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 clean that organic growth without using the same pressure that would be used on concrete. The soft wash solution 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 cleaned 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 streaks make shingles look older and dirtier than they really are. These stains usually show a visible difference the same day.
Algae
Our soft wash removes the algae staining behind most of the dark streaks you see on asphalt shingles.
Moss
Moss is gently cleaned and loosened instead of being aggressively scraped off the roof. You’ll see an improvement right away, and the remaining growth dries out and releases over time.
Lichen
Lichen grips shingles tightly, so it’s the slowest to clear. After cleaning, it fades and releases gradually, often over several weeks to a few months depending on severity.
What Your Roof Looks Like After Cleaning
You’ll see a difference the same day, and the roof keeps improving over the following weeks.
- Dark streaks lighten right away. Some disappear completely, and others fade to a light brown that keeps clearing with time.
- Moss changes from green to brown or white as the cleaning solution goes to work.
- Lichen turns from black or gray to white or light brown.
- Moss and lichen release gradually with rain and weather, often over 1 to 3 months or more.
That color change is a good sign. The growth has loosened and is drying out. From there, rain, wind, and normal weathering lift it off the shingles a little at a time. Light growth often clears within a few weeks, while heavy, long-established moss or lichen can take a few months. I’ll explain that timeline before the work begins so you know what to expect.

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 cleaning.
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. Book once or as often as you like. I will not pressure you into a recurring plan.
Care Around Your Home
Clean the Roof. Protect What’s Below It.
Roof cleaning 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 cleaning begins, I review the roof, access points and the areas below it so I know where extra care may be needed.
Water the Landscaping
Landscaping around the work area is watered during the cleaning process, and the runoff is monitored.
Apply the Roof Cleaning Solution
The cleaning solution is applied as a soft wash, with no high pressure and no scraping.
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 cleaning 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 cleaning. 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 roof cleaning.
Why should I hire you?
I’m local, and this is my own business. I’ve invested in training and professional equipment so I can do the job right, and my name is on the line with every job. I’m the one who quotes it, does the work, and the one you call if anything comes up. No middlemen, no rotating techs. I’m also insured. On a roof, that means I look over the access and the landscaping below before I start.
How do I get ready for a roof cleaning?
Turn the outdoor water on, unlock gates and close all windows and exterior doors. Move vehicles, patio furniture, grills and smaller potted plants away from the house and out of the drip line.
I recommend watering the plants near the house the night before and again the evening after the cleaning. Water dilutes runoff, and if a plant looks stressed, watering it well helps flush the solution away. Let me know ahead of time about newly planted or sensitive landscaping. Keep pets inside and pick up pet waste. You don’t need to be home. The full checklist is on the Prepare for Your Service page.
Is roof cleaning safe for my shingles?
Roof cleaning is a soft wash. The cleaning solution does the work, so there’s no high pressure and no scraping on your shingles. Moss and lichen are cleaned, not scraped off, because pulling attached growth can be hard on the shingle surface. I avoid unnecessary roof walking and use application points that make sense for the roof’s layout, pitch and safe access.
What’s included in a roof cleaning, and what isn’t?
A roof cleaning is a soft wash that cleans black streaks, algae, moss and lichen. I water your landscaping during the cleaning and monitor the runoff.
Some staining or wear may remain. Runoff can partly clean nearby siding, concrete or other surfaces, and those areas aren’t included unless we agree on them in your quote. It isn’t a roof inspection or repair, but I’ll note any visible concerns. A roof cleaning pairs well with a house wash, because roof runoff can leave streaks or uneven patches on the siding below. Adding a house wash leaves the whole exterior evenly clean, with bundle pricing.
What affects the price of a roof cleaning?
Roof size and the number of sections, pitch and height, safe access, the amount and type of growth, and the overall complexity of the property all affect the price. You’ll get one simple price for the job before any work begins, and you can get it online with the instant quote. Starting prices are on my Pricing page.
What results should I expect, and how long does it take?
You’ll get reminders before the visit and a heads-up when I’m on my way. Black streaks typically clean up the same day. Moss and lichen turn white or brown, then release gradually with the weather over about 1 to 3 months or more. If it’s white or brown, it’s coming down.
Most roof cleanings take about 2 to 4 hours on site, depending on the roof. That’s an estimate, and it varies by home.
How do you protect my plants and landscaping?
I look over the landscaping around the home before cleaning and water it during the cleaning process, and I monitor the runoff. Roof cleaning uses a stronger solution than a house wash, so runoff can stress plants if it isn’t diluted. That’s why I also recommend watering nearby plants the night before and the evening after the service.
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.
