What is TPO Roofing?

What is TPO roofing? It’s a type of single-ply roofing membrane used on low-slope or flat roofs. TPO stands for Thermoplastic PolyOlefin, which is the primary chemical makeup of the roof membrane. TPO is a white material that reflects heat, instead of absorbing it, making it a popular option for keeping buildings cool. 

TPO roofing costs fall between $5 and $10 per square foot, including both materials and labor. That can vary based on the size and condition of your roof, along with the insulation you’ve chosen, how it’s being installed and more. Working with a local contractor to get an estimate will give you the most accurate representation of pricing for your project. 

TPO roofing materials have two components, a bottom filler material and a top protective surface. It can be attached to the roof in a few different ways — it can be adhered, mechanically fastened or ballasted. Historically, layered material is known for developing points of weakness. Because of that, many people opt for additional fiber reinforcement to make their TPO roofs stronger. 

The downside to this method is it makes the material more rigid, which also makes it more difficult for roofing contractors to install. Instead of adding fiber reinforcement, we suggest adding an extra layer of protection using elastomeric roof coatings. TPO roofing systems have a high number of seams since the rolls come in smaller widths, but that’s what makes coatings such a smart addition — it creates a seamless layer of protection. 

The more seams a roof has, the more potential access points there are for water to seep through. TRUCO elastomeric coatings create a seamless barrier to keep water out, plus protect the TPO membranes from UV rays and other extreme weather conditions. This is an especially beneficial technique when the roof is nearing the end of its life. 

Instead of choosing a full roof replacement, choose to restore the roof with coatings — specifically, Eterna-Seal rubber roofing or NextGen Eterna-Seal rubber roofing. There’s no downtime, it’s extremely economical and it’s proven, as it has been used on roofs for 29 years. Restoring your roof with rubber coatings costs one-third that of a full replacement and can result in energy efficiencies and savings for years to come due to its highly reflective roofing material properties. Plus, it’s very easy for your commercial roofing contractor to install. 

Rubber roof coatings can prevent the TPO roofing from developing a chalky surface, plus prevent cracks and pinholes that tend to develop under constant sun exposure. When this happens and the reinforcement scrim is exposed, the membrane fails — allowing moisture to seep in. TRUCO rubber roof coatings protect the roof from sun damage, prevent these issues from forming and at the same time, resist moisture. There’s no better way to add durability and improve your roof’s life expectancy.
