Cedar shakes and cedar shingles is CCA treated or not CCA treated. CCA means chromated arsenate of copper. CCA is a preservative that inhibits the growth of mold, mildew and fungus and helps keep insects from eating your beautiful cedar roof. CCA cedar can make your roof last longer, but CCA is NOT A FIRE TREATMENT. Cedar that has been fire treated is available, but the roofer will have to special order. CCA treated cedar normally cost 15 – 20% more than non-CCA cedar. Most cedar roofs are not CCA treated.
Handsplit and resawn cedar comes in two different grades and many different thicknesses. Premium grade cedar shakes or shingles are made of clear heartwood, and are 100% edge grain. Number 1 grade cedar is also made of clear heartwood, but it they have a maximum of 20% edge grain. Two of the most popular thicknesses of cedar shakes or shingles are heavy and medium. Heavy cedar has 3/4″ (19 mm) minimum thickness on the buttend, while medium cedar has 3/4″ (13 mm) minimum thickness. If you listen to the word “perfection” it has nothing to do with how much “perfect” heartwood the cedar contains. “Perfection” means the cedar shake or shingle is 18 inches long. Perfection shakes and shingles come in all 4 different classes.
