EPDM Roofing and Rubber Roofing Systems

EPDM Roofing & Rubber Roofing Systems

Proven for over 45 years, EPDM roofing systems remain a trusted option among commercial roofing materials. Known for their weather resistance and minimal upkeep, EPDM membranes can expand and contract without cracking, making them well-suited for long-term performance. They also resist UV exposure and ponding water, two of the most common causes of roof deterioration.

These features make EPDM an ideal choice for South Bend’s harsh climate, where temperature swings, snow, and heavy rain are common. Because installation requires no specialized equipment, EPDM is often a faster and more cost-effective option compared to other roofing materials used on commercial buildings.

Energy Efficiency

The traditional black EPDM membrane absorbs sunlight, helping to reduce heating costs during cold winters.

Snow Removal

EPDM's dark surface promotes snowmelt, preventing heavy snow accumulation that can damage your roof.

Cost-Effective

EPDM is easy and fast to install without specialized tools, keeping installation costs down and minimizing the risk of unexpected repairs.

TPO Roofing Systems

TPO Roofing Systems

TPO, or thermoplastic polyolefin, roofing systems are rapidly becoming the premier choice in commercial roofing. Valued for their reflective properties and energy efficiency, TPO membranes come in both white and tan options. This translates to reduced energy use for your building, making TPO a certified Cool Roof Rating Council (CRRC) product and a favorite of Energy Star®.

But beyond energy savings, TPOs are known for their fast and easy installation thanks to prefabricated accessories that streamline the process and minimize roof prep time.

Energy Efficiency

TPO membranes reflect sunlight, lowering rooftop temperatures and reducing cooling costs during warm months.

Quick Installation

Prefabricated accessories and heat-welded seams allow for faster installation with less prep work and fewer delays.

Flexible Color Options

Available in white, tan, and gray, TPO offers design flexibility while meeting modern energy and code requirements.

FleeceBACK Roofing System

FleeceBACK® Roofing System

FleeceBACK roofing systems from Carlisle combine the most durable features of EPDM and TPO into one high-performance membrane. Built for strength and longevity, FleeceBACK includes a reinforced fleece layer that increases puncture resistance, wind uplift strength, and overall durability across a wide range of conditions.

It also offers strong adhesion to insulation and deck surfaces, making it ideal for buildings that experience heavy foot traffic or fluctuating temperatures. This system is often used in commercial roof replacement projects where added resilience is critical. It performs well in areas with wind exposure, rooftop equipment, or demanding weather patterns.

Unmatched Durability

Featuring a strong fleece backing and Carlisle's trusted membranes, FleeceBACK offers superior resistance to harsh weather, punctures, and tears.

Wind Uplift Champion

With a wind uplift resistance of up to 120 miles per hour, FleeceBACK provides peace of mind even in extreme weather conditions.

Energy Efficiency

Available in reflective options, this flat roofing system reduces your building's energy consumption due to its reflective properties and white/tan color.

Asphalt Saturation Protection

For hot-mopped or cold-applied FleeceBACK systems, Carlisle's patented AFX fleece offers additional protection against hot asphalt damage.

PVC Roofing System

PVC Roofing Systems

Polyvinyl chloride (PVC) roofing systems are a proven performer in the commercial roofing industry as they offer a balance of energy efficiency and affordability. Similar to EPDM and TPO, PVC membranes come in reflective varieties, making them Energy Star®-rated and CRRC-certified.

Additionally, PVC has superior resistance to the chemicals commonly found on rooftops, including greases, oils, and acids. This makes PVC a strong choice for buildings exposed to these elements.

Chemical Resistance

PVC membranes resist damage from rooftop exposure to grease, oil, and acidic byproducts often found near vents or equipment.

Energy-Efficient Design

Light-colored, reflective surfaces help reduce rooftop heat absorption and lower cooling demands during warmer months.

Proven Durability

With a lifespan that often exceeds 20 years, PVC delivers long-term performance with minimal maintenance or repairs.

Modified Bitumen Roofing System

Modified Bitumen Roofing System

Modified bitumen roofing systems from Sherriff Goslin combine strength, flexibility, and long-term performance for commercial buildings. These systems are made with asphalt-based membranes reinforced with fiberglass or polyester and modified with rubber or plastic polymers. This layered construction improves resistance to weather, foot traffic, and thermal movement, making it a dependable option for low-slope commercial roofs.

With installation methods that include heat-welded, cold-applied, and self-adhered applications, modified bitumen offers versatility across different roof structures. It’s especially effective in climates with shifting temperatures, where flexibility and adhesion are critical to long-term protection.

Strength & Flexibility

The combination of asphalt with modifiers and reinforcing agents like fiberglass gives you modified bitumen's tough, rubbery material that's both durable and flexible.

Enhanced Durability

A final layer of mineral granules provides added protection against the elements, extending the lifespan of your roof.

Consistent Quality

Manufactured in a controlled environment, modified bitumen systems offer consistent quality and reliable performance.

Ideal for High Traffic

More flexible than built-up roofing systems, modified bitumen is a suitable choice for roofs with high foot traffic.

Built-Up Commercial Roofing System

Built-Up Commercial Roofing System

Built-up roofing is a traditional, layered system commonly used on flat commercial roofs. It’s assembled using alternating layers of asphalt, fiberglass mats, or roofing felts to form a thick, durable membrane. The system also includes a base sheet, insulation board, waterproofing layers, and a protective surface like gravel or stone.

Built-up roofs are valued for their durability and consistent performance across a variety of building types. They hold up well under moderate foot traffic and offer strong resistance to water and weather. While this system is often chosen for its lower upfront cost, it does require routine maintenance to extend its service life. Sherriff Goslin installs built-up commercial roofing systems designed to balance performance and long-term value.

Layered Protection

Multiple layers of asphalt, felt, and surfacing materials create a thick barrier that resists water penetration and improves roof longevity.

UV & Weather Resistance

The surface layer—typically gravel or a reflective coating—helps protect the membrane from sun exposure, temperature swings, and surface wear.

Long-Term Value

Built-up systems offer proven durability with proper upkeep, making them a reliable option for buildings with long-term occupancy plans.

Commercial Flat Roofing Systems FAQs

Which Flat Roof System Is Right for My Commercial Building?

Choosing the right flat roof depends on several factors, like climate, budget, and the specific needs of your business. For example, EPDM roofing might be a great option for long winters due to its ability to absorb sunlight and melt snow. On the other hand, if energy efficiency is a top priority, TPO roofing, with its reflective properties, could be ideal.

Sherriff Goslin can assess your situation and recommend the best flat roof system for your needs. We'll explain the benefits of each option and help you find a solution that perfectly aligns with your requirements. Contact us today to get started!

How Long Does a Flat Roof Replacement Take?

This can vary depending on the size and complexity of your roof, as well as the chosen roofing system. Generally, smaller, simpler roofs can be replaced in a few days, while larger, more complex projects may take a bit longer. Our team will provide a detailed timeline during the free consultation process.

We understand the importance of minimizing disruption to your business, and we'll work efficiently to complete the project as quickly as possible while maintaining the highest quality standards.

How Much Does a Flat Roof Repair Cost?

The cost of repairs depends on the size of your roof, the extent of damage, and your chosen roofing system. Modified bitumen roofing, for instance, is typically a more budget-friendly option compared to PVC. However, the long-term benefits of PVC might make it a worthwhile investment for some businesses.

The best way to get an accurate estimate for your specific needs is to schedule a free consultation with Sherriff Goslin. We'll provide a transparent quote that outlines all the costs involved, so you can make an informed decision about your flat roof project.

Are Metal Roofs Ever Used for Commercial Flat Roofing?

Metal roofs are sometimes used on low-slope commercial buildings but are not ideal for fully flat applications. Most commercial flat roof systems rely on a roofing membrane like TPO, PVC, or EPDM, which performs better in terms of drainage, waterproofing, and long-term sealing. However, for structures with minimal slope, standing seam metal panels can be an option when paired with proper insulation and underlayment.

While metal is more commonly seen in residential roofing or steep-slope commercial buildings, it still plays a role in some flat roof applications. Businesses considering metal should evaluate the slope, drainage capacity, and overall climate conditions. Commercial roofing services can help determine if metal aligns with the structural needs and performance expectations of your building.

What Should I Expect When Replacing Your Roof on a Commercial Building?

A full replacement requires evaluating existing roof issues, identifying damage, choosing the right system, and coordinating professional roof installation. Factors like deck condition, insulation needs, and building use all affect which material is best. Choosing an experienced contractor ensures the process is thorough and avoids unexpected problems.

Look for commercial roofing services that offer clear timelines, detailed estimates, and strong project management. A company with industry-leading experience will provide peace of mind by minimizing disruptions to your operations and delivering lasting results. Every decision, from materials to scheduling, should be based on performance and long-term value.
