Extensive mold growth can also expose the interior of your attic or crawlspace to mold spores carrying the problem over to the inside not to worry though because you can clean the mold off with basic household bleach and save.

Black mold on asphalt shingles is ugly. There are a number of commercial products available that will get rid of mold but if you don t mind working at heights getting mold off roof shingles is really something you can.
