Thanks everybody. I will call some local masonry people. There are a
couple
in the town where the building is located. When I called early this
summer,
they were way too busy to visit...perhaps now they have time for a
chat.
I do know this...When they put the new roof on a few years ago, they
put
no flashing at all....I guess I never noticed until you mentioned it
and I looked.
Thanks again everybody.
