Fireproofing Wood Shingles
Certi-GUARD and CCA-Treated Wood Shingles
At Custom Shingles, we offer both Certi-GUARD and CCA-treated wood shingles that ensure your wood roofing is never at risk of fire. Different areas around the country have different building codes and requirements, and we can offer a custom solution that meets those codes and requirements while still delivering the beauty and longevity that custom wood shingles are known for.
What Is CCA?
CCA stands for chromated copper arsenate, which has been used to treat timber for more than 80 years. CCA includes copper, arsenic and chromium, and it’s typically used as an oxide or salt. When applied to timber, it leaves behind a recognizable green residue. CCA is one of a few different treatments that can be used to create fireproof cedar shingles. As mentioned, different areas have different codes and requirements, and CCA is often an accepted and effective form of fire treatment for wood shingles.
What Is Certi-GUARD?
When measuring the effectiveness of pressure-impregnated fire-retardant roofing systems, you’ll find three accepted classifications: A, B and C. Certi-GUARD is a labeling process that identifies cedar shingles and shakes that meet testing standards related to each of the three classifications. Class B shakes and shingles receive a red Certi-GUARD label, while Class C shakes and shingles receive a blue Certi-GUARD label. Class A fire-rated wood roofs are only achieved through a component roofing system, so no individual shakes or shingles can achieve a Class A rating. A Class A wood roof is typically composed of class B shingles with a highly fire-retardant underlayment, but technology to create Class A shingles is being introduced to the market.
The Benefits of Certi-GUARD and CCA-Treated Wood Shingles
Why would someone choose Certi-GUARD or CCA-treated wood shingles? They offer a number of benefits, not the least of which is their ability to prevent deterioration and fire. The treatment should not affect the color of individual shakes and shingles over the long term.
The possibility of fire is one of the great concerns about a wood roof, but this concern is often unfounded. Properly treated wood shakes and shingles are no more at risk of fire than any other roofing material, and the vast majority of cities, municipalities and other entities that manage building codes welcome the addition of wood roof homes to their communities.
Who Makes the Rules?
How are the thresholds for Class A, B and C determined? The Cedar Shake & Shingle Bureau (CSSB) has been in operation since 1915, and it promotes manufacturers of wood shingles and their commitment to meeting the highest of quality standards. Since the 1980s, the CSSB has worked with third-party, independent quality-control agencies to inspect mills on a regular basis. The CSSB established the grading and classification process for shakes and shingles, and the independent inspections are focused in part on ensuring that mills are adhering to these quality-control standards.
If you have any questions about the fire-retardant qualities of wood shake and shingles or custom wood roofing in general, the CSSB is a resource for the public. It is the authority on wood shingle roofs, and its knowledgeable staff is always available to answer questions and provide general support to companies working in the wood shingle roof industry as well as the customers they serve.
