How To Remove Algae From Roof? Learn From the Experts at Cajun Softwash
If you have algae on your roof and are looking for a solution to get rid of it, you're in the right place. We at Cajun Softwash specialize in soft washing houses and commercial properties throughout Louisiana. Roof algae might appear like a mere cosmetic issue—but if not treated, it can do real harm.
Spotting the Difference: Algae, Moss, or Mould?
Just before you attempt any solution, you must identify what you're actually dealing with.
Roof Algae appears as black streaks flowing down your shingles. It's flat and grows rapidly in wet, shaded regions. Birds, wind, and other wildlife bring the spores to your roof. The ARMA says that algae can destroy shingles by holding moisture.
Moss is thick and green. It creates fuzzy patches and grows best under overhangs of trees. It retains water, which gradually weakens shingles.
Mould is usually a consequence of untreated algae. It has a dark, slimy appearance. Better still, it can begin to rot the roof's underlayment.
Simple DIY Steps on How to Remove Algae
If small patches of algae, use these home solutions:
Bleach and Water Solution Combine water and bleach (50/50) in a spray bottle. Spray the area. Let it sit for 15–20 minutes. Then, rinse off gently with a garden hose. Wear gloves and cover nearby plants.
Vinegar and Water Mix Mix equal parts water and vinegar. It's not as harsh but great for the earlier stages of algae. Rinse thoroughly again.
Steer clear of high-pressure washing. It may look efficient but can invalidate your roof warranty or shed shingles.
Prevent Future Algae Growth
Trim Trees: Remove branches near your roof to minimize shade and spore transmission. Dry Roof, Clean Gutters: Standing water is algae's closest ally. Install Zinc or Copper Strips: These metals kill spores of algae when it rains. Consider Algae-Resistant Shingles: They're infused with copper granules to protect for years to come.
