8 Best RV Roof Sealants (Choose Best for Your Camper)
You can protect the roof of your RV (recreational vehicle) if you use a quality roof sealant. Therefore, it is very important to regularly maintain the seals on your RV roof, if you want to avoid these problems in the future. If you don’t get this job done sooner or later, you will face a roof leak that will cause damage to your vehicle. Below, you can see the eight best sealants and choose the best model for your RV. So, let’s start!
What To Use to Seal Your RV Roof?
Having several different options to seal your RV roof is always a good thing. RV owners often use liquid sealant that comes with a tube. By using this method, you can easily solve minor crack problems effectively. Each brand has its own recommended use, so read the instructions carefully before doing this.
RV users also often use sealant tape as an option. This tape can create an airtight bond at the edges from the penetration of water into the vehicle’s interior. It is an excellent tool for roof maintenance, but also for repairs.
RV owners have a custom of protecting the rear and front ends of the RV with sealant tape to further secure them even before any problem arises. To make sure that your roof does not leak, we recommend that you always carry sealant tape on your trip. You never know if you will have unexpected problems such as, for example, damage to the roof in a collision of a vehicle with a branch. When it comes to smaller cracks sealant tape is a quick solution.
Types of RV Roof Sealant & Coating
To always enjoy your RV trips, the use of the right RV roof coating is also essential. Get familiar with several different options when it comes to roof coatings for campers and roof sealants. Read also what is available in this product category.
This type of coating is great for off-road use. It protects your vehicle from small branches and debris that can suddenly hit the RV roof. This coating also prevents the formation of puddles of water on the roof and provides the vehicle with excellent protection from UV rays.
It is also very durable and is among the best options when it comes to coating. But this product also has its drawbacks. It is not cheap, especially considering that a double coat is recommended for effective protection. Also, if you plan to use it, be prepared for an intense and unpleasant odor.
When you are looking for reliable protection and need to save money, the acrylic coating is a perfect choice. It provides reflectivity leak protection and is resistant to UV radiation. This coating has a short life span, does not prevent the accumulation of water, and is easy to peel and wear, which often results in leaks. To be more effective, it is recommended to apply two coats.
It is a bit more expensive coating solution, but it is definitely worthwhile given its effectiveness. For a quality coating, only one layer is enough, which positively affects the budget you have at your disposal. This product has great durability and high reflectivity and protects the roof against water accumulation. It is also characterized by long-lasting elasticity. It will not harden too quickly, nor will it get sharp edges.
Choosing a Roof Sealant for an RV
In order to choose the best possible option to seal your RV roof, you need to consider several things. Here are the things that you need to pay attention to.
Inspect Damaged Area
There are different ways to solve the problem when it comes to small or large sealant cracks. So before you decide which product to use, thoroughly inspect the entire RV roof, not just the first damage you encounter. When you climb on the roof of the vehicle, do everything possible to fix the crack that was noticed and deal with other similar problems that you encounter.
What Roof Material Does Your RV Have?
Although most RV roofs are made of rubber, it is not uncommon for them to have a fiberglass or metal roof. Clearly, each material requires a different approach when it comes to sealants. Therefore, you need to be very careful. If you use the wrong sealant you can harm it and create a big problem. In a situation where you are not sure which sealant to use it is best to consult the manufacturer. The customer service will be able to help you.
Choose the Right Seal
If the RV is used through all four seasons, the vehicle is exposed to drastic changes in temperature throughout the year. That is why it is important to use a sealant that is flexible and also resistant to spreading when it comes to roof protection. This is the best way to protect the roof of your RV from damage.
The roof of your recreational vehicle is often exposed to direct sunlight unless it spends most of the time in a closed warehouse or under a shade tree. The high temperatures that the sun’s rays create on the RV roof can significantly damage it. So when you go on the roof to put a new sealant be sure to have protection from UV radiation.
