Cleaner Roof • Better Curb Appeal
Bring Back the Look of Your Roof.
Black streaks, algae, moss and lichen can make an otherwise good roof look worn out long before the shingles are actually due for replacement.
Roof cleaning is designed to treat that organic growth without using the same pressure that would be used on concrete. The treatment does the cleaning work while the shingles stay in place.
Some results happen quickly. Others take time. Black streaks often improve the same day, while moss and lichen may remain visible as the treated growth dries out and releases naturally.
Asphalt Shingle Roof Cleaning
What Can Roof Cleaning Help With?
Roof cleaning is intended for common organic growth on asphalt shingles. The type of growth affects how quickly you will see the final result.
Black Streaks
Dark roof streaks can make the shingles look older and dirtier than they really are. These areas often respond quickly to treatment.
Algae
Roof treatment targets the organic growth behind much of the dark staining commonly seen on asphalt shingles.
Moss
Moss is treated instead of being aggressively scraped from the roof. The treated growth is allowed to dry out and release over time.
Lichen
Lichen can take longer to release. Heavier areas may stay visible after treatment while the growth gradually breaks down.
Real Treatment • Real Expectations
What Will My Roof Look Like After Treatment?
Roof cleaning is different from washing a driveway. Some growth responds quickly, while other growth needs time to dry out and release from the shingles.
The Treatment Starts Working Right Away.
The final appearance depends on what is growing on the roof. I explain that timeline before the work begins so you know what to expect instead of promising that every roof looks completely finished the same day.

Your Roof Gets My Attention From Quote to Completion.
When you request roof cleaning from Timler Exterior Services, you work directly with me. I review the roof, answer your questions, schedule the work and complete the treatment.
Before I move forward, I look at the roof layout, pitch, access, condition and the areas around the home. If I do not think the roof is a good fit for my service, I’ll tell you rather than trying to force the job.
Roof cleaning can be a one-time service or something you schedule again when it makes sense. There is no contract or subscription requirement, and I will not pressure you into a recurring plan.
Care Around Your Home
Treat the Roof. Protect What’s Below It.
Roof treatment happens above landscaping, siding, windows, patios and other parts of your property. I pay attention to those areas throughout the job, not just the shingles.
Look Over the Property
Before treatment begins, I review the roof, access points and the areas below it so I know where extra care may be needed.
Water & Rinse Landscaping
Plants, grass and landscaping around the work area are watered and rinsed as needed before, during and after the roof treatment.
Apply the Roof Treatment
The cleaning treatment is applied at low pressure. The roof itself is generally left unrinsed so the treatment can continue working after I leave.
Property-Specific Pricing
What Affects Roof Cleaning Pricing?
Roofs can vary significantly in size, pitch, layout and access. Instead of publishing a broad price range that may not fit your property, I price the actual roof and the treatment it requires.
Roof cleaning pricing is based on the roof size, pitch, number of sections, access, amount and type of organic growth, and the overall complexity of safely completing the treatment. A simple roof section and a large, multi-level roof can require very different amounts of time, solution and property protection.

Roof Cleaning FAQs
Common Questions.
Roof cleaning works differently than pressure washing concrete. These are the questions homeowners most often have before scheduling a treatment.
Do you pressure wash asphalt shingles?
No. Asphalt shingles are cleaned with a low-pressure treatment. The cleaning solution is intended to do the work instead of using high pressure on the roof.
How quickly will black roof streaks disappear?
Black streaks and algae often show a noticeable improvement the same day. The exact result depends on the roof condition and the amount of growth present.
What happens to moss and lichen after treatment?
Moss and lichen are treated instead of being aggressively removed. The growth dries out, breaks down and gradually releases from the shingles. Heavier areas can take weeks or months to fully weather away.
Do you rinse the roof after treatment?
The asphalt-shingle treatment is generally left on the roof so it can keep working after the service. The shingles are not pressure-rinsed as part of the standard treatment.
How do you protect plants and landscaping?
I look over the landscaping around the home before treatment and water or rinse plants, grass and other areas as needed throughout the job. Property protection continues during the treatment, not just at the beginning.
Do you have to walk on my roof?
Not always. I avoid unnecessary roof walking and use application points that make sense for the roof layout, pitch and safe access available.
Can every roof be cleaned?
No. Roof material, condition, pitch, height and access all matter. I review those factors before accepting the project and will let you know if the property is not a good fit for my service.
Do I need to be home during the roof cleaning?
Usually not. As long as the property is accessible and any preparation instructions have been completed, most roof treatments can be performed while you are away.
