We recently moved into a house built in 2002, and the living room has a bay window with a copper roof. Recently, in a heavy rainstorm, our ceiling in there was leaking (luckily, right over the Christmas tree). I had a roof inpector take a look at the copper roof, and he said that it was the worst copper roof job he had ever seen. The roof meets the house behind the siding, which is allowing water to enter the home. The original installers also used caulk instead of soldering the seams. We currently have a proposal to have the copper roof replaced and soldered correctly, as well as the siding re-installed to achieve proper drainage -- to the tune of $2100! Does that sound right to everyone, or is there some simpler, more inexpensive way to go about this?

Thank you!
