. This documentation is invaluable for insurance claims and capital planning.

Multi-Property Programs

For property managers and REITs with multiple commercial buildings, we offer consolidated maintenance programs with unified reporting and preferential pricing. One point of contact for all your Arizona commercial roofing needs.

Roof Coating Questions

The best candidates for roof coating are roofs with a structurally sound deck and membrane that have surface deterioration but no active leaks or significant moisture in the insulation. We assess this during a free inspection using moisture testing and a thorough visual evaluation. If the existing roof is saturated with moisture, coating over it will trap that moisture and accelerate deterioration — in that case, replacement sections may be needed first.
Quality roof coatings in Arizona typically last 10–15 years when properly applied and maintained. Arizona's intense UV radiation and thermal cycling are harder on coatings than many other climates, so we specify premium coating products rated for our environment. Regular maintenance inspections help ensure the coating performs for its full rated life.
Yes, though we carefully manage application conditions. Water-based elastomeric coatings require surface temperatures between 50°F and 130°F and must be applied when no rain is expected for 24 hours. We schedule early morning applications during the hottest months to meet these conditions. Solvent-based and silicone coatings have different requirements — we'll recommend the right system and schedule for your project timeline.
Proper surface preparation is critical to coating adhesion and longevity. We pressure wash the roof, repair any blisters, splits, or failed flashing, prime the substrate if required, and allow the surface to dry completely. Skipping preparation steps is the leading cause of premature coating failure — we never cut corners on prep work.
