Different Types of Flat Roofing

There are six major types of flat roofs that we install and replace including metal, EPDM, TPO, PVC, built-up, and modified bitumen.

  • Metal flat roofs: These are the most common and are typically made out of aluminum, which is exceptionally durable. This material lasts more than thirty years and reflects heat, making it an energy efficient option. As for downsides, you won’t be able to install any other kind of roofing on top of metal flat roofs as you could with asphalt shingles, for example. So, in the case of a renovation, the entire roof would need to be demolished and replaced.
  • EPDM: Also called, ethylene propylene diene monomer, flat roofs are just a fancy way to say that these roofs are made from a synthetic blend of rubber. Most often used for large office spaces, it’s a durable and affordable option for flat roofing. EPMD flat roofs are easy to install, but they’re also prone to leakages. So, it’s important that the flat roof installation company make sure the seams are sprayed with a protective sealant. These coatings will add cost but are well worth it to prevent water damage.
  • TPO Roofing: Thermoplastic Polyolefin (TPO) roofing is a popular roofing material, especially for flat or low-slope commercial buildings. TPO is prized for its energy-efficient properties, as its white reflective surface significantly reduces heat absorption, leading to lower cooling costs. This single-ply roofing membrane is made from a blend of polypropylene and ethylene-propylene rubber, offering remarkable durability and flexibility. TPO roofing is resistant to ultraviolet rays, ozone, and chemical exposure, making it an excellent choice for areas that experience extreme weather conditions. Its installation involves heat-welding seams, which provides a strong, watertight bond, enhancing the roof’s resistance to leaks and wind uplift. Additionally, TPO is an eco-friendly option, as it is 100% recyclable and does not contain chlorine, a feature that distinguishes it from other thermoplastic membranes.
  • PVC Roofing: Polyvinyl Chloride (PVC) roofing is another highly regarded single-ply roofing solution, especially suited for commercial and industrial buildings with flat or sloping roofs. PVC roofs are known for their strength and long-term durability, with a typical lifespan exceeding 20 years. One of the key features of PVC roofing is its chemical resistance, making it an ideal choice for buildings that emit oils or other chemicals, such as restaurants. The material is also fire-resistant and can self-extinguish, which adds an extra layer of safety. PVC roofs are also highly resistant to water, wind, and fire, and can withstand harsh environmental conditions. The material’s flexibility makes it easy to install around roof penetrations and on irregularly shaped roofs. PVC roofing is also environmentally friendly, as it is recyclable and often includes a high proportion of recycled content. This type of roofing is available in a variety of colors, but like TPO, its reflective properties can significantly reduce energy costs by maintaining cooler roof temperatures.
  • Built-up flat roofs: BUR roofs are a mixture of tar and gravel. This option has become popular because they’re aesthetically pleasing, they make your home more energy efficient, and they are quite durable thanks to the many layers. There are some downsides though. The layers of built-up flat roofing can make it very heavy, so your home will need a thorough evaluation to be sure the structure can bear the weight. Plus, the installation process creates a hazardous area so you won’t be able to live in your house during the renovation.
  • Modified bitumen: Flat roofs are an affordable option but aren’t often used due to their delicate installation process. Because this flat roofing is secured using a blowtorch, it’s imperative that only seasoned flat roofing company do the installation. For most people, the dangers outweigh this flat roof cost but, if you’re willing to go for it, it’s a great budget-friendly option.

We specialize in various commercial roofing systems from single-ply membranes, flat roofing to multi-family roofing systems.

Reasons to Install Flat Roofing

One of the main reasons people opt for flat roofing even though it’s not very common is because of just that – it’s not very common. You’ve probably seen celebrity-designed homes with modern floor to ceiling windows and a sleek flat rooftop. Those are the types of unique properties that will benefit from a durable flat roof.

Another reason people might choose flat roofing is that it’s energy efficient. Due to their large surface area, they’re an excellent option for those wishing to capture solar energy to power their home, and many of these roofing options reflect heat to keep your energy costs low.

As with anything, there will be downsides, and flat roofs are no different. Since there’s no slope on these roofs for water to run off of after a storm, for example, it’s common for flat roofs to have water build-up in one area or another. Plus, they’re usually made of a more porous material than say a clay roof tile, making them even more susceptible to water damage.
