Why is Moss Bad for Asphalt Shingles?

Moss might look picturesque on your roof, but it’s a serious problem for asphalt shingles. Here’s why:

Water Retention

Moss acts like a sponge. When it rains, moss absorbs and retains water. This creates a consistently wet environment on your roof, which is bad news for your shingles. Constant moisture can lead to:

• Mold and Mildew Growth: A wet roof is a perfect breeding ground for mold and mildew, which can spread to other parts of your home.
• Shingle Degradation: Prolonged exposure to moisture can weaken and degrade your shingles over time, making them less effective at protecting your home.

Shingle Degradation

Moss doesn’t just sit on top of your shingles—it can grow roots that penetrate and damage them. Over time, this can lead to:

• Cracked or Broken Shingles: Moss roots can cause shingles to crack or break, compromising the integrity of your roof.
• Granule Loss: The roots can also dislodge the granules that protect your shingles from UV rays, leading to faster wear and tear.

Drainage Interference

Proper water drainage is crucial for maintaining the health of your roof. Moss can interfere with this by:

• Blocking Water Flow: Moss can trap water, preventing it from flowing off the roof and into the gutters. This can cause water to pool on your roof, leading to leaks and other water damage.
• Clogging Gutters: Pieces of moss can break off and clog your gutters, which can cause water to back up and overflow, potentially damaging your home’s exterior and foundation.

Potential Leaks

One of the most serious consequences of moss growth is the potential for leaks. Moss can lift shingles away from the roof deck, creating gaps where water can seep in. This can lead to:

• Interior Water Damage: Leaks can cause water damage to your home’s interior, including ceilings, walls, and insulation.
• Structural Damage: Over time, water infiltration can weaken the structural components of your roof and home, leading to expensive repairs.

Take Action Now

If you spot moss on your roof, it’s crucial to take action before it leads to more severe problems. For effective asphalt shingle moss removal, consider using moss-specific cleaners and follow up with preventive measures like installing zinc or copper strips.

How to Remove Moss from Asphalt Shingles

Removing moss from your asphalt shingle roof is essential to maintain its integrity and longevity. Follow these steps carefully to ensure effective removal with minimal damage to your shingles.

Materials You’ll Need

• Garbage Bag: For collecting moss and debris.
• Garden Hose: For rinsing the roof.
• Ladder: Ensure it’s sturdy and familiarize yourself with ladder safety.
• Moss-Specific Cleaner: Choose a cleaner that does not use harsh chemicals like bleach.
• Homemade Cleaner Mix: If you prefer a DIY solution, mix 1 part dish soap with 2 parts water and 1/2 part bleach.
• Sprayer: For applying the cleaning solution.
• Soft, Long-Handled Scrub Brush: Optional, for gently scrubbing off moss.

Step-by-Step Removal Process

Safety Precautions

1. Safety First: Always prioritize safety. Use a sturdy ladder and consider wearing a harness. Ensure the roof is dry to avoid slipping.
2. Protective Gear: Wear work boots, thick pants, and gloves. Having another person to assist can improve safety.

Necessary Materials

Gather all the materials listed above and keep them within reach. Make sure your ladder is on a stable surface and your garden hose is long enough to reach the affected areas.

Step-by-Step Guide

1. Spray Cleaner: Using your sprayer, apply the moss-specific cleaner or homemade solution generously on the moss-covered areas. Ensure you cover all the moss.
2. Wait Time: Allow the solution to sit for 15-20 minutes. This helps to loosen the moss and makes it easier to remove.
3. Low-Pressure Rinse: Rinse the area with a garden hose on low pressure. Avoid using a pressure washer as it can damage the shingles. Direct the water flow downward along the angle of the roof to dislodge the moss without lifting the shingles.
4. Manual Removal: If moss remains, use a soft, long-handled brush to gently scrub it off. Work from the top down to avoid lifting the shingles. Be careful not to scrub too hard, as this can remove the protective granules on the shingles.
5. Collect Debris: Place the removed moss and debris into a garbage bag for disposal. Secure the bag to the ladder to keep your hands free for climbing.
6. Flush the Area: Rinse the roof again to ensure all remnants of the cleaner and moss are washed away. This step is crucial to prevent any potential damage to the shingles.
7. Professional Consultation: If some moss is too ingrained to be removed by hand, consult a professional roofer. They can provide advice on the next steps without risking damage to your roof.

Additional Tips

• Regular Inspections: Inspect your roof regularly to catch moss growth early.
• Preventive Measures: Install zinc or copper strips near the ridge of the roof to inhibit future moss growth. Trimming overhanging branches can also reduce shade and moisture, making it less hospitable for moss.

Methods to Avoid When Removing Moss

When it comes to asphalt shingle moss removal, certain methods can do more harm than good. Here are some techniques you should avoid:

Scrubbing

While it may seem like a good idea to scrub the moss off your roof, this method can be quite damaging. Using a hard-bristled brush or scrubbing too vigorously can:

• Remove Protective Granules: Asphalt shingles have granules that protect them from UV rays and weather damage. Scrubbing can dislodge these granules, reducing the lifespan of your shingles.
• Lift Shingles: Aggressive scrubbing might lift or damage shingles, leading to potential leaks.

Instead, use a soft, long-handled brush and work gently from the top down to avoid lifting the shingles.

Pressure Washing

Pressure washing is another method that might seem effective but can cause significant damage:

• High Pressure: The intense force of a pressure washer can strip away the granules on asphalt shingles, leading to premature aging and reducing their effectiveness.
• Lift Shingles: Just like with scrubbing, the high pressure can lift and damage shingles, making your roof more susceptible to leaks.

As noted in Forbes, “Never use a pressure washer to clean an asphalt shingle roof as this will cause granule loss and very likely premature failure of the roof system.”

Harsh Chemicals

Using harsh chemicals like bleach can be tempting because they kill moss quickly. However, these chemicals can:

• Damage Shingles: Bleach and other harsh chemicals can break down the asphalt in shingles, leading to deterioration.
• Harm Surrounding Vegetation: Runoff from these chemicals can damage your lawn, plants, and any other vegetation around your home.

Instead, opt for a moss-specific cleaner or a homemade solution of water and vinegar, which is less harmful to your shingles and the environment.

Warranty Voidance

Using improper methods can void your roof’s warranty:

• Manufacturer Guidelines: Many shingle manufacturers specify that using pressure washers or harsh chemicals will void the warranty. Always check the warranty terms before proceeding with any moss removal method.
• Professional Advice: When in doubt, consult a professional to ensure that your moss removal process complies with warranty guidelines.

By avoiding these methods, you can effectively remove moss without compromising the integrity of your asphalt shingles. For more information or to schedule a consultation, fill out our contact form or call us at (800) 914-4108.

Preventing Moss Growth on Your Roof

Preventing moss from growing on your roof is crucial for maintaining the longevity of your asphalt shingles. Here are some effective methods to keep your roof moss-free.

Installing Metal Strips

Metal strips are a long-term solution for preventing moss growth. Copper and zinc strips are particularly effective. When installed, rainwater washes off small amounts of these metals, which inhibit moss growth.

Copper Strips

Copper strips are a popular choice due to their effectiveness. They oxidize and release copper ions that prevent moss from taking hold.

Zinc Strips

Zinc strips work similarly to copper strips. They release zinc particles when it rains, which creates an environment hostile to moss.

Installation Benefits

• Longevity: Metal strips can last for many years, providing a long-term solution.
• Effectiveness: Both copper and zinc are highly effective at preventing moss growth.
• Minimal Maintenance: Once installed, they require little to no maintenance.

To install, place the strips just below the top ridge of the roof on both sides. Ensure the strips overlap by at least one inch for continuous coverage.

Regular Roof Maintenance

Regular maintenance is essential for preventing moss growth. Here are key steps to include in your routine:

Shade Reduction

Moss thrives in shady areas. Trim back any overhanging branches to increase sunlight exposure on your roof. This simple step can significantly reduce moss growth.

Algae-Resistant Shingles

Consider installing algae-resistant shingles when it’s time for a roof replacement. These shingles contain copper granules that inhibit algae and moss growth.

Regular Inspections

Schedule professional inspections at least once a year. Regular inspections can identify potential issues before they become major problems.

Gutter Cleaning

Keep your gutters clean to ensure proper water drainage. Clogged gutters can cause water to back up, creating a moist environment conducive to moss growth.

Debris Removal

Remove any debris that accumulates on your roof. Leaves, twigs, and other debris can trap moisture, providing a perfect breeding ground for moss.

By following these preventative measures, you can keep your roof moss-free and extend the life of your asphalt shingles. For more information or to schedule a consultation, fill out our contact form or call us at (800) 914-4108.

Should You Remove Moss-Covered Shingles Before Installing a New Roof?

When it comes to installing a new roof, removing moss-covered shingles is a step you shouldn’t skip. Here’s why:

Roof Condition Assessment

Before installing a new roof, it’s crucial to assess the condition of your current roof. Severe moss growth can compromise the quality of your decking and underlayment. The only way to know for sure is to remove the shingles and inspect these layers. Ignoring this step can lead to major issues down the road, such as damaged underlayment that interferes with your new shingles’ performance.

Potential Problems

If you install new shingles over moss-covered ones, several problems can arise:

• Bumps and Dips: Damaged decking and moss growth can create an uneven surface, making proper water drainage difficult. This can also reduce your home’s curb appeal.
• Safety Risks: Moss is slippery and can make it dangerous for roofers to work, increasing the risk of falls.
• Secondary Infections: Dead moss can become a breeding ground for mold and fungi, which can spread to your attic and harm your home’s structure and air quality.
• Warranty Issues: Adding shingles over a moss-covered roof can void the warranty on your new roof because of the potential damage it can cause.

Professional Advice

Always consult with a professional roofer before making any decisions. They can provide a thorough inspection and offer the best course of action. Professional roofers have the expertise to identify issues that might not be visible to the untrained eye.

Long-Term Cost Reduction

Removing the old, moss-covered shingles may seem like an added expense, but it can save you money in the long run. By addressing the root of the problem now, you avoid costly repairs and potential roof replacements in the future. Plus, you keep the option open to add a second layer of shingles during your next roof replacement, which is often more cost-effective.

Home Value Maintenance

Are you planning to sell your home soon? A properly replaced roof is more likely to appeal to potential buyers. A poorly replaced roof, especially one with underlying moss issues, can negatively affect your home value. Buyers and inspectors will notice if the job was done right, impacting your sale price and speed.

Risk Avoidance

By removing moss-covered shingles, you eliminate the risks mentioned earlier. You get a fresh start with your new roof, ensuring that it functions properly and lasts as long as possible. This proactive step can prevent leaks, structural damage, and other issues that could arise from ignoring the moss.

In conclusion, while it might be tempting to save time and money by installing new shingles over moss-covered ones, the potential problems far outweigh the benefits. For more information or to schedule a consultation, fill out our contact form or call us at (800) 914-4108.

Does Dawn dish soap kill moss on the roof?

Dawn dish soap can be used to kill moss on your roof, but it’s not the most effective or recommended method. While some homeowners use a mix of dish soap and water, this solution might not be strong enough to deal with extensive moss growth. Additionally, using dish soap can create a slippery surface, increasing the risk of falls.

For a more effective solution, consider using a moss-specific cleaner or a DIY mix of water and white vinegar or baking soda. These solutions are known to be more effective and safer for your shingles.

What is the best product to kill moss on a roof?

Several products are available to kill moss on a roof, each with its own advantages:

• Moss-Specific Cleaners: These commercial products are designed to kill moss without damaging your shingles. They are often the most effective and easiest to use.
• Homemade Solutions: A mix of equal parts water and white vinegar or a solution of 1 part baking soda to 1 part water can be effective. These are eco-friendly and safe for your shingles.
• Zinc-Based Products: Zinc strips or zinc sulfate solutions are excellent for both killing existing moss and preventing future growth. When rainwater washes over zinc strips installed near the ridge of your roof, it creates an environment that inhibits moss growth.
