Had heavy water come sideways in through my ridge vents... went out to
the car after the power went off and noticed what looked like a spot of
blood on the garage floor. Flicked the flashlight up to the ceiling and
saw these blood red spots. I grabbed my digital camera and am glad I did
because the next morning there were big water spots but not these weird
I did go up the next day and there is nothing up there over the garage
but the rafters and the back of the drywall.
Roof was replaced about two years ago and I have the roofing guy coming
out to see if there is more problem than just Ivan.
Garage is 35 years old so I think this has to be exhaust condensation
due to the supersaturation of the drywall.
any other ideas? you ever see anything like this?
I've seen stains like that on walls in my mother's former house. She was a
heavy smoker and one day had a leak. The residue of years of smoking
liquefied and then formed streaks like your first photo.
It could be exhaust particulates loosened from the ceiling surface by water
but it could also be mold/mildew. To be safe I'd treat it with bleach.
how would you tell if it were a mold - mildew - fungus? I suppose there
is some way to test for it???
The attic appears clean and dry - well, dry until Ivan. I have an
elaborate drain system in my basement and got water there too. First
time I've ever seen water in the basement. My patio was about 12" deep
at one point and I am the highest house in this area. Never seen so much
I had ridge vents installed with the new roof in Oct.2002.
Looking at the photos, it is not mold. Something appeared to have leached
out of the drywall and evaporated by the next day. Seems oily as it didn't
mix evenly with the water. Very odd something with such deep color would
vanish without a trace.
I did a deep search on mold and mould. The only info on RED mold I could
find is Legionella and a powdery red mold that affects hops and bread
(and a variety of molds about jello, cheese and candles). But mainly
molds/moulds of any kind develop AFTER the water damage. Not during.
Even read the whole EPA mold site.
I am now more of the opinion of "r" who wrote:
35 years of exhaust fumes...???
I tried spraying water on the walls of the garage but it just ran clear.
I loaned out my ladder so I can't get to the ceiling to try it just yet.
And yes - these are really bad water spots on the ceiling now and the
drywall is buckled and and abraded looking in a few spots showing it was
really soaked but none of the red drops show. Did seemingly vanish.
Drywall will probably have to be replaced. This was an AMAZING amount of
water that came down via Ivan.
I saw where some of "the red" dripped on the plastic shelves at the end
of the garage. I sprayed some water on these spots to see if I could
"awaken" any smell, but can't find any. The spots were hard to liquefy
and wipe up... dried a brownish red like dried blood.
If I had not gone out to the garage that night, I never would have seen
it. It was all gone by the next morning. I would have been REALLY
puzzled about the spots on the shelves though.
http://home.comcast.net/~sterhill/ceiling/garage3.html is another shot...
Water could have dissolved something like wood dust or insulation or (!)
then leaked thru seams and nail holes in sheetrock. The darker red dots look
like where the liquid dripped to the floor, then, over time, evaporated at
those drip-spots, leaving a concentrate of the liquid, making it darker thru
concentration. I doubt it is mold. If it is an organic liquid, whether mold
or not, it will lighten up with bleach. Feel it , touch it, smell it. Prob.
will give you a hint.
The color is nothing like red mold that I've seen in Florida, and mold
doesn't grow as soon as a surface gets wet. Almost like something had
accumulated on the ceiling - didja do a sanding project in the garage
that produced a lot of dust? It is truly difficult to imagine something
permeating from above and not leaving a ring on the ceiling??!? I'd
take it easy on the "smell testing", if it should be residue of some
critter living in the attic. You could touch it up, make it look like
the madonna, and sell tickets :o)
this seems logical - and keep in mind this was quite a lot of water.
Does not seem to me that mold could grow while the water is pouring through.
Almost like something had
no, but I have only lived here since 1997 - house is 35 years old - the
people I bought the house from did a lot of quality renovation here. New
kitchen, refinished hardwood floors, quarry tile in kitchen, den,
hall...He (or she) could have had some "interesting" project done in the
They were transfered before they did anything to the garage. It needs
painting and, now, new drywall on the ceiling. Had not thought about this.
It is truly difficult to imagine something
there ARE two BIG 3 - 4' dia. dark water spots - just no little red
spots. The spots are bowing and I will probably have to replace the
drywall. And there are red spots on the shelves beneath.
I did go up there the next day - difficult area to get to! and the
backside of the drywall has no obvious stains nor is there any
indication of nests, etc. No insulation there. Very clean - almost swept
looking. Definitely NOTHING right above the spots BUT since the drops
disappeared the next morning, anything above might have disappeared too.
I did NOT go up into the attic while Ivan was pounding and the power was
out...call me a wuss if you will.
You could touch it up, make it look like
I do hate a mystery that I can't solve.
From the photos, it looks more like an orange mold.
And the spores could have already been there, waiting for
water. With drywall being a very good substrate.
