Preparation for Cleaning

Before beginning the cleaning process for cedar shake shingles, it is essential to prepare adequately to ensure effective and safe cleaning. Start by assessing the condition of the shingles, checking for any damage or areas requiring repair.

  • Clear the area around the house to allow easy access to the shingles.
  • Protect any landscaping or surfaces below the shingles with tarps or plastic sheeting to catch debris and cleaning solution runoff.
  • Gather the necessary tools and materials, which may include:
  • A soft-bristle brush or broom
  • A pressure washer (with caution)
  • Cleaning solution (commercial or homemade)
  • Safety gear (goggles, gloves, and a mask)

Choosing the Right Cleaning Solution

Selecting the appropriate cleaning solution is crucial for maintaining the integrity of cedar shake shingles. There are several options available:

  • Commercial cleaners: These are specifically formulated for wood and can effectively remove mildew, mold, and dirt.
  • Homemade solutions: A common recipe involves mixing:
  • 1 cup of bleach (for mold and mildew)
  • 1 cup of dish soap
  • 1 gallon of water

Ensure the solution is safe for use on wood surfaces and does not contain harsh chemicals that could damage the shingles.

Cleaning Techniques

The cleaning process can vary depending on the degree of dirt and mildew present. Here are some effective techniques:

  • Gentle Scrubbing: Use a soft-bristle brush or broom to remove loose dirt and debris. Begin from the top of the shingles and work your way down to prevent water from getting trapped under the shingles.
  • Pressure Washing: If using a pressure washer, set it to a low setting to avoid damaging the wood. Maintain a distance of at least 3 feet from the shingles, and use a sweeping motion to rinse the area.
  • Applying the Cleaning Solution: Apply the chosen cleaning solution evenly across the shingles, allowing it to sit for 15-20 minutes to break down dirt and stains. Avoid letting it dry completely on the shingles.

Post-Cleaning Care

After cleaning the shingles, it’s important to ensure they are properly cared for to maintain their longevity.

  • Rinse thoroughly with water to remove any remaining cleaning solution.
  • Inspect the shingles for any damage that may need repair.
  • Consider applying a wood preservative or sealant designed for cedar shingles to protect against weathering and UV damage.

Cleaning Process

Follow these steps to clean cedar shake shingles effectively:

  1. Wet the shingles: Using a garden hose, spray water over the shingles to moisten them. This helps prevent the cleaning solution from being absorbed too quickly.

  1. Scrub gently: Start at the top and work your way down. Use light pressure to avoid damaging the wood. Focus on areas with heavy moss, mold, or dirt buildup.
  1. Let it sit: Allow the solution to sit for about 10-15 minutes. This will help lift stains and grime.
  1. Rinse thoroughly: Use the garden hose to rinse the shingles from the top down, ensuring all cleaning solution is removed. Avoid using a pressure washer, as it can strip the wood and create damage.

Post-Cleaning Care

After cleaning, consider the following maintenance tips:

  • Inspect for damage: Check for any shingles that may require replacement or repair.
  • Seal or treat: Depending on the condition of the wood, applying a wood preservative or water repellent can help prolong the life of the shingles.

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
