Flat roofs are common on commercial buildings. They have little-to-no slope but can vary by design style and material. Whether you’re building a new property and are considering a flat roof installation or want to have an existing flat roof redone, consider the following information about this type of structure.

Types of Flat Roofs

There are a variety of flat roof designs. Built-up roofs (BUR) are one of the most common. They use an affordable, durable gravel topcoat over an insulation layer—an excellent feature for indoor climate control.

PVC roofing works opposite of BUR roofing by deflecting exterior heat rather than containing interior heat. It’s one of the most water-resistant options, which can increase longevity and reduce the risk of incidents.

Spray-applied roof coating is one of the easiest materials to install. It’s eco-friendly and water-resistant. Its design also holds the same climate-control perks as PVC and BUR roofing, so you can expect long-term savings.

Modified bitumen is a long-time favorite that works similar to PVC. While less durable, it can fulfill basic roofing needs on smaller commercial properties.

EPDM roofing works like PCV, though uses rubber instead of plastic as its base material. This provides greater durability. Because the roof installation leaves seams behind, it can be more prone to leaks if you don’t stick to an inspection and maintenance plan.

Benefits & Purpose

The most immediate benefit of flat roof installation is cost. These options are much more affordable than pitched roof designs. They’re also easier to install and maintain because of the flat working surface.

Flat roofs also increase usable space. Commercial properties can install large ventilation systems, install HVAC units, and even create amenity spaces, such as roof decks. Inside, the large, flat ceiling creates more working space for lighting, ductwork, and other fixtures.
