TPO Commercial Roof Systems-Tunkhannock

Thermoplastic Polyolefin or TPO roofing is a single-ply roofing membrane consisting of synthetic components with a fabric reinforcing scrim. It is usually composed of a mix of polypropylene and ethylene-propylene rubber. These are popular commercial roofing applications that make up about 40% in the roofing market.


The substrate is first cleaned or removed. Insulation is prepared afterwards. Several selections are polyisocyanurate, expanded polystyrene, and extruded polystyrene. The TPO can be adhered to the cover board chemically or mechanically. The rolled membrane is hot air weld to improve cohesion.

Advantages of TPO

Single-ply membrane roofing does not include insulation which gives the customer flexibility in choosing their preferred insulation material.

TPO membranes can be mixed with fire retardant chemicals to perform as a Class A fire resistance roofing membrane. It has high reflectivity which gives roofs excellent UV ray protection. The layer of TPO membrane is bright white. This decreases the heat of the building which effectively reduces the air conditioning costs a commercial building might need for example, especially during extreme weather conditions.

Disadvantages of TPO

Compounds that are added on top of the TPO roofing can decrease the durability of the material. For example, laminating processes can cause cracking and splitting in the surface of the TPO.

TPO are usually small in the width which would produce seams in conjunctions. Water can get in these seams and will also make the membrane prone to expansion from heat. However, careful installation by professionals can prevent this from happening. The right choice of manufacturer also plays a big role in installation.

When and How to Repair the TPO

The average durability of TPO is 15-20 years. You will know that your TPO needs a commercial roof repair when it encounters any of the following

  • Water leakage in the building
  • Ripped seams (or close to it)
  • Punctured TPO membrane

If you have any of these problems, it’s best to contact professional roofing contractors right away to prevent any further damage to your roof and your building. A professional will conduct an inspection of all problems in your roofing as well as the condition for your TPO membrane.

For TPO membranes that are diagnosed for repair, the damaged or saturated parts will be replaced. The substrate will be cleaned as in installation. The seams of the TPO layer will be fortified by the professional especially on areas deemed more vulnerable to damage.

If the condition of the seams are beyond repair, a new cover board may be installed over the TPO roof. You can opt to go for a spray foam roofing system that will keep you from having to remove the whole existing roof or adding another TPO layer.

TPO roofing is the most popular roofing solution because of its durability and cost-effectiveness. It is straightforward and viable for most infrastructures.
