Hello.
I purchased my currently home about a year ago. Recently I have noticed black stains, algae, and Moss on certain parts of the roof. These were not present when I purchased the home. I assume the prior owner had these problems cleaned up.
I have read you can apply Zinc or Copper strips to the roof to prevent the black stains and Moss from coming back once they are removed with a non-chlorine based solution.
My question is what is the best way to attach these strips to the roof. Most articles talk about nailing the stripes to the roof. I am hesitant about nailing the strip. Any other ideas?
Thanks for the help.
