How to Buy the Best RV Roof Coatings

How To Buy The Best RV Roof Coatings
How To Buy The Best RV Roof Coatings

While it is true there are many kinds of RV coatings from different companies in the market, you should not just settle for any. To make sure that you make an informed choice you need to watch out for the following things when shopping:

1. Types of RV Roof Coating

Before you start shopping for a good RV roof coating, you will first need to decide the type you want to buy. And here you will often need to choose from 5 main options which are rubber, liquid, aluminum, fiber glass and roof caulk.

Rubber Coating

RV owners often prefer to use rubber RV roof coatings over most other types and there are generally two types of rubber coating. One is made from thermal poly olefin and the other is made from ethylene propylene diene monomer. Both of them are protective enough but they require different levels of maintenance.

Liquid Coating

Liquid coatings prevent corrosion and are water repellent. This coating is very easy to apply and will give you an easier time than most others. It is more of like painting the roof and since it also provides protection against UV rays, you can expect good durability.

Aluminium Coating

The aluminum coatings are not widely used because they add to the overall weight of the RV. Also, because not all the roofs are made of aluminium, it might also not be appropriate for some RVs with non-aluminum roofs.

And to apply this coating, you should have proper knowledge of the application procedure as you can easily ruin the roof. But, on the bright side, with the best RV aluminum roof sealants you will get some of the toughest roof coatings.

Fiberglass Coating

Fibreglass coating is used a little more often than aluminum coating. The maintenance is low as compared to aluminium coating. But the application process is not easy and you might have to call in a skilled professional to get it done. Also, it is costly and also adds to the overall weight of RV.

Roof Caulk

The roof caulk majorly prevents corrosion of metallic parts. The process is called caulking and it prevents water from getting in the recreational vehicle. Because different caulks serve different purposes, you need to check your RV type to get the best product.

2. Durability

Durability, no doubt is the primary reason you invest in RV roof coating. As you may know, reputed brands offer a good amount of durability and make the product serve you for longer.

While choosing any roof coating, don't forget to check the brand you are buying from as it is a good indication of the durability.

Also, the materials and the ratio of the ingredients used to make the coating will determine how long it will last and hence the frequency of reapplying it.

3. Ease of Application

You do not want to invest in a product that is pretty hard to apply as it can take up a lot of your time. The roof coating must follow easy application process, so you can do it yourself instead of calling a professional for help.

Also, check if the cleaner or activator is already included if a roof coating requires it as this will ensure an easier time for you. And the cleanup must also be easy when the coating dries.

4. Water R epellent

The roof coating has to be waterproof in order to prevent rain water from entering in and also to ensure it can last long enough.

As the weather changes your RV roof will be exposed to different elements and a water-repellent roof coating will give it much-needed protection.

5. UV resistance

UV rays produced by the sun are quite harmful for both the RV and its inhabitants. Hence, any RV roof coating you choose should create a protective barrier against sun rays.

Plus, UV rays can ruin the roof top so the roof coating should have the potential to avoid sunlight from getting through.

6. Price

Price, is definitely a deciding factor for all. When you are done with considering all the factors above, the ultimate buying decision will come down to how much money you are willing to spend.

Usually, the products with high price tags are from the reputed brands and they are also better quality and more protective.

But that is not always the case, so it would be better to check the customer reviews first before deciding whether to splash a lot of cash on any RV roof coating.

Conclusion

A good RV roof coating will give your motorhome much needed protection from the elements and also keep it looking neat and clean for a long time.

To choose the best RV roof coating from the many options out there you will need first to decide the type to buy and consider other factors like ease of application and price.

And regardless of the RV type you have and the level of protection you want you can be certain that there is at least one product from our review of top 10 products above that will work well for you.
