What is a TPO roof?
TPO or Thermoplastic Polyolefin is a single-ply membrane composed of polypropylene and ethylene-propylene rubber. For installation, the membrane is either mechanically fastened or fixed with an adhesive that bonds to the cover board. After that, the seams are welded together with a hot-air gun. It’s most commonly used for flat roofs and gives the property a modern, minimalist look.
Is it a good choice for residences?
Although TPO is most commonly associated with commercial properties, it has many advantages that make it ideal for residential properties as well.
- Durable: TPO protects your roof from dirt, bacteria, algae, and debris build-up, while the membrane’s flexibility makes it highly resistant to tears, punctures, and impact damage. The hot-air welded seams are even stronger than the EPDM adhesive and tape seams!
- Energy-efficient: These Energy star rated roofs are heat-reflective and can withstand even damaging ultraviolet, ozone, and chemical exposure. Because of this, it’s considered a cool roof and can keep your interior temperatures comfortable during those hot summer months. Not to say, you’ll save a lot of money that you’ll otherwise spend on air conditioning.
- Fire-resistant: TPO membranes are Class A fire-resistant. This is because the manufacturer adds fire-retardant chemicals to the composition of the material during the production process.
- Longevity: With proper installation and maintenance, these roofs can last 10-20 years. During this time, you’ll not be spending much money because the roofs are highly durable and easy to install. Overall it’s an inexpensive yet cost-effective roof to invest in.
Usually, the cost-effectiveness gets people to invest in a TPO roof quickly. But it is wise to note that the TPO quality highly varies among manufacturers. So make sure you do your research before getting started.
