How to Remove Black Marks on a Roof

  • Transcript

    LESLIE: Jean in Pennsylvania needs some help with a roofing question. You’ve got black marks on there. Do you think it’s moss? Tell us what it looks like.

    JEAN: I don’t know what it is. It is in the sun most of the day, so it’s not under a tree or it’s not in the shade, really. And I don’t know if it could be some kind of a mold or something that would be causing it. I tried spraying it with bleach to no avail, so I was wondering if there’s some product out there that …

    TOM: Yeah, there’s a product called Wet & Forget that will work very well for this. And just like the name implies, you simply mix this up – it’s a concentrate – you spray it on the roof and it sits on the roof. And if there’s any mold, mildew, algae that’s causing these stains, it will attack them and make them disappear.

    JEAN: Oh, well, that’s good. It probably is a mold because even though my driveway is in the sun all day, I found that there was a mold accumulating on that, also. So I guess I could use the same product for both?

    TOM: Absolutely.

    JEAN: Great. Well, thank you so much.

    TOM: You’re welcome. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
