Aluminum flashing won’t protect against algae on roof

Q.    I have the black algae problem on my roof that you have mentioned on several occasions. I wonder if using strips of aluminum flashing under the ridge cap would be as effective as the other metals you have mentioned. I am 83 years old and can’t do very much but I have a grandson who helps me a lot.

A.    Sorry, but it does not work. The strips need to be copper or zinc-plated. One good brand of zinc strips is Shingle Shield. Their Web site is www.shingleshield.com. The strips are installed under the first course of shingles below the ridge cap shingles.
