Dirt, dust, and leaves are not the only thing that dirties your roof. Your roof can also develop something more unattractive- algae. A lot of times, house owners misinterpret algae for roof mold. Roofs develop several kinds of algae, lichen, fungi, etc., with time.

What is roof algae? 

Roof algae usually appear as some kind of roof discolouration. The algae that you see on your roof is the blue-green type of algae. It leaves black, mold-like stains on your roof when it dies. It can also cause green mossy growths and ugly streaks in your roof.

They will only worsen if you don’t hire professionals to get rid of it. Roof algae can look like mold. However, they are not the same. When you see the following, it is most likely to be algae:

  • Black stains or streaks
  • Green mosses
  • Lichens
  • Green or white spots.

Algae can cover your roofs in just a matter of four years or less. You will quite often find algae in a climate with humid or warm atmospheres. 

What does algae do to your roof?
