We will be aware of more benefits of the flat roofing later in this article. Now we will know more about the types of this roofing system.

    Types of Flat Roofing

    Built-Up Roofing (BUR): This is a conventional type of roofing. The process will involve an application of the asphalt-based roofing tar and roofing felt. They use multiple layers to make the roof more durable and solid. On the top, they use a reflective coating or gravel to make the roof more energy efficient. It will ensure durability as well. Repair and maintenance are easy with simple coating layers.

    Modified Bitumen Roofing Diagram

    Modified Bitumen: Modified Bitumen can be ideal for small-scale commercial and residential roofs. As it has 3-ft rolls, this system is easy to install or apply. The surface of this roof needs a reflective coating to reduce the heat and for enhanced durability.EDPM Roofing Diagram

    EPDM Roofing: This type of roofing is highly effective. It is popular for energy-efficiency benefits. EPDM can reduce the cooling costs up to fifteen percent. The material is durable and does not demand much maintenance. It can last for more than two decades with minimal upkeep. As the dark tone can absorb more heat, it is always suggested to apply a reflective top to make this roof more energy-efficient.

    PVC Roofing Diagram

    PVC Roofing: It comes with a single-ply roofing material that is made from polyvinyl chloride. This material is used in the plumbing pipes. Both PVC and EPDM are used more in commercial roofing for their high-performance and durable benefits. PVC has some unique qualities. This material is naturally white and that makes it naturally self-reflective without using any extra coat. The natural heat-reflective qualities make this type a preferred choice for larger commercial roofing.

    TPO Roofing Diagram

    TPO Roofing: TPO or thermo-plastic olephine roofing comes as the chemical composition. This is a fabric-like material that comes in different roll sizes. The availability of different sizes makes TPO a good choice for different sizes and types of roof projects. Another benefit of this type is cost-effectiveness. You will have to spend less on TPO compared to the PVC or EPDM. However, it has a long way to go to prove the efficiency and performance.

    Spray Polyurethane Foam Roofing Diagram

    Spray Polyurethane Foam (SPF): This type is a bit different from the above-mentioned flat roofing systems. It combines flashing and insulation in addition to the roofing. During the process, the contractor will not tear off the old roof. Instead, the contractor will use SPF technology to spray a layer of foam. The high-density foam layer will bridge gaps and seal leaks to make a waterproof blockade. The final cured form will come with a good insulation value. This type will reduce the cooling and heating costs significantly.

    Benefits of Flat Roofing

    The flat roof system is widely appreciated for many unique benefits. One of the reasons for increasing popularity is cost-effectiveness. These are less expensive compared to the sloping counterparts. Also, you can expect more horizontal space and stability. You can integrate some building elements into your flat roofing to get more valuable space. This roof system is easy to install and inspect. The maintenance demands will be less as well. Here are some key benefits of flat roofing that you might consider.

    • Cost-effectiveness
    • Different types of constructions
    • Easy to maintain and repair
    • Minimal upkeep and durability
    • Energy efficiency
    • Easiest and fastest installation
    • Best for limited spaces and restricted budget

    Disavantages of Flat Roofs

    There are several drawbacks when it comes to flat roofs. Here are some of the examples of the disadvantages:

    • Buildings with flat roofs have less stability. Being there is no pitch, the ability to withstand weight can be compromised. Have your builders compensate this flaw elsewhere to strengthen the building.
    • Flat roofs do not drain water as easily as a pitched roof. Your roofer may require additional components to ensure proper drainage.
    • Flat roofs are not visually appealing, and won’t blend easily into a neighborhood as a traditional building with a pitched roofing system. Also, while you may have more outdoor living space, but there is usually is no room for a loft or attic.

    Flat Roofing Cost

    The cost will vary depending on the type. There are different types of flat roofing systems and each type has some benefits that can be used for a specific type of construction. While some of them are good for residential construction, others are considered more effective for commercial buildings. A few types can be effective for both. Therefore, it is important to understand different materials and then you can inquire about the cost to know it fits your budget or not. Also, the cost might vary a little depending on the contractor.

    For PVC type, you might need to spend between $200 and $700 per square. For the Modified Bitumen, it will be somewhere between $200 and $500 per square. For the Built-up Roofing, the expected cost is $200 and $700 per square. This is the average cost and you might need to spend more or less depending on your location and contractor.

    Some other factors can contribute to the end cost. For example, if you want an extra layer to make your roof more energy-efficient, you might need to spend a little more. Similarly, roof sealants, extra underlayment, and old roof removal costs can affect your budget.
