Thermal-Tec MR Multi-Ply® Roofing System

The MR Multi-Ply® Roofing System is specifically designed for pitched metal roofs. It starts with a layer of asphalt, nature’s rust inhibitor. This prevents the oxidation of existing rust. We then apply a direct-to-metal, FULL MEMBRANE (no fasteners like a single-ply system) to the ENTIRE Roof, with a still broom, covering all fasteners and seams. This provides waterproofing.

Next, we apply another layer of asphalt. We let this cure with your building as it expands, contracts, and works with the racking of your structure. We then come back and apply another layer of asphalt and a final layer of a tough, reflective granule or aluminum finish. Our solution is unlike any other. It is specifically designed to expand and contract with your metal roof. Additional benefits include an extra 100,000 pounds of tensile strength added to your entire roof and a “Class A” fire rating - an essential requirement for facilities with aggressive manufacturing environments. Here's how it works.

Base Roof Panel

The MR Multi-Ply® Roofing System is designed for pitched metal, transite, asbestos, and fiberglass roofs.

First Asphalt Layer

A layer of Multi-Vulcan I Asphalt is applied directly to the roof, forming the base of the system.

Polyester Membrane

The polyester membrane, Vulcan-Ply, adds strength and flexibility.

Second Asphalt Layer

A second layer of Multi-Vulcan I Asphalt seals in the membrane and provides further protection.


A final layer of energy-efficient Vulcan-slag granules are added to ensure your roof stays cool.

Alternative Energy Star Finish

Energy Star Reflective, and colored finishes also available.

Safety - It’s Who We Are

Nationally Recognized Safety Program

Thermal-Tec's Safety Program is recognized nationwide. Our commitment to maintaining the best safety record in the commercial roofing industry is a promise we made to our employees a long time ago. It still stands today. We have been recognized by many organizations including having won the Associated Buildings and Contractors Platinum Level Safety Award consecutively for more than a decade. In 2009 we received top honors and were awarded the National Safety Excellence Award.


Dedicated to Safety

Attitude towards safety is everything. Those of us who have been in the trade for a while understand how imperative it is to set the example. From day one, we've made safety and professionalism the foundation of our services. We don't do it for the recognition - we do it because it's who we are. This attitude is set forth by the owners and extends all the way down to our youngest employees.

No Recordable OSHA Incidents

A company's safety record and annual injury reports will usually inform consumers about the type of company they're engaging with. Our safety program is designed to go above and beyond OSHA regulations and standard compliance measures. We revisit and revise our safety program annually - always looking for ways to be better.

We Know Your Challenges

JW Aluminum
Square Feet:
Industry: Aluminum Production
JW Aluminum was founded in Mt. Holly, South Carolina in 1979 as Jim Walter Metals – a single-facility operation with about 10 employees. Since then, JW Aluminum has grown to become the leading aluminum rolled products company in the world, with one of the most diverse product lines in the aluminum industry. When JW Aluminum was having problems with leaks due to the corrosive environment that their process causes Thermal-Tec had a solution. JW Aluminum choose the MR Multi-Ply® Roofing System based on our reputation throughout the Primary & Secondary Smelting Industry. With Thermal-Tec’s exceptional safety record there were no worries about ceased production due to leaks.
Square Feet:
Industry: Aluminum Production
In 2015 Constellium purchased Wise Alloys - founded in 1941 to manufacture aluminum sheet for airplanes during World War II. The 4 million sq. ft. plant, now owned by Constellium, casts molten aluminum into sheet ingot. The ingot is then rolled into coils of aluminum sheet approximately 1/100 of an inch thick. The facility has a current capacity for finished products of 950 million pounds per year. Due to the nature of Constelliums' process, they needed a roofing system that was able to withstand the aggressive environment. Thermal-Tec has installed the MR Multi-Ply® over multiple sections of the plant and continues to work with Constellium, ensuring they can produce rain or shine!
Bonnell Aluminum
Square Feet:
Location: Carthage Bush Creek, TN
Bonnell manufactures mill-finished anodized and painted aluminum. When Bonnell was experiencing roof leaks on the building and internal gutter we offered the best solution for handling the problem. More than a coating and a superb safety record, Thermal-Tec helped Bonnell Aluminum solve the problem of leaks.
Crown Battery
Square Feet:
In 1926, William J. Koenig, a German immigrant in pursuit of the American dream, opened the doors to a small battery repair shop in Fremont, Ohio. More than 85 years of experience with lead-acid batteries, chargers, and related accessory products have made Crown Battery a leader in the global battery industry. Due to the nature of producing lead-acid batteries, the acids and chemicals corroded the roof over time which in turn produced leaks on the roof. Thermal-Tec has been working with Crown Battery for over 14 years providing them a reliable roofing solution with the MR Multi-Ply® Roof System that is resistant to harsh chemicals.
