Some basic roofing supplies are a black paper membrane, metal flashing, shingles or tile, and metal trim. The black paper membrane is generally installed prior to any other roofing materials and is laid directly over the plywood to protect and insulate it from extreme temperatures. The flashing is then installed over the membrane in places where water may collect. Flashing is generally composed of galvanized metals like copper or steel to prevent the flashing from rusting.Continue Reading
Once the flashing has been placed, then the chosen roofing material is installed. One of the most popular materials are asphalt composition shingles because of their durability and overall appearance. Other types of roofing materials are wood shake, galvanized steel sheets, slate, composition slate and ceramic. Asphalt composition shingles are generally believed to be less durable, only lasting for up to 50 years, whereas slate can last for 100 years or more. However, asphalt composition shingles are much more affordable than slate and lighter which reduces the amount of overall stress on the roof.
Once the shingles or tiles have been installed the trim material is installed over the seams around the roof to prevent water from leaking into the spaces between the roofing material and the plywood. Trim material is usually composed of galvanized metals such as those used in the flashing.Learn more about Tools
