Elastomeric coats are a revolutionary roof coating solution that provides superior protection and longevity for all types of roof surfaces. These single-ply liquid-applied coatings form a seamless, flexible membrane that can extend the life of a roof by 15-20 years or more. Elastomeric coats offer a cost-effective alternative to roof replacement that is quick and easy to install.

Composition and Properties

Elastomeric coats are acrylic-based coatings that are liquid at room temperature but cure to form durable, rubber-like solids. They are comprised of elastomeric polymers, inert minerals, and various additives that enhance performance.

The unique Elastomeric Coatings of elastomeric coats provide superior flexibility and longevity compared to other roof coatings. They can stretch over 300% without degradation and return to original form, allowing the coating to flex with roof movement caused by thermal expansion and contraction. This flexing action prevents cracking or alligatoring that is common in non-elastic coatings over time.

Elastomeric coats also have excellent adhesion to most roof surfaces like BUR, single-ply, metal and concrete. They form an extremely durable membrane with puncture and tear resistance to withstand foot and hail impacts. The cured membrane is highly waterproof, insulating, and resistant to ultraviolet radiation, ozone, and mold/mildew growth.

Installation and Application

Installing an elastomeric coating system is a straightforward process that typically takes 1-3 days to complete for an average-sized roof. Professional applicators use airless sprayers or rollers to apply two or more basecoats of the elastomeric coating, followed by a reflective white topcoat.

Prior to installation, the roof surface must be properly prepared by power washing, patching cracks/holes, and allowing to fully dry. Primers are often used to promote adhesion on difficult surfaces. The elastomeric coating is applied in perpendicular passes at a rate of 1.25-1.5 gallons per 100 square feet for the basecoats.

The topcoat further protects the base membrane and helps reflect solar radiation for energy efficiency and cooler interior temperatures. Application during suitable weather conditions ensures proper curing. Roof warranty options starting at 10-15 years can be obtained through the manufacturer.

Best Applications

Low-sloped roofs: Elastomeric coats are especially effective for low-slope and flat roofs that have traditional drainage issues. The seamless flexible membrane sheds water perfectly to prevent roof leakage problems.

Metal roofs: They protect corrosion-prone metal surfaces from the elements and reflect UV rays to extend the life of standing seam or rib metal panels.

Aged/distressed roofs: When roof replacement is cost-prohibitive, elastomeric coats can restore and waterproof worn single-ply, BUR, or modified bitumen membranes.

Green roofs: The flexible coating enables installation of intensive and extensive green roofs by waterproofing the roof deck beneath the growing media.

Elastomeric Coatings Benefits Over Other Options

Compared to replacing an entire roof, elastomeric coats provide:

- Lower total project cost due to minimal surface preparation needs and quick installation time. Replacement often costs 2-3 times as much.

- Less disruptions to occupants since the existing roof structure is left fully intact. No heavy tear-off and disposal required.

- Improved sustainability from diverting construction waste from landfills and conserving raw material usage.

- Potential energy savings through enhanced insulation, reflectivity, and longer roof service life span.

- Fewer waste and emissions compared to intensive replacement projects and extended membrane performance.

- Optional cool roof certifications provide reflective and emissive benefits in reducing the urban heat island effect.

ROI Considerations

While elastomeric roof coatings require upfront costs, they provide an excellent return on investment through long-lasting repairs and protection. By extending a roof's life by over a decade, the annualized costs are markedly lower than replacement costs amortized over a typical 20-30 year roof lifespan. Factor in labor and disposal cost avoids along with potential energy savings, and elastomeric coats deliver great financial savings and environmental benefits compared to full replacement.



As a cost-effective, sustainable, and high-performing liquid roofing solution, elastomeric coats have revolutionized roof maintenance and restoration projects. Their elastic properties provide unmatched flexibility and weather resistance compared to other coatings. Elastomeric technology has enabled roof surfaces to be waterproofed, protected and extended for 15-20+ years with a minimal cost investment. For commercial buildings seeking predictable long-term roof asset management, elastomeric coats have become the solution of choice.
