Your roof is not just a functional element of your home; it's a protective shield against the elements. Over time, however, asphalt shingles can accumulate dirt, debris, and moss, compromising their appearance and durability. Fear not, for with proper techniques cleaning asphalt shingles made easy, you can restore them to their former glory and ensure the longevity of your roof. In this guide, we'll walk you through everything you need to know on how to clean roof shingles, from understanding the importance of maintenance to step-by-step cleaning methods and frequently asked questions.

The Significance of Clean Shingles

Why Clean Asphalt Shingles?

Cleaning your asphalt shingles or any types of roofs isn't just about maintaining a pleasing appearance; it's about safeguarding your investment. Over time, dirt, debris, shingles blown off the roof, and organic matter can accumulate on your shingles, leading to premature deterioration. Regularly cleaning your roof prevents these elements from causing long-term damage and ensures your shingles can perform optimally for years.

Benefits of Regular Roof Cleaning

Regular cleaning goes beyond aesthetics. It prevents moisture retention, which can lead to mold and moss growth, ultimately compromising your roof's structural integrity. Moreover, cleaning asphalt shingles helps remove algae from the roof and maintains energy efficiency by reflecting sunlight instead of absorbing it. This simple practice can even extend your roof's lifespan, saving you from costly repairs.

Understanding Asphalt Shingle Composition

What are Asphalt Shingles Made Of?

Asphalt shingles are like sturdy blankets for your roof, crafted from a mix of strong fiberglass or natural fibers covered with protective asphalt. These granules give shingles their color and protect against UV rays and impact. Understanding this composition is crucial as it determines how you clean and maintain your shingles.

How Composition Affects Cleaning

The mineral granules on asphalt shingles can wear down over time, affecting their ability to shield your roof from the sun and rain. This gradual erosion is natural but can be expedited by improper cleaning techniques, leading to premature aging of your shingles. Therefore, gentle cleaning methods are essential to preserve your roof's longevity.

Essential Tools and Materials

Gather Your Cleaning Arsenal

Before embarking on your shingle-cleaning journey, assemble the necessary tools and materials. You'll need a sturdy ladder, safety equipment, a garden hose, a soft-bristle brush, a bucket, and products for cleaning asphalt shingles. Avoid abrasive tools or harsh chemicals that can damage your shingles and the environment.

Quality Matters: Choosing the Right Tools

The best way to clean roof shingles is to invest first in high-quality tools that pay off in the long run. A sturdy ladder ensures your safety during cleaning, while a soft-bristle brush removes debris without scratching the shingles. Opt for eco-friendly products for cleaning asphalt shingles to protect both your roof and the environment.

Cleaning Methods

Pressure Washing: Yay or Nay?

Pressure washing may seem efficient but can cause more harm to the parts of an asphalt shingle. The forceful stream of water can dislodge granules, leading to premature shingle wear. Instead, use gentler methods, such as manual cleaning. We will teach you how to clean the roof without damaging shingles.

Step-by-Step Guide to Manual Cleaning

  1. Safety First: Wear appropriate safety gear, including non-slip shoes and eye protection.
  2. Clear Debris: Gently remove loose debris using a leaf blower or a soft-bristle broom.
  3. Prepare Solution: Mix your eco-friendly asphalt shingle cleaner as per the manufacturer's instructions.
  4. Wet Shingles: Thoroughly wet the shingles using a garden hose.
  5. Scrub Gently: Dip the soft-bristle brush in the cleaning solution and scrub the shingles in a circular motion.
  6. Rinse: Rinse off the shingle roof cleaner solution using your garden hose, ensuring no residue remains.

The Art of Gutter Cleaning

Cleaning your gutters is as important as cleaning the shingles. Clogged gutters can lead to water backups, damaging your roof and foundation. To ensure that your asphalt shingles stand out, clear out leaves, twigs, and debris to ensure proper water flow.

Tackling Stubborn Stains

Dealing with Mold and Mildew

In damp places, mold and mildew can easily grow, making your shingles look bad. But don't worry! You can fight this. Mix water and vinegar together in the same amount and spray it on the spots that are affected. Wait for 15 minutes, and then gently scrub and rinse. And hey, there's more – moss can be a pain, too, so remember to clean asphalt shingles on a roof moss. Your roof will thank you for your love and care!

Oil Stains Begone!

Oil stains can be challenging to remove, often caused by a malfunctioning chimney or HVAC system. Apply a small amount of baking soda on the stain, let it absorb the oil, and then sweep it away. Repeat as necessary. 

The question we often get about removing stains is, "Will bleach damage asphalt shingles?" The answer: No, it won't. Bleach works well to clean asphalt. Just remember to rinse the mixture really well to make sure it doesn't cause any lasting damage.

Preventive Measures

Installing Zinc Strips: A Wise Choice

Zinc strips, placed near the roof's peak, can prevent moss and algae growth. When rainwater runs over these strips, it carries tiny zinc particles that inhibit the growth of these unwanted organisms.

Trimming Trees: Keeping Shingles Clean

Overhanging branches can deposit leaves and debris on your roof, accelerating its wear and tear. Regularly trim trees near your roof to minimize this debris buildup.


Q: How often should I clean my asphalt shingles?

A: Ideally, you should clean your asphalt shingles at least once a year to prevent debris accumulation and maintain their appearance.

Q: Can I use a pressure washer on my shingles?

A: It's best to avoid pressure washing as it can dislodge granules. Opt for gentler manual cleaning methods to protect your shingles.

Q: Are there any eco-friendly cleaning solutions I can use?

A: Yes, you can create an effective cleaning solution using water, vinegar, and a small amount of mild detergent.

Q: What should I do about lichen growth on my shingles?

A: Lichen growth indicates excessive moisture. While cleaning can remove the visible growth, addressing the underlying moisture issue is crucial.

Q: Can I walk on my asphalt shingles during cleaning?

A: It's recommended to avoid walking on your shingles whenever possible to prevent accidental damage. Use a sturdy ladder instead.
