Expert TPO Roofing Services

Q: Can I install TPO over my existing warehouse roof to save on costs?

In many cases, yes. This is known as a recover or overlay. If your building currently has only one layer of roofing and the underlying structural repair needs are minimal, we can often install TPO over the existing surface. This saves you the high cost of a total tear-off and disposal while still providing a full manufacturer warranty.

Q: What is the difference between 45-mil, 60-mil, and 80-mil TPO?

The mil refers to the thickness of the membrane. In Ohio, we generally recommend at least a 60-mil TPO for commercial applications. It provides a thicker weathering layer above the internal scrim, offering better protection against UV degradation and the physical stress of heavy Ohio snow loads compared to the thinner 45-mil entry-level options.

TPO Roofing Services

In the modern commercial roofing industry, business owners and facility managers are constantly seeking the perfect balance between upfront cost and long-term energy performance. TPO (Thermoplastic Polyolefin) has emerged as the premier solution for commercial roofing applications across the Midwest. At Mid Ohio Roofing, we provide expert TPO roofing services designed to withstand Ohio’s volatile weather while significantly reducing your building’s operational costs.

As a family owned company with over 25 years of experience, we serve as a leading commercial roofing contractor for Mt Perry, Newark, and the greater Central Ohio region. We specialize in the installation, repair, and maintenance of high-reflectivity TPO systems that offer a problem-free roof for decades.

What is TPO Roofing?

TPO is a single-ply, white reflective roofing membrane composed of a blend of polypropylene and ethylene-propylene rubber. Unlike older commercial roofing products, TPO is heat-welded at the seams. This process creates a monolithic, waterproof layer that is much stronger than taped or glued seams found in other flat roof systems.

The Benefits of a TPO System

Superior Energy Efficiency: TPO is a “Cool Roof” material. Its white surface reflects UV rays rather than absorbing them, which can lower your roof’s surface temperature by as much as 50°F to 60°F during a hot Ohio summer.
Cost-Effective Installation: TPO offers the performance of premium systems like PVC but at a more accessible commercial roof replacement cost.
Puncture and Chemical Resistance: It is highly resistant to tears, impacts, and exposure to common industrial chemicals, making it the ideal choice for warehouse roofing contractors.
Flexibility: TPO remains flexible during Central Ohio’s “freeze-thaw” cycles, preventing the cracks and brittleness often seen in an old roof.

According to the U.S. Department of Energy — Cool Roof Research, TPO’s white reflective surface can lower a building’s rooftop temperature by as much as 50°F to 60°F during peak summer conditions, significantly reducing the strain on HVAC systems and delivering measurable reductions in annual cooling costs for Central Ohio commercial property owners. This makes TPO one of the most energy-efficient commercial roofing choices available to Ohio businesses today.

TPO Performance in Central Ohio

In Central Ohio, commercial buildings are subject to extreme thermal shifts. A roof can experience a temperature swing of 100 degrees in a single week. According to the Cool Roof Rating Council (CRRC), reflective membranes like TPO can reduce peak cooling demand by up to 15%, which is a vital statistic for high-overhead businesses in the Mt Perry area.

Furthermore, the Ohio Department of Development continues to emphasize energy efficiency through programs like the Advanced Energy Fund, which has awarded millions in 2026 to support commercial retrofits. By combining high-quality TPO with modern polyisocyanurate insulation, we help your facility meet and exceed these local energy standards, potentially qualifying your business for state-level sustainability incentives.

Our TPO Roofing Services

We offer a full suite of services to ensure your commercial roofing investment is protected from day one.

New TPO Roof Installation

Whether you are building a new facility or need a re-roof project, our excellent roofing technicians handle the roof installation with precision. We offer multiple attachment methods, including:

Fully Adhered: The membrane is glued to the insulation, providing the best wind-uplift resistance.
Mechanically Attached: Using heavy-duty fasteners, this is a fast and secure method for most industrial roofing services.
Induction Welded: A modern technique that uses electromagnetic heat to bond the membrane to plates beneath the surface, reducing the number of penetrations.

TPO Roof Repair and Maintenance

Even the most durable flat roof needs attention. We provide specialized roof repairs that commercial buildings need to address seam failures, punctures from HVAC technicians, or ponding water. Our roofing maintenance tips include regular seam probing and debris clearing to maximize your system’s 30-year lifespan.

TPO Restoration and Coatings

If your TPO roof is aging but the insulation is still dry, we can apply specialized silicone coatings. This can save you the massive commercial roof replacement cost while renewing your UV protection and adding another 10 to 15 years to the roof’s life.

Frequently Asked Questions

How does TPO roofing hold up against Ohio’s hail and severe storms?

TPO is engineered to be highly impact-resistant. In Central Ohio, where spring storms often bring hail, TPO’s reinforced fabric scrim helps prevent punctures that would normally compromise an asphalt shingle roof. However, because Ohio ranks high for major hail events, we recommend a storm damage roofing inspection after any significant weather event to ensure the membrane hasn’t sustained “micro-fractures.”

Will a white TPO roof actually lower my Ohio business’s energy bills?

Yes, significantly. Unlike traditional dark-colored flat roof systems, TPO reflects the sun’s heat. In the humid Ohio summer, this prevents your HVAC units from overworking. Local Ohio business owners often report a 15% to 25% reduction in cooling costs after switching from a black EPDM or modified bitumen roof to a reflective TPO system.

How long does a TPO roof last in the Central Ohio "freeze-thaw" cycle?

A professionally installed TPO roof by Mid Ohio Roofing typically lasts 20 to 30 years. The key to longevity in Ohio is the heat-welded seams. While older glued seams can pull apart when the temperature swings from 70°F to 20°F in a single day, TPO’s welded seams remain flexible and watertight, preventing the common roof leaks that plague older commercial buildings.

Can I install TPO over my existing warehouse roof to save on costs?

In many cases, yes. This is known as a “recover” or “overlay.” If your building in Mt Perry currently has only one layer of roofing and the underlying structural roof repair needs are minimal, we can often install TPO over the existing surface. This saves you the high cost of a total tear-off and disposal while still providing a full manufacturer warranty.

Is TPO roofing slippery when wet or covered in Ohio snow?

White TPO membranes can be very slippery when wet or covered in a light dusting of frost or snow. For businesses that require frequent rooftop maintenance (such as accessing HVAC units), we recommend installing TPO walk pads. These are textured, heavy-duty strips that provide traction and protect the membrane from foot-traffic wear in high-use areas.

What is the difference between 45-mil, 60-mil, and 80-mil TPO?

The “mil” refers to the thickness of the membrane (1,000 mils = 1 inch). In Ohio, we generally recommend at least a 60-mil TPO for commercial applications. It provides a thicker “weathering layer” above the internal scrim, offering better protection against UV degradation and the physical stress of heavy Ohio snow loads compared to the thinner 45-mil entry-level options.
