Our Proprietary Cleaning Process & Solution

The Process

Most providers of cedar roof cleaning services use a process that requires walking on the roof and use of a power washer. This is an outdated process that continues to be widely practiced. Walking on a wood roof and cleaning it with a pressure washer is both potentially harmful to the roof and quite dangerous.

Sullivan is the first roof cleaning service to develop a wood roof cleaning process that requires neither walking on the roof nor any form of pressure to clean it.

Many homeowners rightly express concern about the cleaning solutions that are used on their roofs. They wonder whether these solutions will harm their children, pets, landscaping, or other aspects of their home. While most cedar roof cleaning services utilize a caustic solution, ours is specially formulated to be gentle on your home and those who share it.

Our Proprietary Cleaning Solution

1.) Is nontoxic and non-caustic
2.) Formulated with a citrus-based component;
3.) Contains algaecide, mildewcide, and fungicide
4.) Utilizes a steam processed oil to rehydrate the shakes.

Our proven process and proprietary solution will fully clean and maintain your roof while posing no risk to your roof, your property, or your family. No further treatment is needed to preserve your cedar shake roof.

To maximize the lifespan of your cedar shake roof, have it professionally maintained every 7-10 years, depending on your local conditions. If it’s time to maintain your roof, call us. We don’t just offer cedar shake roof cleaning; it’s our specialty!

What can I say? Bruce and Keith provided an exceptional service, and they are really nice guys too. Found out at the last minute they were in Minneapolis, and they fit me in for a cedar shake roof cleaning the next evening after their regular job was done. Even cleaned up my gutters, small fence, and small deck at no charge. The place looks outstanding! Highly recommended.

I highly recommend this business. Due to the work performed we are going to get another 10-14 years out of our cedar shake roof. We were told by some roofing companies that the roof should be replaced in 2 years. I lucked out and found Sullivan Roof Cleaning while researching companies that perform this service, and was pleased to learn that the company does work outside of Iowa. If you need your cedar shakes cleaned, go with Sullivan Roof Cleaning.

Bruce did a great job cleaning the whole exterior of my house. The roof has new life! It looks practically brand new. All the mold and moss on the roof, on the gutters, under the eaves, completely gone. He exceeded all our expectations. When he tells you what he can do for your house, you can believe and trust him. Great guy, great service.

Cedar shakes are organic. Though a resilient material. Being organic they need to be maintained. Over time, like any organic material that are subjected to weather elements, they reach a stage of deterioration. Like UV exposure, moisture and seasonal changes. Which results in moss, mold, mildew, lichen and brown rot fungi. These infestations need to be removed to further preserve the integrity of the cedar shake.
The proper way to clean a cedar shake roof is from a ladder. By spraying a special formulated solution onto the shakes and then rinsed with a garden hose pressure. Best done by a professional cedar shake roof cleaner. Not DIY recommended.
No. Pressure washer will require walking on the shakes, which will harm them, and even at its lowest setting will also damage the shakes.
On average, cedar shakes should be cleaned every 10 ten years. Subjective to the grade of the shakes and the amount of surrounding tree cover.
Avoiding walking on a cedar shake roof, other than for repairs.
Never seal a cedar shake roof. Cedar shakes need to breathe. They expand and contract in rain conditions. Seal will shorten the lifespan, to the point of premature replacement.
Staining has no real preserve value and can also harm the integrity of shakes, as stated, they need to be able to breathe. Also, if the shakes are not properly cleaned staining can seal the deteriorating infestation within the shakes.
Depending on the grade of the shakes and installation, and if maintained properly, 40 to 60 years.
