It adheres to a variety of substrates, making it a strong all-around choice for aging or failing roofs that are structurally sound.
Who it’s best for: property owners managing mixed-roof portfolios or aging roofs that still have structural integrity. Why chosen: high reflectivity and primer-free adhesion in many cases. Caution: for EPDM surfaces, priming may still be required depending on specific conditions.
GacoFlex GacoRoof Gray Silicone Roof Coating
Best for silicone-based protection with a neutral gray finish. GacoFlex GacoRoof Gray is a silicone roof coating that offers broad substrate compatibility and durable weather resistance. It is suited to projects where silicone performance and a lighter, non-white color are desired.
Who it’s best for: owners needing a flexible, silicone-driven solution across multiple roof types. Why chosen: reliable silicone performance with a distinct gray color. Caution: verify substrate compatibility for premium performance on certain surfaces.
1 Gallon RV Roof Sealant White
This flexible liquid rubber sealant provides over 1000% elongation, making it suitable for sealing leaks and cracks on RV roofs. It is UV resistant (88% reflective) and bonds well to many surfaces, though EPDM may require a primer for best results. It’s a practical choice for DIY projects and professional work alike.
Who it’s best for: RV owners seeking a high-elongation, reflective sealant for leakage repair. Why chosen: excellent elongation and broad surface bonding. Caution: EPDM surfaces typically require primer for optimal adhesion.
Kool Seal KS0063600-20 Premium 10 Year Elastomeric Coating
Best for long-term protection with a 10-year warranty potential. Kool Seal Premium Elastomeric coating offers heat reflection and renews many roof substrates. It’s a versatile option for commercial buildings and other large-roof projects requiring durability and energy efficiency.
Who it’s best for: building owners and contractors seeking a durable, heat-reflective coating with a long-term outlook. Why chosen: strong warranty-oriented positioning and broad substrate compatibility. Caution: ensure proper surface preparation to maximize longevity.
Nationwide Coatings Mobile Home Roof Coating
Best for mobile home roofs needing elastomeric ceramic insulation. This 5-gallon option emphasizes energy efficiency and a reflective matte finish. It is designed to withstand high wind and weather, contributing to longer roof life in varied climates.
Who it’s best for: mobile home owners and managers looking to improve energy performance and weather resistance. Why chosen: ceramic heat-dissipating technology and strong weather performance. Caution: verify surface prep requirements and temperature guidelines for optimal curing.
TRP #911 Eternalastic Elastomeric Roof Coating
Best for professional-grade, energy-efficient protection. TRP #911 is an acrylic elastomeric roof coating that reduces roof temperatures and offers weather resistance. It is suitable for a variety of surfaces, following the manufacturer’s application guidelines.
Who it’s best for: contractors and property managers seeking a professional-grade solution with energy-saving benefits. Why chosen: durable acrylic formula and multi-surface compatibility. Caution: follow substrate-specific preparation and curing instructions for best results.
Marlin Coatings RV Roof Coating White
Best for RVs requiring a premium acrylic elastomeric waterproof sealant. Marlin Acrylic Top Coat aims to provide UV resistance, solar reflectivity, and a watertight membrane while allowing moisture to escape. It can be brushed, rolled, or sprayed.
Who it’s best for: RV owners needing an all-around, high-performance white top coat with good UV resistance. Why chosen: balanced features for durability and reflectivity. Caution: for proper cured thickness, apply multiple coats and avoid cooling temperatures during application.
Buying Guide
What roof surface do you want to coat? Identify whether you have EPDM, PVC, metal, granulated cap sheet, or built-up roofing. Some products work best with EPDM (such as Dicor’s coating), while others are more versatile across substrates (like silicone and elastomeric formulas).
Do you need heat reflectivity or energy savings? Silicone and elastomeric coatings with high reflectivity can reduce interior temperatures and energy costs. Consider color and reflectivity ratings when selecting a finish.
Is primer required? Some products claim primer-free adhesion on common substrates, while others may need surface preparation for optimal bonding. Verify substrate compatibility and follow manufacturer guidance.
What scale and roof type are you coating? For large commercial roofs, durability and a longer warranty window can justify higher upfront costs. For RV roofs, ensure compatibility with EPDM and consider flexibility and UV resistance.
Application method and equipment: many products can be brushed, rolled, or sprayed. Assess your available tools, crew capability, and climate when planning application windows. Some coatings cure faster in warmer, drier conditions.
FAQ
- Which coating is best for EPDM RV roofs? Dicor RP-CRC-1 is specifically designed for retrofit protection of EPDM membranes used on RV roofs, offering compatibility and a white finish for heat management.
- Do I need a primer for silicone roof coatings? Many Countryman Coatings Silicone Top Coat formulations claim no primer is required in most situations, but EPDM surfaces may still need primers per substrate guidelines.
- Can silicone coatings be used on metal roofs? Yes, silicone top coats like Countryman Coatings and others are designed for a broad range of substrates, including metal, with proper surface preparation.
- How long do elastomeric roof coatings typically last? Premium elastomeric coatings, such as Kool Seal and Marlin Coatings, are designed for multi-year protection, with performance depending on climate, installation, and maintenance.
- Are white coatings better for heat reflection? White and light-colored coatings reflect more UV radiation, potentially lowering interior temperatures and energy use compared with darker coatings.
- Should I apply coatings to aging roofs? If the roof is structurally sound but aging, high-reflectivity coatings can extend life. Address any leaks or damage before coating for best results.
