High Performance Silicone Coatings: A Durable Roof Solution

When it comes to commercial roof restoration in St. George, UT, choosing the right roof coating is key to durability, energy efficiency and cost savings. At St. George Roof Coatings we specialize in high-performance silicone coatings, specifically high solids silicone coatings with an epoxy primer for maximum adhesion and performance. While options like acrylic, polyurethane, spray polyurethane foam, seamless membrane systems and asphaltic rubber membranes are available, silicone roof coating stands out for its weatherability and ability to withstand temperature extremes, UV rays and moisture. Applied directly to substrates like concrete, metal, asphalt, PVC or single-ply membranes our high solids silicone is compatible with a wide range of roof substrates including modified bitumen so it’s versatile and adheres well to various roofing materials.

Proper surface preparation is key before application; all dirt and debris must be removed from the roof for optimal adhesion and durability. The epoxy primer enhances adhesion and the coating material must be mixed with a drill mixer before application. Mixing the material is crucial for optimal performance and long term results.

Silicone coatings can be applied with several methods including roller, brush and roll. A roller or brush is great for detailed or smaller areas for precise coverage and adhesion. With advanced spray equipment our experienced team applies these systems with attention to detail including sealing around parapet walls and making sure all seams are covered for a complete waterproof barrier.

Our high solids silicone creates a seamless, waterproof membrane that seals the existing roof eliminating the need for costly roof replacement and reducing landfill waste. The coating forms a durable, seamless membrane that will protect for years to come.

The epoxy primer enhances adhesion, a VOC compliant coating that resists ponding water and has impact resistance. Property owners get a new warranty and a high performance solution that protects against the elements for long term results. Cure time for the coating may vary depending on atmospheric conditions and one coat can provide the required durability and weather resistance.

Why Silicone Roof Coatings Excel:

• Superior Water-Shedding: Silicone coatings are exceptionally resistant to ponding water, a common challenge on flat or low-slope commercial roofs. Their moisture cure properties ensure excellent weatherability, even under prolonged exposure to harsh conditions. Silicone coatings help prevent leaks caused by ponding water and harsh weather.

• UV Protection: These coatings provide outstanding defense against UV rays, making them ideal for the intense sunlight and temperature extremes of Southern Utah. The 100% silicone roof system reflects solar heat effectively, and its high solar reflectance helps reduce heat absorption.

• Longevity and Durability: Silicone coatings maintain flexibility and excellent adhesion over time, offering long-term protection without becoming brittle, even on existing roof surfaces exposed to the elements. The coating is designed to seal around seams and penetrations, preventing water ingress.

• Energy Efficiency: With high reflectivity and emissivity, the reflective properties of high solids silicone reduce heat absorption, lowering cooling costs and enhancing indoor comfort—crucial for energy savings in hot climates.

Silicone coatings are resistant to rain and snow, maintaining their performance even under extreme weather. Performance and cure time can vary depending on atmospheric conditions such as temperature and humidity. Properly sealing seams is essential to ensure a watertight finish.

The Epoxy Primer Advantage:

Prior to applying the primer, it is essential to perform thorough surface preparation and adhesion testing to ensure optimal results. Certain areas, such as those subject to frequent water exposure or heavy foot traffic, may require additional attention during preparation.

• Enhanced Surface Preparation: The epoxy primer levels out surface irregularities on single ply membranes or existing roof systems, ensuring the substrate is properly prepared for optimal adhesion and that the silicone coating adheres perfectly with excellent adhesion.

• Increased Durability and a More Durable Finish: It strengthens the bond between the roof and the 100% silicone roof layer, withstanding temperature extremes and harsh weather for a robust, long-lasting finish.

• Extended Roof Life: The combination of epoxy primer and high solids silicone forms a resilient system that can significantly prolong your roof’s lifespan, reducing landfill waste by avoiding premature replacements.

Silicone vs. Other Coating Options:

• Acrylic Coatings: Cost-effective and reflective, but they struggle with ponding water and harsh weathering, requiring specific climates and surface temperatures for curing.

• Polyurethane Coatings: Known for impact resistance, these require multiple layers applied with spray equipment or a spray gun, increasing labor and expense compared to a single component silicone system.

• Asphaltic Rubber Membranes: Useful for repairs but not ideal as a primary coating due to limited versatility and specific application needs.

Compared to other roof coatings, silicone coatings stand out for their superior performance and durability.

In contrast, silicone coatings with an epoxy primer offer a complete solution—waterproofing, UV resistance, and durability—in one efficient application, outperforming alternatives like spray polyurethane foam or traditional roof membranes. Silicone coatings are also ideal for restoration projects and can be applied to a wide range of roofing systems, improving existing roofs and extending their lifespan. Many silicone coating systems come with extended warranties, providing long-term reliability and peace of mind.
