Fasto Roofing explores the causes and solutions for algae growth on roofs, emphasizing the importance of prevention and maintenance to protect your home.
Understanding Algae on Roofs
What is Algae?
Algae: Aquatic, photosynthetic organisms without leaves, stems, or roots.
Growth: Algae spores in the air land on rooftops, latch onto asphalt shingles, and feed on the limestone granules.
Why is Algae Undesirable?
Damage: Algae weaken shingles by eating away at the limestone.
Spread: Algae can combine with fungus to form lichen, which is more destructive.
Benefits of Algae-Free Roofing

Maintaining an Algae-Free Roof
Cleaning and Prevention
Cleaning Solution: Use a mixture of half household bleach and half water to remove algae.
Preventive Measures: Insert copper or zinc strips under shingles along the roof peak to minimize algae growth.
Best Practices
Dark Shingles: If algae-free roofing is not an option, dark-colored shingles can help hide algae stains.
Gutter Maintenance: Keep gutters clean to prevent moisture buildup, which promotes algae growth.
