What is the Average Cost of Cedar Shakes Roof Cleaning?

Here at Sullivan Cedar Shakes Roof Cleaning we are often asked what our “average cost” is for a roof cleaning job. The simple fact is that there really is no average. Even so, I’d like to address this question, as you may find it helpful to know how we charge for roof cleaning.

The cost of the average roof replacement depends on various factors.

Often there will be infestations that come from the surrounding environment and tree cover.  Your roof may be covered in moss, algae, lichen, or brown rot but this can be cleaned. Please note that brown rot is the number one cause of roof deterioration.

A damp roof that is surrounded by trees and other organic matter has the perfect climate for moss and fungus to grow, not only do the growths look unaesthetic, if you do not look after and maintain your cedar shakes correctly then they will not last the average 40 to 60 years!  If not then the life span is severely reduced and the roof will need fixing and replacing much earlier than otherwise necessary.  It is advisable to get a professional such as Sullivan Cedar Shake Roof Cleaning, to take care of your cedar shake cleaning needs, this ensures the highest quality work, no damage to your existing shakes, and a roof that looks as good as new.

Cedar Shake Roofs are expensive to install and often have a higher insurance cost than another roof of a similar size but even with those two points in mind Cedar Shake Roofs have many benefits that outweigh the relatively few downsides, and these are boosted by cleaning.

Each Roof & its Unique Situation

The fact is, each roof has its own particular circumstances and requires a specific response from us as cedar roof cleaners. It’s not about size; it’s about which infestations have become imbedded in the shakes and other problems that arise with that situation. There are various kinds of infestations, situations, leaks or problems that we may need to tend to in a single visit. On one occasion, a roof that was 4,000 sq. ft. cost more than a neighbor’s, whose roof was 6,000 sq. ft.! It seems hardly fair…until you look down the list of infestations, cracks, and the labor that was required to make other repairs on the smaller roof vs. the larger one, which had a milder infestation. We will be happy to give you an estimate but you will need to click the button below and fill out the form.

A Broad Range of Pricing

As a general estimate for the average cost of Cedar Shakes Roof Cleaning, it is around $0.50-$1.00 per square foot is about the closest we can come to a set price for a cost. Even though this is still a very broad range, it may allow you to see the variance we end up working with in the field and it can give you some insight into why we don’t provide a more direct answer before being able to see your roof via satellite. Our price for our Soft-Wash average cost of Cedar Shakes Roof Cleaning process is around 5% of the replacement cost, and one cleaning will last between 8-10 years. After having looked at other types of roof cleaning, we’ve also found our pricing to be about a third of the cost of others who use much more invasive processes to clean your roof such as pressure washing. Give us a call and we’ll set something up or, if you are out of our area, we’ll help locate someone near you, who can give you a proper estimate.

Life Span of 40 - 60 Years

A Cedar Shake Roof will last a long time, depending on the grade of the cedar, but it does need to be looked after and cleaned about once every 10 years or so. If the roof is neglected then it will need replacing before which will incur a huge amount of unnecessary costs.


Cedar Shakes are a naturally renewable and sustainable resource that is also organic matter. They also last longer than other materials and can be composted once no longer in use. Ensuring they stay in optimal condition will help to reduce the impact on the environment.

Maintain Temperatures

A cedar shake roof that is not maintained will lose some of its natural ability to hold an abient temperature. They allow the home to breath, to stay cool in the summers, and help to keep them warmer in the winters. If the cedar shakes become damaged, degraded, or generally fall into disrepair then all of this is lost.

Family, Pet, & Garden Friendly

The formula is specially created and offers maximum efficiency for cleaning of cedar shake roofs whilst being harmless to those most important to you.

Prevents Damage

Keep the roof in the best condition possible by keeping your Cedar Shakes clean and free of organic material.

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.
