The Threat Of Algae To Your Roof

When it comes to your roof, you may be aware of common issues, like leaks, and the steps needed to prevent them, such as quality waterproofing and proper ventilation. But are you also aware of the need to prevent algae buildup? It would be a mistake to ignore the very real threat of algae, and other contaminants like mold and mildew, and the major damage they can do to your roof.

Are you unsure of whether algae is present on your roof? The surest sign of algae can sometimes be mistaken as dirt—long black streaks on your roof’s shingles. Those streaks are caused by a type of algae known as Gloeocapsa Magma, a hearty algae sometimes referred to as Black Roof Algae. This algae eats away at the limestone filler in roof shingles, taking root on your roof and spreading over time. As the algae grows and spreads, it absorbs moisture, deteriorating the shingles as it prevents them from drying. This can drastically shorten the life span of your roof. If left untreated, you may be incurring the major expense of a brand new roof much sooner than you anticipated.

Another harmful roof contaminant is mold. Mold is attracted to damp, humid environments. When algae causes your roof shingles to deteriorate, cracks appear and let in moisture. That is a prime environment for mold to grow. Once mold appears, so does a serious health risk to you and your family. Breathing in the harmful spores of mold can be very dangerous, particularly to young children or others with respiratory illnesses.
