Roof Cleaning
in Oakland County, MI
Kill the Algae and Moss
on Your Oakland County Roof
Cold, snowy winters and humid summers are hard on a roof. The freeze-thaw cycles and long stretches of wet, snowy weather keep shingles damp, and that moisture feeds algae and moss, especially on north-facing slopes that sit in the shade and never fully dry out. Those dark streaks and green patches you can see from the driveway are living organic growth, and they keep spreading until something kills them.
We clean roofs the safe way, with a soft-wash method that kills the algae and moss without ever pressure washing your shingles. The solution does the work while the roof surface stays intact, so you get a clean roof without trading one problem for another. At Crystal Clear Window Care, we’ve handled roofs across the county for years.
If your roof is streaked, shaded, or overdue, call us at (248) 736-9537 and we’ll take a look.
The Roof Types We Clean in Oakland County
We adjust the soft-wash approach to the material your roof is made of, because what protects one surface can be wrong for another.
Asphalt Shingle
The most common roof material on single-family homes in the area, and the one most often streaked by algae. We soft wash it only, with no pressure washing on the shingles. The solution is applied and left to work so the granules and the shingle surface aren’t damaged.
Metal
We apply the soft-wash solution, then rinse the surface down. The whole job is handled without pressure that could affect the coatings or fasteners.
Cedar Shake
Shake is more porous than shingle, so it takes a higher solution concentration and a longer dwell to fully kill the growth. Soft wash only here as well; the method protects the wood rather than blasting it.
Clay Tile
The soft-wash chemistry lifts organic growth without any high-pressure contact on the tile. Where a pitch is fragile, we work from ladders or with our rooftop safety gear instead of walking a surface that isn’t safe to stand on.
Why Oakland County Homeowners Choose Us for Roof Cleaning
Roof work rewards doing it right, and a few things set our crews apart on this service in particular.
Insured to Work at Height, Including on Your Roof
We carry the coverage it takes to do this work safely, including the extra insurance that lets our crews go up on roofs and above 25 feet. Plenty of window cleaning companies assume they’re covered for that and aren’t. Here in Oakland County, that means the job gets done properly and you’re protected the whole time.
A Soft-Wash Method That Kills Growth Without Damaging Your Shingles
High pressure strips the granules off shingles and shortens a roof’s life. Our soft-wash approach skips the pressure entirely, killing the algae and moss with the solution alone so the growth clears while the surface underneath is left exactly as it should be. It’s the difference between a roof that’s clean and a roof that’s been worn down to get there.
Your Plants and Landscaping Are Protected
A roof job sends runoff straight down onto the beds and landscaping around the house. We rinse and dilute those surfaces so the plants below stay healthy while the roof above them gets clean.
A Local Company That Stands Behind the Work
We’re locally owned, and we’ve cleaned roofs across Oakland County for over a decade, with reviews around the county to back it up. When you hire us, you’re hiring a company that lives here and has to answer for its work here.
How Our Roof Cleaning Process Works
From your first call to a finished, invoiced job, here’s exactly what happens.
1
The Free Estimate
Call, text, or submit the form on our website, and the office gets back to you fast during business hours. A simpler roof can often be quoted from square footage we measure on Google Earth or Maps; a larger or more complex roof gets an in-person look. Either way the estimate is free and covers the scope, the method, and what to expect, usually within twenty-four hours.
2
Scheduling and the Heads-Up
Once you approve the estimate and a deposit reserves your date, the job is booked. You’ll get a confirmation, reminders as the day approaches, and an “on our way” text on service day so you’re never left guessing.
3
Hazard Check and Plant Protection
When the crew arrives, they walk the property for hazards like power lines, then pre-rinse the plants, landscaping, and surfaces near the roof and downspouts. Patio items and anything else in the runoff path get moved or covered before a drop of solution goes up. If your gutters need attention too, our gutter cleaning is an easy add-on while we’re already up there.
4
The Soft-Wash Application
The soft-wash solution is sodium hypochlorite, the same type of chlorine used to keep a pool safe, and it goes on through our soft-wash system at a concentration matched to your roof. Porous cedar shake gets a higher concentration and a longer dwell; metal gets rinsed. The solution is left to work rather than brushed or pressure-washed, so the shingles aren’t damaged. Most roofs are cleaned without anyone walking on them, and our crew is insured to go up with harnesses and ridge hooks when a flat, very large, or otherwise hard-to-reach roof calls for it.
5
Rinse-Down and How the Roof Clears
We rinse and dilute the surrounding surfaces one more time to keep everything below the roofline protected. Most of the algae and moss will visibly die right away, and the rest keeps clearing over the following weeks as rain and weather carry it off. A heavy case may need a second application. That gradual clearing is exactly how the method is designed to work, and it sets in without any harsh pressure on the roof.

Walkthrough and Invoice
The crew confirms the finished work with you and cleans up the site before leaving. Invoicing follows once you’re satisfied, never before.
Roof Cleaning Pricing in Oakland County
Most roof cleaning jobs in the area fall inside a documented range, and the final figure depends on the roof itself, its size, its material, and how complex the roofline is.
- Roughly $500 to $2,250. Priced by square footage, with the lower end for smaller, simpler roofs and the upper end for large or complex rooflines. Cedar shake sits higher because it takes a stronger solution concentration and a longer dwell. Most jobs run about two to four hours.
You can also bring the cost down by combining services:
- Multi-service bundle: 5% off two services, 10% off three, and 15% off four, which applies when roof cleaning is booked alongside other work like house washing. Just ask about it when you get your estimate.
- Recurring discount: 5% quarterly or 10% monthly is available where a recurring cadence actually makes sense. Most roofs don’t need cleaning that often, so we’ll only suggest it if it fits your situation.
Our Roof Cleaning Guarantee
We guarantee your roof will come clean. Because the solution keeps working over 30 to 60 days, we ask you to give it that time, and if it still needs it after that, we’ll come back and do another application. The results build for weeks after we pack up, which is exactly what you want from a method this gentle on the roof.
And across everything we do: if you’re not happy with the result, we’ll come back out and make it right. That’s our 100% satisfaction guarantee.
Roof Cleaning FAQs
Will my roof look clean the day you finish?
Not entirely, and that’s exactly how the method is designed to work. We soft wash your roof and let the solution do the work. Most of the algae and moss will visibly die off right away, but the rest keeps clearing over the next 30 to 60 days as the weather washes it away. If your roof still needs it after that window, we’ll come back and apply another treatment. A heavy case sometimes needs a second application, which is expected rather than a sign anything went wrong.
Do you walk on my roof or pressure wash it?
Most roofs are cleaned without anyone walking on them, and we never pressure wash the shingles. The soft-wash solution is applied and left to work, so the roof surface isn’t damaged. When a flat, very large, or otherwise inaccessible roof requires access, our crew is insured to go up and uses harnesses and ridge hooks for safe footing.
Do I need to be home for my roof cleaning?
No, not for the roof cleaning itself, since it’s exterior work. We just need access to a working water spigot and any gate codes. We’ll confirm those details when we schedule so everything’s ready on service day.
