In earlier times, wood roofs were a commonplace sight since not many other roofing options were available. Times have changed, and wood shakes and shingles are now considered luxury products that actually cost more than many other roofing materials. Today, wood roofs are chosen because of their natural beauty and weather resistance. Wood shakes and shingles are costly to purchase and install; however, your Mount Pleasant roofing company can instruct you on the best ways to prolong the life of your wood roof and get the most value out of your investment.
Over time, a wood roof will weather from exposure to the elements. Your shingles or shakes will gradually turn silver, gray or brown as they weather. Many homeowners love the rustic appearance of weathered wood; however, if you want to slow down the rate of weathering, a pigmented finish can be applied. These finishes can add a touch of color to your wood roof and reduce weathering and decay.
Not every conventional wood finish is appropriate for a wood roof. Common treatments like varnish, paint and shellac will crack from the swelling and shrinking caused by exposure to weather. When water seeps through these cracks, it will become trapped under the layer of finish and eventually rot the wood. It is also difficult to refinish the wood after these treatments are applied.
Most roofing contractors agree that the first coat of finish should be applied before the shakes or shingles are installed on the roof.
