What are the ugly, dark spots on my roof?
Any black stains on your fiberglass shingles are probably caused by Gloeocapsa magma. More commonly known as roof algae, this cyanobacteria feeds on moisture and the limestone fillers in shingles. Once the black stains become noticeable, they will continue to worsen. This is harmful to your roof because the growth holds moisture in the shingles, which in turn causes premature aging, rotting, and granule loss.
Could these stains could be costing me money?
Besides reducing your home's curb appeal, these stains could be cost you money! If your roof has algae, studies indicate that the temperatures under your roof become higher, increasing your monthly air conditioning costs and possibly even shortening the lifespan of your air conditioning unit. Also, the same studies suggest that the lifespan of your roof is shortened by the increased granule loss, resulting in premature roof replacement.
