TPO Roof Installation in Metro Detroit

TPO roofing is a white, single-ply membrane with heat-welded seams that is used on flat and low-slope commercial roofs. T&M Roofing installs, repairs and maintains TPO roofs for offices, retail stores, warehouses and industrial buildings in Detroit and across Metro Detroit, with free written quotes. Call (313) 600-4538.

What Is TPO Roofing and Where Does It Fit?

TPO (thermoplastic polyolefin) is one of the most common membranes on commercial roofs. It comes in wide rolls that are fastened or adhered to the roof and then joined with hot-air welding. A white TPO surface reflects sunlight, which helps keep the building cooler in summer, and the membrane resists punctures and many chemicals.

We install TPO on flat and low-slope roofs on offices, retail spaces, warehouses, factories and other commercial buildings. It is part of our wider commercial roofing in Detroit, alongside EPDM and Duro-Last systems.

How We Install a TPO Roof

Every TPO roof is built to the membrane manufacturer’s requirements. The details we cover in your written scope:

• Attachment method. TPO can be mechanically fastened, fully adhered or attached with induction-welded plates. The right choice depends on the deck, the existing roof and the wind requirements for the building.
• Insulation and cover board. We check the existing insulation for moisture and replace anything that is wet before the new membrane goes on.
• Seam welding. Seams are hot-air welded and probed so that every lap is sealed.
• Flashing. Walls, curbs, pipes, drains and edges get membrane flashing and metal edge details made for the system.
• Drainage. We look at slope, drains and scuppers so water leaves the roof instead of ponding.

Our TPO Roofing Process, Step by Step

1. Inspection. We walk the roof, check the existing membrane, seams, flashing and drains, and look for wet insulation.
2. Written scope and quote. You get the system, thickness, attachment method, insulation, flashing details and warranty in writing.
3. Scheduling. We agree on the start date, roof access, staging and safety with you so the building can keep operating where the scope allows.
4. Preparation. Tear-off or surface preparation, deck repairs and insulation as specified.
5. Installation. Membrane installation, seam welding, flashing and edge metal.
6. Final walk-through. We check the seams and details, clean up the site and hand over your warranty documents.

TPO Roof Repair and Maintenance

Most TPO problems start at the details: open or poorly welded seams, punctures from foot traffic or dropped tools, flashing that has pulled away from walls and curbs, and clogged drains that let water sit on the roof. We find the source of the leak, weld in compatible TPO patches or new flashing, and clear the drainage path.

Regular inspections are the easiest way to make a TPO roof last. Property managers can set up an ongoing maintenance program with us so seams, flashing and drains are checked on a schedule and small issues are fixed early.

TPO Lifespan and Warranty

How long a TPO roof lasts depends on the membrane thickness, the manufacturer, the installation and the maintenance it gets. Manufacturers publish their own warranty terms for each system, and every quote we give lists both the manufacturer warranty and our workmanship warranty, so you know exactly what is covered before you sign.

What TPO Roofing Costs in Detroit

We do not quote a price per square foot before seeing the roof, because the numbers move a lot with the details. These are the factors that drive the cost of a TPO roof:

TPO vs EPDM vs PVC

All three are proven flat-roof membranes. The best one depends on the building and how the roof is used:

Re-Cover or Replace a TPO Roof?

A re-cover puts a new TPO membrane over the existing roof and can save time and disposal cost when the existing roof and deck are dry and sound and code allows another layer. A full replacement removes everything down to the deck. It is the right call when the insulation is wet, the deck is damaged or the roof already has the maximum number of layers.

TPO Roofing FAQs

TPO vs EPDM: which is better for a commercial flat roof in Michigan?

Choose TPO when you want a white, reflective roof with heat-welded seams, which suits buildings with high cooling loads and roofs that need strong seams. EPDM is a good fit when you want a proven rubber membrane that stays flexible in cold weather and the budget favors a simpler system. PVC, such as Duro-Last, is the better choice where grease or chemicals reach the roof. We recommend one after inspecting your building.

How long does a TPO roof last?

Service life depends on the membrane thickness, the manufacturer, the quality of the installation and how well the roof is maintained. Each manufacturer publishes its own warranty terms for its TPO systems, and your quote lists the manufacturer warranty and our workmanship warranty for your roof in writing.

Is TPO good in cold climates like Michigan?

Yes, TPO is widely used on commercial roofs in cold northern climates. What matters most in Michigan is the installation: seams must be welded and tested correctly, flashing details must handle snow and ice, and adhesives must only be used within the manufacturer’s temperature limits, so we schedule cold-weather work around those limits.

How much does TPO roofing cost in Detroit?

TPO roofing cost depends on the roof size, the membrane thickness, whether the old roof is torn off or re-covered, the insulation needed, the attachment method, the flashing details and access to the roof. We inspect the roof first and give you a free written quote with each of those items spelled out.

Can TPO be installed over an existing roof?

Sometimes. A TPO re-cover over an existing roof is possible when the existing roof and deck are dry and sound, the building code allows another layer and the manufacturer’s requirements for the substrate are met. If we find wet insulation or damaged decking, a tear-off is the better option.
