Cedar Roof Cleaning: A Guide To The Cleaning Process and Proper Maintenance

Three Step Process For A Cleaning Cedar Roof

From the past to present day many cleaners use what is called the 3 step process for cleaning a cedar roof.

  1. Cleaning
  2. Brightening
  3. Staining, Sealing & Weatherproof.
  • The cleaning solution which is commonly used is Sodium Percabonate.
  • The brightening solution which is commonly used is Oxalic Acid.
  • The staining, sealing & weatherproof can be any number of combinations.

Three Step Cedar Roof Cleaning Process

Sodium Percabonate doesn’t clean well and requires the use of pressure to completely clean the roof. Thus the use of a pressure washer which is to high (500 to 1000 psi) of pressure and will damage and erode your cedar shakes. Common sense indicates you would not want pressure of any form used on your wood roof. The downfall to the use of sodium percabonate is that it takes pressure to remove the solution.

Oxalic Acid as a brightener solution is a poisonous, crystalline acid used in many industrial purposes including rust removal and bleaching. It is both toxic and caustic. It also requires the use of high pressure to properly remove.

Staining, Sealing & Waterproofing. You can stain a cedar or wood roof to take on different hues or tones. Other than cosmetic staining has no true benefit. Sealing is the last thing you should do to a cedar or wood roof as they need to breathe or expand and contract with the weather conditions, thus the spacing between the shakes. Waterproofing has limited effectiveness and has a short shelf life.

Cedar Roof Maintenance

Simply speaking cedar shakes or wood roofs should stay in their natural form as when they were installed. Cedar does not decay in and of itself. Only moisture and different infestations will decay cedar. Cedar does weather and needs to be maintained to last there designed life span. The only maintenance a cedar roof needs is a good cleaning every 5 to 10 years which is subjective on tree cover, moisture and weather condition.

Cedar is a natural insulator against the environment; competitors can’t come close to the thermal efficiency of wood. In fact, cedar has twice the thermal resistivity (R-value) of asphalt, 5 times that of slate, 8 times that of concrete, and hundreds of times that of metal and aluminum.

Cedar roofs don’t decay, but they do weather. It has natural preservatives that resist moisture, decay and insect damage. Although in warm, humid climates and on heavily shaded roofs, algae, moss, mold, mildew, lichen and fungi’s will grow, because these organisms retain moisture the cedar will decay in time if not maintained.

When new the shakes and shingles display the natural honey and cinnamon tones, and will later mature to a seasoned and distinguished-looking silvery gray when properly maintained.

When Your Cedar Shakes Need To Be Cleaned

If the shakes or shingles display a brown/dark brown to black tones, these are signs of harmful organism infestations and they need to be cleaned. The same applies to moss, mildew, lichen and fungus.

Three Step Cedar Roof Cleaning Process

With a proper cedar roof maintenance program a cedar roof will last anywhere from 40 to 60 years which is also subjective to conditions and if maintained.

There is an alternative to the 3 step process for cleaning cedar shakes or wood roofs and for roof cleaning.

It is a 1 step process: Cleaning. In todays roof cleaning industry the process or equipment used to clean a roof is what is call non-pressure or Soft Wash process. The solution is applied with a 12 volt pump system with the average pressure of 60 psi and the rinsing process is done with a simple garden hose pressure or about 40 psi. Watch the videos to your right on how the process works and the equipment used.

As to the cleaning solution there is also an alternative that is non toxic and caustic. The cleaning solution is a Citric based cleaning solution ( not citric acid) that contains algaecide, mildecide and fungicide. Though cedar shakes only have 3% oil content when installed, there is a water base oil in the solution that helps rehydrated the shakes. This solution is not for sale as it was developed personally.

Cedar Roof Cleaning Costs

On average the cost of a cedar shakes roof cleaning should be about $0.50 a sq. ft. or less than 10% of replacement cost.

So when considering having your cedar roof cleaned do your research. There is a difference between someone who can clean a cedar roof and someone who is a cedar roof cleaner.

This is my sole opinion based on my research and years of experience with cleaning cedar shakes roofs.

Cedar Shake Roof Cleaning Minneapolis

What can I say? Bruce and Keith provided an exceptional service, and they are really nice guys too. Found out at 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. Place looks outstanding! Highly recommended.

Cedar Shake Roof Cleaning, St. Cloud, MN

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.

Customer Review

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.

Customer Review

Mr. Sullivan cleaned our roof that had not been maintained in 28 years. The roof appeared almost black, but after the cleaning the shingles were a beautiful light brown color. It really brightened out home. Knowing that the deterioration was stopped with this cleaning was wonderful news. I love my shake shingles and am so thankful for Mr. Sullivan's service to keep them healthy and long lasting for years to come. I feel the cost is a wonderful deal for what you are doing to preserve a beautiful roof. Mr. Sullivan was right on time and came all the way to Kansas City within just a few days of my initial request for an appointment. We was very professional and left our property better than he found it. Thank you, Mr. Sullivan!!!
