Commercial Roofing Built for Calgary
Commercial roofing needs differ fundamentally from residential. Flat and low-slope roofs — the standard on retail plazas, office buildings, and warehouses — require purpose-built membrane systems that manage standing water, accommodate rooftop equipment, and hold up under the foot traffic of maintenance crews. The scale is larger, the consequences of failure are greater, and business continuity is always on the line.
Calgary's climate is particularly demanding for flat commercial roofs. Rapid freeze-thaw cycles in spring and fall stress seams and flashings, heavy spring snowmelt puts drainage systems to the test, and summer hailstorms can puncture single-ply membranes. A well-designed commercial roof accounts for all of these conditions — with proper slope-to-drain, reinforced membrane at penetrations, and robust edge and parapet detailing.
King's Land approaches every commercial project with a focus on minimal business disruption and long-term performance. We stage work to keep your operations running, communicate clearly at every phase, and offer structured preventive maintenance programs so small issues are caught before they become costly emergencies. Our goal is a roof that performs reliably for decades — not just until the warranty card is filed.
Commercial Roofing Systems We Install
TPO Membrane
Thermoplastic polyolefin single-ply membrane — energy-efficient, UV-resistant, and heat-welded at seams for a watertight bond. The leading choice for modern flat commercial roofs.
Modified Bitumen
Multi-layer asphalt-based system reinforced with polyester or fibreglass mats. Excellent durability and resistance to foot traffic, ideal for roofs with heavy mechanical equipment.
Built-Up Roofing (BUR)
Multiple layers of bitumen and reinforcing ply sheets topped with aggregate or a cap sheet. A proven, long-lasting system with outstanding resistance to wear and weathering.
Roof Coatings & Restoration
Extend the life of an existing roof without full replacement. Silicone and acrylic coatings restore waterproofing, improve reflectivity, and can add 10+ years to a sound substrate.
How We Install Your Commercial Roof
Building Assessment
We inspect the existing roof system, substrate condition, drainage, penetrations, and flashing details. We document everything with photos and measurements to build an accurate scope of work.
System Selection
Based on your building's use, budget, and long-term goals, we recommend the most suitable roofing system. We walk you through product options, warranty tiers, and phasing plans before any work begins.
Professional Installation
Our crew works to a coordinated schedule designed to minimize business disruption. All membrane seams, penetrations, and flashings are installed to manufacturer specifications and inspected at key stages.
Final Inspection & Warranty
A thorough walkthrough is completed with the building manager. All warranty documents are provided in writing. We schedule the first maintenance visit and establish your ongoing care program.
