What Is Roofing?

Roofing is the process of covering the top surface of a building with a waterproof layer of material. Roofing felts are also called ply sheets and are usually reinforced with glass-fiber or organic mat. The bitumen between these sheets is either asphalt, tar, or a cold-applied adhesive. Asphalt and tar must be heated before they can be applied to the roof, while cold-applied adhesives do not.



There are three basic types of roofs: flat roofs, sloped roofs, and hipped roofs. Flat roofs are most commonly used in the American southwest, the Middle East, and other arid climates. The roof style is secondary to the ability to drain water away from the building. During the 19th century, new waterproof roofing materials and structural steel and concrete made flat roofs practical and widespread. They soon became the dominant form of roofing for residential structures and commercial buildings.


In a house, the roof covers the top surface and protects the home from rain and wind. A roof can be flat or pitched, vaulted, or domed. Different forms of roofing have different characteristics, and these factors may influence the choice of a particular roof. A flat roof offers sufficient weather protection without the added cost of a steep slope. However, a sloped roof requires a professional roofer to make it work.


Shingles are used on most buildings, including houses. They can be made of a variety of materials and are usually used for large-scale buildings. Shingles are traditionally measured in squares, and a single square is equivalent to about 100 square feet. A roof that is 2,500 square feet in area requires 25 squares of shingles. Roofing materials can also be made of wood or metal. Some of the materials used to cover a roof include plywood or metal sheathing, which protects the roof seams and supports the roof.


While the lifespan of a roof varies considerably, a typical asphalt shingle roof lasts fifteen to twenty years. Similarly, a three-tab asphalt shingle roof is designed to last between 30 and 50 years. A roof that is constructed of metal can last 80 years or more. The cost of this type of roofing is relatively low and ranges from $6 to $14 per square foot. It is also affordable, which means that if you need a new roof, it is the best option.


Another option for roof coverings is tile. Tile can be made of clay or concrete. The material is durable, and comes in different styles and colours. Spanish-style round-topped tiles are most common in the Southwest, but there are also flat tiles that give a French or English look to a building. The downside of tile is that it is heavy, so you must make sure that the roof structure can handle the weight of the tile. A professional roofer can help you determine the best option for your needs and budget.
