Should asphalt shingles be cleaned and can you power wash asphalt shingles? The answer to both questions is yes. Protecting your roof from potential damage to the shingles requires constant and high-quality maintenance. But how do you do it? Read on to find out useful tips to delay roof replacement and a complete guide to keeping your roof clean.
How to clean a asphalt shingle roof properly and safely? First, when cleaning the roof, you really need to take care of the safety of the roof and the surrounding area.
Do not use a pressure washer with too much pressure unless you have experience with it. High pressure can damage the protective granules on the shingles, which will lead to rapid wear and may cause leaks. Therefore, gentle cleaning with low-pressure and environmentally friendly products is recommended.

Basic tools for cleaning an asphalt shingle roof:
Now let’s discuss the environmental friendliness of this process. First of all, use environmentally friendly detergents that do not harm the environment when you clean and maintain your shingles. In addition, protect the surrounding vegetation from the cleaning solution, as some chemicals can harm flowers and lawns.
Step 1: Inspect the Roof for Damage or Debris
Periodically inspect the roof for damage, missing or broken shingles, loss of granules, debris buildup, and structural problems. Check gutters and sealants and also look for signs of damage inside the house.
Step 2: Protect the Plants and Foundation Areas
First, protect the plants from chemicals. Water the plants before cleaning and cover them with plastic wrap. Then create a barrier for the chemicals to run off. Use non-toxic cleaning agents. After cleaning the roof, rinse the plants and check their condition periodically.
Step 3: Clean Roof Shingles and Remove Loose Debris from Your Roof
In the third step, remove debris from the roof. Use a leaf blower or soft brush to remove leaves and branches. Do not use metal tools to avoid damaging the shingles.
Step 4: Prepare and Apply the Appropriate Cleaning Product
Select a suitable asphalt shingle cleaning solution (chemical or natural product). Prepare the cleaning solution according to the instructions and test it on a small area of the roof. If everything is fine, apply the cleaning solution evenly to the roof and leave it on for a while (also according to the instructions). Finally, rinse the roof thoroughly with water.
Step 5: Use Soft-Bristled Brushes to Tackle Moss, Lichen, and Algae
How to remove from asphalt shingles debris and other dirt? Use soft brushes to remove moss, lichen, and algae. Gently clean your roof shingles, avoiding excessive pressure. Ensure your own safety when working and rinse the roof with water after cleaning.
Step 6: Rinse the Roof with a Pressure Washer and Clean the Surrounding Plants
Rinse with clean water under low or high pressure to remove all residual products. When finished, remove the films from the plants and spray them with water to remove any residual chemicals.

Type of pollution | Cause | Cleaning methods |
Moss | Wet, shaded areas of the roof, particularly the northern slopes. Retains moisture, which can damage the shingles. | A solution of water and chlorine bleach in a ratio of 50:50. Apply for 15-20 minutes, then rinse off with low water pressure. |
Algae and black streaks | Humid climate, in particular high humidity. Black streaks are usually caused by the algae Gloeocapsa Magma. | A solution of water and bleach or a mixture of water and white vinegar for environmentally friendly cleaning. |
Lichens | Persistent adhesion to the roof surface, causing damage to the roof material. | Manual cleaning with a soft-bristled brush after applying the cleaning solution. Be careful not to damage the shingles. |
We’ve put together some basic tips for regular roof inspections:
Type of area | Recommended cleaning frequency | Reason |
Urban area (downtown Chicago) | Every 1-2 years | High level of air pollution due to traffic and buildings |
Suburban area (with a lot of trees) | Every 2 years | More leaves, moss, and lichens due to shade from trees |
Areas with high humidity | Annually | High humidity promotes moss and algae growth |
Industrial zones | Every 2-3 years | Air pollution and dust can lead to discoloration of the roof |
Coastal areas (Lake Michigan) | Annual | High winds and moisture levels increase debris and promote moss growth |
First, professional roof cleaning services ensure safety and expertise. Professionals use the proper equipment and techniques to safely and effectively clean your roof without risking damage to your shingles.
Second, asphalt shingle cleaners can identify potential problems early on. During the roof cleaning process, they may notice damaged or worn areas of the roof that you can repair in time to avoid serious costs in the future.
Third, cleaning protects your roof from the elements. In Chicago, with its hot summers and cold winters, organic dirt and debris can retain moisture, which accelerates shingle wear. Professional cleaning reduces these risks.
Last but not least, cleaning prevents relatively shortening the time of the roof’s service and improves the aesthetic view of the house. Cleaning eliminates moss, algae, and stains on the roof making the roof functional as well as beautifying the face of the home which is useful for increasing its value.
Let’s summarize, if you keep your Chicago roof cleaned regularly and make timely repairs to minor issues, those asphalt shingles won’t need replacing for more than 20 years. If not, the buildup of dirt, algae, and moss can lead to damage your shingles and structural problems. We recommend ordering professional roof cleaning from local roofing companies, as our specialists know all the ins and outs of this process and will be able to conduct a thorough diagnosis that will reveal hidden damage. This is beneficial both in the long run and for the quality of any roofing work.
For example, regular cleaning an asphalt roof can significantly extend the lifespan of your roof. When dirt, moss, or lichen accumulates on the roof, it creates a moist environment that promotes algae and moss growth and material deterioration.
After winter, snow, ice, and dirt can remain on the roof, causing damage to the tiles. During the cleaning process, experts help prevent algae and moisture penetration and improve the condition of the roof before the next season.
If you see stains, moss, or algae on your roof, or if you notice damaged wood shingles, it may be a sign that cleaning is needed. In addition, regular inspections can reveal problems that require professional intervention.
If you see stains, moss, or algae on your roof, or if you notice damaged shingles, it may be a sign that cleaning is needed. However, it’s best to have your roof cleaned regularly, rather than when it already shows significant signs of damage or contamination.
So, if you clean a roof regularly, it will have a much longer service life. This reduces the amount of dirt, moss, and other contaminants, which if allowed to build upon the surface, will cause a lot of harm to the material’s longevity. In addition, a clean roof better resists the effects of weather conditions.
