Flat Roof Systems Need to Have Proper Drainage in Order to Remove Pooling Water

What is the Best Flat Roof System?

There are a number of different flat roof systems. Flat roof systems include PVS, TPO, EPDM Rubber, BUR (Built Up Roof) modified bitumen, and spray on coating. Each of these roofs comes with a different set of roofing materials and treatments. Depending on which area of the country you are located, you may want to select a flat roof system that is engineered to perform better in your climate. 

How Long do Flat Roofs Last?

Flat roof systems can last longer than one might think, provided that they are expertly installed and receive routine maintenance. The general estimate for a flat roof timeline is approximately twenty-five years. Flat roofs generally come with a ten to twenty-year warranty, however, flat roof systems can last twenty-five years if properly installed and maintained. 

What are the Different Types of Flat Roofs?

In truth, there is a wide variety of flat roof systems. This segment will focus on the most common types of flat roofs. The first is BUR or a Built-Up Roofs. These roofs have been around for over one-hundred years in the United States and are often distinguished by their tar and gravel composition. Modified bitumen roofing is similar to a built-up roof in that it is composed of asphalt rolls usually three foot wide. Modified bitumen roofs can be installed in four different ways. EPDM roofs are another flat roof system that is distinguished as being composed of rubber. These rubber roofs adhere to the top of the roof. Yet another type of roof is known as SPF or Spray Polyurethane Foam.

During installation, special polyurethane foam is sprayed on the surface of the roof and then coated with some type of waterproofing elastomeric topcoat. PVC and TPO are single layers of material that are usually white or grey. These membranes can either be adhered like EPDM or mechanically attached with screws and plates. While having a good roof is necessary, so can be central air conditioning. Central air conditioning installation is necessary for many different regions of the country. If you find that your central air conditioning is failing, it may be time for a replacement.

Is a Flat Roof a Good Idea?

When comparing flat roofs and sloped roofs, it’s important to consider how rain and weather will affect the surface of the roof over time. With a sloped roof, tree branches, rain, and snow have a downslope to eventually navigate their way off of the roof. With a flat roof, this process is understandably more difficult. Without proper drainage, water can pool and puddle, causing damage to the surface of the roof membrane. More roofing maintenance is necessary for a flat roof, because debris tends to collect, and the surface must be clean and tidy in order to maximize efficiency. 

What are the Disadvantages of a Flat Roof?

While there are certainly advantages to having a flat roof, there are a few disadvantages as well. Please browse through the following disadvantages of flat roofs to keep yourself aware of possible pitfalls.

  • Drainage. Flat roof systems can be installed with excellent drainage, however that does not necessarily mean that they will drain as efficiently as a flat roof system. This could lead to the roof breaking down over time due to the weight of water, or degradation as a result of pooling water.
  • Longevity. While there are many different types of flat roof systems, all of them have relatively short warranties. A limited lifespan of ten to fifteen years means that the roof will need to be replaced sooner rather than later.

Flat Roof Systems for Residential

If a homeowner owns a property that has a low pitch or a flat pitch, there are many different types of options that are available for their new flat roof system. Rubber roofs, for instance, are a very popular application for homeowners. EPDM roofs tend to be relatively inexpensive, and are waterproof and fairly easy to install. Another kind of roofing is Built-Up Roofing. These are most often used in commercial and industrial applications, however they can be streamlined for residential use. MBS, or a modified bitumen system, is one of the fastest growing and most popular flat roof systems, and uses a special combination of coated basemat layers to seal the roof.

Flat Roof Systems for Balconies

Roof terraces and balconies are an exceptional solution for making the most out of outdoor space. Balconies open up a whole new outdoor space for your home, increasing your amount of entertainment space. With proper drainage, many singleply membrane flat roof materials are available for your flat roof system.

Flat Roof Systems You Can Walk On

PVC is known as a stronger, tougher membrane than EPDM. Additionally, PVC does not oxidize under ultraviolet rays. When installing a PVC roof over an EPDM roof, please always make sure that the previous roof is completely removed, and that the underlayers are clean and ready for a new application of roofing material.

Flat Roof Systems Can Be Adhered in Different Ways

Flat Roof Systems for Commercial Buildings
