How often should you caulk a roof on a RV?

Water damage is one of the most common causes of RV repairs, and the cost of fixing a leak can get pretty pricy pretty quickly! That’s why most experienced campers recommend you go over your RV roof coating and reinforce seams with RV roof sealant once the roof starts showing signs of ageing. Use RV roof caulking around roof vents, skylights and any other areas where something has been secured to the roof.
