O.K., so here's you'se guys chance to kick my butt. One of my bestest friends has an auto parts business in an approximately 9000 sq. ft. building, and it has a flat tar and gravel (very little) roof. The building was built in 1958, as far as we can find out has never been totally re-roofed. The PO had repairs done to it which are clearly visible, but are not near to where the leak is. The roof did not leak for the first eight months he was in it, now it only takes a little sprinkle shower to start a leak. You can imagine how bad it was leaking today with about 2 1/2 hrs. of steady rain. It leaks in only one spot, same spot each time, and quite a lot. There is only one local roofing company that will mess with this type roof and it will be three weeks before they can even look at it. Any ideas as to how to find where the water is getting in at? I've been up there in dry, hot weather and can't find anything out of the ordinary to me. I do know these roofs will have a way for water to intrude here and run under the tar/gravel and leak over there. I helped my Uncle mop tar years ago and am about ready to fire up a fish cooker to melt tar and go to mopping everything (joking there). Any suggestions? Thanks, David
