TPO Flat Roof Repair and Replacement
TPO stands for Thermoplastic polyolefin, which is currently the fastest-growing segment of the entire commercial roofing industry. TPO is part of a broad family of rubber roofing materials. TPO is a blend of polypropylene and ethylene-propylene rubber. TPO consist of a single ply of thermoplastic polyolefin membrane which is composed of three layers; a polymer base layer, a polyester-reinforced fabric center layer, and a thermoplastic polyolefin top layer.
TPO roof systems have been installed all across the U.S. for the last 30 years. According to the 2014-2015 National Roofing Contractors Association (NRCA) Market Study, most new projects in the past few years have specified a white TPO roof. In general, TPO is a relatively low-cost, high performing roof membrane when installed correctly.
The TPO membrane comes in rolls of different sizes, making it suitable for a variety of flat roof projects. TPO membranes are made with a co-polymerized rubber that allows them greater flexibility, which is a great advantage to buildings that have to endure our cold Minnesota winters without leaking. Two other advantages of TPO roofing are that TPO is as UV and heat-resistant as EPDM roofing, plus TPO roofing is as heat-weldable as PVC roofing.

Commercial TPO Roofing Installation Costs
TPO Cost: The total cost on an average roof is between $11 and $16 per square foot as well. A typical assembly includes the same basic elements as the EPDM roof, with similar attachment methods, except ballasted with river rock, but the roof membrane is typically welded together at the seams, but they can use pressure sensitive tapes in lieu of the welded seams. Advantages to this membrane are standard pre-finished or TPO coated sheet metal flashing can be used at the perimeter edge of the roof assembly (attached to the membrane) and the membrane is considered to be monolithic (one piece) if all the seams are welded together.
A monolithic roof membrane offers a great advantage, because when the entire surface of the membrane is welded together, there is less opportunity for seam failures than with primed and taped seams. TPO membranes come in several different colors; some lighter colors reflect sunlight and are candidates for rebates from the local energy companies. The disadvantages are TPO coated sheet metal cost two to three times what standard prefinished sheet metal cost and without a hail protection board (we install this unless specified otherwise); the membrane is susceptible to hail damage.

Most Popular FAQ’s
What is TPO roofing?
TPO (Thermoplastic Polyolefin) roofing is a single-ply roofing membrane used for commercial buildings, known for its energy efficiency and durability. It is highly resistant to UV radiation, chemicals, and punctures, making it ideal for flat and low-slope roofs. TPO roofing is also an environmentally friendly choice due to its reflective surface, which helps reduce cooling costs.
What is the cost of TPO roof installation?
The cost of TPO roof installation depends on the size of the building, the specific requirements of the project, and any special features needed.
