  • Build Up Roofs (BUR)

Build-up roofs are very famous and used worldwide, and they have been the most used type of flat roof for over 100 years. They are effortless to spot since they have a unique style with their textured tar and gravel exterior.

Its name comes from the installation method to build the roof up until a dense layer of tar and minerals is packed on the rooftop. What makes build-up roofs so popular is their cost and low maintenance needs. Although this is not the cheapest option, it has a reasonable price. It helps to combat UV rays as well, and it can last up to 15 – 20 years with proper care.

  • Thermoplastic Membrane Flat Roof (TPO or PVC)

Being fray or white most of the time, the thermoplastic membrane flat roof can also come in other colors. It is a single-ply layer of material fixed to the roof with plates and screws, and it lasts for many, many years. This flat roof has a high-temperature tolerance and is made of thermoplastic olefin (TPO) or polyvinyl chloride (PVC).

As many may know, PVC is very flexible, making it easier to install. Also, it is sturdier than TPO and can last up to 20 years. On the other hand, TPO is more eco-friendly, and it allows you to recycle the old material. It can also last up to 20 years.

  • Modified Bitumen Roof

The modified bitumen roof is famous as well, being an asphalt-based sheet very similar to the BUR in both appearance and texture. It is installed in five layers, being the first one insulation. The second is the modified base sheet, the third is the modified bitumen membrane, then the adhesive comes, and the surfacing topcoat is installed.

Therefore, this is a very long and labor-intensive process that must be made by a professional. Yet, it is worth it since the roof is easy to repair and can last two decades.
