When new, cedar shakes and shingles display natural honey and cinnamon tones, and will later mature to a seasoned and distinguished-looking silvery gray when properly maintained. Cedar roofs don’t decay, but they do weather. Cedar has natural preservatives that resist moisture, decay and insect damage. Although in warm, humid climates and on heavily shaded roofs, algae, moss, mold, mildew, lichen and fungi’s will grow, because these organisms retain moisture the cedar will decay in time if not maintained.
When Should A Cedar Roof Be Cleaned?
Cedar is a natural insulator against the environment; competitors can’t come close to the thermal efficiency of wood. In fact, cedar has twice the thermal resistivity (R-value) of asphalt, 5 times that of slate, 8 times that of concrete, and hundreds of times that of metal and aluminum. If the shakes or shingles display a brown/dark brown to black tones, these are signs of harmful organism infestations and they need to be cleaned.
Cedar Maintenance Your cedar should be maintained every 5-8 years to keep it in ideal condition. Missing and cracked shingles should be replaced as soon as they are noticed. We do not recommend any sealing be done as your roof needs to breath and expel built up moisture. Your roof will eventually turn a beautiful silver color after cleaning. This is a natural process which cannot be stopped without doing damage to the wood. Your cedar can be stained, but we do not recommend any stains which are sealants and eventually the wood WILL look blotchy as the stain leeches out. If you wish your roof to retain the wood tone look, we recommend our process be done more frequently.
Cedar wood, like your teeth, is organic and need to be cleaned to stay healthy and last a lifetime. When properly maintained, cedar shakes will last anywhere from 40 to 60 years.
