What is this green stuff that can be seen on my roof? 

Algae, which has a scientific name Gloeocapsa magma, is not actually an alga but cyanobacteria. However, in this article, we will be referring to this contaminant found on your roof as algae due to its color (green).  

While the algae fodders in your shingles’ limestone, it retains a black residue, streaking down your roof. Once algae are left untreated for a sufficient time, it could cause the granules of your roof shingles to separate, which will eventually require replacement. 

Ways to eliminate algae from the roof 

DIY removal 

You can remove the black streaking, neutralize and eliminate algae off using bleach. But keep in mind that you should only do this at your own risk. Bleach is dangerous and corrosive to pets and plants. You must dilute it before applying and you need to rinse down your plants as well. Aside from that, your home should have the right place for the chemicals to be drained properly. Not to mention, you need to use and climb high up using a ladder as you treat a roof. Given the several dangers stated, it would be much recommended to leave this work to the experts and hire a professional cleaner to do exterior house washing, especially on your roof. 

Hire an expert to treat your roof
