Just about everyone who owns any type of RV has been told that they must periodically reseal all the areas on or near their roof to protect against potential leaks. There is another source that is just as likely to cause problem leaks as those seams and vents though and that is the air conditioners if they are roof-mounted. Those A/C units sit on top of the RV but between the unit and the roof is a 14" X 14" gasket or seal. That seal is very thick, up to 4 inches, and the unit actually sits on top of that seal.

Over time the seal compresses under the A/C's weight and the unit becomes loose in its hole in the roof and thus a potential leak. It is usually very easy to access the bolts that snug the unit on the roof. This is done by opening or removing the interior return grille on each unit and exposing the 3 or 4 thru-bolts and nuts that then can be snugged down with a socket, ratchet and extension. Tools that almost everyone owns.

A leak created by a loose A/C unit can many times traverse the interior of the roof and drip out in areas far from the leak complicating efforts to determine the source. Checking the tightness of your units should be on your list of maintenance items to be checked yearly. It could save you lots of dollars.

Air conditioning leaking
by: Debbie

We have a window unit in ours. It came that way. Last year we noticed it was letting water out. We check it and it has gone inside the wall. How do we fix it and get it to run outside
