Anyone ever heard of tacking a piece of bare copper wire on the ridge line
of a house to prevent asphalt shingle mold?

The theory sounds solid, since most of the mold inhibitors contain copper.

It has been discussed many times, Yes, it will work. It may take several
pieces of wire several feet apart.

I've used this stuff on two different homes here in Central Florida with
perfect results, no mildew/fungus build-up. One home has had it in place
for 10+ years and no signs of a problem.

Suggestions:
1) Remove existing mold. A pressure washer on a conservative setting
works well. You should be able to remove mold without damaging
your shingles. (Yes, I have experience with this).
You can also use bleach to remove existing mold, but I prefer the
pressure washer. Test a small area first to determine that the bleach
treatment is ok. If you've got some spare shingles in your garage or
shed, test on one of them.
2) Purchase copper strips designed for the task of preventing future mold.
The strips aren't that expensive and they work well. Copper salts of any
sort are pretty deadly for all plant life.

Good luck,
