Flat roof: Advantages and disadvantages

A flat roof built horizontally although it may have a minor incline. Flat roof remains one of the most controversial roofing types. Mostly preferred in large buildings and outbuildings, the flat roof has both advantages and disadvantages. Before you install it in your house, take a moment and inform yourself on pros and cons it can brings by Georgia Roof Pro, leading roofing company in Lawrenceville Ga.


The cost of roofing: The flat roof’s key advantage is its cost. The cost of the structure, installation, and materials you need to build a flat roof is low because they do not have a pitch. They do not have rafters and engineered trusses that pitched roofs require, making them less costly because they need fewer materials. This makes a flat roof extremely affordable during its initial installation and the maintenance and upkeep.

Space on top: Once your flat roof is fixed, you can use the space on top of its to install your air conditioning units and solar panels, or create a rooftop garden or design a living roof.
Interior space: You can equally utilize the interior space. For instance, you can have an attic or a top floor apartment because space is readily available without the sloped walls that a traditional pitched roof would produce.

Accessibility: They are easily accessible than sloped roofs in case you need to clean your gutters, repair part of the roof or install equipment such as satellite dishes or solar panels at much lower cost.

Insurance: Insuring a company installing flat roofs is cheaper compared to one installing pitched roofs because a flat roof is harder to fall off.


Drainage: The biggest drawback of a flat roof is that they do not drain as efficiently as a roof with any kind of pitch. It means water has a tendency to puddle and remain on the roof, which could lead to the destruction of roofing material leading to eventual leaks, particularly along the seams.

Materials: Flat roofs limit the range of materials you can use. Most homeowners use bitumen, EPDM (ethylene propylene diene terpolymer), which is an extremely durable synthetic rubber roofing membrane and Thermoplastic Polyolefin (TPO), a single-ply reflective roofing membrane made from polypropylene and ethylene-propylene rubber polymerized. These materials are relatively affordable and easy to install.

Lifespan:  According to Georgia Roof Pro, Lawrenceville GA top commercial roofers the lifespan of a flat roof is limited in two different ways. One, most of the materials used in flat roofs have a limited lifespan of 10 to 15 years. Two, since they do not naturally drain, flat roofs last up to a maximum of 10 years. This would negatively affect your ability to sell the property. Also, this is because the next owner will likely be aware of the roof’s shortened lifespan.
Insurance: Since they are susceptible to leaking, insurance companies levy high premiums compared to, for example, metal roofs.

Heat absorption: Flat roofs absorb heat because they do not have pitch and the whole roof remains exposed to the sun all day long. Houses with flat roofs could cost you large amounts in power bills in summer months when your home’s air conditioner has to work harder to keep your home cool.
