Here are the benefits:

  • Non-Flammable


This roofing material is resistant to fires and flames. The material by which it is made from makes it harder for it to catch a flame. Since they are harder to burn, there is no combustion. Your roof won’t burn down easily and no harmful toxins would be released.

  • Flexibility

This roof would be very flexible. That means you can easily customize it to get the aesthetic you want for your house. Moreover, this customization even allows you to lower the amount of waste and rubble that is created during the installation of the roof.

  • Light-weight

You could even put a new PVC roof on top of an existing one. You wouldn’t have to tear the old roof off which means no unnecessary waste would be added into the landfill.

  • Low Chances of Leakage

The PVC membranes have a special quality about them. They are heat-weldable. This gives the ability to have highly strong and dependable seams. As a result, there is little to no leakage found in the PVC roofing systems. In the long run, this is a great option because no dampness, moisture or mildew would be present in the house’s roof.

  • Highly Reflective

  • Long Lasting

The materials are strong enough that they could last you for a long time. For instance, if a building is around for let’s say a hundred years, then it only needs to get the PVC roof replaced 3-4 times. If it is not a PVC roof, then it has to be replaced 8-10 times almost!

  • Recyclable

Along with there being no waste, PVC roofing systems are quite recyclable. You can easily recycle and reuse the PVC membranes in the roof.

Of course, the PVC membranes are not the only choice you have. There is the built-up roof, modified bitumen, rubber membrane and TPO.

Let’s take a look at each one.

  • Built-up roof (BUR)

Built-up roof

This is one of the cheapest options you can get if you are considering a flat roof. But this has a lot of drawbacks that you should know about. For starters, they are very heavy. This can add a lot of weight and stress to the foundation of your house. Moreover, they are not fit for all kinds of houses because the material they are built with doesn’t easily complement all kinds of properties. It is hard to install so make sure you are hiring professional Flat Roof Installation Services in Seattle WA to get the job done.

  • Modified Bitumen

This type uses just one single layer. The layer is made of an adhesive roofing material. These things make it easier for you to install a roof yourself, if you are interested in doing that. Plus, another good thing about this type if that it can reflect the sun’s infrared energy at times. As a result, this would make the property less hot and reduce your AC costs ultimately. The only major problem with this is that the torch-down system of modified bitumen is not fire-resistant. It also breaks down much faster due to wear and tear compared to other types of roofs.

  • Rubber Membrane

The rubber membrane type was really popular because it was easy to fix any leaks or cracks in it. The repair costs were usually quite affordable. Moreover, they are also lightweight and won’t burden your house’s foundation. These materials are also recyclable, just like the PVC membranes. It also looks beautiful with its black color. Though, the black colors usually make it absorb more heat and make your house warmer in summers.
