Protect and maintain your RV roof with Kohree Waterproof RV Roof Coating. Made with a white, 100% silicone formula, this flexible, rubberized coating reflects sunlight to help reduce heat absorption while providing a waterproofing layer for compatible RV roof surfaces. It is designed for EPDM, TPO, metal, wood, fiberglass, and aluminum roofs.

No primer is needed on compatible surfaces, but proper cleaning, seam preparation, and suitable weather conditions are essential for a successful application.

  • Flexible, Heat-Reflective Protection: This white RV roof coating forms a durable rubberized surface that reflects sunlight and reduces heat absorption. Its advanced UV-resistant formula shields your RV roof from cracking, fading, and sun damage—helping lower interior temperatures and extend your roof’s lifespan.
  • Versatile for Multiple Surfaces: Engineered with a 100% pure silicone formula, our waterproof RV coating offers superior elasticity, breathability, and long-lasting waterproof protection. It adheres seamlessly to EPDM rubber, TPO, metal, wood, and fiberglass, creating a permanent weatherproof barrier. Ideal for RV campers, trailers, motorhomes, and mobile homes, it ensures effortless RV roof repair that lasts.
  • No Primer Needed – Easy DIY Application: Skip the complicated prep work—simply clean your RV roof and apply with a brush, roller, or sprayer. No primer is required, saving time and effort. One gallon covers approximately 50 square feet per coat, and two to three coats provide maximum protection, making it perfect for both quick touch-ups and full-roof restorations.
  • Upgraded, User-Friendly Packaging: Designed with convenience in mind, the wide-mouth container fits most brush sizes for easier application. The upgraded aluminum inner liner enhances product stability, prevents leaks, and keeps the coating fresh for future use.
  • Safe, Low-Odor Formula: Crafted with a non-toxic, low-odor composition, this silicone roof coating is safe to use both indoors and outdoors. It’s eco-friendly, pet-safe, and ideal for any environment where ventilation might be limited.

Recommended Application Conditions

Choosing the right time to coat your RV roof helps reduce the risk of poor application and curing problems.

  • Ambient Temperature:Recommended application range: 50°F–104°F (10°C–40°C). Do not apply when the ambient temperature is below 50°F. If temperatures are close to the lower limit, choose a period when temperatures are rising rather than falling toward nighttime lows.
  • Roof Surface Temperature: Keep the roof surface within the recommended range of 50°F–104°F (10°C–40°C). Avoid applying in direct midday sunlight when the roof surface becomes significantly hotter than the surrounding air. EPDM and TPO roofs can reach temperatures approximately 10–20°F above ambient conditions. Early morning or late afternoon is generally preferable, provided the roof is completely dry and the temperature is within range.
  • Humidity: No strict air-humidity target is specified in these application recommendations; normal outdoor conditions are generally suitable. Prioritize a clean, completely dry roof surface. Do not confuse acceptable air humidity with permission to apply over a damp surface.
  • Dew Point and Condensation: Make sure the roof is completely dry and free of morning dew, frost, and condensation before applying the coating. If overnight temperatures are forecast to come within approximately 5°F of the dew point, consider postponing the job to reduce the risk of condensation forming on the fresh coating.
  • Rain and Curing Conditions: Plan for a dry weather window of at least 24–48 hours after the final coat. Keep the coated surface dry throughout the curing period. Check the forecast before starting, not just before applying the final coat.
  • Wind and Direct Sunlight: Avoid windy conditions that may blow dust and debris onto the wet coating. Avoid peak midday sun, which can make the roof surface too hot for the recommended application range.

Before You Start: Important Reminders

The two most important preparation steps are a clean, completely dry roof and a suitable dry-weather window after the final coat.

Do not rush the application over a damp or contaminated surface, and do not start unless the temperature, roof condition, and weather forecast meet the recommended conditions. Careful preparation and sufficient curing time help you get the best results from your RV roof maintenance project.

Waterproofing for the roof.

Great product. I had a friend help me apply this roof waterproofing layer to the rooftop. A few days later, I went up and noticed the temperature had dropped by about 20 degrees. My friend was very satisfied and said he'd order and use this product from now on. He also mentioned that the waterproofing layer is thick and seeps into gaps well.

High-quality roof coating.

This coating is fantastic! Exactly as described. Just thoroughly clean the roof and tape the seams. Even better, it's completely waterproof. Every RV owner should try it!

Roof coating.

Works great on the trailer I'm renovating. Followed the instructions exactly. This one gallon of sealant was barely enough for my 12x6 ft trailer because it goes on very, very thick. I wanted a second coat but didn't want to buy another gallon. One coat was enough for me. This stuff is very durable once cured.

Premium RV Roof Sealant

High-quality RV roof sealant only requires two coats of rubberized paint. I bought three cans, and I found that three gallons were enough to cover my 35ft 5 wheel trailer,two coats were sufficient. Be sure to first clean and scrub the roof with a pressure washer and allow it to dry completely before applying the self-leveling sealant to all worn seams. After the seams have cured, apply a thick coat of primer to the entire roof using a medium-pile roller, and brush the seams. It provides excellent protection and a good seal for my five-wheel trailer.

The texture is very thick with great coverage.

I used it on my RV, and it stopped the leaks immediately. The texture is very thick with great coverage. Just pour it directly onto the surface and roll it evenly with a roller. No primer needed amazing results, and very white. It's very flexible! Highly recommend!

Sealing the top of the trailer.

I ended up choosing this product. Thankfully, it works very well! It sealed the roof of a 30-year-old enclosed trailer. Everything except the roof was still in good shape. Plus, the white coating helps reduce the temperature inside the trailer on sunny days. A great product.

Logan Cox
Fills cracks and gaps really well.

I used it on the roof seams of my 2008 fifth-wheel trailer. It sticks like glue no more worries about the old cracked roof sealant! Just brush it on, and it bonds firmly to the roof. It doesn't run easily and fills cracks and gaps very well.

I bought this waterproof sealant to fix roof leaks. It's easy to apply, adheres well to various surfaces like metal, concrete, and walls, and provides excellent waterproofing. I also used it around the eaves gutters and in the bathroom no leaks so far.

Works amazingly well so far!

Been using it for a while works amazingly well so far! The surface is super smooth, and things no longer stick to the roof like before. A bit pricey, but absolutely worth it!

The sealant meets my expectations.

First, clean and scrub the roof. I used a scrubber with a squeegee to clean and rinse the roof. For a 23ft x 8ft area, one gallon was enough for two coats. This paint dries slowly, so make sure there's no rain in the forecast. The roof is now completely dry.

Lillian Evans
Easy to apply with a roller.

So far, so good. I primed the metal roof of my enclosed trailer first, then applied two coats of the rubber paint. The second coat dried nicely. Hope it doesn't peel off on the first highway drive.

Penelope Campbell
This product is really fantastic!

This product is really fantastic! I love it! Easy to apply with a brush or roller, but you have to work fast because it dries quickly, and stir often to prevent skinning. Now I don't have to worry about water getting into my RV anymore.

I haven’t opened it yet. It feels like a solid block. Is it sealed in plastic or something? If so just use a drill mixer?

Kohree

Please open the plastic packaging to inspect the product. If it has already solidified, stirring it with an electric drill will not be effective. Our products feature excellent sealing properties, so solidification is a rare occurrence.

FAQs About Waterproof RV Roof Coating 1 Gallon for Leak Repair

Follow these steps before and during application to help the coating adhere properly.

1. Clean the Roof Thoroughly

Remove dirt, dust, chalking, loose material, and old flaking sealant from the roof. A pressure washer may be used only when appropriate for your specific roof material and permitted by the roof manufacturer's instructions. Avoid excessive pressure that could damage the roof membrane.

Allow the entire surface to dry completely before applying the coating.

2. Repair Worn Seams and Cracks First

Inspect roof seams and existing sealant. Repair worn seams and cracks with a compatible lap sealant or approved seam-repair material before coating. Allow the repair material to cure fully according to its instructions before covering it with the silicone coating.

3. Apply Without Primer on Compatible Roofs

No primer is needed on the compatible surfaces listed for this product: EPDM, TPO, metal, wood, fiberglass, and aluminum. Always confirm that the existing roof finish and any previous coatings are suitable for application.

4. Apply 2–3 Coats

Use a brush or roller to spread the coating evenly and at a sufficient thickness. Allow each coat to dry to the touch before applying the next.

One gallon covers approximately 50 sq. ft. per coat. Actual coverage may vary with the roof's condition and the thickness applied, so estimate material requirements before starting.

5. Stir Thoroughly and Periodically

The coating is thick, so mix it thoroughly before use and stir periodically to maintain a consistent mixture.

If the product arrives solidified, do not attempt to break it down using a drill mixer. Contact Kohree customer support for assistance.
