Flat roofs are the most common type of roof found on commercial buildings. They are used on low-sloped roofs with a slope of less than 3/12 (three inches per foot). Flat roofs are solid and durable, but they must be maintained properly to avoid leaks or other damage.
Flat roofs are generally considered the economical choice for commercial buildings since they provide a large amount of usable space. They also do not require any complicated structural elements, such as gables or dormers, which can add to the cost of installing other types of roofs.
The main disadvantage of flat roofs is that they require more extensive maintenance than other roofing systems. In order to keep your roof maintained, you'll need to hire a professional roofing company like Excel Renovation.
