Fasto Roofing explains the necessity and benefits of algae-free roofing, especially in climates with unexpected weather changes and high humidity.
Why Algae-Free Roofing Is Needed
The Problem with Algae
Appearance: Algae, officially known as Gloeocapsa Magma, causes dark, ugly streaks on roofs, affecting the curb appeal.
Damage: Algae eats away at shingles, weakening them and inviting further damage from fungi, mildew, and mold.
Benefits of Algae-Free Roofing
Maintains Appearance: Keeps the original color of your shingles, enhancing curb appeal.
Energy Efficiency: Prevents algae from blocking the reflectiveness of shingles, reducing energy costs.
Prevents Moss Growth: Stops roots from spreading under shingles, preventing water penetration and further roof damage.
The Impact of Algae on Roofs
Algae vs. Mold
Algae: A plant-like organism that feeds on limestone in shingles.
Mold: A fungus that requires nutrients, often derived from algae, to grow.
Growth Conditions
Ideal Conditions: Heat, moisture, and nutrients (limestone in shingles) promote algae growth.
Airborne Spores: Algae spreads through airborne spores, thriving in shaded and humid environments.
Types of Algae
Gloeocapsa Magma: The primary type of algae that affects roofs, turning black as it spreads.
Preventing and Cleaning Algae
Routine Maintenance
Power Washing: Regularly power wash your home and roof to remove debris that fosters algae growth.
Sunlight Exposure: Trim trees to allow more sunlight to reach your roof.
Algae-Resistant Shingles
Warranty: Algae-resistant shingles come with warranties ranging from 5 to 20 years, extending the lifespan of your roof.
Conclusion
Choosing algae-free roofing materials can protect your roof from damage and maintain its appearance.
