Asphalt Roof Cleaning

Remove stains, moss, organic matter, and Algae to bring your Asphalt roof back to life!

"Not only will cleaning restore the appearance of your asphalt roof, but it will also help add years to the lifespan."

How the Asphalt Cleaning Process Works

So your composite/asphalt roof has those black roof stains. The first thought is “Do I need a new roof?”

In reality, all you need is an asphalt roof cleaning to extend the years of life left in your roof.

Those black roof stains are just common algae. They are the result of the surrounding tree cover releasing spores that fester on your roof. Over time, which can be anywhere from 7 to 10 years, they appear. As you can see by the picture example below, all that is needed is a good roof cleaning to resolve the problem.

Not only will a cleaning restore the appearance of your asphalt roof but it will also help add years to the lifespan.

Benefits of our Asphalt Cleaning Process

Increase the Life Span of Your Roof

Keeping your Asphalt Roof Clean will allow you to extend the life and keep it in great condition for many more years to come.


Our Asphalt Roof Cleaning Forumula is biodegradable and environmentally friendly but will also make sure your roof is clean and looks good as new. Some people will advise to replace the roof, but replacing a roof is often unnecessary especially when a good clean of your Asphalt roof will do!

Water Pressure of a Garden Hose

A pressure washer will do more damage to your roof, it is especially important that you do not use one or the contractor use one. Nothing more than a simple garden hose and the Sullivan Asphalt Roof Cleaning formula is needed in order to get your roof back.

Family, Pet, & Garden Friendly

The Sullivan Asphalt Roof Cleaning forumla is specially created to be friendly to you, your family, your pets, and your garden

What we do?

We clean, treat and restore Asphalt roofs throughout the Des Moines, Iowa area and surrounding region. We remove all algae, moss, mold, mildew, lichen, and fungus from the roof. Along with our non-pressure cleaning process, we use a citrus-based solution that is non-toxic and non-caustic, this is safe for you, your family, your pets, and your garden. The use of this formula will extend the lifespan of your Asphalt roof and also restore the original color of the roof.

Extending the Life of Your Roof

An Asphalt roof will often become covered in various organic matter and materials depending on the local surroundings and weather conditions. This is important to remove in order to keep the roof in the best health possible.

The Sullivan Asphalt Roof Cleaning service can help extend the lifespan of your roof for a substantially reduced cost compared to that of an unnecessary renewal. Along with the friendly nature of our cleaning formula, we also make sure not to walk or climb on your roof as this can cause unnecessary damage which will extenuate any issues and cause them to accelerate.

We provide honest, reliable, and professional communication to you.  Please check out our testimonials to see what our customers say about us.

Use Asphalt Cleaning Experts

Even if your Asphalt roof has dark, ugly streaks or an abundance of moss and algae causing it to deteriorate and making it weak over time; you can get it cleaned by Asphalt Roof Cleaning professionals. We use a low-pressure roof cleaning system that ensures the roof is not subjected to unnecessary high-pressure that can cause damage and penetrate into the roof causing persistent damp.  The Sullivan environmentally-friendly Asphalt Roof Cleaning formula removes all damaging organic material without damaging your roof or surrounding area whilst saving you the drama of having to replace your entire roof.

The Sullivan Asphalt Roof Cleaning formula is biodegradable to ensure it is safe for you, your family, your pets, and your garden. Many roof cleaners will actually cause more damage than good as they do not follow best practices and techniques. 

When hiring an Asphalt Roof cleaning professional make sure to hire a knowledgeable, certified, and experienced professional who will perform a  proper inspection, and use the correct cleaning processes; Sullivan Roof Cleaning covers all of these points with their decades of experience.

Exterior Cleaning Roof & Siding, Johnson, Iowa

Amazing! I had the roof, siding and soffit cleaned on my 14 year old home. I can’t believe the difference it made! It looks new again! Sullivan was great to work with. There was absolutely no trace they had been there, other than the clean house and roof! I am very pleased. I will refer my friends and family to Sullivan Roof Cleaning!

Siding and Deck Cleaning, Johnson, Iowa

I found Bruce and Maria via their Your Tube video demonstrating their approach to cleaning the “green” stuff growing on the north and east sides of my home. I recommend watching it, it’s exactly who they are and what they do.

My house, deck and patio look brand new! I wish I had taken before pictures. The improvement is dramatic.

They arrived as scheduled, worked efficiently and with respect for my property. The work was completed for exactly the bid they provided when they visited my home to provide a free quote. I wish all contractors were so reliable and transparent. I am a very satisfied customer.

Cleaning Product Works-Des Moines

Bruce has done several roof cleanings for me and the results always exceed my expectations. He’s saved me thousands of dollars on my investment properties by making old roofs look brand new. He cleaned my gutters and siding in just a few minutes in what would have taken me hours with a power washer. With just a simple rinse, his cleaning solution removed dirt and grime that a pressure washer couldn’t remove. He’s got an amazing product.

Roof Cleaning-Pleasant Hill, Iowa

I was skeptical of this when my wife suggested it. I told her roofs were suppose to do this after time. I went to Menards to purchase a product and tried it in a small area ( no results) we went ahead and had it done and our roof looks like the day we had it installed. This is the best money we have spent to keep the house looking like the day we built it. GREAT JOB!!! I would recommend this to anyone.

You did an awesome job on my daughter’s log home, deck, railing, swing and chairs on the deck. They are totally impressed. My roof looks great, as well as, the stucco on front of my house. I appreciated your professionalism regarding communication and being where you said you would be at the time agreed upon.
