Good news - at least temporarily. The leak has stopped. The spot is drying. It is an ice buildup that is causing the problem. The ice is melting and the seam is clear. Neither Kendall nor I am climbing out the window to slide around on an icy roof and investigate the problem further. With rain tonight,I can get Dan,the Man here on Friday to take a look. Thanks for all the input.

This is no where near as bad as the series of leaks I had in my NYC apartment. Ground floor unit. Every time an apartment over me had a problem, the water showed up in my place. The worst - I had just gotten the latest settlement from the insurance company, re-papered and painted both baths, and...within 2 days of each other both were destroyed AND my electricity shorted out.

I can handle a little mold in a closet.
