Is TPO roofing good?

When you have a commercial building with a flat roof, among all the roofing options you have available, TPO roofing is among the best. This single-ply roofing membrane is durable, energy efficient, and cost-effective. In other words, with TPO, you’ll save money while getting a tough, long-lasting roof. These roofs often cost much less to install than similar membranes like PVC or EPDM and are valued for their ability to reflect sunlight, especially harmful UV rays. This will help keep your building cooler and improve its overall energy efficiency year-round. You will also save money on repairs and maintenance. They resist dirt, bacteria, algae and debris build-up which can damage the roof and they are highly puncture- and tear-resistant.

What is TPO made of?

TPO roofing is a single-ply rubber membrane composed of Thermoplastic Polyolefin. This material is combined with fabric reinforcement to stabilize and strengthen the membrane. These membranes are usually manufactured in sheets of 10, 12, or 20 feet. 

Is TPO better than EPDM?

Two rubber roofing systems are commonly used for flat roofs today, either TPO roofing or EPDM roofing. While both are similar, especially in that they are single-ply membranes that are relatively easy to install, many people are choosing TPO over EPDM as a preferred roofing material. If you are thinking about choosing between the two materials, below lists some of the advantages and disadvantages of each.

  • While both are energy efficient, because EPDM is darker it’s less efficient in the summer, causing cooling systems to work overtime.  
  • TPO is three times more puncture-resistant than EDPM, although EPDM holds up better against certain types of impacts like those from hailstones.
  • EPDM is easier to repair, requiring no electrical sources. TPO is welded, so an electrical source must be available to make most repairs.
  • TPO lasts on average about 15-20 years while EPDM can last about 25-30 years.

Location and weather are two primary factors that normally determine which system is best. TPO is generally good for temperate or even hot climates where hail isn’t common, while EPDM is better for cooler climates or where hail is a problem.

What is the difference between TPO and PVC roofing?

TPO roofing and PVC roofing are often confused, largely because the material looks similar, as both are normally either white or lighter colors like tan. Both are also composed of similar synthetic polymers, though you may know PVC better as vinyl. PVC is also used in plumbing pipes and similar uses. When used in roofing, both are also single-ply membranes. TPO has been in use since the 1990s, so it is a relatively new roofing material and continually researched and improved upon. PVC has been around since the 1960s and many consider it more stable than TPO, because of the longevity on the marketplace. TPO tends to cost less to install initially, although under ideal conditions it may at best last about 20 years, while PVC can last much longer.    

What is the life expectancy of a TPO roof?

Under ideal circumstances TPO roofing will last about 20 years, although some newer improved TPO materials can last 20-30 years. Many manufacturers will offer warranties up to about 25 years. Typically, however, TPO is good for about 15 years.

Is TPO roofing fire resistant

TPO on its own, like some other single-ply rubber roofing membranes, is not fire resistant. Chemical fire retardants, however, can be added during the manufacturing process to this type of roof to give it a Class A fire resistance rating. The Class A rating is the top rating the Underwriters Laboratory gives to fire-resistant materials. If a fire does occur on this type of material it will have a lower flame spread so it can withstand a fire much longer than lower-rated materials.

Can TPO roofing be painted

TPO roofing can be painted. That said, the roof normally needs to be treated before it is painted. There are some paint manufacturers, however, now producing paint that will directly adhere to the material without treatment. 

How is TPO roofing installed

TPO roofing is fairly easily installed. Once the old roof is torn off, new insulation is installed first, then the cover board comes next. The membrane is rolled out and either attached with an adhesive or mechanically attached. Seams are then sealed with a hot air weld.
