How to Protect Your Asphalt Roof from Moss and Algae Growth

Solarshield has been serving homeowners in Altoona and across Central Pennsylvania since 1978, providing trusted roofing solutions designed to withstand all four seasons. With our extensive experience in asphalt roofing, we are aware of the common issues that can compromise the longevity and performance of your roof, including moss and algae growth. These natural nuisances might seem harmless at first, but over time, they can seriously damage your shingles and your home’s curb appeal.

Why Moss and Algae Growth Pose a Problem for Roofs

Understanding the difference between moss and algae is the first step to prevention:

Algae appears as dark, streaky stains across the roof, typically blue-green in color. It’s more of a cosmetic issue, but it thrives in humid, shaded environments and can stain your roof over time.

Moss, on the other hand, is thick, green, and spongy. It can grow between shingles and lift them, trapping moisture and making your roof more vulnerable to leaks and decay.

Consequences of Moss and Algae Growth:

• Reduced curb appeal and home value
• Shortened roof lifespan due to shingle deterioration and moisture retention
• Increased risk of leaks and costly repairs if left untreated

These issues can go from minor to serious quickly, especially in Pennsylvania’s moisture-rich climate.

Moss and Algae Prevention Tips for Roofs

Prevention is always easier and more cost-effective than repair. Here are simple, proven ways to keep your roof clean and algae-free:

• Trim Overhanging Trees: Sunlight helps dry out your roof. Removing overhanging branches reduces shade and keeps debris from collecting.
• Regular Roof Cleaning: Use a leaf blower or soft broom to remove leaves and twigs that trap moisture and create an ideal environment for moss growth.
• Clean Gutters: Blocked gutters can lead to water backing up under the shingles, especially near the roof’s edge, so it’s important to keep them flowing freely.
• Improve Roof Ventilation: A well-ventilated attic reduces moisture and condensation inside your home, making your roof less hospitable to growth.
• Install Zinc or Copper Strips: These metal strips release algae-inhibiting ions when it rains. They’re especially useful on shaded roofs and can be installed with a new roof or retrofitted to an existing one.
• Maintain Proper Drainage: Ensure your roof allows water to flow off easily and efficiently. Pooling water is a red flag and a fast track to moss and algae growth.

Algae-Resistant Roofing Solutions

If your roof is due for replacement, now’s the time to think long-term. Solarshield installs high-quality asphalt shingles from Owens Corning®, which offer shingles made with algae-resistant copper granules to inhibit growth over time. These shingles provide long-lasting protection and help maintain the appearance of your roof for years, making them a smart investment for Pennsylvania homeowners.
