Included in every estimate is ATCO clear Shakelast Preservative.
Although cedar is a naturally durable wood, it loses its protective chemicals
and resins through weathering. This is evidenced by a shake turning gray
and then black. The roof is then vulnerable to attack by moss, mildews,
fungus and insects. Water based ATCO Shakelast penetrates deeply into
shakes carrying a copper naphthenate solution which prevents decay, moss, mildew
and insect attack as well as controlling warping, swelling, shrinking, and end
checking caused by changes in moisture content of the wood. Treatment is
particularly important in areas where climate combines heat and humidity for
portions of the year, on roofs of a low slope, and roofs beneath overhanging
trees.
