Growth Conditions: Thrives in humid environments, feeding on heat and moisture, especially in damp, shady areas.
Why Algae Thrives on Asphalt Shingles

Spore Spread: Algae spores can be blown onto your roof from nearby areas, such as trees or neighboring roofs.
Consequences of Algae Growth
Aesthetic Impact: Creates dark, unsightly stains on the roof.
Material Damage: Algae can weaken shingles and invite further issues like fungi, mold, and lichens.
Preventing Algae Growth
Regular Maintenance
Tree Trimming: Keep trees trimmed back to allow more sunlight to reach the roof.
Gutter Cleaning: Ensure gutters are cleaned regularly to prevent moisture buildup.
Cleaning Algae
DIY Cleaning Solution: Mix one part liquid chlorine bleach with one part water, spray on the roof, let it sit for 15-20 minutes, then rinse with low pressure.
