RV Water Leaks
NO ADSENSE ACCOUNT SELECTED FOR If there is a way to get in your RV,
water will find it. Water leaks on an RV can cause extensive
damage and can be extremely costly to repair. When I worked at
an RV dealership I saw the damaging effects that water can
cause to an RV time and time again. I learned the lesson the
hard way. I appraised a unit that was being traded in and
didn’t identify the extensive water damage, which resulted in a
thousand dollars worth of repairs. Hindsight is 20/20 and I
quickly learned how to inspect for, and identify potential
water damage on RVs. My recommendation is that you inspect for
potential water leaks twice a year at a minimum, once in the
fall and again in the spring.
Every seam on your RV and anywhere the manufacturer cut a
hole in your RV has the potential to allow water in. To protect
your investment and your wallet take the time to REALLY inspect
all of these seams and sealants. Water damage on an RV is
similar to progressive damage to a tire. The outside of the
tire looks fine, but the internal damage over a long period of
time causes the tire to fail without any warning. The outside
of your RV looks fine but the internal damage caused by water
over a long period of time can result in the entire roof, floor
or wall rotting away without you knowing it. Here are a few
things to look for during your inspections.
Always keep safety on your mind when you are working on the
roof of your RV You can be seriously injured from a fall! A
reader of mine suggested that you use 2 pieces of 1/2" plywood,
2 foot by 4 foot, to move around on and spread your weight out
over the roof rafters.
* To stop a leak before it starts, thoroughly inspect all
roof and body seams. Consult with your RV dealer for sealants
compatible with different types of roofing materials.
* Look for any discoloration and feel for any soft spots on
the ceiling around roof vents, air conditioners, TV antennas,
plumbing vents, and any other openings that were cut in the
* Look for any discoloration or wrinkles in the wallpaper,
and feel for any soft spots on the walls around all windows,
doors, vents, slide outs, or any other openings that were cut
in the side walls.
* Identify the location of items like the water heater,
furnace, outside shower, potable water fill and city water
inlet on the outside of the RV and then access those areas from
the inside of the RV and look for any indications of water
damage around these openings.
* Open all overhead cabinets and look in the top corner
where the walls meet the ceiling for any discoloration or feel
for any soft spots. This would indicate a leak at the seam
where the sidewall and the roof attach.
* Check in all outside storage compartments for any
indications of water leaks or water damage.
* Check for any soft spots on the roof itself especially
around the roof seams at the front and rear of the RV.
Thoroughly inspect all sealants on the roof around every
* Some Class C motor homes are notorious for leaks in the
cab over bed area. Look for any signs of discoloration and feel
for soft spots. Reach under the mattress and feel for
* Look and feel on the outside of the RV for any signs of
delaminating. Delaminating is caused by water getting between
the exterior fiberglass and the sidewall. When this happens the
exterior fiberglass separates from the sidewall of the RV. You
can stand at the front or rear of the RV and look down the side
for any noticeable ripples or what looks like a bubble. You can
also press on the sidewalls. If you feel the exterior
fiberglass move it is delaminating. Often times delaminating
starts around where an opening that was made in the
Don’t just inspect your RV for water damage; REALLY inspect
your RV for water damage. If you do this on a regular basis you
can locate and repair the source of any water damage before it
has a chance to do a great deal of damage. I think I’ll start
checking our motor home more than twice a year.
