The Importance of Choosing the Right Shingles for Your Roof and Hiring a Certified Roofer to Prevent Streaking and Algae Growth

When it comes to protecting your home, your roof plays a crucial role in ensuring its longevity and keeping it safe from the elements. One of the most important decisions homeowners face is selecting the right type of shingles for their roof. However, choosing the right product is only part of the equation. Hiring a certified roofer is essential to ensuring that your shingles are installed properly, preventing issues like algae growth, streaking, and premature wear. In this blog, we’ll discuss the different types of shingles, why it’s important to hire a certified roofer, and how proper installation can prevent algae buildup and streaking.

Types of Shingles for Your Roof

There are a variety of shingle types to choose from when installing or replacing your roof. The type you select will depend on several factors, including climate, aesthetic preferences, and budget. Here are the most common types of shingles used for residential roofing:

1. Asphalt Shingles

Asphalt shingles are the most commonly used roofing material in the United States due to their affordability, durability, and ease of installation. They are made from a fiberglass base coated with asphalt and topped with granules that provide color and texture.

Benefits of Asphalt Shingles:

  • Affordable: Asphalt shingles are one of the most budget-friendly options for homeowners.
  • Variety: Available in many colors, styles, and designs to complement your home.
  • Durability: Resistant to harsh weather conditions, such as rain, wind, and snow.

However, one downside of asphalt shingles is their tendency to streak or develop algae growth over time. This is why it’s crucial to install high-quality shingles and ensure proper installation by a certified roofer.

2. Architectural Shingles

Architectural shingles, also known as dimensional shingles, are a step up from traditional asphalt shingles. These shingles are made from multiple layers of material, which gives them a thicker, more textured look.

Benefits of Architectural Shingles:

  • Aesthetic Appeal: These shingles provide a more upscale and dimensional look, enhancing the curb appeal of your home.
  • Longer Lifespan: Due to their increased thickness, architectural shingles last longer than traditional asphalt shingles (typically 30 to 50 years).
  • Weather Resistance: They offer better resistance to high winds and other weather elements.

While architectural shingles are more durable, they can also be prone to algae growth and streaking if not installed properly.

3. Wood Shingles

Wood shingles are another option for homeowners looking for a natural aesthetic. Made from materials like cedar or redwood, wood shingles provide a rustic and charming look to homes.

Benefits of Wood Shingles:

  • Natural Look: Perfect for homeowners who want a traditional or eco-friendly look.
  • Eco-Friendly: Wood shingles are biodegradable and made from renewable resources.
  • Insulation: Wood provides natural insulation, helping to maintain the temperature inside your home.

However, wood shingles require more maintenance and can be susceptible to moisture damage, mold, and algae growth if not treated properly. This is why choosing the right installation method and ensuring the shingles are sealed properly is essential.

4. Metal Roofing

Metal roofing, which can come in panels or shingles, is gaining popularity due to its longevity, energy efficiency, and modern aesthetic. Metal roofs can last up to 50 years or more and are resistant to fire, wind, and snow.

Benefits of Metal Roofing:

  • Long-Lasting: Metal roofing can last up to 50 years with minimal maintenance.
  • Energy Efficiency: Metal roofs reflect sunlight, which can help reduce energy costs by keeping homes cooler in the summer.
  • Durability: Metal roofs are highly resistant to extreme weather conditions.

Metal roofs are less likely to experience algae growth and streaking compared to asphalt or wood shingles, making them an excellent option for those looking for a low-maintenance roofing solution.


Why It’s Important to Hire a Certified Roofer

When it comes to installing your new roof, selecting the right shingles is only half the battle. A critical part of the process is hiring a certified roofer who is trained to properly install your roofing materials. Here’s why hiring a certified professional is essential:

1. Proper Installation Prevents Streaking and Algae Growth

Algae growth and streaking are common issues that many homeowners face, especially in areas with high humidity or frequent rainfall. Asphalt shingles, in particular, are prone to algae growth, which can result in unsightly black streaks or stains. This growth occurs when algae feed on the limestone in the shingles, causing discoloration.

Certified roofers understand how to install shingles properly to reduce the likelihood of algae growth. They may use algae-resistant shingles, install the roof with adequate ventilation, and ensure that all components, like flashing and underlayment, are properly installed to prevent moisture buildup. Proper installation will also ensure that your shingles are tightly secured, which reduces the likelihood of water seeping under the shingles and promoting algae growth.

2. Choosing the Right Shingles for Algae Resistance

There are roofing materials specifically designed to resist algae growth, which is a key consideration for Cleveland or other humid regions. For example, many modern asphalt shingles are manufactured with copper or zinc granules that inhibit the growth of algae. A certified roofer will know which shingles are best suited to your specific climate and how to ensure your roof is protected from algae.

Additionally, a certified roofer understands the importance of choosing shingles that are treated for algae resistance, as this will ensure your roof remains clean and free from unsightly streaks. Many roofing manufacturers now offer algae-resistant options that include built-in features to prevent the growth of algae, which can ultimately save you money in maintenance and repairs.

3. Ensuring Proper Ventilation

One of the leading causes of algae and streaking is improper roof ventilation. If your attic space is not adequately ventilated, it can lead to increased moisture levels in the roof, providing a perfect environment for algae growth. Certified roofers are trained to assess your home’s ventilation system and ensure that it meets the proper standards. This can significantly reduce the risk of algae growth and extend the lifespan of your shingles.

4. Warranties and Guarantees

Hiring a certified roofer ensures that you will receive the manufacturer’s warranty on the roofing products used and a service warranty for the installation. This means that if there are any issues with your roof, you can have peace of mind knowing that the installation is covered under a guarantee. This is especially important when it comes to issues like algae growth and streaking, which can be costly to fix if not properly addressed by a certified professional.


How to Prevent Streaking and Algae Growth on Your Shingles

In addition to hiring a certified roofer, there are several steps you can take to prevent streaking and algae growth on your shingles:

  1. Install Algae-Resistant Shingles: Opt for shingles that are specifically designed to resist algae growth. Many manufacturers now include copper or zinc granules in their shingles, which help prevent algae buildup.
  2. Maintain Proper Ventilation: Ensure that your attic and roof have proper ventilation to prevent moisture buildup, which can promote algae growth. A certified roofer can assess your home’s ventilation system to ensure it is adequate.
  3. Regular Roof Cleaning: If you notice streaks or algae growing on your shingles, it’s important to have them cleaned regularly. This can be done by using a soft wash method or a cleaning solution that won’t damage the shingles.
  4. Trim Nearby Trees: Trees can contribute to the accumulation of moisture on your roof by blocking sunlight and allowing moss and algae to thrive. Trim back branches that overhang the roof to reduce the amount of moisture retained by the shingles.
  5. Choose the Right Roof Pitch: Roofs with a steeper pitch tend to shed water more effectively, reducing the chances of algae growth. If you’re in the process of installing a new roof, discuss your roof pitch with your roofer to ensure it’s ideal for your home’s climate.

Conclusion

Choosing the right shingles for your roof is a critical decision that can affect your home’s appearance, durability, and protection. However, proper installation by a certified roofer is just as important in ensuring that your shingles perform optimally. A certified roofer will not only ensure that your roof is installed correctly but also take steps to minimize the risk of streaking and algae growth, which can detract from your home’s curb appeal and longevity.

By investing in high-quality shingles, hiring a certified roofer, and taking steps to protect your roof from algae and streaking, you can enjoy a beautiful, durable roof that will protect your home for many years to come.
