Pressure treated cedar roofing is treated with a superior fire retardant, which is pressure impregnated into the inner cells of the wood, resulting in a permanently fire resistant product.
Treated cedar offers a beautiful alternative in areas where a fire rated assembly may be required, or for any homeowner who wishes to add durability and peace of mind to their home.
IMPORTANT: It is well-known that the selection and application of paints and stains to fire retardant treated wood products must be done with great care. The chemicals of some coatings adversely interact with the fire retardant resin either upon initial application or after weathering resulting in lowered fire retardancy of the product and/or unsatisfactory adhesion, durability or appearance of the coating (including leaching chemical residue).
