Why Choose Commercial
Commercial roofing requires a completely different skill set and material knowledge than residential work. A leaking roof in a commercial building doesn't just damage the structure—it disrupts your operations, damages inventory, and creates liability hazards for employees and customers. Calgary Roofing Pro provides robust, industrial-strength flat roofing solutions for warehouses, retail plazas, multi-family stratas, and office buildings across Calgary.
**Specialized Flat Roof Systems (SBS Torch-On)**
Our primary expertise lies in 2-ply SBS (Styrene-Butadiene-Styrene) Modified Bitumen Torch-On systems. This is the gold standard for Alberta's commercial roofs. Unlike single-ply membranes that can become brittle in extreme cold, our multi-ply rubberized asphalt systems remain flexible and watertight even in -40°C temperatures.
**Maintenance & Asset Management**
We don't just install new roofs; we help you manage your existing assets. Our commercial maintenance programs include semi-annual inspections, drain cleaning, and proactive repairs to extend the lifespan of your roof and prevent costly premature replacement.
Our Process
How We Work
Professional, transparent, and efficient. Here is what you can expect when you hire us.
1. Core Analysis
We perform core cuts to determine the makeup of the existing roof assembly and identify trapped moisture in the insulation.

3. Membrane Installation
We install the base sheet (mechanically fastened or adhered) followed by the granular cap sheet using precision heat welding.
4. Flashing & Metal Work
Parapet caps and scuppers are custom-fabricated and installed to ensure water is directed efficiently to the drains.

Professional Commercial Flat Roofing Solutions in Calgary
Managing a commercial property involves protecting valuable assets, ensuring employee safety, and maintaining uninterrupted business operations. A failing or leaking commercial roof can cause devastating damage to inventory and lead to costly operational downtime. Calgary Roofing Pro is the premier provider of commercial flat roofing in Calgary, specializing in robust, industrial-strength flat roof systems for warehouses, retail plazas, office buildings, and multi-family strata complexes.
Commercial roofing requires specialized expertise and highly durable materials. The gold standard for Alberta's harsh climate is the 2-ply SBS (Styrene-Butadiene-Styrene) Modified Bitumen Torch-On system. Unlike older tar and gravel roofs or single-ply membranes that can become brittle and crack in -40°C weather, SBS torch-on systems utilize a rubberized asphalt compound. This allows the roofing membrane to remain incredibly flexible, expanding and contracting with Calgary's massive temperature swings without compromising the watertight seal. While we also offer TPO and EPDM single-ply options for specific building requirements, the 2-ply SBS system remains our top recommendation for long-term reliability.
Preventative Commercial Roof Maintenance
The lifespan of a commercial flat roof is heavily dependent on proactive maintenance. We help property managers avoid premature, expensive roof replacements through our comprehensive roof asset management programs. Our commercial maintenance includes bi-annual inspections (Spring and Fall), debris removal, drain and scupper cleaning, and rapid patching of emerging blisters or separated seams.
We also perform deep core-cut analysis to determine the exact composition of your existing roof assembly and identify trapped moisture within the insulation layers. This allows us to provide targeted repairs or plan cost-effective retrofits tailored exactly to your building's needs. Trust our fully insured, OHS-compliant crews to handle your commercial roofing projects safely and efficiently.
