Cold Applied Roofing Systems

At Nusite Group, we provide expert cold-applied roofing solutions for commercial and industrial properties throughout Toronto and the GTA. As a trusted commercial roofing contractor, we specialize in installing cold-applied waterproofing membranes that offer strong adhesion, minimal disruption, and long-term protection. Unlike traditional hot-applied systems, cold-applied roofing uses solvent-based or water-based adhesives, allowing for a safer, low-odor installation without the need for open flames or heavy equipment.

These systems are ideal for complex roof structures, sensitive environments, and projects where safety, speed, and environmental conditions are top priorities. Cold-applied membranes form a continuous, seamless waterproof barrier that resists cracking, UV degradation, and water infiltration—making them a reliable choice for commercial and industrial buildings across Toronto. Whether you’re restoring an aging roof or starting a new build, our team ensures every cold-applied roofing system is installed to meet high-performance standards.

Eco-friendly Flameless (Cold Apply) Flat Roofing System

Using cold-applied technology, Nusite Group delivers flat roofing systems that are both environmentally responsible and highly durable—making them a smart choice for commercial roofing projects across Ontario. These flameless systems eliminate the need for torches or heated materials, significantly reducing fire hazards during installation and allowing work to proceed safely in sensitive environments like hospitals, schools, or food production facilities.

Because there’s no need for open flames, using cold-applied methods results in cleaner, quieter job sites and lower emissions, aligning with modern sustainability goals. The flexible membranes used in this process adhere seamlessly to the roof substrate, creating a watertight seal that performs reliably in Ontario’s diverse climate conditions. Whether you’re managing a large-scale roofing project or upgrading a single facility, our cold-applied flat roofing systems offer a safe, efficient, and eco-conscious solution from installation through long-term performance.

What Is A Flameless (Cold Apply) Flat Roofing System?

A flameless, or cold-applied, flat roofing system is a type of commercial flat roof that uses cold-applied materials—typically liquid or adhesive-based waterproofing compounds—instead of heat or open flames to secure membranes. This method is ideal for properties in Toronto where fire safety, environmental conditions, or site restrictions make traditional hot-applied roofing less practical or more hazardous.

In a cold-applied system, waterproofing membranes are adhered to the roof deck using solvent- or water-based adhesives. These materials cure without the need for torching, making them safer for both installers and building occupants. For commercial flat roofs, this approach offers a seamless, durable barrier against water infiltration, while reducing installation risks and ensuring compliance with local building codes across Toronto. It’s an increasingly popular choice among commercial property owners looking for low-impact, high-performance roofing solutions.

FAQ

What are the benefits of using cold-applied roofing systems for commercial properties in Toronto?

Cold-applied roofing systems offer multiple benefits for commercial buildings in Toronto, including safer installation, minimal disruption, and excellent waterproofing performance. Because they use cold-applied materials instead of heat or flames, they reduce fire hazards and are ideal for sensitive sites like hospitals, schools, and food facilities. These systems form a seamless, watertight barrier, making them a reliable choice for long-term protection in the Greater Toronto Area’s variable weather conditions.

How long does a cold-applied roofing system last?

With proper installation and maintenance, a cold-applied roofing membrane can last 20 to 30 years. The longevity of the system depends on the quality of the materials used, environmental exposure, and how well the roof is maintained over time. Regular inspections and timely repairs help extend the lifespan of your commercial flat roof, especially in climates like Toronto’s where freeze-thaw cycles are common.

Can cold-applied membrane systems be used for roof repairs as well as new installations?

Yes, cold-applied membrane systems are highly effective for both new roof installations and commercial roof repairs. They’re especially beneficial for patching or restoring aging flat roofs without needing a complete tear-off. Their versatility and strong adhesion make them a go-to option for Toronto roofing contractors handling restoration and repair projects across the GTA.

Are cold-applied roofing systems suitable for all types of commercial and industrial buildings?

Cold-applied systems are suitable for most flat or low-slope commercial and industrial roofs, including warehouses, office complexes, retail buildings, and multi-use properties. Their flame-free application makes them particularly valuable in densely populated urban areas like Toronto, where building safety and noise reduction are top priorities for property managers and owners.

How does cold-applied roofing compare to traditional hot-applied roofing methods?

Cold-applied roofing eliminates the risks associated with open flames and heated equipment, making it a safer and more environmentally friendly alternative to traditional hot-applied systems. It also allows for quicker, cleaner installation with fewer odors and less disruption to building occupants. Many commercial roofing contractors in Toronto now recommend cold-applied solutions for their efficiency, safety, and strong long-term waterproofing performance.
