Flat Roofs
Most roofs used in commercial buildings are flat roofs. There are many reasons why these are used more in commercial buildings than other roof types, but their cost-effectiveness is a critical factor. Flat roofs do not require as much material as other roofs because there are fewer square feet to cover before the roof is complete, this makes them much quicker and easier to put in place.
Buildings that are powered through renewable sources such as solar or are dependent on satellite dishes may also find it easier to use a flat roof rather than other types because it is far easier to install such systems on this roof type. However, flat roofs are not perfect designs, and draining is a major issue. As the water gathers on the surface of the roof, the material used to build it can easily get damaged and cause leaking.
Pitched Roofs
Pitched roofs are more common than the other roof types because people also use them in their residential houses. However, they can also be used for commercial buildings. Much like in residential homes, pitched roofs in commercial buildings are used when good drainage is necessary. As pitched roofs can be quite steep, it is easier for water and snow to run off their surface. Commercial buildings with this type of roofing will hardly experience any leaks or mold.
However, pitched roofs are not perfect. As you can imagine, installation and maintenance of a highly sloped roof are more difficult than a flat roof. If you want to install a pitched roof for your commercial building, then you must be aware of the necessary safety procedures required. This will all lead to a higher cost of installation, and if you need to carry out any maintenance or repair, then you should also be prepared to pay more.
Low-Sloped Roofs
The low-sloped roof is often used for commercial buildings such as factories and warehouses. These buildings are a combination of the flat and the pitched roof, as they appear flat but also have a modest pitch. This design solves the main advantage of flat roofs because it allows you to direct where the water should go. At the same time, it also uses fewer materials than the higher-pitched roofs because of a reduced surface area.
If you want to use a low-sloped roof for your commercial roof, then you should be sure to check the building codes in your area or consult your commercial roofing contractors. If your building is an area that snows heavily, then you should be wary of this roof type as the snow will not melt easily. This can add extra weight to the roof, making it a hazard.
