Metal roofing type and source

[Rob Tucker]

I can't explain the why of it but I have had aluminum problems at an elevation of about 800'. The aluminum screen frames on a house I own all needed replacement. They were dissolving in places. I've seen this on some aluminum roofing on edges and around nail holes too.

It may be a reaction to acid rain which happens rather rarely and ocassionally in the Pahoa area.

Ya gotta remember that ultimately everything made by man can and will be defeated by nature.
