When it comes to choosing a roof for a commercial building, a majority of property owners choose flat roofs. Flat roofs can be fabricated from a variety of different materials and offer a number of benefits for commercial properties. It’s important, however, to understand the advantages and disadvantages of a flat roof before making a choice.
The Advantages of Flat Roofs
One of the primary reasons commercial properties choose flat roofs is cost: it’s simply cheaper to install. Because of the shape, there is less surface area and therefore labor and fewer materials involved in construction than with a peaked roof. Flat roofs are often not completely flat: they slope enough to allow for rain runoff, but not enough to make it difficult to access them.
Additionally, flat roofs make it easier to accommodate the commercial heating, ventilation, and air conditioning (HVAC) needs of a facility, or even solar panels to cut down on energy costs. These types of services can be located on peaked roofs, but the maintenance and repair of such structures become more difficult and expensive.
Finally, a flat roof can offer extra space to a company that needs it, perhaps in the form of a rooftop relaxation area or even gardens for workers.
Types of Flat Roofs
There are several options when it comes to installing a flat roof. Each will have advantages and disadvantages, including cost.
Single-Ply Roofing. This is a popular option for flat roofs because it’s less expensive and can be long-lasting when properly installed. It uses waterproof membranes composed of EPDM, PVC, or TPO.
Built-Up Roofing Systems (BURs). This type of flat roof is comprised of many layers of industrial-grade cloth, felt, or paper coated with asphalt or coal tar for waterproofing. It tends to involve a moderate cost outlay and is a popular choice for commercial flat roofs.
Modified Built-Up Roofing. While this option, comprised of many layers of asphalt and polymers, maybe a more expensive choice, it’s also the best option for constructing a weathertight design for a commercial building.
