[QUOTE=Sunrise Point;91556]Zinc strips up near the peak (under the cap shingles with a few inches exposed) acts as a great preventative.

This Old House has a little info @ http://www.thisoldhouse.com/toh/askt...401167,00.html

Thank you Sunrise.

I think the zinc will help with prevention (thx - upthesaukee), but I am worried about what they (This Old House) says about removal of the existing moss. They say to scrap (ouch), that sounds damaging to the roof shingles. What is the best way to remove the "built up" moss, without destroying existing shingles.

Then, what I am getting from your comments are install the zinc to keep both the "black stains" and the eventual moss buildup from occuring. Am I getting this right.

Sorry to be so dense
