What Is TPO Roofing?
The TPO roofing membrane was initially used as a more economical and efficient alternative in the roofing market. Typically, TPO roofing material is made from a mixture of polypropylene as well as ethylene-propylene rubber.
These roofing membranes come in different thicknesses depending on the commercial or residential building roof application. Roofing sheets of TPO roofing can be obtained in 45 mils, 60 mils and 90 mil thickness as required. But it has the most commonly used normal thickness of 60 mils.
It was considered appropriate to use TPO roofing instead of PVC roofing products. TPO roofing is used as a single-ply roofing system. A thermoplastic polyolefin membrane is used to form this layer. The membrane is composed of three layers:
- TPO polymer base.
- Polyester-Reinforced Fabric Centre.
- Thermoplastic Polyolefin Compounded Top Ply.
A variety of building materials are commonly used as filler material in TPO production. These include fibreglass, carbon fibre, talc, wollastonite, metal oxy sulfate, ethylene-propylene rubber in rubber and EPDM.
TPO sheet for TPO roofing system is usually available in the market 10, 12 or 20 feet wide sheets. These sheets are rolled up and taken for commercial roofing.

2. Compression Due to Heat:
This type of roofing shrinks due to constant exposure to heat. As a result, the seam fails to crack and the adhesive is removed. Due to the external environment, if not treated in time, your flat roof can be severely deformed.
No reliable material can avoid UV rays. If the roof is torn or punctured, UV rays penetrate the adhesive layer. This reduces the energy efficiency of the roof.
3. Poor TPO Installation:
Without proper installation, single-ply membranes can cause problems in the TPO roofing system. Failure to cut the appropriate seam size for the roof results in gaps in the TPO membrane. The result can be damaged by wind and water.
In addition, improperly welded seams loosen during the first tho cycle. Which invites material failure and water infiltration.
4. Adhesive Deteriorates:
UV rays and sun heat make the adhesive for roofing less energy efficient. TPO seals the seams of the adhesive membrane together in single-ply membrane roofing and provides protection to the roof. UV rays and sun heat expose the adhesive board to the roofing material and cause water problems with TPO roofing.
The most common problem with TPO roofing is that it does not last as long as other roofing systems. In the roofing industry, this type of roofing is definitely considered strong and durable.
Manufacturers strive to find this type of roofing material more affordable and durable. This is what it means. Like other types of roofing systems, it can have material failures and cracks in the seams.
TPO Roofing Installation:
The first step for TPO roofing is to prepare the substrate. TPO over an existing roof, solutions are usually removed. Once the substrate is ready you can help with the energy efficiency of your building
Insulation is installed from many different options.
Expanded polystyrene has a higher R-value than any other insulation currently available on the market. This insulation can be used to insulate floors, ceilings and walls. EPS insulation occurs as durable material. It can also be easily used for ground contact applications.
Polyiso roof insulation installation is the most commonly used type of insulation in the market. This type of insulation is more expensive than other options available. Its use, however, helps to obtain a high R-value, even with additional costs.
After the installation of insulation for the roof, the TPO roofing membrane can be installed on the cover board by bonding adhesive in a mechanically constructed roof system. After rolling out the TPO roofing membrane, the contractor will use a heat gun to weld the seams of the roof together. Which is usually a very fast and effective method.
R-value indicates the ability of the material to resist the flow of heat. Roofing and other building techniques generally require high R-rating insulation. Which helps maintain the building temperature.
