4 Reasons Low-Slope Roofs are Better for Commercial and Industrial Buildings

With all the hype surrounding low-slope roofs and different materials that go into them, there are practical reasons why a low-slope option is a better option for a commercial property than a pitched roof. Below we explore four of the most common reasons:

Low-Slopes are Accessible

While pitched roofs are ideal for residential properties or smaller commercial buildings, they are not easily accessible. What this means is that you can add very little to the roof and it can’t be used for any other purpose other than to cover the building.

By contrast, low-slope roofs offer added space for building owners who may want to utilize the roof for component placement or even added inhabitable floor space. For instance, AC units are often placed atop a commercial structure. Building owners may also use the roof as an opportunity for adding a deck, a pool, or any other recreational item. It’s a more efficient use of space.

2.They’re Easier to Maintain

Once a flat roof is set in place it will require less maintenance over the years than a pitched roof. Commercial and industrial roofs are built with high-end materials that can withstand the most intense weather conditions over extremely long periods. Therefore, maintenance costs are reduced annually.

This option requires less labor because they are easier to navigate than pitched roofs. It’s also easier to spot leaks and other issues such as seams coming apart, warped materials, outdate flashing, and other components. Roofing contractors can get the work done on in half the time that it takes on an inclined surface.

3.They’re More Affordable to Build

Considering that most slanted roofs are made for residential properties, comparing them to low-slope roofs is almost like comparing apples to oranges. Designing a pitched roof for a large commercial structure, however, would cost you almost twice as much as it would just laying down a leveled surface. When you consider the design time, supplies, and labor involved in erecting a slanted alternative, you’ll discover that it’s more cost effective to keep your roof level.

4.They’re Space Efficient

Most commercial properties contain large floor spaces. This means that canopies can span hundreds or thousands of square feet on a single building. The roof structure has to be strong enough to support the roofing material. But the greater issue here is space efficiency. The fact is, most business do not need additional attic space or floor space beyond the initial level.

Consider this: a commercial building that is 100 feet by 200 feet with only a 4/12 pitch would create a roof that is over 16’ tall. Most of the space would be unused, therefore, a waste of time, money, and labor. Business owners would also incur needless additional maintenance and repair costs.
