“For each year a shake roof goes untreated it loses three years off its estimated remaining life.”
U.S. Dept. of Agriculture
Most of the old growth, or virgin timber, has long since been logged. The new trees second growth, mature much faster and the growth rings are farther apart. The new cedar just doesn’t withstand the elements like its predecessors did.
The pitch, or slope of older homes were generally steeper than today’s modern homes. The shallower the pitch, the more likely water and debris are to stay on the roof rather than run off. The more moist the roof is, the quicker it rots.
Causes of Damage
SUN- Ultraviolet light attacks the wood fiber in the cedar and generates heat. This bakes out the natural wood binding resins, causing the shakes to become brittle.
RAIN- While water may stand on new or treated cedar during a rain, it soaks into the untreated wood like a sponge. The wood is damaged by being alternately soaked and dried out. If you have ever left any type of wood furniture outside for a long period of time, you can see what can happen to your roof. During the wet seasons the moist wood serves as a breeding ground for moss and fungus.
FREEZING- When the temperature drops below freezing, the water that has saturated into the wood fibers expands. As it thaws and freezes again, the damage to the wood’s structure is compounded. This situation is similar to winter time highway deterioration (pot holes!)
MOSS- Moss and fungus are high in acid content and retain moisture all year round that will accelerate the deterioration of cedar.
It is easy to recognize the deteriorating roof. As moss, algae, and fungi begin to feed on the wood, your roof has a dirty grey or sometimes greenish appearance. This is the ideal time for roof maintenance.
In more advanced stages moss appears on the butt ends of the shakes and algae and fungus growth is readily visible. At this stage, the roof can be saved if action is taken immediately. However each roof is different and should be inspected by a professional.
When an unprotected cedar roof becomes infested with moss, algae, and fungi, more than one-half of that roof’s potential life can be lost.
CLEANING PROCESS INCLUDES:
- Professionally powerwash the roof to remove all moss, algae, and debris.
- Clean out the gutters and downspouts.
- Moss and debris removed from decks or concrete if desired.
REPAIR PROCESS INCLUDES:
- Missing and decomposed shakes are replaced by our trained professionals with #1 grade cedar shakes. Ridge cap checked and secured. #1 cedar shingles are used under shakes that are in the process of going bad.
TREATMENT PROCESS INCLUDES:
- Your roof is treated with a wood preservative and moss and algae retardant. This treatment will provide your roof with protection from the following.
SUN- Treatment replaces the natural binder resin, adding significantly to the life of the cedar.
RAIN- Treatment penetrates deep into the cedar, replacing the natural water repelling chemicals lost through weathering.
FREEZING- Treatment prevents the water from saturating into the wood, thus preventing the freeze-thaw problem.
MOSS- Treated cedar is less susceptible to moss, fungus, and insects.
When Should Cedar Roofs Be Treated?
NEW cedar roofs should be treated within one year of installation. The best time is when they have weathered or lost their orange-brown color and turn light gray.
OLD cedar roofs can usually be restored if not more than one inch of the shingle butt ends have been destroyed. However, each roof is different and should be inspected by a professional. Also, prior to treatment, the roof should be cleaned using a high pressure power wash.
How Often Should Cedar Roofs Be Treated?
Proper application at four to five year intervals will insure a well cared for, healthy roof for a long, long time, depending upon which chemical you use.
