I've been working on our swamp cooler each day, since last weekend. Today I
felt like I finally got all of the leaks fixed, etc, and we've got the swamp
cooler running. But there is one thing which has me concerned. Jonathan
and I
went up onto the roof to check on it and found that there was a wet spot,
about
4 feet below the swamp cooler. Howwever, there is no wetness leading to it.
For
the life of me, I can NOT figure out why this wet spot should be there, all
by itself.
The only thing potentially significant is that last year we had our roof
replaced;
perhaps something was left undone???

What do you think has caused this problem?
