Commercial roofing demands a different level of expertise, planning, and execution than residential work. Larger surface areas, complex drainage systems, rooftop equipment penetrations, and the need to minimize business disruption all require a contractor with the right experience and systems.
Top Choice Roofing has completed commercial projects for retail plazas, office buildings, warehouses, multi-unit residential buildings, and industrial facilities across Toronto and the surrounding region. We work with the full range of commercial roofing systems — TPO and EPDM flat membranes, standing seam and exposed fastener metal, and commercial-grade asphalt shingles for low-slope applications.
Every commercial project begins with a detailed site assessment, load calculations, and a written scope of work. We coordinate with property managers, building owners, and tenants to schedule work with minimal disruption, and all our commercial work meets Ontario Building Code requirements and manufacturer specifications.
We offer the right system for every commercial application — from low-slope flat roofs to steep-slope metal and shingle systems.
Thermoplastic polyolefin (TPO) is the leading choice for commercial flat roofs — energy efficient, UV-resistant, and highly durable in Canadian climates. Ideal for retail, office, and warehouse buildings.
Ethylene propylene diene monomer (EPDM) offers outstanding flexibility and weather resistance, particularly in extreme cold. A proven system for low-slope commercial applications with 20+ year lifespans.
Two-ply modified bitumen systems offer excellent puncture resistance and redundancy. A reliable choice for high-traffic flat roofs and buildings with rooftop HVAC equipment.
Standing seam and R-panel metal roofing for warehouses, industrial facilities, and commercial buildings. Exceptionally durable, low-maintenance, and available in a wide range of profiles and finishes.
Complete roofing solutions for townhome complexes, condominiums, and multi-unit residential buildings. We work efficiently on large-scale projects with coordinated scheduling and site management.
Emergency and planned repairs for all commercial roofing systems. We respond quickly to leaks and damage to minimize business interruption, and provide detailed condition reports for maintenance planning.

Common questions from property managers, building owners, and business operators.
Timeline depends on the size of the building, the system being installed, and weather conditions. A small retail building (under 5,000 sq ft) may take 2–4 days. Larger warehouses or multi-unit complexes can take 1–3 weeks. We provide a detailed project schedule before work begins and coordinate with your operations team to minimize disruption.
Yes — this is a standard part of our commercial process. We can schedule work in sections, start early in the morning, or work during off-hours and weekends when needed. We'll discuss your operational requirements during the planning phase and build the schedule around your needs.
The right system depends on several factors: the slope of your roof, the amount of rooftop foot traffic, your budget, and the climate exposure of the building. TPO is currently the most popular for energy efficiency and cost. EPDM excels in extreme cold. Modified bitumen is ideal for high-traffic roofs. We'll recommend the best fit after assessing your building.
Yes. A proactive maintenance program is the most cost-effective way to extend the life of a commercial roof. We offer scheduled bi-annual inspections, minor repair programs, and written condition reports that property managers can use for capital planning. Ask us about our commercial maintenance packages during your estimate.
Yes. Top Choice Roofing holds all required Ontario contractor licenses and carries commercial general liability insurance and WSIB coverage.
