Water is the number one enemy of an RV. The good news: most leaks are preventable with a few habits and a yearly professional inspection.
Habits that prevent leaks
- Inspect the roof, seams and sealant every year — and after storms.
- Re-seal cracked sealant before it opens up.
- Check window and door seals for gaps.
- Keep slide-out seals clean and conditioned.
- Clear debris and leaves from the roof and slide toppers.
- Use vent covers so vents can stay cracked without letting rain in.
- Store the RV covered or under a roof when possible.
Inside the RV
- Look under sinks and around the toilet for drips
- Check the water heater and pump connections
- Watch for soft spots in floors near walls
- Notice musty smells — they’re an early warning
After rain
Walk through the RV after the first storms of the season. Look at ceilings, corners, around windows and inside cabinets.

Some leaks are invisible until the damage is done. A yearly inspection catches them early. See free fall roof inspection and how we trace hard-to-find leaks.

How often should I re-seal my RV roof?
Inspect it yearly and re-seal wherever sealant is cracked or separating.
Do RV covers help?
