Today's Popular Roofing Membranes: What Are the Differences?

Dear Customers,

At Cotterman & Company Inc., we pride ourselves on offering the best roofing solutions tailored to your specific needs. In today’s newsletter, we’re exploring three popular roofing membranes used in commercial and industrial roofing: TPO, PVC, and EPDM. Each of these options offers unique strengths to suit a variety of building requirements.

Thermoplastic Polyolefin (TPO)

History:

Introduced in the early 1990s, TPO has become a favorite due to its energy efficiency and cost-effectiveness.

Usage:

TPO is ideal for warmer climates, thanks to its reflective surface that helps reduce energy costs.

Installation:

TPO is installed in large sheets, with seams that are heat-welded to create a durable, leak-resistant roof.

Quality and Life Expectancy:

TPO membranes typically last 15 to 30 years, depending on membrane thickness and installation methods. Continuous advancements in technology are enhancing its long-term performance.

Polyvinyl Chloride (PVC)

History:

PVC has been in use since the 1960s, known for its flexibility and chemical resistance.

Usage:

PVC is a strong choice for environments where chemical resistance, fire protection and energy efficiency are crucial.

Installation:

Similar to TPO, PVC membranes are installed with heat-welded seams, ensuring a watertight and robust seal.

Quality and Life Expectancy:

PVC typically lasts 15 to 30 years, depending on the thickness of the membrane and the installation technique used. Its performance is reliable across various environmental conditions.

Ethylene Propylene Diene Monomer (EPDM)

History:

EPDM has been a go-to roofing membrane since the 1960s, valued for its longevity and weather resistance.

Usage:

Particularly suited for colder climates, EPDM excels in extreme temperatures and offers excellent UV resistance.

Installation:

EPDM is installed using adhesives or seam tape, making it versatile for roofs with complex designs.

Quality and Life Expectancy:

EPDM membranes also typically last 15 to 30 years, with durability influenced by membrane thickness and installation methods. Its resilience in harsh weather makes it a dependable choice.

What’s the Difference?

All three roofing membranes—TPO, PVC, and EPDM—offer dependable performance, with a lifespan of 15 to 30 years depending on factors like membrane thickness and installation techniques. TPO is great for energy efficiency, PVC excels in chemical resistance, and EPDM is ideal for long-term weather performance.

At Cotterman & Company Inc., we’re here to help you choose the roofing solution that best fits your needs. Whether you prioritize energy savings, chemical resistance, or durability in extreme weather, we have the expertise to guide you.

Thank you for trusting us with your roofing needs. We look forward to continuing to provide you with the best products and services in the industry.

That simple marking told a big story.

Fri, 27 Feb 2026 13:51:20 GMT

Last week, after the snow and ice finally cleared here in Dayton, Cotterman & Company Inc. completed a roof evaluation on a large warehouse facility that had recently started experiencing leaks.

As part of the inspection, a date stamp was located on the membrane: DL ’99.

That simple marking told a big story.

The building is protected by a Duro-Last PVC roofing system that was installed in 1999. After 25 years of service, the system has performed well — a testament to proper installation, maintenance, and the long-term durability of PVC roofing systems in commercial applications.

However, even well-performing systems eventually reach the end of their service life. With leaks beginning to show and the roof now at the 25-year mark, the timing makes sense to begin planning for replacement rather than continuing reactive repairs.

Cotterman & Company Inc. has provided reroof options so the customer can evaluate what best fits their long-term goals and budget. A key part of the discussion is warranty coverage. Once a new roofing system is installed, the facility can secure:

20-year
25-year
30-year

Watertight material and labor manufacturer warranties — helping protect their investment for decades to come.

Finding a date stamp during an evaluation may seem like a small detail, but it provides valuable insight. It helps establish system age, guide realistic expectations, and support proactive planning instead of emergency decision-making.

If you manage or own a commercial facility and are unsure of your roof’s age or condition, a professional evaluation can provide clarity — and help you plan ahead before minor leaks turn into major disruptions.

Date stamp was located on the membrane: DL ’99.

Project Spotlight: Emergency Hospital Roof Replacement

Fri, 09 Jan 2026 14:35:56 GMT

Project Spotlight: Emergency Hospital Roof Replacement

After severe storms rolled through the area, our Service Department was called to a local hospital to investigate new roof leaks. Once onsite, our technicians identified storm damage that had compromised the termination bars and caused full delamination of the adhered EPDM roof system from the insulation.

Our team immediately made emergency repairs to stop active leaks and prevent interior damage. Following that, we quickly performed a full roof evaluation alongside the facility’s director to plan a more permanent solution.

During the investigation, it was determined that two large RTU units, each measuring roughly 18’ x 45’, were located in the areas with fully delaminated roofing. The roofs in these areas were only held down by the perimeter termination bar. When the units were running at full speed, the EPDM roofing ballooned from the air pressure, creating unsafe conditions for both the building and anyone on the roof.

Given the urgency and the sensitivity of one unit supplying air to surgery rooms, our team developed a plan to replace the roofing without adhesives, avoiding any fumes that could impact patient care. Within days, Cotterman crews were on-site installing a 60 mil white reflective TPO roofing system using the Rhinobond induction method, providing a safer, more energy-efficient solution that minimized disruption and kept the hospital fully operational.

Another example of how Cotterman & Company responds quickly and delivers solutions that protect critical facilities with no shutdowns, no delays, and no compromises.

Emergency Line: Open 24/7 (800) 713-3190

Before: Full delamination of the adhered EPDM roofing system.

After: Installed a 60 mil white reflective TPO roofing system using the Rhinobond induction method.

Fall Reminder: Don’t Overlook Your Gutters & Drains!

Wed, 08 Oct 2025 15:01:28 GMT

Fall Reminder: Don’t Overlook Your Gutters & Drains!

As the seasons change, one of the most important steps in protecting your commercial or industrial roof is keeping gutters, downspouts, and drains clear.

At Cotterman & Company, Inc., we see it too often:

Gutters and downspouts rusted out because they weren’t cleaned year after year.
Leaks that started small but turned into major repair needs.
Buildings that skipped preventative maintenance, only to face frozen drains and costly water damage once winter hits.

A little maintenance now can save you a lot of headaches later. That’s why we recommend scheduling a roof inspection with our professional team before the cold weather sets in.

Tapered Insulation in Commercial Roofing

Tue, 06 May 2025 20:40:58 GMT

Tapered Insulation in Commercial Roofing – Function Meets Efficiency:

At Cotterman & Company Inc., we’re not just about installing roofing systems, we’re about building smart, long-lasting solutions tailored to your facility’s unique needs. One critical component in many commercial and industrial roof systems is tapered insulation. Whether your building is brand new or decades old, understanding when and why to use tapered insulation is key to protecting your investment.

Slope Starts at the Deck
In many commercial and industrial buildings, slope is engineered directly into the roof deck during construction. Decking materials like steel, wood, concrete, and tectum are commonly used, and in many cases, these are designed to provide a slope toward drains or scuppers.

However, not all decks are sloped, and when they’re flat, water has nowhere to go. This is where tapered insulation comes in. It allows us to add slope above the deck, using the insulation itself to guide water toward the roof’s drainage system.

What Is Tapered Insulation?
Tapered insulation is a customized system usually made of polyisocyanurate (polyiso) or expanded polystyrene (EPS) that’s cut and configured to direct water toward drains, gutters, or downspouts. The insulation is designed specifically for the roof layout of the building, and it can be installed in one of two ways:

Mechanically fastened to the roof deck
Adhered using adhesives, which is common when slopes grow in depth and board sizes increase

Custom Slope Options

Tapered insulation systems can be built to slope:

1/8” per foot
1/4” per foot
1/2” per foot

These gradual slopes ensure positive drainage, which helps avoid standing water, premature membrane aging, and structural stress.

As the slope increases, the insulation boards become thicker, which often requires longer fasteners or additional adhesives. That added thickness is also where tapered insulation starts to make a big impact on thermal performance.

Energy Code & R-Value Benefits

Ohio’s energy code requires a minimum R-30 insulation value on low-slope commercial roofs. Tapered insulation systems often exceed this baseline because of their layered build-up boosting energy efficiency and comfort within the facility.

However, that added thickness and customization come at a cost. Tapered systems typically cost more upfront than straight insulation on a sloped deck. But the long-term benefits, improved drainage, higher R-value, and better protection can make it a smart investment.

Maintenance Matters

Like all roofing systems, a tapered insulation system needs to be protected. Routine preventative maintenance can:

Prevent water intrusion
Preserve the insulation’s thermal performance
Keep the roof eligible for a future overlay, avoiding the expense of a full tear-off and replacement

Final Thoughts

Tapered insulation is a powerful tool in flat and low-slope roofing solving drainage issues while boosting performance. Whether you’re designing a new facility or addressing problems on an existing roof, Cotterman & Company is ready to help you determine the right solution.

The Costly Consequences of Wet Insulation on Low-Slope Roofs

Wed, 05 Mar 2025 20:35:18 GMT

The Costly Consequences of Wet Insulation on Low-Slope Roofs

As industrial and commercial roofs age, various types of failures can occur. Small issues, such as puncture holes, failed seam welds in thermoplastic membranes, deteriorated adhesives in EPDM rubber roofs, and general wear from exposure can allow water infiltration. Over time, this water becomes trapped in the roofing insulation, leading to serious and costly problems.

Why Wet Insulation Is a Major Concern

When insulation retains moisture, it can cause:

✅ Organic Growth & Mold – Damp conditions create an environment for mold, which can impact indoor air quality.

✅ Rusting of Metal Decks – Trapped moisture accelerates corrosion, weakening the roof structure.

✅ Interior Damage – Ceilings, walls, and equipment inside the building are at risk of water-related deterioration.

The Importance of Protecting Your Insulation

One of the biggest benefits of preventative maintenance is cost savings during a future re-roof. In many cases, existing insulation can remain in place when installing a new membrane, significantly reducing material and labor costs. However, if insulation is compromised by water, a full tear-off and replacement may be necessary dramatically increasing project costs.

How to Extend the Life of Your Roof & Insulation

✔️ Regular inspections to identify risks early

✔️ Prompt repairs to prevent water infiltration

✔️ Proactive maintenance to extend the lifespan of your roofing system

Not sure if your roof’s insulation is at risk? Contact Cotterman & Company Inc. for a professional roof evaluation. Protect your investment and avoid costly replacements by addressing issues before they escalate.
