Your RV roof serves as the primary barrier against the weather. Rain, sun, snow, or wind—your roof takes it all. That’s why keeping it in good condition is so important. One of the key steps in maintaining your roof is using RV caulk to seal seams, joints, and vulnerable areas. If neglected, leaks can lead to costly damage and even compromise your RV’s structure.
Over time, the RV caulking around vents, skylights, and seams begins to break down. Even a small crack can let water in, causing hidden damage inside your RV. To avoid this, you should inspect your roof at least twice a year—or after major storms—for cracks, worn spots, or peeling caulk. Catching these issues early helps extend the life of your roof.
