No matter the age of a building, a roof is one of its most important components. Not only do they shelter the building from outside weather, but they also visually make or break an entire historic building. Moreover, when certain systems like air conditioning or mechanical penthouses are added to buildings, the roofs also need to suffer some changes.
Old buildings basically have two types of roofs: sloped or flat. The exact design of a roof depends on various factors, such as the size of the building, its height, structural elements and the type of materials that are used.
According to a local Castle Rock commercial roofing company near me, among the most commonly used materials for old buildings we could mention slate, clay tile, asphalt shingles, wood shingles and metal. This is largely the case for sloped roofs. For flat roofs, the types of materials may include rubber roofing and built-up roofing systems.
Back in the nineteenth century, the most frequently used roofing materials included copper, terne plate and lead. Later on, in the early twentieth century, galvanized steel and zinc were also introduced.
Clay tiles are generally used for sloped roofs, and can come in colors such as red, gray or green. Asphalt shingles are also a popular choice, which can come in red, black or green.
