While it’s common for residential structures to have pitched roofing systems, commercial properties are typically built with “flat roofs”. Firstly, these types of roofs are not actually flat. They’re built at a very low angle to comply with national building codes. Secondly, they are the better commercial choice simply because they are easier to maintain and install than their pitched counterparts.
But can you use metal for flat roofing systems?
Types of Metal Roofing
Coated metal shingles are the most common ones used in residential buildings. This roofing option is technically metal, but it is made to appear more like standard shingles. On the other hand, it’s more common to have standing-seam metal roofing for low-sloped construction as it’s specifically designed for this use.
Advantages of Metal Roofs in Commercial Properties
As with all roofing materials, metals comply with all the performance requirements of the National Roofing Contractors Association (NRCA). These include water resistance, durability and ease of installation. While metal roofs are more expensive up front, they more than make up for it with their extremely long lifespan and low-maintenance needs.
Other Low-Slope Roofing Options
Metal roofing systems remain in the top three choices for commercial flat roofs because of their practicality. The other two choices are bitumen-based roofing like asphalt and modified bitumen, and membranes like ethylene propylene diene terpolymer (EPDM). While each material has its own set of pros and cons, metal roofs tend to rate highly on the most common performance requirements, making them the number one choice for commercial property owners in certain areas.
