Best Algae Resistant Shingles For Your Roof

When it comes to protecting your home, you may not think about the shingles on your roof as needing protection. But did you know that something as simple as algae growth can cause serious damage to your roof, leading to costly repairs or even the need for a full replacement?

Here at A. Fricker Roofing & Waterproofing, we believe that prevention is key, and that’s why we want to discuss the importance of algae resistant shingles. Not only do they add an extra layer of protection to your roof, but they can also give your home a fresh and clean look.

What Causes Algae Growth On Roofs In The First Place? 

Algae thrive in warm, humid environments, and can easily spread to roofs via airborne spores. This means that homes in areas with high humidity and heavy rainfall are at a higher risk of algae growth on their roofs.

So, How Can You Protect Your Roof From Algae Damage? 

The answer is by installing algae resistant roof shingles. These shingles have an added layer of protection, often in the form of copper or zinc granules, that act as a barrier to prevent algae growth.

In this article, we’ll take a closer look at the different types of algae resistant shingles available, their pros and cons, and tips on choosing the best shingles for your home. Together, we’ll make sure that you’re informed and empowered to make the best decision for your roof.

What Are Algae Resistant Shingles?

Algae resistant roof shingles are a special type of shingle that is designed to prevent the buildup of algae on your roof. They look similar to traditional shingles and often have an asphalt appearance, but they are made differently.

One of the key components of algae resistant shingles is their copper granules. Copper is an effective barrier against algae growth because it makes the materials in the shingle inedible to algae, which typically feed off the limestone present in regular asphalt shingles. This is why copper is also used in many household items, such as containers, sinks, and basins.

When it comes to algae resistant shingles, the shingle features may vary from one manufacturer to another. However, there are some commonalities that many of these shingles share.

  • Prevent the growth of moss, mildew, and algae
  • Protect your roof from stains
  • Antimicrobial properties are used in composite construction.
  • Preventing the formation of streaks
  • Increase the curb appeal of your house 

Many algae resistant shingles are also available in various styles, offering flexibility in your home improvement options. With an algae resistant roof, you can be sure that your home will be well-protected, energy efficient, and visually pleasing.

When it comes to choosing the best algae resistant shingles for your roof, there are a few key factors to consider.

Additionally, CertainTeed offers a limited warranty on this technology for a period of 10-15 years.

2. GAF Time-Released StainGuard Plus

Another great option is GAF’s Time-Released StainGuard Plus. This technology uses specialized engineered capsules that release copper over time, creating a continuous coating. GAF offers a 25-year warranty on shingles that use this technology, including their popular Timberline HDZ shingles.

3. Atlas Algae Resistant Shingles

Atlas algae resistant shingles are another popular choice. They come with a Lifetime Warranty on their algae resistant shingle technology that incorporates Scotchguard 3M, which boasts copper-laden granules, zinc, and magnesium, which are also algae resistant.

4. Owens Corning StreakGuard™ Algae Resistance Protection

Owens Corning’s StreakGuard™ algae resistance protection is a reliable option as well, as it helps inhibit the growth of algae, preserving the beauty of your home. This option comes with a 25-year Algae Resistance Limited Warranty on certain shingle lines.

5. Malarkey Algae Resistant Shingles

Malarkey algae resistant shingles are the best option for preventing black streaks caused by algae growth. These shingles use 3M copper granules that release copper ions to inhibit algae growth, with a 10% blend of copper granules for maximum protection. They were the first shingle manufacturer to receive the Scotchgard Protector designation, which was bestowed by 3M.

6. PABCO Algae Defender

Finally, PABCO Roofing Products offers premium asphalt shingles with their Algae Defender, which comes with an algae resistance warranty, making it ideal for protecting against black streaks on rooftops caused by algae, particularly in coastal regions or high-humidity areas.

It’s important to note that choosing the best algae resistant shingles for your roof will ultimately depend on your specific needs, budget, and the availability of different brands in your area. That’s why it is recommended to seek the advice of a professional roofing company. They can provide you with the best advice, and options available in your area.

Are Algae Resistant Shingles Worth It?

Whether or not algae resistant shingles are worth it depends on your specific needs and priorities. On the one hand, they can provide valuable protection against unsightly stains, damage, and high energy bills caused by algae growth on your roof. They also can improve curb appeal, and even increase the selling point of your home.

On the other hand, algae resistant shingles come at an additional cost compared to traditional shingles. The approximate cost of basic algae resistant shingles is between $0.75 and $1.00 per square foot, with higher-quality options costing up to $1.50 per square foot. Additionally, installation costs can vary depending on your location, with an average installation cost of around $3.75 per square foot.

In order to determine if algae resistant shingles are worth it for you, it’s important to consider the potential benefits and weigh them against the added cost. It’s also crucial to consider your area’s climate, humidity, and precipitation. It might be worth the investment if your area is more prone to algae growth.
