Decades of Proven Performance
For more than 50 years, CGT has delivered high-performance waterproofing solutions for commercial and industrial rooftops across North America.
Since the 1970s, our solutions have supported the installation of more than one billion square feet of high-performance PVC membrane, demonstrating proven performance, consistent quality, and long-term reliability.
From the beginning our priority has been clear: deliver roofing solutions that perform reliably in demanding conditions while keeping pace with modern roofing needs.
Why 50 Years of Experience Matters
In the roofing industry, longevity is more than a milestone. It reflects decades of experience, a drive for continuous improvement, and the ability to adapt to changing performance requirements.
Over this time, roofing systems have evolved through building codes, efficiency standards, and performance expectations. This requires manufacturers to constantly refine their manufacturing process and material usage.
For CGT, this experience has provided us with valuable insight on how roofing membranes perform in various climates, building types, and project requirements. It has also helped shape a manufacturing approach focused on consistency, quality, and long-term performance.
Today, that knowledge continues to influence the development of roofing solutions designed to meet the demands of modern commercial and industrial roofing applications.
Scaling Performance Across North America
Over five decades, CGT has played a key role in the growth and adoption of PVC roofing membranes across North America. Our membranes have been used across a wide range of projects, supporting consistent performance in varying conditions.
This type of presence within the industry reflects more than just scale. It represents years of manufacturing experience, innovation, and proven performance. As roofing demands have evolved, so has our approach. We strive to provide solutions which are aligned with modern building standards and performance expectations.
Supporting Over One Billion Square Feet of Roofing
Over the past 50 years, CGT has supported the installation of more than one billion square feet of PVC roofing membrane across North America.
This scale represents more than production volume. It also shows years of proven performance across a wide range of commercial and industrial roofing applications, across different environments. The experience gained from decades of manufacturing continues to influence how we approach product design, quality, and innovation today.
Innovation That Continues Today
While CGT’s history spans over five decades, our focus remains on the future.
The roofing industry continues to evolve with changing demands and performance expectations. Building owners, consultants, and contractors expect roofing systems that not only meet today’s standards but can deliver value for decades to come.
The lessons learned from our years of manufacturing experience continue to influence how we develop roofing solutions today.
The Evolution to Goliath Roofing Systems
To build on this strong foundation, CGT introduced Goliath Roofing Systems, bringing over five decades of expertise directly to market through our premium PVC roofing membrane.
Goliath represents everything we have developed at CGT over the past 50+ years, including consistent manufacturing quality, and a deep understanding of roofing performance.
As the only PVC roofing membrane manufactured in Canada, Goliath Roofing Systems reflects on our commitment to deliver reliable, high-performance solutions designed to meet the demands of today’s construction environment.
