How To Get Rid of Roof Moss

Moss might seem harmless, but it can cause serious damage to your roof over time. At Berg Home Improvements, we believe in empowering homeowners with the knowledge needed to maintain their homes efficiently. This blog will explain the steps to remove roof moss and prevent it from coming back, ensuring your roof remains in top condition.

Why Moss is a Problem

Moss crowds the shingles, causing decay and leaks, and can eventually destroy a roof to the point of needing replacement. Wooden shingles are particularly vulnerable as they are porous and promote rotting faster than other shingle types. North-facing roofs typically receive the least sunlight and are more prone to moss, especially in cool and damp climates.

Prevention: The First Line of Defense

Preventing moss growth is always easier than dealing with an existing infestation. Here are some tips:

1. Trim Overhanging Trees: Cutting back branches that cast shade on your roof helps reduce the moisture levels that moss needs to thrive.
2. Regular Roof Cleaning: Sweep off leaves, branches, and other debris regularly to prevent moisture accumulation.
3. Install Zinc or Copper Strips: These metals inhibit moss growth. When rainwater washes over the strips, it carries moss-killing particles down the roof.

Effective Moss Removal Techniques

If moss has already taken hold, it’s crucial to remove it quickly to avoid further damage. Below are the best practices for moss removal:

Chemical Treatment

The most effective method involves a two-step process: applying a chemical treatment and then physically removing the dead moss.

• Dry Powder Moss Killers: Sprinkle the powder in multiple lines parallel to the house’s ridge, spacing the lines between 2 and 4 feet apart. This method works best in dry conditions.
• Liquid Moss Killers: These come in containers that attach to garden hoses, blending with water as it flows. This method ensures even distribution and is convenient to apply.

Physical Removal

Once the moss is dead, you can safely remove it without damaging your shingles:

• Scraping: Use a long-handled brush or scraper to gently remove the dead moss. Be careful not to damage the shingles underneath.
• Pressure Washing: For stubborn moss, a pressure washer can be effective, but use it on a low setting to avoid dislodging shingles.

Homemade Solutions

If you prefer a DIY approach, consider using a bleach and water solution or a vinegar and water solution. Apply the mixture to the moss, let it sit for 15-20 minutes, and then scrub it off.

Potential Problems and How to Solve Them

Water Damage

When removing moss, ensure the runoff water doesn’t damage your home’s exterior. Direct excess water away from walls and foundations.

Roof Damage

Improper scraping or pressure washing can harm your shingles. Always follow manufacturer guidelines and consider hiring professionals if you’re unsure.

Regrowth

Even after removal, moss can return. Implement the prevention tips mentioned earlier and schedule regular roof inspections to keep your roof moss-free.
