Cedar Roofs

Cedar shakes have been used as a roofing material for centuries for two major reasons. First cedar provides superior insulation, and second the wood itself contains high amounts of natural preservatives. The presence of these natural preservatives has led cedar roof owners through the years to believe that their roofs needed little or no maintenance. The truth is that these natural chemicals are depleted over time and do need maintenance.

Over the years, rain extracts the natural preservatives from the wood and leaves it vulnerable to accelerated deterioration. As the preservatives are decreased, water enters the wood, causing the wood to expand and contract. This expanding and contracting creates cracks in the wood and provides places for algae, moss and fungi to take root. These living growths further deteriorate the wood as they draw food from it. Left unattended their spread will lead to premature roof failure. Sunlight is also a major problem for cedar roofs. The sun’s rays break down the wood at a cellular level. As the cells are broken down on the top layer of wood rain washes these cells away. This continuing cycle leads to the “graying” of cedar over the years. While many see this as the natural charm of cedar roofs, it is actually a visual signal of the deterioration of the wood itself.

If a cedar roof does not receive any maintenance it may last 10 years or more, depending on the severity of the elements. On the other hand, cedar is the only roofing material whose life can be prolonged by proper maintenance and preservation techniques. Basic cedar roof maintenance includes debris removal, cleaning to remove algae, fungi, moss, etc., and application of a wood preservative.
