When a commercial roof starts leaking, losing heat, or showing early signs of membrane failure, building owners usually look for a solution that won’t force a full tear-off or shut down operations for weeks. That search often leads them to the TTR Roofing Installations Process, a system known for restoring aging flat roofs with stronger insulation, better waterproofing, and a more durable protective layer. This article breaks down what the TTR® (Tri Thermal Roofing) System is, how the installation works, and why it consistently outperforms traditional roofing methods across North America.
What Is the TTR® Tri Thermal Roofing System?
The TTR® Tri Thermal Roofing System is a high-performance roofing solution offered by Ener-Spray. It was developed to extend the life of existing flat or low-slope roofs without a costly tear-off. The system begins with spray-applied polyurethane foam insulation followed by a fully adhered EPDM roofing membrane, all installed using a proprietary adhesive process. We bring the patented TTR® system to commercial and industrial clients in Western Canada, delivering stronger insulation, improved energy efficiency, and reliable waterproof protection.

TTR Roofing Installations Process: A Step-by-Step Guide
While every building has its own conditions, the TTR Roofing Installations Process generally follows a structured and efficient workflow designed to restore your roof without shutting down your operations. It begins with a detailed roof assessment, where technicians inspect moisture levels, insulation quality, and the condition of your existing membrane. Once the roof is cleared and cleaned, the crew applies spray polyurethane foam directly over the existing surface. This foam creates a seamless layer of insulation that fills gaps, strengthens weak areas, and improves the building’s thermal performance.
After the foam sets, a fully adhered EPDM membrane is installed using a specialized adhesive that bonds tightly to the insulated surface. This method eliminates the need for mechanical fasteners, reducing the risk of leaks and preventing thermal bridging. The final step includes detailing around edges, penetrations, and drainage points to ensure a complete waterproof seal.
Although the TTR® system is engineered to streamline installation and avoid a full tear-off, it is not a DIY project. Its performance depends on correct foam application, proper membrane adhesion, and trained technicians who understand the system’s specific requirements. Hiring certified professionals ensures your building receives the full benefits of the TTR approach—without shortcuts that could compromise long-term durability.
Key Benefits of Choosing the TTR® System
The TTR® System offers commercial clients a unique combination of financial and structural advantages that set it apart from traditional patch repairs or conventional single-ply membrane installations.
Exceptional Energy Efficiency
The spray-applied polyurethane foam (SPF) provides one of the highest R-values (resistance to heat flow) per inch of any commercial roofing insulation available. This thermal performance results in significant, measurable reductions in heating and cooling costs over the life of the roof. It is 60% cooler than conventional roofs.
Non-Disruptive Installation
Because the TTR System restores the existing roof without requiring a complete tear-off, there is minimal debris, noise, and interruption to the daily operations within your facility. This is a major advantage for operating businesses, hospitals, and schools.
Seamless Waterproofing
Unlike conventional roofing materials, which rely on seams, fasteners, and overlapping sheets that are vulnerable to failure, the TTR System is a monolithic (seamless) barrier. There are no seams to split, no fasteners to back out, and no gaps for water to enter, providing superior and reliable leak protection.
Durable and Lightweight
The installed system is incredibly durable, yet surprisingly lightweight. It won’t place undue stress on the building’s structure, and its robust composition resists hail damage and extreme weather fluctuations better than many traditional membranes.
Ensuring Quality: TTR® Testing, Certifications, and Performance
At Ener-Spray, we rely on verified, independent testing to demonstrate the strength, safety, and long-term reliability of the TTR® Tri Thermal Roofing System. The system has been evaluated by recognized laboratories across North America to ensure it meets strict performance standards for commercial and industrial roofing.
The TTR® assembly has undergone wind uplift testing through ACRC (American Construction Research Corporation) in Fort Lauderdale, a reputable facility that verifies how roofing systems withstand extreme wind conditions. Additional physical property testing — including membrane adhesion and overall material durability — was performed by PRI Construction Materials Technologies in Tampa, an industry-trusted testing lab.
Fire-related performance was evaluated by Southwest Research Institute in San Antonio, an independent research organization known for testing building materials under various fire and thermal exposure scenarios. The TTR® system also holds a Miami-Dade County Notice of Acceptance (NOA), confirming it is approved for use in High Velocity Hurricane Zones — one of the most demanding roofing environments in North America.
These confirmed tests and approvals reflect our commitment to delivering a roofing system that is not only energy-efficient and long-lasting, but also backed by recognized performance standards for wind resistance, fire safety, and structural integrity.
Conclusion
When your building starts showing signs of leaks, heat loss, or aging membrane damage, finding a long-term roofing solution becomes urgent. The TTR roofing installations process provides a clear, reliable path forward—strengthening insulation, improving waterproofing, and extending the life of your existing roof without the cost or disruption of a full tear-off. With its seamless foam-and-membrane assembly, independently tested performance, and proven results across harsh climates, the TTR® System directly addresses the common pain points building owners face.
