Roof Leak Questions

Rich Phillips 1 - 22 Sep 2005 14:25 GMT
I recently discovered signs of a roof leak in my Jayco fiver (small pool of
tan-colored water on the counter under a window, light brown water leaking
from the upper corner of the roof at the rear and from a tail light
housing -- all after a rain). There are no soft spots on the roof, no
delamination of the fiberglass sidewalls, or bubbling of the ceiling
material. In short, it looks like nothing critical has happened yet.

Starting this afternoon, I will do all the usual things to find and seal the
leak on top. But am concerned about the long-term effects on the trailer of
having been exposed to water for an unknown period of time.

How well does wet wood dry out once the source of the leak is repaired?

Is there any way of knowing if the amount of water that has gotten in
will -- in time -- start rotting out the plywood and wood joists?

The color of the leaked water does worry me -- does that mean that there is
rotting already going on in the plywood?

Any help would be appreciated.

Plenty has happened already. You have wet insulation that will take
forever to dry and if it's wood framed you will surely have decaying
wood. That's the reason your manual says inspect for open seams and
repair. Most say yearly. I inspect every 6 months.

You may be able to reduce damage by putting a dehumidifier in the rig
with setting set as low as it will go. Drop fixtures in the area of
the visible area so there is air circulation to the wet area. The
actual outside leak may be several feet from where you see it inside.

Thanks for the comments. I've been checking the seams and joints pretty
religiously -- no problems there. It seems the water was coming through the
TV antenna. The rubber boot that seals the coax cable entry point had come
loose, and the tube that it usually covers acted like a little funnel,
channelling rain to the inside. My guess is that it was brushed loose by a
tree branch on our last trip.

When I talked to my dealer's repair staff about it, they said this was not
unheard of, and so I guess that's something to add to the inspection
checklist.

It rained last night quite heavily and there are no signs of new water
getting in now that I've re-seated the boot. I'll probably also add some
kind of additional band or seal to make sure it stays on in the future.

I'm headed Monday to stay in the Utah desert for 5 weeks, so hopefully the
low rainfall, sunshine, and low humidity out there will cook out the
remaining water.

I used a stainless steel "gear" clamp to clamp the boot in place on my
rig. That was a few years ago and it's still in place. It's the kind
with the spiral gear like those used for after market on 1/2 & 3/4
hose fittings.

Any thoughts of removing the TV antenna?
I have on on my rig that I don't use and never plan to use.
It is amplified so ther is drain on the batt.

Are you planning on keeping the rig for ever? If not, the next owner
may just want the antenna.

The amplifier has a switch. Turn it off. Then no battery drain.

Quite frankly, I don't care what the next owner wants.
I own it now and probably for the next 10yrs.
I need the roof space for solar. Antiquated TV on a antennae which draws
power from a battery is a waste of energy.
How many people actually use the powered antennae?

I think most people would use satellite, dish, or sustain there own movie
collection.

BTW: I drilled holes in the sliding bed compartment over the cab so that I
could mount a flat screen and use a GPS, while driving.
I seriously doubt the "next owner would want this".
I don't care, I paid for it and it's mine for the time.
Maybe you have the ability to waste resources. I do not.
I will keep this MH for a minimum of 5 probably 10 yrs.
If the engine is good and it is structurally sound keep it.
If I drive it 5000 miles each year for the next 10yrs, I'll have 65,000  or
70,000 on it.

To answer your question, yes. I will keep it forever based upon your
standards.

More than you think.  I use one.

The next time you're at a campground, count the number of rigs with their
antenna cranked-up.  I think you'll be surprised.

They're different things?   :)

> or sustain there

Where?

> own movie collection.

No satellite while camping for me, at least so far.  I already haul and deploy
ENOUGH stuph when camping.

When we moved OVER (not up) to a travel trailer from a popup camper, I bought
a little TV because the new trailer HAD the amplified (powered) antenna.  We
use the TV rarely but it's nice when we want it.
