3 Options For Your Flat Commercial Roof Replacement

If you have a flat commercial roof and you are getting ready to replace your commercial roof, it is important to know your options. When it comes to commercial flat roofs, there are multiple options you can choose from. The key is to find the roofing material that works the best on your roof and with your budget.

Option #1: Built-Up Roofing

One of the most popular flat roofing materials is a built-up roof, often referred to as BUR. It is a popular roofing option because it is inexpensive. When running a commercial building, you have a lot of expenses, and being able to save on your roofing costs can be excellent.

Next, BUR roofs are made out of various layers. The use of multiple layers helps create a very insulated roof, which can help you save on your commercial energy costs. Additionally, a BUR roof, with its gravel topcoat, is a visually appealing flat roof option.

With a BUR roof, you will have to vacate the building during the installation process. You also need to have reinforced joists holding up your roof, as a BUR roof is on the heavy side. Reinforcing the joists, and vacating the building during the installation process, can increase the overall cost of installing a BUR roof.

Option #2: Modified Bitumen

Another option for a flat commercial roof is modified bitumen. This is a single-ply roofing system that is rolled onto your roof. Older styles of modified bitumen had to be applied using a blowtorch; nowadays, though, almost all modified bitumen roofing material can be installed by sampling, peeling a covering off the backside, and adhering the material to your roof. A modified bitumen roof doesn't stand up well to scuffing and tearing and isn't great for any commercial roof that has a lot of foot traffic.

Option #3: PVC

PVC is a really popular roofing option. However, it is applied in rolls and does have some seams, which does present a vulnerability. The seams, though, are sealed up using heat welding, helping to make the bond between each sheet much stronger than a simple adhesive.

PVC is often considered one of the best flat roof materials, as it is easy to install and very durable. It also does a great job of reflecting heat away from the building, helping to increase the energy efficiency of your building. Additionally, PVC roofs don't easily allow water to pool on the roof and degrade the material.

When it comes to putting a new flat roof on your commercial building, there are lots of materials you can choose from. For example, you can use PVC, modified bitumen, or built-up roofing on your building. Talk to your commercial/industrial roofing contractor to determine the best material for your building.
