Flat Roofing Options: TPO Roofing vs. Torch Down Roofing
So it’s time to replace your flat roof. The previous roof installment looked old even before you purchased the property, so you’re aware that a replacement is long overdue.
When it comes to flat roofing options, however, you have no idea where to begin.
Let’s go over two popular types of flat roofs – TPO Roofs and torch down roofs – and explain their benefits and differences.
TPO Roofing Style
The term “TPO” is short for Thermoplastic Polyolefin, which is the material that makes TPO roofing.
TPO roofing consists of a single-ply membrane made up of this synthetic material and reinforcing scrim. It is quickly becoming one of the most popular flat roofing options for residential and commercial buildings.
TPO roofing is great at reflecting the sun’s UV rays away from the building, which helps cut down on cooling costs in the summer.
The first step to installing a TPO roof is to remove the previous roofing material and lay down insulation for the base layer.
Next, the TPO roofing material is attached mechanically, or with an adhesive, to the insulation layer.
Finally, the seams of the roof are welded together using a hot-air gun.
Advantages of TPO Roofing
TPO-style roofing can last up to 30 years if taken care of properly. Additionally, TPO roofing gives you the option to decide what kind of insulation layer goes under the main membrane.
TPO roofing not only helps cut the cost of cooling your building, but also proves to be flame-resistant, as it proudly holds a Class A Fire-Resistant rating.
Torch Down Roofing
Torch down, or “Torch on roofing,” has a bit of an installation process than TPO. Sheets of modified bitumen are applied to your roof using a propane torch.
There are two types of torch down roofing: two-layer systems and three-layer systems.
Both types include a cap sheet that helps seal up the roof, but the three-layer type includes a base sheet for added insulation and protection.
Advantages of Torch Down Roofing
Upon completed installation of a torch down roof, water resistance will be readily noticeable. Torch-down roofs are often effective in all types of climate.
Finally, much like TPO roofs, Torch down roofs can last up to three decades and reflect the sun’s UV rays away from your building.
