TPO Invention and How It Changed Roofing Industry in Chicago
TPO was invented in the 1980s. The membrane was first called FPO (Flexible Polyolefin). In the 1990s, it entered the US market. TPO was positively tested in commercial roofing. The most valuable features of the material are durability, heat and UV resistance and energy savings. TPO is lighter and simpler to install than many other roofing products. So, it is a more cost-effective option for large-scale commercial projects. Today, TPO is used for more than 40% of all commercial roofing installations in the US. Building owners and contractors in Chicago and Chicago suburbs value its long service life and affordable price.
TPO Roofing Solution – The Details of Its Technology
TPO roofing system is made up of polypropylene and ethylene-propylene rubber, which makes the membrane flexible and durable. Reinforced TPO also contains stabilizers and UV-resistant additives. These help the membrane work well in different weather conditions. Its key features are:
- Seam welding. TPO membranes have heat-welded seams. This finishing creates a watertight bond that is much stronger compared to traditional systems that use adhesives.
- UV resistance. The material blocks UV radiation, and even excessive sunlight cannot degrade it.
- Recyclability. TPO is an eco-friendly roofing solution, as it is fully recyclable.
These characteristics make TPO a popular and practical roofing material for commercial facilities in the Chicago suburbs.

A TPO Membrane Roof - Components and Installation
TPO is one of the best flat roofing materials available on the market today. If you are considering TPO for your new roofing in Chicago’s neighborhoods, you must know more about its structure and use cases.
Components of a TPO Flat Roof Membrane
A TPO flat roofing system is made of several layers:
- Top layer. This is the visible layer of the roof, which is made of a TPO membrane. It protects the roof from the elements like rain, snow, and UV rays.
- Insulation. A layer of additional insulation is added to improve the energy efficiency of the building. The insulation board regulates the temperature inside the building.
- Cover board. This layer provides a smooth surface to which the TPO membrane can adhere. It also adds additional strength to the roof.
- Vapor barrier. It is installed to prevent moisture from damaging the roof and the building structure in the entire Chicago area.
- Adhesive and fasteners. These are used to secure the various layers of the roof to the building structure.
TPO Roofing Installation – The Details of the Process
You can use several methods of TPO installation. They are:
- Mechanically attached TPO system. This approach secures the TPO membrane to the roof deck with screws and plates. The membrane is simply laid out and fastened to the roof. This method is easy and saves on adhesive costs. Besides, it is easy to repair when needed. It is best for flat roofs or low slope areas with moderate wind exposure.
- Fully adhered TPO system. In this case, the TPO sheets are glued to the roof surface. Adhesives are spread across the roof deck, and the membrane is pressed into place. This installation method withstands strong winds. Adhesion creates a tight fit, and it is perfect for roofs with a bigger curve or unique designs.
- Ballasted TPO system. This is a simple installation process where the TPO membrane is held in place by heavy materials like stones or pavers. The membrane is spread out and weighted down with gravel or concrete. This approach reduces damage to the roof structure during installation. If you’re looking for a roofing company close to me, this method is good for flat roofs in low-wind areas where weight isn’t an issue.
No matter what method you choose for your property in Chicago area, you must pay special attention to seam welding. Seams must be welded with hot air to ensure they’re watertight. Welded seams prevent leaks and increase the roof’s durability.
The Best TPO Roofing Applications for Flat Surfaces
TPO roofing is a smart choice for flat or low-slope roofs in commercial, industrial, and even residential buildings. It will be excellent for warehouses, offices, or retail stores because it’s durable and energy-efficient. Homeowners in Illinois with flat roofs can also benefit from TPO’s reflective surface. A white roof reflects heat instead of absorbing it, which helps keep cooling costs down during summer. It’s especially useful in areas with a lot of sun or fluctuating temperatures since TPO resists UV damage and cracking. Also, TPO may be used to install solar panels on the roof. Eco-friendly buildings choose this rubber roofing as it is fully recyclable. If you’re looking for a roofing company close to me, TPO’s benefits make it one of the top solutions in the commercial roofing industry.

Advantages and Disadvantages of TPO Flat Roof Systems
Everything You Need to Know About TPO repairs
Usually, a TPO roof remains in good condition for years. However, you cannot fully avoid repairs. What can go wrong with your cool roof?
- Punctures or tears. Small holes or rips can happen from tools, debris, or foot traffic on the roof. A heat-welded TPO patch is applied to seal the damaged area.
- Seam issues. Seams may loosen due to poor installation or exposure to weather. If you spot such a problem, it is better to re-weld the seams to restore their waterproof qualities.
- Drainage problems. Pooling water or clogged drains can lead to leaks. Drains must be regularly cleaned, especially for a low-slope roof.
- Weak fasteners or adhesive. Loose screws or peeling adhesive can make the membrane less secure. You should replace fasteners or reapply adhesive to keep the roof in place.
The best approach to repairing your TPO roof is by local professionals near you.
Pricing Considerations - TPO Roofing Costs
TPO’s cost per square foot is between $5 and $12. Several factors can influence the price:
- Membrane thickness. Thicker membranes last longer and resist damage better, but they are more expensive.
- Roof design. A simple flat roof is more affordable to install than one with lots of details like vents, skylights, or unique shapes that require more labor.
- Insulation type. Premium insulation, like polyisocyanurate, costs more but improves energy efficiency better than simple options.
However, TPO can save money in the long run – it will lower energy bills and help the environment. For the best deal, get several quotes from roof estimating services near me and compare options to find the best offer for your budget.
