Commercial Roofing: The Benefits of a Flat Roof System

When it is well maintained, a flat roof system is an effective solution minimizing the cost of roof repair. If you are constructing a new building, or placing a new roof on an existing building, below are seven reasons to consider implementing a flat commercial roofing system:

Low Cost – Compared to an angled system that has hinges or metal panels, a flat system requires few construction materials. Consequently, it typically costs less to purchase than an angled roof. Fewer construction materials can also translate into reduced labor cost and waste removal cost.

Easy Access – Due to its minimal slope, a flat system is easier to access for maintenance and gutter cleaning. This means that a building's maintenance personnel may be able to perform certain tasks that would otherwise require the assistance of a roof service.

Solar Panels – Large, horizontal surfaces are ideal for the placement of solar panels. On angled versions, solar panels absorb less energy due to the roof's angle in relation to the changing position of the sun. Because solar panels lay almost horizontal on a flat style, they absorb the maximum amount of sunlight.

Wind Resistance – Due to their level contour and seamless covering, flat commercial roofing systems display better wind resistance than angled systems that have shingles or panels. Over time, this resistance can result in less money space on replacement materials and service calls to a roof repair company.

Lifespan – Depending on its composition, a flat roof system can last for over a decade. As long as the materials are well maintained, systems composed of tar and gravel have been known to last for thirty years, and some tar and gravel systems are still in place from the early part of the twenty century.

Green Roofs – A green version uses soil, grass, and plants to form an organic layer of insulation on top of the roof membrane. In addition to improving the energy efficiency of a building, acting as a noise buffer, and making a building more attractive to employees, a green system can also increase the real estate value of a building.

Equipment Space – A flat system makes it possible to locate condensers, air handlers, and other HVAC equipment on top of a building instead of inside it or inside it. Placing HVAC equipment on top of a building can be a valuable noise reduction strategy for buildings where HVAC equipment can not be located on the ground or mounted on exterior walls.


If you need a commercial roofing system that can reduce the need for roof repair and provide a variety of practical benefits, a flat system may be the answer. In addition to helping reduce the money you spend on maintaining a system, a flat system is easy to access, offers an ideal space for solar panels or a green roof, and offers good wind resistance.
