Not every commercial building in Livonia, MI, needs the same membrane, and experienced single-ply roofers do not treat them like they do. At Core Values Construction, we work with Michigan building owners to match the right TPO, PVC, or EPDM systems to each building’s specific conditions before a single roll goes on the roof.

How Single-Ply Roofers Choose the Right Membrane
A membrane that performs well on a light-use retail strip in Livonia may be the wrong choice for an industrial facility with rooftop chemical exposure or heavy HVAC foot traffic. The variables that go into a proper spec are not complicated, but they do require someone who knows what to look for and is honest about the tradeoffs between systems. Michigan’s climate adds another layer to that decision because the thermal cycling between cold winters and humid summers puts real stress on every part of the membrane assembly.
The first question a qualified single-ply roofer asks is what the roof surface actually has to deal with. Chemical exposure is the clearest differentiator. Buildings that vent grease, solvents, or industrial gases through the roof have a membrane compatibility requirement that overrides most other factors. PVC is the standard answer there because it holds up to chemical contact that would degrade TPO or EPDM over time. A roofer who recommends TPO on a restaurant or food processing facility without checking exhaust placement is not doing the full job.
Foot traffic from HVAC service, rooftop equipment maintenance, and utility access is the second variable. All three single-ply membranes can handle some foot traffic, but they are not equal. Thicker membrane specifications, 60-mil or 80-mil rather than 45-mil, make a measurable difference on roofs that see regular service personnel. A Michigan building with multiple rooftop HVAC units being serviced twice a year is a different spec than a simple low-traffic warehouse roof, and the membrane thickness recommendation should reflect that.
Factors that Contribute
Drainage is one of the factors building owners rarely think about until water starts ponding. On a flat commercial roof in Livonia, even modest drainage problem concentrates standing water in low areas after every rain. EPDM holds up to ponding water better than most, but no single-ply membrane is designed to sit under standing water indefinitely. A proper pre-installation evaluation identifies low points, inadequate drain sizing, and blocked scuppers before the membrane goes down. Applying a new system over unresolved drainage issues shortens the lifespan of that system regardless of material quality.
Insulation compatibility and R-value requirements are the other piece most building owners overlook. Michigan’s energy code has specific requirements for commercial roof assemblies, and the insulation layer under the membrane affects both performance and code compliance. TPO and PVC systems are typically installed over polyisocyanurate insulation boards. EPDM is compatible with a wider range of substrates and is often the system of choice on retrofit projects where the existing insulation is being retained. Matching the membrane to the insulation assembly rather than specking them independently is how experienced single-ply roofers avoid problems after installation.
System Knowledge Matters
Manufacturer brands in the single-ply market, Carlisle, Duro-Last, IB Roof Systems, GAF, and others, all produce quality membranes. The difference between a roof that performs for 25 years and one that needs repair in five rarely comes down to which brand is on the roll. It comes down to whether the contractor understood the building, specified the right system thickness and attachment method, and executed the seam work and flashings correctly. Seams and flashings are where single-ply systems fail. A building with perfect field membrane but poorly executed penetration flashings around HVAC curbs is going to leak at those flashings.
The Right Single-Ply Roofers
Core Values Construction has been installing single-ply systems on commercial buildings across Michigan for over 20 years, including large-scale projects that required precise system selection and consistent execution across hundreds of thousands of square feet. That experience is what goes into the recommendation we make for every Livonia, MI, building we assess. Call us at 517-260-3957 and let our single-ply roofers take a look at what your building actually needs.
FAQ
Can a single-ply membrane be installed over an existing roof in Michigan?
In many cases yes, provided the existing membrane is dry and the total assembly meets current energy code requirements for insulation R-value.
How does Michigan’s freeze-thaw cycle affect single-ply membrane selection?
EPDM is the most cold-flexible option and tolerates freeze-thaw stress well, while TPO and PVC rely on quality heat-welded seams to maintain integrity through thermal movement.
What membrane thickness do single-ply roofers typically recommend for commercial buildings?
60-mil is the most common commercial specification, with 80-mil recommended for buildings with heavy foot traffic or demanding service conditions.
Does the attachment method affect how a single-ply membrane performs in Michigan wind?
Yes, fully adhered systems offer better wind uplift resistance than mechanically fastened systems and are often the right choice for taller or more exposed commercial buildings.
