Silicone Roof Coatings: Premium Value for Your Roof

Protecting your home or commercial property from water damage and harsh weather in St. George, Utah starts with a good roofing solution. At St George Roof Coatings, we specialize in the best silicone roof coating systems—a cost-effective and durable solution that turns your existing roof into a seamless watertight barrier. Our silicone roof coatings typically outperform other roof coatings, such as acrylic coatings, modified bitumen, and elastomeric coatings, by preventing ponding water, lowering roof surface temperatures, and shielding against the sun’s harmful UV rays. Designed for flat roofs, metal roofs, and large roof structures, our silicone coating system extends roof life, reduces energy costs, and offers long-term protection against Southern Utah’s extreme temperatures and direct sunlight. Whether you’re a property owner or facility manager, our environmentally friendly silicone coatings provide a budget-friendly alternative to roof replacement, delivering benefits like reduced cooling costs and minimal maintenance.

Our advanced silicone roofing system, applied with high solids content for the desired dry mil thickness, creates an impermeable membrane that withstands wind-driven sand and heavy rainfall. Unlike other coatings, our modern silicone coating formulations resist airborne dust and particles, so your silicone-coated roof stays clean and functional for many years. By choosing St George Roof Coatings, you’re investing in a silicone coating system that increases energy efficiency, reduces internal building temperatures, and protects the roof from UV radiation and thermal movement.

This list explains why our silicone roof coatings work great for St. George’s desert climate and why they’re the best option for building owners seeking long-term performance without the high labor costs or disruption of a tear-off. For more information on how our coatings add years to your roof, read on to learn about our process and benefits.

Unmatched Durability: Our silicone coatings withstand St. George’s intense UV rays, heat, and harsh weather, lasting up to 20 years with proper maintenance, outperforming TPO or EPDM membranes that degrade faster in desert conditions.
Seamless Waterproofing: Unlike re-roofing or seamed membranes, our silicone forms a continuous, flexible barrier, preventing leaks and water pooling on flat or low-slope commercial roofs.
Cost-Effective Long-Term: At $4-$7/sq. ft., our silicone coatings save thousands compared to re-roofing (typically $8-$15/sq. ft., depending on materials), extending roof life without the disruption of a full replacement.
Energy Efficiency Boost: The reflective surface lowers rooftop temperatures by up to 50°F, cutting cooling costs by 10-20% in St. George’s hot summers, supported by industry standards.
Low Maintenance: Our silicone resists mold, mildew, and dirt buildup, requiring minimal upkeep compared to many new roofs or membranes, saving time and money.
Eco-Friendly Solution: Applied over existing roofs, our silicone avoids tear-offs and landfill waste, using low-VOC formulas for a sustainable choice that appeals to eco-conscious clients.
Versatile Application: Our silicone adheres to metal, TPO, EPDM, and concrete roofs, offering flexibility for St. George’s commercial and residential properties without costly substrate changes.
Superior UV Protection: The UV-resistant formula prevents cracking and degradation, unlike re-roofing materials or other coatings needing extra protective layers, ensuring long-term performance.
Quick Installation: Our silicone coatings are applied in days, minimizing disruption to your business or home compared to re-roofing’s lengthy construction process.
Manufacturer’s Long-Term Warranty: Our silicone coatings come with a manufacturer’s material warranty (up to decades, subject to conditions), complemented by St. George Roof Coatings’ 90-day application warranty, ensuring confidence in your investment.

Understanding Roofing Terms:

Silicone Roof Coatings: Liquid-applied membranes that cure into a seamless, flexible, waterproof layer, protecting roofs from UV rays, water, and weather while enhancing energy efficiency.
TPO (Thermoplastic Olefin): A single-ply roofing membrane known for its reflectivity and durability, commonly used on flat or low-slope commercial roofs but prone to seam leaks if improperly installed.

EPDM (Ethylene Propylene Diene Monomer): A synthetic rubber roofing membrane valued for flexibility and weather resistance, often used on low-slope roofs but less reflective than silicone or TPO.
Re-roofing: The process of removing an existing roof and installing a new one, typically more costly and disruptive than applying coatings.
Low-Slope Roof: A roof with a slight pitch (less than 3:12), common in commercial buildings, prone to water pooling without proper waterproofing.

*Performance claims, such as rooftop temperature reductions of up to 50°F and cooling cost savings of 10-20%, are based on industry standards and vary depending on factors like roof insulation, building type, HVAC efficiency, and maintenance. These figures represent maximum potential benefits under ideal conditions compared to dark, non-reflective roofs in St. George, Utah’s climate. St. George Roof Coatings provides a 90-day application warranty to ensure quality installation. The manufacturer’s material warranty (up to decades, subject to conditions) is provided by the coating manufacturer, not St. George Roof Coatings."
