Gloeocapsa Magma is characterized by those big black streaks you see on an aging roof. It is most common on Asphalt shingles and can is a spore based algae, it lives on the limestone in your shingles. When it feeds it degrades the limestone and eventually if left untreated, will take over the whole roof making it look “all black” when that is not the color of the shingle itself, that is in fact the algae growing on the shingle.
For homeowners with metal roofs, this type of roof growth is a combination of algae and fungus. When these two growths get together they can produce living organisms living on your roof. The lichens will use their perennial root structure to attach tightly and stubbornly to your metal roofing surface which makes them extra difficult to remove. If you do not remove the Lichen in a timely manner, they can damage your roof permanently and even cause surface rust which can turn into structural damage weakening your roof’s composition.
A less common roof issue, but this is the one everybody is worried about especially on the inside of the home! Mold is a very un-healthy plant that can grow on your roof. Moldy roofs can be detected in brown or black areas, or it can accumulate as a stinky smelling area that can be slippery as well. Mold loves areas rich with water such as rainy climates or an area where the irrigation system is constantly spraying every morning.
