Just like any other roofing system, a cedar shake roof requires periodic maintenance. However, cedar shakes require special attention.

Some recommend high-pressure washing or “powerwashing” the cedar roof, albeit it can damage the latter if not applied properly. As much as possible, a professional should assess the roofing system on a case-to-case basis if it qualifies for powerwashing. The assessment entails factors such as the age of the roof, gallons sprayed per minute, and pressure per square inch.

Moreover, if the cedar roof retains moisture, fungi infestation or mold growth can occur. Those, in turn, can compromise the integrity of the shakes and lead to water and structural damage. That scenario can be resolved by cleaning out the moisture and removing the infestations, which allows the roof to breathe again.

Another way to maintain the cedar roofing is to use a water repellent treatment product to clean and preserve the cedar wood. Professionals recommend using an EPA-registered wood preservative and checking its material safety data sheet for precautions. With proper maintenance, a cedar roof can last from 40 to 60 years – or even more.


While some homeowners can do these maintenance methods their own, it helps to call certified roofers to do the job. This ensures superior and long lasting results to preserve the durability and aesthetics of the cedar shakes.

  1. I absolutely agree with your last point on this post. It's always best to hire a professional to head any cedar shake roof repair that might pop up. Because cedar shakes need the "special attention" that you pointed out, I wouldn't trust myself with maintaining them.

  2. I hardly see cedar roofs where I live. The majority of the homes have asphalt shingles. This information to good to know just in case you ever had a home with cedar, you would know how to take care of it properly.

  3. The most recent alternative to cedar shake roofing is composite shake roofing tiles. For many years traditional cedar shake roofing was the roofing material of choice for many homeowners. Lately people have been rethinking cedar shake roofing shingles because of the cost and fire safety, and have turned to composite shake roofing, which is available in many colors and styles that are easy to install and is less expensive.
