Gloeocapsa Magma Algae Stains on Roof

Unfortunately you cannot prevent these algae from happening. In the end your best solution is to have your roof cleaned or replaced.

Algae, Fungi & Lichen Roof Stains Due to Climate & Limestone in Shingles

But why do some homes seem to have this problem and not others? Well black streaks became a problem about 20 years ago, mostly affecting the Southeast areas of America where there are warm humid climates. You may notice the black streaks or algae is more prominent on the northern side where the roof is darker and wetter. This is ideal for the growth of algae. However climate is not the only thing to blame. About 20 years ago, manufacturers began to use limestone in roof tile. Limestone is a paradise for algae growth. Manufacturers did notice the problem and began to add zinc and copper to inhibit algae growth. However these affects do wear down over time. As the algae begins to grow, it will start off as a blue-green color. The organisms from on the outer coating make this change to protect themselves from the sun rays. Even though the black streaks pose an unsightly problem, they also cause damage to the roof. As the algae grows, it will lock in more moisture in the roof’s tiles. As the algae and fungi grow together, they form lichen.

How Do You Remove Algae, Fungus & Lichen from a Roof?

The lichen roots seep deep into the tile and feed on the minerals inside the tile dissolving it over time. Cleaning lichen can be very difficult once the algae and fungus reaches this point. Some may try to scrub it off or dry the lichen out. This is a temporary fix however, as with the first sign of rain, the algae will spark and start back to life. Your next option is to have your roof cleaned. In fact, at the first hint that algae is starting to develop, you’ll want to have your roof cleaned. This is something you don’t want to hesitate on as postponing lichen removal can lead to premature roof replacement. Keeping the algae in check will help you avoid the expensive cost of having your roof replaced.
