The Destructive Nature of Lichen on Metal Roofs, Gutters and Concrete

What is Lichen

Lichen is a slow growing plant that grows on roofs, rocks, concrete, walls and trees. Lichen grows with two other organisms, algae and fungus. They actually feed each other, or create food for each other, allowing them to grow. Lichen can be very destructive, eating away at concrete driveways, sidewalks etc and leaving holes where they existed. It can also eat the paint off of gutters and metal roofs. This damage is irreversible and will be an expensive repair.

How to Prevent Lichen

The best way to prevent lichen from causing damage is to have your home regularly cleaned. Lichen can be hard to kill but by keeping algae and fungus from starting to grow on your home or concrete surfaces, you can prevent lichen from starting. Having your metal roof and gutters sprayed with hydrogen peroxide and then scrubbed clean on a regular basis will prevent this damaging lichen from starting to grow. Likewise, having your concrete pressure washed regularly will prevent lichen from growing on the concrete and eating holes in your driveway and sidewalk, permanently damaging your property.
