LESLIE: Randy in Wisconsin has got a roof-mold question. What can we do for you today?
RANDY: Well, I was just wondering, I heard on a previous show that if you put a copper strip up at the top of your asphalt shingles, it will help eliminate moss, mold and mildew.
TOM: That’s correct.
RANDY: I was wondering if a bare copper wire would do the same thing.
TOM: Now, probably not enough copper there. What you want is a piece of copper flashing; that’s the easiest thing to find. You can probably find it at a roofing supply house.
But here’s the thing: there are other things you can do to avoid the buildup of the algae on your roof. First of all, if your roof is very shaded, you can cut back some trees, let a little more natural sunlight get in, yeah, just to kind of thin out those trees so the sun gets through. That will help.
Secondly, you can put a product on called Wet & Forget, which is really easy to do. You mix the solution up and you spray it on the roof and you let it sit there. And it activates with the sunshine and then it will kill the moss and stuff that’s stuck up there.
Then the last thing is you can add that copper strip to the top of the roof. And the reason you do that is because when it rains, the copper releases some of its minerals and that actually acts as a mildicide.
RANDY: OK. Alrighty. Thank you.
TOM: You’re welcome. Thanks so much for calling us at 888-MONEY-PIT.
I live in a Log home. Will any of the cleaning solution damage the wood?
Will the runoff from the copper strips cause any damage to the wood ?
