How Do You Waterproof a Camper Roof?
Water damage can damage the interior of your camper. Your electrical system is in ruins, and upholstered furniture must be thrown away.
- Then there is the cost of your vacation plans. You don’t want to cancel your trip because of a small leak. It is frustrating when something so easy and straightforward to fix keeps you home.
- A simple 3-step process and your camper roof will be waterproof. First, prepare the surface of your RV, then add a liquid catalyst into the roof sealer’s can and brush it onto your roof.
- As long as it is above 12 degrees Centigrade wherever you apply it, the rubber you used to cover the leaking roof as a liquid will solidify into a hardened membrane.
How Often Should You Seal a Camper Roof?
Of course, how often you should seal different camper roofs will vary, but we recommend resealing your camper roof yearly.
- It is recommended to replace the entire roof every 10 years. Otherwise, there will be leaks. Leaks will damage your interior wallpaper, destroy your walls (resulting in them having to be replaced too), and mold.
- If you are purchasing a used motorhome, there’s a good chance the previous owner didn’t work on repairing, resealing, or replacing the roof. They probably didn’t know they needed it.
- If you have a new motorhome, it is recommended to have it checked every year.
Does RV Insurance Cover Roof Leaks?
If you damage your RV roof in a collision, your insurance company will pay to replace the new roof.
- The collision maybe with a sign, building, tree, or other low obstacles. This kind of collision usually tears the roof of the spoke. The spoke breaks will cause the insurance company to replace the roof.
- A hole drilled in the membrane on the large flat surfaces is given a plaster. Such damage would come from a branch falling on the roof.
- For damages caused by collisions or storms, the insurance covers the substrate, roof, and any damaged accessories on the roof.
- If you discover that a branch pierced your roof on your last camping trip, you can still file a claim.
How do You Coat a Camper Roof?
The instructions for use may vary depending on the manufacturer. However, it is not at all difficult to get it on the roof of your caravan in many cases.
- You have to measure the width and length of the roof to determine how much sealing you will need.
- Then you need to get the entire roof surface area. Multiply the width and length and divide what you get by 42.
- This calculation approximates the number of gallons you should apply to your roof.
- When applying it, ensure you have adequate ventilation in the area where you apply it.
- Prepare the roof’s surface by scrubbing or washing it. Remove the loose roof coatings and caulking.
- Using a brush to apply the sealants helps cover pits, bumps, and seams. Allow the coating to dry.
- Apply a topcoat if necessary.
Can You Put Kool Seal on a Rubber RV Roof?
You can use Kool Seal, but it should be the RV version. The regular one is NOT designed for use with EPDM (ethylene propylene diene monomer) rubber.
- To use Kool Seal, clean surface dirt using a pressure washer.
- On a sunny, warm, cloudless day (65 degrees Fahrenheit and above), apply STA-KOOL, Gardner, or Black Jack Elastomeric Roof Coating to a dry surface on the roof.
- Cut along the edges, then go from one end of the roof to the other, maintaining a continuous wet edge.
- Follow all directions on the label.
Can you Walk on Top of a Camper?
Yes, you can walk on top of a camper. To walk on the roof, you would need to climb a ladder to find out if you can walk on your camper. You can usually walk on rubber roofs, but many manufacturers use thinner plywood to reduce weight and cost. It’s not safe to walk on this type of camper.
Does Flex Seal Work on Camper Roofs?
Yes, you can use Flex Seal for RV roof or your motorhome roof! Not only can it be used to coat the roof of your RV, but it is also ideal for any other application where you want to apply a flexible, waterproof rubber coating. The Flex-Seal is designed to be extra mild. It can be quickly brushed on, poured, rolled, and leveled.
How Long Does RV Roof Sealant Take To Dry?
When the place’s weather is between 50 and 70°F, RV roof sealants typically take 5 minutes to dry and are waterproof after 4 hours. The sealant is up to 80% cured after 48 hours. It can take about 30 days to cure 100%.
How do You Clean an RV Roof Before Sealing?
Use warm water to clean the roof’s surface, then allow it to dry. For best results, the surface should be free of grease or oil. You can use acetone or methyl ethyl ketone (MEK) to remove grease stains. Wear thick rubber gloves for this task.
What to Look for?
RV enthusiasts have many opinions on what we might call the best camper roof sealer. However, if you don’t want to waste money on substandard products, consider these aspects when shopping.
The roof of RVs is made of various materials. When evaluating available sealants, it is strongly recommended to consider these properties. The last thing you should do is empty your wallet on a sealer that is incompatible with the roof of your motorhome. You can usually determine the suitability of a sealant by looking at its usage description.
B) Ease of Use
As an RV owner, you would need to deal with numerous tasks, so you don’t want roof sealers with heavy and prolonged applications. So when looking for the best camper roof sealer, it is essential to choose a product that is easy to use. Avoid purchasing until you are sure you have the tools and skills to handle the selected product’s application. Undoubtedly, hiring a professional to apply your roof sealer is always an option, but it will cost you money.
C) Curing Time
Often, the curing time is influenced by a variety of factors, ranging from temperature to humidity, and varies widely from sealer to sealer. To determine your RV roof sealer’s correct curing time, you need to think about your travel plan. If you’re planning to leave soon, prioritize sealants with quick curing times. Conversely, if you don’t already plan on hitting the road, you can opt for standard sealers.
Even on small RVs, large amounts of sealer can be required to adequately cover the roof. This means that capacity is a vital consideration. Repeatedly opening new sealant containers is cumbersome and leads to several interruptions. So it is better to be thorough. Use your roof measurement as a reference, then calculate the amount of sealant required for complete protection. It should be noted that there are currently several products on the market in containers of different capacities.
Camper roof sealers come at different prices, so you have plenty of choices regardless of your budget. However, since the price is subtly tied to the quality, you need to be careful. In general, you don’t have to spend a lot of money on roof sealers if you don’t fancy, sophisticated requirements. It’s also not advisable to buy inexpensive products to save a few dollars, as they rarely stay together for long.
