Option Two: Oxygen Bleach
For those against using straight household bleach, oxygen bleach is another alterative in eliminating algae stains. Oxygen bleach uses hydrogen peroxide versus sodium hypochlorite as an oxidizer. The result comes in liquid or powdered form for an eco-friendlier choice.
Once mixed with water, the power or liquid eliminates all foreign specimens without taking the color out of your shingles. In addition, it doesnt affect the vegetation surrounding your home. Using a pump sprayer, spray the solution on the roof continuously for 10 or 15 minutes. The oxygen bleach attacks the roof algae directly and begins to take the stains away.
After the allotted time, take a scrub brush and lightly scrub the shingles. Apply more solution while you work for a deeper clean and hose off the roof once finished. If needed, repeat the previous steps until the stains are gone.
