➡️ Our team is available 24/7 for any flat roof emergency in Montreal. Act quickly to limit damage and trust responsive, efficient roofing professionals.

At Toitures J.S.B., we carry out commercial flat roofing projects using elastomeric membrane systems across the entire island of Montreal. As a commercial flat roofing contractor, we work on office buildings, light industrial facilities, retail spaces, warehouses, and large-scale commercial properties. Our expertise is tailored to the specific requirements of commercial buildings.

Commercial roofing has different realities than residential. Roof surfaces are larger, mechanical systems are more complex, and work must be planned around building operations. Our Montreal flat roofing specialists adapt their methods to ensure a safe and organized job site while minimizing disruption to business activities.

Elastomeric membrane maintenance

Commercial flat roof repair and re-roofing in Montreal

A commercial flat roof must deliver consistent performance across large surfaces exposed to harsh weather conditions. When the membrane reaches the end of its lifespan or shows significant wear, a full roof replacement becomes necessary. As commercial flat roofing contractors in Montreal, we replace the existing system while considering all roofing components.

Removing the existing membrane allows us to inspect the roof deck and assess the actual condition of the structure. We then evaluate the insulation and replace any damaged sections as needed. A two-ply elastomeric membrane system is installed according to industry standards, ensuring maximum protection across the entire surface.

Commercial roofs typically include numerous mechanical penetrations. Drains, HVAC units, ducts, and technical equipment require special attention. We reinforce these critical areas to deliver a watertight and high-performing flat roofing system.

New flat roof installation for commercial buildings

We install elastomeric membrane roofing systems for new construction and commercial expansions in Montreal. Every project begins with a detailed roof analysis. We work closely with general contractors, architects, and project managers to ensure smooth coordination.

Planning is a key component of our roofing process. We follow technical plans and specifications while ensuring long-term durability. Installation includes proper substrate preparation, insulation placement, and torch-applied membrane installation.

Our systems are designed to meet the needs of commercial property owners. We take into account roof loads, installed equipment, and future building requirements. At Toitures J.S.B., our long-term approach focuses on durability and reliability, helping reduce unexpected issues over time.

Elastomeric flat roofing for large commercial surfaces

A commercial flat roof must maintain performance despite climate variations and heavy precipitation. Large exposed surfaces require a reliable roofing system capable of withstanding multiple constraints.

Elastomeric membrane roofing is an excellent option for commercial buildings. Its two-ply composition offers strong durability and long-term resistance. Installed by our certified and experienced roofers, it ensures high performance for your commercial flat roof in Montreal.

As business owners ourselves, we understand the importance of a reliable roof to protect operations and avoid costly repairs.

Montreal elastomeric flat roof re-roofing

White elastomeric membrane for commercial buildings

In the Montreal area, reflective roofing membranes are often required to help reduce urban heat island effects. White elastomeric membranes meet these requirements by reflecting sunlight and improving building energy efficiency.

Dark roofing surfaces absorb significant heat, increasing indoor temperatures and cooling demands. A light-colored flat roof membrane helps reduce heat buildup and stabilize roof temperatures, improving energy efficiency, especially during the summer months.

This represents a significant advantage for any commercial building managed by a flat roofing contractor in Montreal.
