I want to cut some plugs to put under some flashings on a metal roof where
the peaks and valleys are open. Then caulk the dickens out of them. Can I
use some of that refrigerant pipe wrap? I've seen it on stuff that has been
out in the weather for a long time, and it seems to be in decent shape.
This would be under the flashing, and protected from UV, and, if sealed,
Other alternate suggestions?
