Over time, the foam gasket under your rooftop AC unit can compress, crack, or harden, breaking the waterproof seal. Signs it's time to replace: • Water leaking into the RV around the AC unit during rain • Visible gaps between the AC base and the roof • Compressed or flattened foam that no longer springs back • Increased road noise or vibration from the AC unit Regular inspection — especially before and after winter storage — helps catch gasket wear before leaks develop.
