Exciting Properties of Cedar Roofs
Cedar has some fascinating properties as well. Sometimes in the late summer after the first rain, a home may experience a leak. Then through the whole winter, the leak is never seen again. The change is because, when the cedar is dry, it can shrink a little, and at the first season rain, the water drips in before the cedar has had a chance to soak in the liquid and swell. When wet, the cedar expands slightly, and that can sometimes seal the crack. Cedar is a beautiful natural roof. There are many attributes to shingles and shakes that come into play when deciding the proper roofing material for your home.
