Why Are Commercial Roofs Flat and Residential Roofs Sloped?

When it comes to the roof of a structure, you have virtually endless options. You can choose from a variety of roofing materials and types, each with its own customizable features. However, a broad distinction is typically made between commercial and residential roofs in Atlanta, GA. This distinction is on the basis of the angle of the roof.

Commercial roofs typically have a flat roof, often used for buildings that require a large roofing area to be covered. Residential roofs, in contrast, are typically pitched. Most skilled roofing contractors are well aware of these differences. There are sound reasons as to why each type of roof is used for each type of building. Here is a look at these reasons.

Flat Roofs for Commercial Buildings

Commercial buildings typically feature what appear like flat roofs. However, in truth, even the most flat-looking roofs have some slope. This is to allow for the proper drainage of the water and to prevent it from pooling on the rooftop. The drains on a flat roof are usually placed along the edges or in the middle of the roof, and the slope of the roof is slightly tilted that way. This encourages the water to move along towards the installed drains.

Flat roofs make sense for commercial buildings for a variety of reasons. Although they offer a blander aesthetic, they are useful in many ways.

Pros and Cons of Flat Roofs

One of the key advantages of a flat roof is that it is cost-effective. In comparison to pitched roofs, flat roofs cost a lot less. This is for a variety of reasons. It is possible to use more cost-effective materials when working with flat roofs. At the same time, no additional structures have to be erected to support the roof, as is the case in pitched roofs. This makes the installation of a flat roof quick and easy, while also costing less.

Another great thing about a flat roof is that it offers a plenty of space where A/C units and other outdoor pieces of equipment can be placed. This allows a commercial building to hide away the outdoor units instead of having them placed on the floor or in the parking lot.

Drainage is a vital concern for all roof types. And while residential roofs work fine with great-looking gutters, such an option is simply impractical for a large commercial roof. Flat roofs allow a commercial structure to use inexpensive drainage solutions.

On the downside, flat roofs add zero aesthetic value to a structure. Although drainage solutions for such roofs are inexpensive, they are also less than ideal. This is because water flow is gentler and slower given the very low slope. As a result, water leakage and other issues come up frequently with flat roofs. And ongoing maintenance is required to keep leaks in check.

Pitched Roofs for Residential Buildings

Pitched residential roofs are typically preferred for residential structures. One of the key reasons and benefits is that they offer an obvious aesthetic appeal. You can choose from a range of materials, from asphalt shingles to metal roofing and more, for a pitched roof.

A second advantage of pitched residential roofs is that they drain quickly and easily. When combined with well-installed gutters, you can effectively prevent roof leakage issues with such roofs. A third benefit is the additional attic space that becomes possible with a pitched residential roof. Unlike with commercial buildings, homeowners usually want more space inside, not outside. So the attic area can be used as storage and for a variety of other purposes.

Finally, a roof with a slope will require little overall maintenance compared to a flat roof. This is simply because water drainage becomes confined to the roof edges only.

Pitched residential roofs also have their downsides. The most notable of these is the cost. They cost more in comparison to flat roofs. Another disadvantage of a flat roof is that their maintenance or repair is not exactly simple or easy. So you will need to hire professionals to clean or repair a pitched roof.
