How to Protect Your RV Roof From Sun Damage. Travel Trailer Roofs

The rubber roof of a recreational vehicle is exposed to the sun for weeks or months at a time. Eventually this exposure to ultraviolet rays will make the roof materials break down. If leaks develop, your RV could suffer major damage due to rotting wood in the ceiling. Take steps to protect your RV roof from sun damage.

    Clean your RV’s roof regularly. Dirt contains not just soil but acids from pollution that will cause the rubberized RV roof to crack. Use a mild soap and a long-handled brush with soft bristles. Scrub the cracks and caulking next to roof vents and skylights.

    Seal the cleaned roof surface with a silicone-based sealer. The higher the silicone content, the greater the UV protection. Commercial RV roof cleaning and sealing products have added UV protection ingredients. Use a paint roller to apply the sealer.

    Cover your RV when you are not on the road. RV covers are made to fit a range of makes and models. Look for one made of UV-resistant materials that has vents to keep moisture from being trapped.


    • Be careful while walking on your RV roof not to step on fragile plastic skylights.
