Earl -

When you say you turned them off, do you mean you closed the isolation valves to the lines going to and from your roof?

In my experience, 10 year old valve seats on cheap bronze valves typically leak by after a few years... Cut the pipe and cap the lines. Or buy a gallon of roof cement and go trowel over the area where the panels are attached at the roof. Better yet, re-flash the penetrations.
