    Algae cause black streaks on the roofs of many homes or businesses across the United States. Commonly found in warm, humid areas, algae may not damage your roofing, but it certainly compromises its aesthetic appeal.

    The algae discoloration often begins as small spots that quickly transform into dark streaks on your roof. By the time you notice algae growing on your roof, it likely has been present for several months or longer. We recommend hiring a professional to remove algae from your roof, but you may opt to do it on your own.

    DIY Option

    If you decide to remove algae on your own, a mix of household bleach and water should do the trick. This method involves spray washing the roof with a 50:50 mixture of water and liquid chlorine bleach. Once you spray the solution on the roof, give it about 15 to 20 minutes to kill the bacteria before rinsing thoroughly with low-pressure water.

    You may have to let the solution sit a bit longer, but don’t let it dry completely as this may hinder thorough rinsing. Take extra caution to protect surrounding plants and areas from the water and bleach solution. Additionally, never use a pressure washer for roof cleaning as it may damage and shorten the life of your roof.

    Steps to Discourage Algae Growth

    Roof algae thrive in wet and humid conditions. You can stop the growth from starting in the first place, effectively making your roof last longer. The following tips can help you prevent future growth once you’ve safely removed algae from your roof:

    • Minimize debris accumulation and trim tree branches to allow more sunlight to reach the roof.
    • Maintain clean gutters to promote proper water drainage.
    • Invest in regular roof cleaning as part of routine property maintenance.
    • Install asphalt shingles with algae-resistant technology.
    • Add zinc or copper strips to your roof to discourage algae growth.
    • Minimize standing water on the roof by fixing shingles and performing minor roof repairs as necessary.

    All these suggestions revolve around the idea that keeping things clean and organized ultimately prevents algae growth and improves your roof’s lifespan.
