The Weathering Cycle

The cycle begins when water penetrates the wood causing it to swell. Then blistering heat from the sun dries the wood leaving it brittle. This continuous cycle of expansion and contraction causes your wood to warp, splinter and crack. Over time, the cracks, caused by additional wettings or freezing and thawing, grow larger and larger. Exposure to the sun's harmful ultraviolet rays turn bare wood gray and uneven in color. Moisture from rain, humidity and morning dew creates an environment conducive to mold and mildew growth. Through the interaction of sunlight and rainfall, cedar shakes and shingles can lose virtually all of their natural preservatives in as short as five years. At this age, most cedar roofs show signs of cupping, curling, splitting and decay.

Preserving your wood roof will protect it from moisture and sunlight which are the greatest enemies of any wood surface. Remember, as long as your cedar is protected, it will not only look great but can double---even triple the life of your roof. With this extended life, you will obtain real savings and make your wood roof more cost effective.
