4 FAQ About Flat Roofs & Commercial Properties

If you own a commercial property, it’s important to take measures to ensure that the building is safe and strong. One of the most vital elements your structure may need is a properly installed flat roof, which differs dramatically from standard sloped roofing installations. Here are the answers to four questions that contractors often hear from owners about this part of their constructions.

Top FAQ About Flat Roofs & Commercial Properties
What are the advantages of a flat roof?
Commercial property owners typically select flat roofs because they’re more practical for large buildings. Smaller structures, such as homes, can easily support the weight and design of a sloped silhouette. Flat roofing installations, by contrast, are highly sensible for commercial purposes. They’re economical, quick to install, and provide ample space for other uses, such as storing air conditioning units or solar racks. Some businesses may even choose to transform the space into a living roof. A restaurant, for instance, may use the space to cultivate an herb garden.

What materials are commonly used?
There are several materials used in the construction of flat roofs, including spray coating, modified bitumen, and ethylene propylene diene monomer (EPDM) rubber. These durable materials are designed to withstand common issues like water damage and leaks. Both modified bitumen and spray-on systems are especially popular because they’re quick to apply to the surface.

How are flat roofs maintained?
Have a roofing company come out and inspect the roof at least once annually. Routine exposure to the elements, such as the sun’s potent ultraviolet (UV) rays, heavy rainfall, and snowfall, can slowly take their toll on different materials. Because drainage can be a problem on a nearly flat surface, moisture tends to accumulate and remain there. As standing water collects, it can weaken the material underneath and cause leaks, leading to significant structural damage. Make sure that your roofing installation team installs a drainage system that redirects water to a proper outlet.

What are the design elements to consider?
Aside from slope grade, drainage, and insulation bear in mind that a reflective roof coating is designed with pigments designed to block UV damage. The more reflective your roof, the less you have to worry about roof repairs, energy consumption, and estimated life expectancy of the materials.
