Roof cleaning, like other roofing projects, is a job for professionals, not homeowners. When you hire a professional roof cleaner, expect to spend between $350 and $1500 for a national average cost of $900.
How big is your roof? What material is you roof made of? These factors and others will decide your exact roof cleaning cost. Typical prices range from $0.30 to $0.50 per square foot.
How much does roof cleaning cost?
• National average cost: $900
• Typical price range: $350 – $1500
• Extreme low end: $200
• Extreme high end: $2,000
For a typical roof cleaning job, you’ll most likely pay somewhere in the range of $350 to $1500. But keep in mind, some cleaning methods take more time and work, so they cost more.
Depending on your roof’s needs, you might end up spending as much as $1,500. If your roof is small, simple, and doesn’t require in-depth cleaning, you can expect to save money and spend closer to the low end of $300.
Roof Cleaning Cost by Home Size
Roof size is the biggest indicator of what your roof cleaning budget will look like. The larger the roof, the longer it will take to clean, and the more you’ll owe a professional roof cleaner depending on his rates.
Don’t know the size of your roof? You can estimate it pretty closely based on your home’s square footage. The formula to figure out approximate roof size is:
• 1.5 x square footage of home = Square footage of roof
Once you have a ballpark estimate of your roof’s size, you can calculate the total cost of roof cleaning using the typical range of $0.30 to $0.50 per square foot or the average rate of $0.40 per square foot.
The table below shows the typical cost range of several common roof sizes.
APPROXIMATE ROOF SIZE
AVERAGE COST TO CLEAN ROOF (based on per-square-foot cost range)
1,000 square feet to 1,500 square feet.
$300 – $750
1,500 square feet to 2,250 square feet
$450 – $1125
2,000 square feet to 3,000 square feet
$600 – $1,500
2,500 square feet to 3,750 square feet
$750 – $1,875
3,000 square feet to 4,500 square feet
$900 – $2,250
Other Cost Factors
What kind of roof do you have? What type of cleaning does the roof need? How many stories is your home, and how high is the roof off the ground?
If you want a clearer idea of what your budget should look like, you’ll need to consider all of this information, not just the size of the roof.
Gutter cleaning cost
Most professional roof cleaners also offer gutter cleaning. If your gutters are clogged with debris, you can pay your pros about $200 to $300 to clear out your gutters.
Cleaning your gutters is important and definitely worth the money. When your gutters stay clogged for a long time, rainwater will overflow, potentially damaging your landscaping or your home’s foundation.
Something else to consider: Gutter guards or leaf guards. Here’s why: Your gutters won’t get clogged as quickly if you install gutter guards to keep leaves out.
Roof repair cost
What happens if your roof cleaners find damage on the roof? You could spend anywhere from about $348 to $1,186 on roof repairs. Your exact cost for roof repair will depend on the roofing material and the type of damage.
A damaged roof vent is usually the easiest and least expensive issue to fix, while a sagging roof is a much more complicated repair that could cost thousands of dollars.
Roof replacement cost
As a general rule of thumb, you should have your whole roof replaced every 15 to 20 years. If you’ve waited longer than that, your roof’s problems might go well beyond a cleaning, and you might need a full roof replacement.
A roof replacement is a significant investment that usually costs between $5,706 and $11,185.
There’s no way to know exactly how much you’ll spend on a new roof without considering site specifics like the roof’s material, size, and pitch (whether it’s steeper or flatter than average).
Cost of Roof Cleaning by Location
While the chemicals and equipment needed to clean a roof will cost about the same no matter where you live, labor costs of different roof cleaning companies can vary by a lot.
What this means: The total amount you pay for roof cleaning could be different from our cost estimates, which are based on national averages.
In general, you can expect lower labor costs if you live in a small town with a low cost of living. On the other hand, homeowners in metropolitan areas shouldn’t be surprised if they end up paying more than we estimated.
FAQ about Roof Cleaning
1. Can you power wash a roof?
Most professional roofers don’t recommend power washing roofs because the intense pressure can damage or loosen shingles and tiles.
2. Can you clean your own roof?
No. Most importantly, it isn’t safe for you to get up on the roof. Another reason you should always hire professional roof cleaners is that they have access to better equipment and cleaning products than the DIY kits you can buy at the hardware store.
3. How often should you clean your roof?
Roof cleaning at least once every 5 years can make your roof last longer. Your roof might need more frequent cleaning if you live somewhere with a lot of wet weather or another climate that exposes your roof to dirt, moss, or salt.
4. Do you need to clean solar panels on your roof?
It’s true that dirty solar panels are less efficient than clean ones, but you usually won’t have to worry about cleaning them because rain will wash off dirt and debris for you.
If you live in a very dry climate where it doesn’t rain often, you may need to clean your solar panels occasionally.
