The Best Way To Remove Algae From Your Roof and Siding…

Roof stains or discoloration is caused by a type of algae that collects on all types of shingles. The algae will break down the life of your roof. The presence of algae is not only unattractive but can become a costly headache. 

What are algae?

Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping, including species from multiple distinct clades. Gloeocapsa magma is the scientific term for the algae on your roof. In this article, we will be calling it algae because that is what most people know it due to its green color. The algae feed on the limestone in your shingles. This causes those unsightly big black streaks on your roof. Not only are they ugly but they will in time destroy your shingles that will require you to replace the roof.

Where do the algae on your roof come from?

The algae spread by releasing spores into the air. Those spores usually require a moist surface to open. If the moist surface they land on is your roof, that’s where they bloom. The algae spiked in the 1990s because of the rising humidity form climate change. Around this same time roof, manufacturers were switching shingle filler from paper to a cheap, but algae-attracting limestone filler. Algae colonized typically on the north side of the roof where there is a lack of sunlight. Algae is most common in areas that have a cool and moist climate. Algae can also be seen on siding and on other areas of a home’s exterior. Algae spores blow from the roof to roof and as the spores land on the roof, the dark areas shorten your roof’s lifetime. Algae can be neutralized with the correct treatment.
Removing the algae off your roof yourself: The DIY solution is to spray wash the roof with a 50 percent mix of water and bleach to get rid of the algae. Just be sure to wet your foundation plantings first, and rinse everything in clean water when you’re done. Plants don’t like bleach, and wetting them with plain water first protects them. Also, your home needs a proper place to drain chemicals.
