Applying a roof coating to your RV: How to do it and why you should

Join me in the RV shop as I explain more about applying a roof coating to your RV. Doing so can offer several benefits, helping to protect and extend the life of your RV roof.

Here are some advantages of a roof coating on your RV


One of the primary benefits of an RV roof coating is its ability to create a waterproof barrier. This helps prevent water from seeping into the roof and causing damage, including leaks, rot, and mold growth.

Leak prevention

A quality roof coating can help seal existing small leaks and prevent new ones from forming. This is especially important for RVs, as water leaks can lead to serious structural damage and compromise the integrity of the vehicle.

UV protection

Many RV roof coatings contain UV-resistant properties, protecting the roof from the damaging effects of the sun. UV rays can cause the roof material to deteriorate over time, leading to cracks and leaks.

Heat reflection

Reflective roof coatings can help reduce the heat absorbed by the RV, contributing to a cooler interior. This can be particularly beneficial in hot climates, improving energy efficiency and comfort inside the RV.

Extended roof lifespan

By providing a protective layer, a roof coating can extend the lifespan of your RV’s roof material. It helps prevent premature aging and deterioration caused by exposure to the elements.

Reduced maintenance costs

Regular application of roof coatings can reduce the need for extensive roof repairs and maintenance. This can save you money in the long run by preventing costly issues associated with water damage.

Seam reinforcement

Roof coatings can reinforce seams and seals, which are common areas where leaks may occur. This added layer of protection helps maintain the integrity of the roof structure.


Some roof coatings are designed to be flexible, allowing them to expand and contract with the RV’s movement. This flexibility is crucial in preventing cracks and ensuring that the coating remains effective over time.

Ease of application

Many RV roof coatings are designed for easy application. They can be rolled, brushed, or sprayed onto the roof surface, making it a relatively straightforward DIY project for RV owners.

Energy efficiency

Reflective roof coatings not only protect the roof but also contribute to the overall energy efficiency of the RV by reducing heat absorption. This can result in lower cooling costs during hot weather.

Before applying a roof coating, it’s essential to thoroughly clean and inspect the roof, addressing any existing issues. Additionally, choose a coating product that is compatible with the specific roofing material of your RV, and follow the manufacturer’s instructions for application and maintenance. Regular inspections and reapplications, as recommended by the product, will help ensure the continued effectiveness of the roof coating. Check with your local RV repair shops for details and products that they use.
