What are Moss, Algae, and Lichen?
Moss, algae, and lichen are three types of fungi that can grow on roofs. Moss is a type of plant that grows in damp, shaded areas, and it often appears as a green or yellowish mat-like formation. Algae typically appear as a black or green slimy film on the surface of the roof and is caused by high humidity and moisture. Lichen is a combination of an algae and a fungus that typically appears as a crusty white or grayish-green layer on the roof's surface. These organisms can cause significant damage to roofs because they retain moisture and can lead to rot or other structural damage.Additionally, moss and lichen can damage shingles by eroding them or causing them to become brittle. As a result, it is important to remove moss, algae, and lichen from the roof in order to keep it in good condition.
Risks Associated with Removing Moss, Algae, and Lichen
