Very impressive Vern! Thanks for all the photos and descriptions. "This Old House!"
============
When I had a new metal roof installed a few years ago, there was some leftover materials. This is aluminum so I kept everything. Included were a bunch of this angle trim cut-off pieces. Complete with adhesive strips!
I was looking at the metal roof I installed over my back patio using Galvalume and where it butted up against the roof I had some panel sagging and in any kind of strong rains I would get some dripping. Not cool!
About a week ago the dots connected in my brain and I found a use for those cut-off pieces! Installed these on Sunday and with our recent rains it's worked fantastic to address the drips I had. Stoked to have found a use for these little pieces I had held onto for the past few years!
I pre-drilled some small holes to help when fastening. Used those little 1/4" Florida room screws.
