What Are the Different Types of Flat Roofs?

Are you looking for a new roofing system for your commercial property? Is your roofing system low-sloped? You might consider a flat roof. Flat roofs are roofing system that have a pitch of less than three inches or 12 inches. Many people who have a low-sloped roof tend to ask, “What is the best material for a flat roof?” It is honestly going to depend on what you are looking for. When considering a new roof, you need to think about how long the roofing system is going to last, how much is the particular roofing material, will the roof withstand severe weather, is it durable, and will it fit the aesthetic of your building. Knowing more about different flat roof options will help you make a better decision for your building. Here are some of the most common flat roof ideas.

  • Built Up Roofing: Built up roofing or BUR is a roofing system that is manufactured with several layers of fabric and bitumen, then layered with tar or gravel on top. Its low maintenance can resist severe weather, UV rays, and water. This roof can take a long time to install, is pretty heavy, and can be damaged by wind and moisture.
  • EPDM Roofing: This is a rubber roofing membrane that is made of ethylene propylene diene terpolymer. People love this type of flat roof not only because it’s durable, but because it’s one of the most affordable commercial roofs on the market. It is also very lightweight, doesn’t develop leaks, and its UV resistant. A disadvantage is that it can puncture easily.
  • Modified Bitumen: Modified bitumen is another type of asphalt roofing similar to built up roofing, but it has cap sheets that use polymers for more durability. They are easy to install and can be installed in a variety of ways. They are also affordable and require little maintenance. If they aren’t correctly installed, they can form roof leaks.
  • PVC Roofing: PVC or polyvinyl chloride is a single ply roof that is very eco-friendly, flexible, flame resistant, and lightweight. It is also a pretty long-lasting roofing system. The biggest issue that people find with this flat roof is that is costs a lot.
  • TPO Roofing: TPO roofing is a single ply roofing system that is made of polypropylene and ethylene-propylene rubber. The color is usually white, which means that it reflects UV rays and keeps buildings cooler. Not only is it affordable and easy to install, but it is chemical resistant. It doesn’t have a high heat load and many question how long it actually lasts.

Flat Roof Vs Pitched Roof

If you are building a new commercial property, you might be wondering if you should go with a flat roof or pitched roof. What are the differences and which one is better? Flat roofing is easier to install because it is a completely flat surface, and they are more cost-effective, so they can save property owners money. Because of the materials that can be used like EPDM, PVC, TPO, they can reduce UV damage and energy bills. Because of the flat surfaces, flat roofs are easy to maintain and repair because roofers can easily walk on top of them. They are also a great place to install HVAC units, as well as storage spaces. The issues that you will see with flat roofs is that they can suffer from bad drainage, which is why drains are really important.

Unlike flat roofs, pitched roofs don’t have to worry about drainage issues because water will just flow right off the roof. Because there is no worry for water buildup, property owners don’t have to worry about mold or debris running the roof. This makes it so much easier to maintain and repair the roof. However, because pitched roofs can be pretty steep, more safety needs to be taken into consideration and it can cost longer to repair, maintain, or even install this type of roof. All in all, deciding between a flat roof or pitched roof is going to depend on your personal preference.

How Do I Know If My Flat Roof Needs Replacing?

Lots of people want to know when a flat roof needs to be replaced and the answer is if there are is a lot of pooling water, there are tears and rips, has other extensive damage, or it’s past its lifespan. Many people ask, “How long do flat roofs last?” and it depends on the roof material, but they can last anywhere from 10 to 25 years. Sometimes if the roof damage isn’t too horrible, your roof might qualify for a flat roof coating instead of a complete roof replacement.
