Water is the number one enemy of an RV. A small roof leak can turn into soft floors, ruined walls, and a big repair bill. The good news: most roof leaks are easy to catch early if you know where to look.
Check your roof twice a year
A quick roof check every spring and fall is enough for most rigs. Also check after any hail or a big storm. If your RV sits under trees, check more often, since branches and sap are hard on the roof.
Always use a sturdy ladder and be careful. If you are not comfortable on the roof, a local pro can do the check for you.
What to look for
- Cracked or peeling sealant around vents, the AC unit, skylights, and antennas.
- Gaps at the edges where the roof meets the walls.
- Soft or spongy spots underfoot, which can mean water is already inside.
- Stains on the ceiling inside the rig, especially in corners and around fixtures.
- Dried-out or lifting seals on the roof membrane itself.
Keep water out
- Clean the roof first. Dirt hides cracks and keeps new sealant from sticking.
- Reseal problem spots. Use the right sealant for your roof type. The wrong product can peel off fast or even harm the membrane.
- Do not ignore small cracks. Sealant is cheap. A rotted roof is not.
- Watch the seams. Edges and corners move as you drive, so they crack first.
When to call a pro
Call for help if you find soft spots, stains inside, or sealant that is peeling in more than one place. Those are signs water may already be getting in. A pro can find the source, reseal it right, and tell you if any damage needs more work.
Catching a leak early is the cheapest RV repair there is. A few minutes on the roof twice a year can save you thousands.
