Gloeocapsa magma is possibly one of the most widespread of numerous algae types that contribute to discoloration. All varieties are delivered with the air, and tend to gather and expand upon roofing frameworks. Natural pigments created by these algae might trigger a white or light colored roof to gradually become dark brown or black. Discoloration may look like uniform discolorations or streaks. The algae discolorations should not be mistaken for moss or tree droppings, which typically produce only local stains.
This kind of roof discoloration has been most extensive in the Gulf States, particularly Labelle and along the Northwest and Eastern Seaboards. It is not, however, confined exclusively to these areas.
Algae growth strikes varying levels in all regions of the nation, specifically those subjected to warm, humid climates. It ought to be noted that almost all kinds of roof are susceptible to algae discoloration. It is, of course, most obviously visible on light colored roofs, while it is not so visible on darker shades of roof. Algae discolorations are challenging to remove from roofing surface areas, yet might be lightened by applying a solution of liquid household chlorine bleach (sodium hypochlorite) and water. Instructions for mixing solutions of these active ingredients might vary between roof shingles suppliers and depend on the extent of discoloration.
A regular solution must be one part chlorine bleach and one part water. Various other cleansing chemicals or approaches must not be utilized without authorization of the roof shingles manufacturer.

Avoid scrubbing the surface, as this friction might loosen up and remove roof granules. If possible, always apply this solution from a ladder and/or scaffolding to avoid straight contact with the roof surface. Observe all possible security preventative measures when dealing with or near the roof. The formula must be left on the roof for at the very least 15 mins but for no greater than 20 mins.
Lastly, wash the solution off the roof by gently spraying the surface with water. Be alerted that this solution application and rinse process will make the roof surface unsafe and potentially dangerous to step on throughout the process. The performance of a cleaning strategy is just short-lived, and discoloration will likely repeat.
Nevertheless, numerous sorts of algae resistant roofing products have been developed and are now commercially offered. These asphalt roof products are especially made to inhibit algae development for extended periods of time.
