Types of Roofing Systems

Roofing systems come in many different materials. Some types are more eco-friendly than others. For instance, turf roofs, also known as sod roofs, are a good choice for buildings that want to reduce their impact on the environment. This type of roof uses soil and vegetation to act as living insulation, reducing the heat and humidity inside the building. Other roofing options include adobe, which is composed of clay mixed with a binding material. These types of roofs are usually used in low-rainfall areas.

Asphalt roofing is another common choice for flat roofs. These are generally the least expensive of the different types of roofing materials and are popular with builders on a budget. Roofing materials for flat or sloping roofs can also be made of metal or rubber. However, shingles remain the most popular choice for homeowners.

Roofing materials differ according to their composition and weight. Composition shingles are the most common type of roofing material in the United States. These shingles are flat, rectangular pieces that are laid in courses. They overlap each other and overlap the joints below. Different materials are used for shingles, including wood, slate, and metal. In Europe, they are commonly known as ceramic roof tiles. However, in parts of Asia and the United States, shingles are more common.
