Living in Southern Utah, especially in St. George and Cedar City, puts your RV in extreme heat, intense UV rays and occasional heavy storms, making it tough to keep your roof in shape. St. George summer temperatures often hit 100°F and Cedar City’s climate is cooler but unpredictable, your RV roof takes a beating that can compromise its integrity. At St George Roof Coatings we specialize in custom roof coatings to protect your RV and extend its life in these harsh conditions. We use premium products like Lanco Coolguard, Dicor and Geocel to provide long lasting RV roof coatings in Southern Utah. This article will explain why custom RV roof coatings matter, our process at St George Roof Coatings and how our custom solutions keep your RV in top shape no matter the situation in St. George or Cedar City.
Why RV Roof Coatings Are Essential in Southern Utah

RV roof coatings act as a protective barrier, shielding your vehicle from weather-related damage. In St. George, where UV exposure is relentless and temperatures can hit 117°F, coatings prevent cracking, fading, and leaks. In Cedar City, where snow and cooler temperatures add stress, coatings maintain roof integrity. Benefits include:
Weather Protection: A waterproof seal guards against rain, snow, and UV damage.
Energy Efficiency: Reflective coatings like Lanco Coolguard reduce heat absorption, keeping your RV cooler.
Extended Roof Life: Coatings prevent deterioration, delaying costly replacements.
Cost-Effective Maintenance: Regular coatings are more affordable than full roof repairs.
Types of RV Roof Coatings
RV roofs come in various materials, each requiring specific coatings:
EPDM (Ethylene Propylene Diene Monomer): A rubber-like material common in RV roofs, needing primers for adhesion.
TPO (Thermoplastic Olefin): A durable, single-ply membrane that benefits from primers for elastomeric coatings.
Metal Roofs: Often found on older RVs, requiring corrosion-resistant coatings.
Fiberglass Roofs: Less common but needing specialized sealants for flexibility.
At St George Roof Coatings, we tailor our approach to your RV’s roof type, ensuring optimal protection with products like Lanco Coolguard for EPDM and TPO roofs.
Our Expert RV Roof Coating Process

At St George Roof Coatings, we follow a meticulous process to ensure your RV roof is protected and durable. Here’s how we do it:
Remove Old Caulking: We start by carefully removing old, cracked, or failing caulk around vents, skylights, and seams to create a clean surface for new sealants.
Remove Loose Material: Any loose debris, dirt, or flaking material is cleaned off to ensure a smooth, stable surface for coating application.
Prime Bare EPDM or TPO Roofs: For bare EPDM or TPO roofs, we apply Lanco Aqua-Proof primer to enhance adhesion of the top coat, critical for long-lasting protection in Southern Utah’s climate.
Patch Bare Areas: If the roof is mostly coated but has exposed areas, we use Lanco 1 Gal. Siliconizer White Elastomeric Crack Filler Smooth Knife Grade for permanent, water-resistant patching. This ensures a seamless surface.
Caulk Around Roof Seals: We apply Dicor 501LSW-1 RV Rubber Roof Sealant Self Leveling Caulk around vents, skylights, and other roof seals to create a watertight barrier.
Caulk Windows and Doors: For seals around windows and doors on the sides of the RV, we use Geocel 28101V Pro Flex White RV Flexible Sealant, designed for flexibility and durability.
Repair Seams with Eternabond: Areas breaking away at seams are reinforced with Eternabond RoofSeal Repair Tape, providing a permanent, waterproof seal.
Apply Top Coat: Finally, we coat the entire roof with Lanco Coolguard 5 Gal. Insulating Elastomeric White Roof Sealer. This reflective, durable top coat protects against UV rays, heat, and weather, extending your roof’s life.
This process ensures your RV roof is fully protected, with every step tailored to address Southern Utah’s unique environmental challenges.
