Before you choose an RV roof sealant, you need to consider the important points because there are numerous brands and products out there that sell and promise the same things. You need to know which one is telling the truth and will not lead to disappointment. This guide will show you exactly what you need to look for when buying an RV sealant and the reviews are real so you will not be misled.

Things to Look for When Selecting RV Roof Sealant

It is not just the summer rain that causes water damage because if you are living in an RV and moving around all the time, you would have to deal with the typical freezing or thawing. Unlike majority of other materials when there is an expansion of water freeze. This expansion can make seams large and there will be cracks on the roof, which creates a pathway for water to get inside the RV.


Roofs are not all the same

The RV roofs are made with several materials and each one must be treated differently. One thing to remember is that if the one your bought is designed to be utilized on the sticks you have, it is most likely that you should not try to use it on your RV.

You might have an impression that local home centers which offer membranes made for homes also sell supplies that are made only for the RV roof rubber.

Majority of RV manufacturers utilize only one kind of rubber roofing material and they are EPDM and TPO.


These are typically made without any requirement for maintenance for about 10 years after they are placed on the roof. On the contrary, there is a notion that you do not have to do too much with EPDM rubber roof instead of maybe regularly remove it with soap and water.


Due to the EPDM’s unique structure, there is no need to apply any kind of UV protectant to it or you re-coat the surface regularly.


This one is structured using a different material compared too EPDM roofs. TPO applies a shiny look on it and has more rigidity compared to EPDM. It is not as rubberized and uses less plastic. This one will not oxidize unlike EPDM and will have a surface that is chalk-like.

Washing it occasionally using mild soap and mop is the only care it needs.

Repairing the roof

The very first thing that needs to be done is to clean the roof properly so you can remove any particles. After that, make the roof dry and make sure that no debris will be left or old material. Be careful while you are doing this because you could cause a tear or elongate it, and even punch a hole. Ask the dealer which sealant is the best one for your roof.


Inspect the roof

The roofing membrane is going to last for 20 years, but it is not always a guarantee that the sealants and seams are going to. Any seam found on the roof, and another opening cut in the roof can leak. When the RV is moving and flexing while it moves down the road, it is typical for seams and sealants to move. This, together with age will cause the sealants to detach and lets a path for water to enter through the seams and sealants. A thorough inspection of roof seams and sealants are important so make sure you do it regularly. In majority of cases, the warranty can become void if you do not follow the correct inspection intervals.

Using the proper material for repair

If in case you see that there is a problem after you have done the inspection, complete all of the repairs needed. This means using the correct sealants and materials for rubber on the roof. This means including the proper sealants and materials used for rubber roofs. Do not use the wrong type of sealant because it will peel off right away after you applied it and your money will only go to waste. Majority of people use silicone products for repair and are disappointed because it peels off right away. This will only lead to more cost and there will be water repair damages that you will pay for later on.
