Advantages and Disadvantages of a Flat Roof

Flat Roof Basics

Flat roofs are constructed of an under layer and a top coat. There are always two parts and the proper sealing of them is critical to the integrity of the roof. The coating can be a PVC-like synthetic rubber coating, asphalt or a modified bitumen. All of these coverings need to be checked regularly to ensure that the roof stays leak free. Flat roof styles are typically seen in warmer weather climates, as most could not stand the weight of winter snow build-up. They are architecturally appealing and can be economical if used in the right setting while being properly maintained.

Advantages of Flat Roofs

Flat roofs have some distinct advantages over their sloped counterparts. One of the most obvious advantages is that flat roofs are easier to climb up on and inspect. Although any excursion to the roof should be dealt with using care and caution, flat roofs offer significantly more stability and horizontal surface than sloped roofs do. Another benefit of flat roofs is that they are cheaper to re-coat and install than sloped roofs. However, this is a tricky point, because flat roofs need to be re-coated and sealed every few years to help them maintain their integrity and prevent leaks. If the roof is not properly cared for, there can be a need for replacement much sooner which would make a sloped roof actually more cost effective.

Disadvantages of Flat Roofs

Depending on the structure, flat roofs can be a distinct disadvantage. The larger the area that the roof is covering, the less stable it becomes. Although many businesses and industrial buildings have flat roofs, they have to compensate for the weight of the roof on the interior. Flat roofs, especially those that are large, also have extreme difficulty bearing the weight of snow accumulation and heavy rain. It is not uncommon to see news stories about flat roofs collapsing under the weight of Mother Nature's fury. If the roof will be installed on a residential home in a dry climate, the odds of it lasting for a long time are much greater. When deciding whether or not to install a flat roof, take the advantages and disadvantages into consideration. Also consider the amount of time and effort required to maintain the roof and use that to help determine whether such a style is feasible or not for your home or business. When installed on the right building in the right climate, a flat roof can provide distinct architectural appeal and practical roof covering.
