How often should you recaulk your RV?

There are two answers to this question: the by-the-book answer, and the quick-and-dirty answer.

• By the book: Inspect all camper exterior seals every 90 days (or as often as your warranty requires). Reseal and recaulk as necessary. Replace all exterior seals every year.
• Quick n’ dirty: Inspect all camper exterior seals every 90-180 days. Reseal and recaulk as necessary. Replace all exterior seals every 3-7 years.

Both answers require you to inspect your RV every 3 to 6 months. But once outside of the initial 1- or 2-year warranty period, many RV owners choose to fully reseal their rigs every 3-7 years instead of annually.

• Many modern TPO and PVC RV roofing membranes do not require any periodic recoating.
• If you have an EPDM roof that requires recoating or reconditioning, most RVers will clean and reseal their EPDM roofs every 1-2 years.
• For a semi-permanent solution, consider an RV liquid rubber roof coating like RV Armor.
