CCA Pressure Treated Cedar Shingles and Shakes

While naturally resistant to rot and decay, Western Red Cedar shingles and shakes that have been treated with Chromated copper arsenate (CCA) will add years to the life of your roof or siding.

To add longevity to this cedar roof, the cedar shakes were treated with CCA pressure treatment

Invented in the early 1930s, CCA treatments protect wood against insect attack and fungal decay and is expected to give life to the wood in excess of forty years.  This can be extremely helpful in areas with high humidity to provide longevity to cedar roofing, utility, highway, marine, agricultural and heavy construction.  CCA preservative treatments render the wood useless as a food substance for insects and fungi yet keeps the natural look of the wood.  As a matter of fact, it is almost impossible to tell that the wood has even been treated when finished.

Since CCA pressure treatments have been around for so long, many studies have been done to ensure its safety by both private and public research institutions.  At no time have any special risks been found, and it is not toxic to plants.  However, it should not be used in direct contact with food, nor should it be burned.  As with any wood, a dust mask should be worn when sawing or working with CCA-treated cedar shingles and shakes.

CCA Pressure Treated Cedar Shake Roof will last approximately 40 years

    is there supplier local to the Washington DC area for your product? Looking for a Cedar Shake Number 1 grade 18″ tapersawn shakes. Must come from a member of the CSSB and be prefinished with a water repellent preservative. What is the warranty?

    • Hi John,

      Thanks for reaching out. We do not have a supplier in WA DC, but we do ship our products all over the US. Providing shakes from a CSSB mill is no problem, however, at this time we do not have a source that provides a water repellent preservative.
