roof zinc strips - varkpilot - 09-30-2017
Houseowners in our area appear to have good luck with zinc strips to prevent moss, etc and spraying 50/50 vinegar & water to kill existing stuff.
Solid strips or roll of zinc? Personal preference?
Regular galvanized roofing nails to fasten???
Any guidance appreciated!

It's been more than a few years, but I've used them before. I used the rolls and stretched them out 1 shingle row below the ridge. I used nails that had rubber washers under the head to hold it down. I think that was all per manufacturer's directions. The stuff i used was called Z moss as I recall. This house was in the woods, lots of large trees and shade. so the moss problem was bad, but those strips did reduce it hugely...though they didn't completely eliminate it. I noticed over the years that the strips curled on the edge and what was not-so-attractive became downright awful. Maybe it was just me, because when we sold the house nobody noticed the strips.

Our house has them on the north side, it's been on for at least 5 years-no moss. Not a lot of trees, but old roof started to get moss, and I cleaned it off, and installed the rolled zinc. It worked! I think it's personal preference strips or roll. Might get strips to lay flatter, but I don't think it's a big deal. Snap a line. Don't remember the nails-sorry.

I've used the roll and it worked as advertised. I tucked them above the ridge cap. Lifted the shingle and nailed the strip down about every 3ft. Then let the shingle back down. Just like doing a shingle replacement.
It takes a while for them to kill the stuff but it will die and mostly disappear.
