What Is a Cool Roof System? How ASC Coatings Can Extend Your Roof's Life

Replacing a commercial or flat roof costs $8–$15 per square foot. Coating it with American Standard Coatings (ASC) reflective system costs $3–$6 per square foot — and extends your roof's life by 10–15 years. Here's how cool roof technology works.

What Is a Cool Roof?

A cool roof is a roofing system designed to reflect more sunlight and absorb less heat than a standard roof. It typically uses high-albedo (reflective) coatings, membranes, or shingles to keep building interiors cooler — reducing AC load and energy costs.

How ASC Coatings Work

American Standard Coatings produces premium silicone, acrylic, and urethane roof coatings that bond directly to your existing roof. Once applied, they form a seamless, monolithic membrane that:
- Reflects up to 85% of UV radiation
- Lowers rooftop temperature by 50–70°F on hot days
- Seals seams, cracks, and minor punctures
- Provides waterproof protection without removing the existing roof

Energy Savings

Cool roof coatings reduce cooling costs by 10–25% in commercial buildings. For a 20,000 sq ft warehouse, that's typically $3,000–$8,000 in annual savings — paying back the coating investment in 4–7 years on energy savings alone.

Why Coating Beats Replacement

1. Cost — typically 50–70% less than tear-off and replacement.
2. No business interruption — applied while you operate.
3. No tear-off waste — environmentally friendly and avoids landfill fees.
4. Tax benefits — coating is often a tax-deductible maintenance expense, while replacement is depreciated over 39 years.
5. Energy Star certified — qualifies for utility rebates in many areas.

When Coating Is the Right Choice

Coating is ideal when: your roof is structurally sound but aging, you have a flat or low-slope commercial roof, you're seeing minor leaks or seam failures, energy bills are climbing, or you want to extend your roof's life by 10+ years.

When to Replace Instead

If decking is rotted, the roof has multiple major leaks, insulation is saturated, or the existing membrane is severely deteriorated — replacement is the better long-term call.
