Understand the forces working against your roof
Maintaining your cedar roof requires understanding of the forces working against your roof. The sun, wind, rain and snow that your roof protects you and your home from, take a toll on your roof. The sun on your cedar shakes releases compounds within the wood that begin a slow process of degrading and weakening of the wood. The constant cycle of wet and dry, freezing and thawing from rain and snow alters the wood as well. Shakes swell when wet then contract as they dry. Additionally, rain and wind can carry small particles that can further stress the wood by exposing microscopic areas of new wood, gradually wearing the wood away. This can leave the wood open to organisms like mold, mildew and fungi which further degrade the shakes.
Lingering Moisture is your worst enemy
Of all of the elements battling your roof, the worst is lingering moisture. The faster and more completely your roof dries, the healthier your roof will be. Anything causing moisture to linger, like tree leaves or pine needles, needs be removed from your roof on a regular basis. Plant vegetation will hold moisture longer, promote mold and fungus growth which damage the shingles. Areas where the planes of your roof meet to form valleys are the most susceptible to plant debris gathering.
