Shingle Cleaning 101: Simple Solutions To Clean Your Asphalt Shingles

Maintaining your home can be challenging due to the different tasks needed to keep your investment clean and functional. From mowing the lawn and cleaning the windows to repairing a leaking faucet, these obvious tasks will uphold your home's function, appeal, and total value. Unfortunately, you may not realize how a dirty roof can affect your home. Not only will a dirty roof affect your home's curb appeal, but heavy residue and mold growth can increase your risk of leaks and severe water damage. With these solutions for cleaning your roof, your asphalt shingles will look and remain durable for up to an estimated 30 years.

Standard Dirt and Dust

You most wash off your home's exterior siding and outdoor surfaces with a garden hose or pressure washer periodically. This is a sufficient way to remove dirt, dust, grass, straw, and other debris from siding, concrete, and wood surfaces of your home. This same maintenance should be conducted on your roof, since debris can quickly build up on your shingles.

To get started, consider creating a cleaning solution using natural ingredients that will not run off your roof and harm your landscaping. In an outdoor sprayer, add the following:

  • 4 gallons of warm water
  • 2 cups of baking soda
  • 2 to 3 drops of liquid dish soap

Shake the container to mix the ingredients together. Then, spray a generous amount of the cleaning solution onto your roof. Allow it to sit for a few minutes before rinsing the residue off using your garden hose or pressure washer.

To perform a general cleaning of your shingle roof, combine the following in an outdoor pump sprayer:

Mold or Algae Growth

Although most common in warm, moist climates, mold and algae growth may also appear on your roof. Mold will look similar to dark brown or black spots while algae looks more like black streaks spreading across the entire roof. If left in place, mold and algae can cause your asphalt shingles to rot and decay, leading to leaks and expensive water damage inside your home.

To remove while cleaning your roof, combine 2 gallons of warm water with 2 gallons of vinegar in your sprayer. Douse the solution across your shingles, allowing the acidic, antibacterial properties of the vinegar to eat through and kill mold and algae growth. Rinse your roof with your garden hose or pressure washer.

Asphalt shingles are incredibly durable, but they will require periodic cleaning to keep them clean and in good condition.  With a bit of effort, water, baking soda, and vinegar, you can remove dirt, dust, and harmful mold or algae growth from your shingles.
