A Cleaner Roof, a Longer Life: Top Strategies for Preventing and Treating Roof Algae
Maintaining your roof is about more than appearances—it’s essential for prolonging its lifespan and preventing costly repairs. At Exterior Property Experts, we understand the importance of regular roof care, from preventing algae buildup to treating existing streaks.
Understanding Roof Algae and Why It Forms
Roof algae, like Gloeocapsa magma, forms as black streaks on asphalt shingles, feeding on limestone filler in modern roofing materials. This growth is most common in shaded, humid areas where moisture can accumulate. While algae won’t typically damage your shingles immediately, its presence can foster mold, mildew, and lichen, which ultimately harm the roof’s structure.
Top Prevention Techniques
-
Trim Overhanging Branches: Shaded areas with little airflow are prime spots for algae growth. Trimming nearby trees allows sunlight to keep your roof drier, reducing algae’s chance to thrive.
-
Consider Copper or Zinc Strips: Installed along the roof’s ridge, these metals release ions during rain, which hinder algae growth naturally.
-
Routine Cleanings: Having a professional clean your roof every 1-2 years will remove any early signs of algae or moss. Our team uses a gentle softwashing technique to keep shingles intact while fully eliminating algae and dirt.
Why Choose Professional Roof Cleaning
DIY cleaning often involves harsh chemicals or high-pressure washing, which can damage shingles. Our team at Exterior Property Experts uses specialized, eco-friendly solutions tailored for each roof type, ensuring a safe, effective clean that lasts longer and protects your home.
