In our previous blog “Is a Single Ply Membrane Roof Right for you?” we compared the three main types of single-ply roofs and their ideal environments. Today we will be diving deeper into a TPO single-ply roof, to help you determine if this type of roof is right for your business.
What are TPO roofs?
TPO roofs or Thermoplastic Polyolefin, gained popularity in the early 1990s as being a cheaper alternative to PVC style roofs. TPO is made from combining various fillers like fiberglass and ethylene propylene rubber, which creates a lightweight, reflective material that helps to lower the cost of energy.
How are TPO roofs installed?
They are usually sold in sheets of 10 and 12 feet wide. TPO membranes come in a variety of thicknesses including 45, 60, 80 mil membranes (1 mil is equal to 0.001 inches). The most popular one is 60 mil membranes (0.06 inches thick). This thicker membrane provides more protection against puncture damage, UV rays, and better resistance to severe weather like hail and high winds that cause debris. TPO roofs can be installed with a bonding adhesive or can be mechanically fastened.
Benefits of TPO Roofs
- Cost effective (about 30% less than traditional PVC)
- Energy efficient
- UV & Heat resistant
- Class A fire resistant
- Fungal resistant (no biocides are required)
- Additional color options
- Flexible (more resistant to puncture and tear damage)
- Low Maintenance
Due to the unique nature of TPO roofs being offered in multiple colors with white being the most popular, they are highly resistant to heat, and UV rays compared to traditional black roofs, which will save on energy required to keep the building cool (air conditioning).
How long do TPO roofs last?
No roof is guaranteed to last forever, however TPO roofs last an average of 15-20 years and upwards of 30 years when installed and maintained properly. That’s why having a reliable installation company like ASI is important.
At ASI we take the time to understand our customers’ needs and conduct a full evaluation of the roof or project before we create a scope of work. This due diligence allows us to assess the composition, age, and remaining life of the existing roof system, and provide immediate and long-term recommendations with an accurate timeline and estimate. We work directly with you to educate you on your options, so you have the knowledge you need to make informed, confident budgeting decisions.
