Why Are Commercial Roofs Usually Flat?

Are you thinking about which type of roof you should choose for your commercial building? Flat roofs are the most popular choice for commercial buildings.

Despite the name, these roofs are not entirely flat — they have a minimum slope for drainage purposes. However, the slope of the roof is barely noticeable to the untrained eye. Keep reading to learn why commercial properties often have flat roofs.

Flat roofs increase building safety

As a commercial property owner, you should provide safe premises for building users. Usually, this means ensuring every aspect of your building construction is up to code.

Commercial buildings are typically large structures with long clear spans. The greater the roof slope, the more roofing material will be used, hence the heavier the roof. Heavy roofing material increases the structural loads and stresses on your commercial building, increasing the risk of roof failure.

A flat roofing system helps keep the roof load on a building at a minimum, preserving the structural integrity of the building and increasing the safety of building occupants.

Flat roofs are economical

Many business and commercial facility owners know that they must be financially prudent to succeed in their endeavours. Often, this means thinking long-term and saving money whenever they can. 

Flat roofs provide commercial establishments with durable, fully functional roofing systems without costing too much.

Since they require the least amount of roofing material to build, commercial property owners can save money on material purchases. Plus, flat roofs are relatively easy to install, adding to potential financial savings on roof installation expenses.

Flat roofs are easy to access

Since flat roofs are relatively flat, they help you make light work of roof maintenance and repair tasks. Roofing crews can quickly work on your commercial flat roof as the risk of falls from height is reduced.

Flat roofs provide functional space

As commercial real estate prices continue to spike, you'll want to make the most of the space on your commercial property. A flat roof allows you to create usable space above-ground. For example, you can store business-critical equipment such as air conditioning systems on top of your roof, eliminating the need to keep bulky equipment indoors or in the yard. 

Flat roofs are not the most aesthetic roofing option, but they offer benefits that compensate for this drawback. Get in touch with your local roofing contractor to get a quote for your commercial flat roof installation.
