Note: All products are designed to work with common RV roof substrates and offer solar reflectivity to reduce interior temperatures. Always follow surface preparation steps and consider primer requirements for EPDM surfaces when applicable.
Liquid Rubber RV Roof Sealant — 1 Gallon
Best for: Small to mid-size RVs, DIY enthusiasts seeking a reliable, flexible membrane. This professional-grade sealant forms a durable, water-tight layer and offers heat-reflective properties to keep interior temperatures lower. Selected for its multi-surface compatibility (EPDM, TPO, fiberglass, aluminum) and compatibility with Liquid Rubber EPDM Primer for enhanced adhesion on EPDM surfaces. Caution: For EPDM surfaces, primer use can improve bond strength.
Liquid Rubber RV Roof Sealant — 5 Gallon
Best for: Owners planning larger area coverage or ongoing RV upgrades. The 5-gallon option delivers the same flexible, water-resistant membrane with heat reflectivity, enabling cost-effective roof protection for bigger travel trailers and motorhomes. Recommended to pair with the EPDM Primer when working on EPDM surfaces to optimize adhesion. Caution: Ensure even coverage to achieve consistent reflectivity and leak protection.
Liquid Rubber EPDM and TPO Primer
Best for: RV owners preparing EPDM or TPO roofs for coating. The primer boosts adhesion on EPDM and enhances the overall performance of subsequent coatings. Choose this if your roof is aging or has prior coatings that require a strong bonding base. Caution: Not a stand-alone sealant; must be used before applying compatible RV roof coatings on EPDM surfaces.
BEEST RV Roof Coating White — 1 Gallon
Best for: RVs needing flexible, UV-stable protection with broad surface compatibility. BEEST is noted for its high-coverage performance and suitability for trailers, campers, and homes alike. It pairs well with BEEST Roof Cleaner & Primer for EPDM surfaces. Caution: Two coats are often recommended to achieve maximum water sealing on variable roof textures.
1 Gallon RV Roof Sealant — White (Tenee)
Best for: DIYers seeking a flexible, white, solar-reflective coating with high elongation. The product claims 1000% elongation, with strong adhesion to multiple substrates and no primer required in many cases. Use with appropriate surface preparation for best results. Caution: EPDM surfaces may require primer to maximize adhesion in some installations.
Kohree RV Roof Coating — 1 Gallon
Best for: Consumers seeking a 100% silicone, no-primer-required solution with strong heat-reflective properties. Kohree provides elasticity and waterproof sealing on EPDM, TPO, metal, fiberglass, and more, with straightforward application. Caution: Silicone coatings can be less paintable if you plan future color changes or repairs; plan maintenance accordingly.
Buying Guide
What roof materials are compatible?
Look for coatings labeled as compatible with EPDM, TPO, fiberglass, and aluminum. Many products list cross-compatibility across these substrates, making them versatile for most RV roofs.
Do I need a primer?
EPDM roofs often benefit from a primer to maximize adhesion, especially when applying a silicone or elastomeric coating. Check product data for primer requirements and consider an EPDM primer if your roof is aged or has irregular textures.
What about coverage and coats?
Most products cover about 50 sq ft per gallon per coat. For best results on flat to moderately curved roofs, two coats are common. Larger RVs may justify a 5-gallon purchase for cost efficiency and fewer refill breaks.
Is silicone or water-based better?
Silicone coatings tend to offer excellent elasticity and long-term waterproofing, with high UV resistance. Water-based elastomeric coatings are lower in odor and VOCs and are easier to clean up, making them family-friendly and eco-conscious choices.
Solar reflectivity and energy savings
Many products advertise solar reflectivity to reduce interior temperatures. While this can lower cooling costs, the degree of savings depends on climate, roof color, and roof condition. Choose coatings with high reflectivity ratings for hotter climates.
Application tips
- Clean and dry the roof before applying any coating.
- Repair any structural issues or severe damage prior to coating.
- Use a brush, roller, or sprayer appropriate for the coating’s viscosity.
- Avoid applying during extreme temperatures or wet conditions.
Maintenance considerations
Inspect coatings annually for cracks or peeling. Prompt repair of small defects prevents larger leaks. Recoat when the film shows signs of wear or after several seasons, depending on climate exposure.

Frequently Asked Questions
- Can these coatings be used on metal roofs? Yes, most are compatible with metal in addition to EPDM and TPO.
- Do I need to remove old coatings before applying a new layer? It depends on condition; clean and repair as needed, and prime where required.
- Will coating prevent leaks permanently? Coatings provide a watertight seal when properly applied, but regular inspection and maintenance are essential.
- Are these coatings safe for the environment? Many are water-based or low-VOC; verify product specifications for your preferred option.
- How long does a coating last? Lifespan varies by climate, roof condition, and maintenance, but periodic re-coating extends roof life.
- Do coatings affect interior temperature significantly? Solar-reflective coatings can help reduce interior heat in hot climates, contributing to energy savings.
