This kit includes a 5-gallon sealer, 1-gallon EPDM primer, a smart cleaner, seam tape, and lap sealant, making it an all-in-one package for roof maintenance. One of the standout features is its flexibility, with the final membrane boasting over 1000% elongation, which helps prevent adhesion failure.

The 5-gallon pail is sufficient for RVs up to 30 feet, requiring 2-3 heavy coats for optimal coverage. However, it's important to note that full kit returns are the only accepted return method, which could be inconvenient if you don't need all components or if there's an issue with part of the kit.

The product weighs 40 pounds, which might be a bit heavy for some users to handle alone. This kit is ideal for RV owners looking for an effective, long-lasting roof sealant that is easy to apply and environmentally friendly.

The Liquid Rubber RV Roof Coating is a versatile and effective solution for sealing camper and trailer roofs. As a solar reflective sealant, it promises excellent UV resistance, ensuring that the product remains stable and effective even under prolonged sun exposure. Its high flexibility with over 1000% elongation helps prevent adhesion failure, making it a durable choice for various weather conditions.

Waterproofing is a key strength, preventing leaks and protecting the roof's integrity over time.

The environmentally friendly, water-based formula with no solvents or VOCs is safe for both indoor and outdoor use, making it a responsible choice for those conscious about environmental impact.

However, at 44 pounds, the 5-gallon container is quite heavy and may require extra effort to handle. Additionally, achieving the recommended thickness might require multiple heavy coats, possibly increasing the application time. Despite these minor drawbacks, it is a reliable and favored option for RV roof maintenance.

The Countryman Coatings 100% Silicone Roof Coating is a strong choice if you need to seal and protect your camper's roof. Being silicone-based, it offers excellent waterproofing and flexibility, which helps it handle the roof’s expansion and contraction without cracking. It sticks to various roof surfaces, including metal and rubber, and you don’t need to use a primer first, making the application easier and faster. The coating is also highly UV resistant, reflecting nearly 90% of harmful rays, which helps prevent roof damage and lowers interior temperatures—this could reduce your energy costs by keeping your camper cooler.

One thick coat covers about 55 square feet, so you might need fewer coats compared to other products, saving time and effort. It dries to a glossy white finish, which adds to reflectivity but may show dirt more easily. The full cure takes about a week, so you’ll want to avoid heavy rain or use soon after applying. It’s durable and made in the USA, with many users giving it positive reviews.

The main downside is the weight (about 49 pounds for the 4.75-gallon size), which might be cumbersome for some to handle. Also, while it adheres well to most surfaces, very damaged or structurally weak roofs may need repairs before using this coating. This product is ideal for RV and camper owners looking for a long-lasting, waterproof, and UV-blocking roof sealer that’s not too complicated to apply.
