Are TPO Roofs Good?
Quality protection with TPO
If you aren’t familiar with commercial roofing, you probably aren’t familiar with a TPO roof. So, what TPO means? This is a single ply roofing membrane material common on commercial structures. TPO stands for Thermoplastic Polyolefin that is made with a single layer of synthetics with reinforcing scrim to strengthen it for flat commercial roofs. To the unknowing person, what you see when you see a TPO roof is a white roof top.
A TPO roof is installed either ballasted, chemically adhered, or mechanically fastened to the roof’s insulation adding a protective layer to the roof. A well-known roofing material in for commercial roofing that is available in different types, adjusting to the company’s budget and the needs of the facility housed in the building.
The two main types of single-ply membrane roofing is the TPO (Thermoplastic Polyolefin) we’re discussing in this article, and EPDM (Ethylene Propylene Diene Terpolymer). One isn’t specifically better than the other, because both have their own chemical makeup that makes them energy efficient as well as offer other benefits.
When it comes to tpo roof, what is it that makes it the better choice? For a commercial structure with a flat roof, TPO roof’s white reflective color is ideal for regions that have hot summers, like in Maryland, New Jersey and Virginia. The reflective properties of the bright white roof installation is ideal in reflecting the UV rays and heat away from the building. A TPO roof is a money saver for the owner of the building during the summer because the air conditioning doesn’t have to work as hard to cool the building.
Does TPO have an R value?
A tpo roof with insulation in typical installation has an R-value of 0.24-0.33, as does the EPDM single ply roofing. If this typical installed thickness isn’t sufficient enough for the customer’s request, like R-30 value, another layer of insulation will need to be added before the TPO roof is installed. A commercial structure in a colder climate may not benefit from a TPO roof as a commercial structure in the warmer region.
Is TPO waterproof?
A Thermoplastic Polyolefin roofing is a polymer single-ply membrane type that is installed using thermo-welding to connect the seams. This type of roofing membrane has been used since the 1980’s and is still in use, even considered to be a growing membrane trend for commercial roofing because of the waterproofing benefits it brings to the table.
In addition to TPO roof being waterproof, adequate, proper, working drainage is necessary as well. As the roofing contractor begins the installation, they will check the drainage system in place and make any recommendations for improvement if necessary.
What is the life expectancy of a TPO roof?
In addition to all the TPO roof benefits that include the waterproofing, a TPO roof that is installed properly by a professional and reputable commercial roofing contractor, and proper routine maintenance, can last up to thirty years. With a steel decking that measures between 18 and 22 gauge steel, the application of TPO roofing material to this deck contributes to the longevity.
Several factors contribute to TPO roof lifespan, and with roofing technology always expanding, we’ll likely see TPO roofing last up to 50 years or longer in the near future. A TPO roof, or any single ply roofing membrane lifespan is dependent on several factors, the main ones being:
- The Climate
- Quality Installation
- The System Type
- The Roof penetration
- Ongoing Proper Maintenance
Choosing an installer that is experienced in TPO roof installation is just as important as making the right choice in the membrane type.
How do you maintain a TPO roof?
As you search for “tpo roof installers near me” on the internet, you’ll want one that will take the time to discuss TPO roof care and maintenance too. Most of a TPO roof cleaning is done with a cleaning solution. a pressure washer and a soft bristled brush with a long handle. You shouldn’t do any cleaning until after taking the steps to protect any areas that water could enter, like base flashings and low curbs. You’ll want to protect the exterior of the building and any foliage around the structure as well.
The benefits of a TPO roof that we have mentioned is the longevity and the reflectiveness. Other benefits a TPO roof offers include:
- Fire resistance
- Chemical resistance
- Mold resistance
- Puncture and tear resistance
One of the biggest benefit of TPO roof that makes it one of the most popular is the installation cost. It is one of the least expensive roofing materials to have installed, something that commercial structure owners desire.
By choosing a quality contractor with strong reputation and keeping the maintenance and upkeep as recommended, getting repairs made as soon as the need is discovered, a TPO roof will be an investment that will serve you well for many years.
