If it’s not dirt, what is it?
You might be surprised to learn that a bacteria is responsible for roof staining. According to Softwash Systems, Gloeocapsa Magma is the predominant cause of black streaks. However, other forms of microorganisms such as algae, lichen, moss and mold contribute to the problem.
These same troublemakers can also be found growing on other exterior surfaces of your home. It’s not uncommon to see stains and algae growing on surfaces such as vinyl siding, wood and more.
