What are the Advantages & Disadvantages of a TPO Roofing?

One of the fastest growing surfaces for flat surfaces, especially incommercial buildings, is TPO Roofing. These thin and inexpensive roofing materials are popular among building owners who want to have a solid roof and reflector that does not break the bank.

What is TPO Roof?

TPO stands for thermoplastic polyolefin, a monolayer roofing membrane covering the surface of the surface. The name is somewhat misleading because instead of being plastic, the TPO is actually one of the different types of rubber, usually a combination of polypropylene and ethylene - propylene.

Benefits of Roofing TPO

The positive cost is greater in installing the roofing TPO on the flat roof. TPO is one of the cheapest materials on the market today, at a lower cost than EPDM or other types of rolled rubber roofing. The other big positive to use TPO is its color. This type of roof is white on the top, which helps to reverse the sunlight and stop the accumulation of heat inside the building.

Other positives include the fact that you have options on how to install it; it can be mounted with adhesive or installed directly on the roof. They can also be welded to heat in places around chimneys and other protrusions. Finally, the TPO resists corrosion and collapses when many materials are touched. It also discourages the growth of fungi or algae and does not require pressure washing.

Disadvantages of TPO

Unfortunately for those looking at roofing the TPO, the list of negatives far outweighs the pros. While it is inexpensive and white, various manufacturers of TPO products can manufacture significantly different products. This means that you may get a good roof quality from a manufacturer, but at the same price, you can find one of the buildings that were built very badly from the other. Added to this confusion is the fact that the material comes in a wide range of different thicknesses. Some buyers may mistakenly believe that thick materials are of better quality and will last longer. Unfortunately, this is not the case; thickness has little to do with the durability of this material, all worn at roughly the same rate. TPOs have changed in recent years, so it is impossible to determine how long the current ceilings will last, but the overall estimate puts the TPO ceiling between 10 and 20 years.

This is partly due to the fact that the top layer of the material is laminated. Packaging of any substance is a weak point that can cause the material to shrink, break, recruit and deteriorate over time. In fact, it is common for some cheaper TPO surfaces to develop cracks in the surface relatively quickly.

In addition, the lists that have a TPO are relatively small and display hand. So, even though you may buy one hundred feet of material, it is likely that you get layers every 6 - 8 feet. These seams can mean a potential place for membrane expansion and contraction, which may eventually lead to the preceding layers and infiltration of water to the surface.

Choose the TPO

If you choose to buy a TPO cap, put your search in the manufacturer to find one that has a warranty or a track record that can be delayed over time. For more info Read More Please.
