We went on a 10 day vacation.
Upon returning found a 4 X 8 foot part of the ceiling in the laundry
room had collapsed due to the sheet rock getting water soaked.
The section is below the toilet in a bathroom. When we went to the
bathroom nothing was happening. No broken pipe, nothing running. Small
amount of water at end of room near the toilet. Toilet inlet pipe is not
leaking, toilet works fine. Bathroom ceiling is fine It did rain very
hard for a few days here. Home is raised ranch and entire back of house
is above ground. Did leave water on while we were gone (probably a
mistake). The puzzle is where did the water come from and why do we not
see a continuing problem? The section where the ceiling gave way is
where a lot of pipes for the bathroom run but the water on the floor
above implies the water came from the bathroom and not a pipe (also
there is no drip) Could the water have run down the outside of the vent
pipe for the plumbing? If it did how come we have water in the
TIA for any ideas.
Had a similar problem several years ago, however, we were at home and
noticed water trickling out of a removable panel under the bathtub. After
eliminating a plumbing source, we found a crack in a shingle hidden between
the tabs. Water had leaked into the tab during a heavy rainstorm. It ran
down the plywood to a seam, then landed near a horizontal vent pipe that
dropped down beside the bathtub, from there it found the removable panel
below the tub and trickled out onto the carpet where we had stepped into the
This is a common problem with early fibreglass shingles so I learned. I had
to check the roof every spring and fall looking for cracks between the tabs.
When I had it re-roofed this spring, I must have had at least a couple of
hundred spots sealed up with silicone caulking from finding new cracks every
Don't feel bad about not turning off water. Turning off water can cause
leaks too by reducing pressure on connections as my neighbor found out and
his attic water heater drained into his washer dryer room when he was on
This happened to a friend of mine - after I left her house one weekend. I was in town
to see a football game and they
let me stay there even though they left the day before. Apparently, they had problems
with the toilet in my bathroom
overflowing. They told me this later.
I guess I used the bathroom right before I left, otherwise I would've noticed the
water in the bathroom floor.
When they returned from vacation a couple days later, their master bath, which was
below my bathroom, had water damage
all over the ceiling and walls.
