Single-ply roofing systems are one of the most widely used solutions for commercial buildings across Michigan, especially for low-slope roofs. Property owners and facility managers in Royal Oak often choose single-ply membranes because they offer reliable performance, predictable maintenance, and strong long-term value when installed correctly.
At Incore Restoration Group, we frequently work with commercial building owners who want a clearer understanding of how the three main single-ply systems compare. To speak with an expert, call 866-685-0009 today.
Single-Ply Roofing Systems Explained: TPO vs EPDM vs PVC
While all single-ply membranes share similar installation methods, the material differences between TPO, EPDM, and PVC can significantly impact durability, energy performance, and long-term maintenance.
What Is Single-Ply Roofing?
Single-ply roofing refers to a flexible membrane system installed in one continuous layer over insulation and a roof deck. These membranes are typically attached using mechanical fasteners, adhesives, or ballast, depending on the building design and performance requirements. Because the seams are heat-welded or sealed, single-ply systems provide strong water resistance and adaptability for commercial structures.
The most common single-ply materials used on commercial buildings are TPO, EPDM, and PVC. Each offers distinct benefits depending on climate, building use, and owner priorities.
TPO Roofing Systems
Thermoplastic Polyolefin, commonly known as TPO, is one of the most popular single-ply roofing options for commercial buildings in Royal Oak and throughout the Midwest. TPO membranes are typically white or light-colored, making them highly reflective. This reflectivity helps reduce heat absorption and can support lower cooling demands during warmer months.
TPO roofs are known for their strong seam integrity because the seams are heat-welded, creating a watertight bond. They are also resistant to ultraviolet exposure and chemical pollutants often found in urban environments. For owners looking for a balance between performance and cost, TPO is frequently an attractive option.
EPDM Roofing Systems
EPDM, or ethylene propylene diene monomer, is a synthetic rubber membrane widely recognized for its durability and flexibility. EPDM roofs are most commonly black, which allows them to absorb heat and perform well in colder climates. This can be beneficial for buildings that prioritize winter performance.
One of the standout features of EPDM is its resistance to cracking and splitting, even after years of temperature fluctuations. The material remains flexible over time, making it well-suited for large commercial roofs with expansion and contraction. EPDM systems rely on adhesive or taped seams, and when properly maintained, they offer long service lives.
PVC Roofing Systems
Polyvinyl chloride, or PVC, is a premium single-ply roofing option often selected for commercial buildings with specific performance needs. PVC membranes are highly resistant to chemicals, oils, and grease, making them ideal for facilities such as restaurants, manufacturing buildings, and food processing plants.
Like TPO, PVC seams are heat-welded, creating excellent resistance to leaks. PVC also offers strong fire resistance and long-term flexibility. While the initial investment can be higher compared to other single-ply systems, many owners choose PVC for its durability in demanding environments.
Comparing TPO, EPDM, and PVC
Choosing the right single-ply roofing system depends on how the building is used and what the owner values most. TPO is often selected for energy efficiency and overall value. EPDM is favored for durability and cold-weather performance. PVC stands out for chemical resistance and specialized commercial applications.
At Incore Restoration Group, we help commercial property owners in Royal Oak evaluate these systems based on roof condition, building function, and long-term ownership goals rather than focusing on material alone.
Making the Right Choice for Your Building
Single-ply roofing is not a one-size-fits-all solution. Factors such as roof traffic, drainage design, insulation requirements, and future maintenance plans all play a role in selecting the right membrane. A professional roof assessment ensures the system chosen delivers consistent performance and protects the building asset over time.

FAQ
Which single-ply roofing system is best for Michigan weather?
All three systems can perform well in Michigan when properly installed. The best choice depends on energy goals, building use, and maintenance expectations.
Can a single-ply roof be repaired instead of replaced?
In many cases, single-ply roofs can be repaired if issues are caught early. Regular inspections help extend roof life and avoid premature replacement.
How often should a commercial single-ply roof be inspected?
Most commercial roofs should be inspected at least twice per year and after major weather events to identify issues before they escalate.
