Learn About Roof Cleaning
That time of the year is here! Yes, we’re talking about spring cleaning. From top to bottom in every room of your home, you’re cleaning, scrubbing, and discarding things no longer needed. But what about the exterior of your home? Have you scheduled a power washing for your siding and a professional roof cleaning?
Is roof cleaning really necessary?
It may not be ‘the law’, but if you want to keep your home healthy, then yes, roof cleaning should be considered necessary. Your roof is currently durable and protective, but over time, you’ll start to see dark streaks forming caused by algae growth. That algae will be accompanied by assorted debris, dirt, dust, and leaves sticking to it, taking away from the aesthetics of your home.
So, consider these three primary reasons why you should make roof cleaning part of your spring-cleaning process here in Cincinnati:
1. Keep Your Home Looking Good
Whether you have an asphalt, metal, or tile roof, you want the beauty of the colors and style to shine! And if your home is in an HOA neighborhood, roof cleaning is most likely required. Regardless of where you’re located, think curb appeal! And if you’re planning on selling your home, a roof cleaning could be the one thing that makes your home stand out above the others.
2. Lifespan Is Doubled
Getting a new roof installed is a substantial investment and you want to take care of that investment so that you can get the most from it. Annual roof cleaning will get the algae, debris, dirt, dust, limbs, and other things off will extend your roof’s lifespan. You can do this yourself or hire a professional who will have the proper equipment, supplies, and methods so that your investment isn’t damaged.
3. Energy Efficiency
A new roof is energy-efficient after it is installed, but it won’t stay that way if it gets coated in algae and other debris. Regular roof cleaning keeps those things that will decrease energy efficiency, saving you money on utilities and keeping your home comfortable inside.
What is there to know about roof cleaning?
You have a garden hose with a nozzle attached, what more is there to know when it comes to roof cleaning? Well, first of all, that garden hose and nozzle probably aren’t going to do a thorough roof cleaning. Second, unlike a professional contractor, you won’t know the amount of pressure to use if you do have a pressure washer and you won’t know what chemical products to use.
There are two methods of roof cleaning, each having risks. Those methods are:
- Pressure Washing: This is done with a pressure washer that sprays water on the roof and is great for removing algae, dirt, mold, and more.
- Chemical Cleaning: This is often referred to as a soft washing process. This method uses chemicals that remove those harmful elements from the roof.
What are the risks of roof cleaning?
The risks associated with the two methods of roof cleaning are:
- Pressure Washing: When done at the wrong pressure, you can do more damage than roof cleaning.
- Chemical Cleaning: The downside to this is the runoff can damage or harm any landscaping around the house if protective measures aren’t taken to protect those areas.

What type of roof cleaning is best?
Depending on the roofing material, a professional roof cleaning will start with a brush cleaning using a stiff broom. That will remove the loose matter on the roof, and then the contractor may rinse with clear water before beginning the final cleaning.
Many roof cleaning contractors use Sodium Hypochlorite, basic household bleach, for asphalt shingle roof cleaning. There are also products available over the counter that you can purchase that state they are specific for cleaning certain matters off a roof, like algae. If you’re doing your own roof cleaning, make sure to read the label and warnings about the product.
What is the cost of roof cleaning and is it worthwhile?
The cost of a professional roof cleaning will depend on the shape and size of the roof as well as the roofing material. They can start around $300 and go upward, you may find a less expensive roof cleaning service, but make sure they are experienced, licensed, and insured.
In Closing
