As you already know, roofing materials keep water from penetrating into the roof structure. There is a wide range of roofing products available on the market today. For example, asphalt shingles, which are made by impregnating a dry felt with hot asphalt, are used in some houses. Other houses use wood shingles, such as red cedar or redwood. A large number of houses in California use interlocking clay tiles as roofing materials. Investigate the properties and characteristics of various roofing materials.
