EPDM Roofing and Rubber Roofing Systems

EPDM Roofing & Rubber Roofing Systems

Proven for over 45 years, EPDM roofing systems are a popular choice for commercial buildings due to their low maintenance needs and excellent weather resistance. This makes them ideal for Grand Rapids' harsh climate and unpredictable weather patterns.

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.

FleeceBACK Roofing System

FleeceBACK® Roofing System

FleeceBACK roofing systems from Carlisle combine the best features of EPDM and TPO to deliver exceptional performance and long-lasting protection for your commercial flat roof. Here's what makes FleeceBACK stand out:

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.

Modified Bitumen Roofing System

Modified Bitumen Roofing System

Modified bitumen roofing systems from Sherriff Goslin offer a unique combination of strength, flexibility, and long-lasting performance.

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

Lastly, we have built-up roofing, a traditional and trusted option for commercial flat roofs. It's constructed by layering asphalt, fiberglass mats, or special felts, creating a thick and long-lasting roofing membrane. This option includes an insulation board, a base sheet, additional waterproofing layers, and finishing materials like gravel or stone. The thorough construction of a built-up roof guarantees strength and durability.

Additionally, while known for its affordability on both new and existing buildings, built-up roofing does require periodic maintenance to maximize its lifespan. Here at Sherriff Goslin, we can design and install a built-up roof that offers excellent overall ruggedness and can withstand even moderate foot traffic.
