Gloeocapsa magma is most likely the most common of several algae types that add to discoloration. All species are transferred via the air, and have a tendency to accumulate and grow upon roof structures. Natural pigments created by these algae may trigger a white or light tinted roof to slowly turn dark brown or black. Discoloration may appear as regular discolorations or streaks. The algae stains ought to not be confused with moss or tree sap, which commonly produce only local discolorations.
This kind of roof discoloration has actually been most prevalent in the Gulf States, particularly Punta Gorda Isles and along the Northwest and Eastern Seaboards. It is not, however, restricted solely to these areas.
Algae growth occurs to varying levels in all regions of the country, specifically those subjected to warm, moist conditions. It must be noted that mostly all kinds of roofing systems are prone to algae discoloration. It is, of course, most readily visible on light color roofs, while it is not so visible on darker tones of roofing. Algae discolorations are difficult to remove from roofing surfaces, yet might be lightened by using a solution of household chlorine bleach (sodium hypochlorite) and water. Instructions for blending solutions of these ingredients may differ between roof shingles producers and depend on the extent of discoloration.
A typical recipe must be one part chlorine bleach and one part water. Other cleansing chemicals or approaches must not be made use of without approval of the roof shingles supplier. First, delicately spread this solution on the roof covering surface. Use regular safety measures for handling bleach consisting of eye goggles and rubber gloves.

Make sure to apply it thoroughly to prevent damages to various other parts of the structure and the bordering landscape. Stay clear of scrubbing the surface, as this friction may loosen up and get rid of roof granules. Ideally, you should apply this solution from a ladder and/or scaffolding to avoid straight contact with the roof surface. Observe all possible safety preventative measures when dealing with or near the roof. The formula should be left on the roof for at least 15 minutes however, for no more than 20 minutes.
Lastly, rinse the solution off the roof by carefully splashing the surface with water. Be cautioned that this solution application and rinse process will make the roof surface area slippery and possibly dangerous to walk on during treatment. The effectiveness of a cleaning strategy is only momentary, and discoloration will likely reoccur.
Nonetheless, several types of algae resistant roof covering items have recently been created and are currently commercially offered. These asphalt roof items are especially developed to inhibit algae growth for extended periods.
Caution!
High pressure cleaning systems will very likely harm asphalt roof shingles and should not be directed to asphalt roof for getting rid of algae or for any other roofing application.
