    Commercial Roof Installation & Replacement Service

    When your commercial roof in Calgary or Edmonton reaches the end of its life—showing widespread leaks, membrane failure, insulation saturation, structural concerns, or energy inefficiency—professional installation or replacement is essential. Alberta's extreme climate, with sub-zero winters, heavy snow loads up to 100+ kg/m², frequent hail, Chinook winds, rapid freeze-thaw cycles, and intense summer UV, demands high-performance systems that ensure long-term waterproofing, energy efficiency, and code compliance.

    Our experienced team handles complete tear-offs, deck repairs, new installations, and overlays using premium materials suited to flat/low-slope roofs common in warehouses, offices, retail, and industrial buildings. We minimize downtime with phased work, proper drainage design, insulation upgrades, and warranties up to 30+ years, protecting your investment, reducing utility costs, preventing interior damage, and enhancing building value across both cities.

Our tailored solutions deliver maximum ROI and reliability for diverse Alberta properties.

    Initial Consultation & Roof Assessment

    We start with a detailed consultation to review your building’s history, current roof issues, energy concerns, and business needs in Calgary or Edmonton. Our team conducts a thorough on-site inspection, including core sampling, moisture scans, and structural evaluation to determine if full replacement, overlay, or targeted upgrades are best. 

    We discuss options, timelines, budgets, and minimal-disruption strategies. This phase ensures an accurate scope, identifies underlying problems like deck rot or poor insulation from Alberta’s climate, and sets realistic expectations for a successful project.

    Planning, Permits & Material Selection

    After assessment, we develop a customized plan detailing scope, phasing to limit business impact, safety measures, and waste management. We handle necessary permits from local authorities and select premium materials optimized for Alberta’s harsh conditions—considering snow loads, hail resistance, UV protection, and energy codes. 

    We provide detailed quotes, timelines, and 3D mockups if needed. Coordination with your schedule ensures work occurs during optimal weather windows (spring-fall) while prioritizing safety and compliance throughout the installation or replacement process.

    Demolition, Preparation & Installation

    The core phase begins with safe tear-off of the old roof (or overlay prep), debris removal, and disposal. We repair or replace damaged decking, install new vapor barriers, high-R insulation for energy efficiency, and tapered systems for proper drainage to combat ponding and ice damming. 

    New roofing—whether TPO, EPDM, modified bitumen, or metal—is installed using manufacturer-approved methods: heat-welding seams, torch-applying, or mechanically fastening. Quality checks at every step ensure watertight performance suited to Calgary and Edmonton extremes, with minimal disruption via phased zoning.

    Final Inspection, Testing & Handover

    Upon completion, we perform rigorous testing—flood tests, infrared scans, or electronic leak detection—to verify waterproof integrity. A detailed walkthrough with you includes photos, as-built documentation, maintenance guides, and warranty registration. 

    We clean the site thoroughly and provide training on care. Ongoing support includes follow-up visits and optional maintenance plans to monitor performance against Alberta weather. This ensures your new commercial roof delivers long-term reliability, energy savings, and protection for your Calgary or Edmonton property.

    Different Types of Commercial Roof Installation & Replacement Services

    Complete removal of the existing roof down to the deck allows inspection and repair of structural issues, rotten wood, or poor insulation caused by years of moisture in Alberta winters. New systems—insulation, vapor barriers, membranes—are installed fresh for optimal performance. Ideal when old roofs have multiple layers, severe damage, or energy inefficiency; provides maximum longevity (25-40+ years) and warranty strength in Calgary and Edmonton.

    For structurally sound decks with one existing layer, overlays add new insulation and membrane without full tear-off, reducing costs, waste, and downtime. Common for TPO, EPDM, or modified bitumen over aged roofs. Suited to Alberta’s climate when underlying issues are minimal; enhances insulation R-value, seals leaks, and extends life cost-effectively while maintaining building operations.

    Standing seam or architectural metal systems offer sloped or low-slope options with excellent snow-shedding, hail resistance, and 40-70+ year lifespans. Ideal for industrial or retail buildings in windy/hail-prone Alberta. Installation includes underlayment, clips/fasteners, and sealants for wind uplift resistance; provides durability, low maintenance, and energy reflectivity against extreme temperature swings.

    Includes green/vegetated roofs, solar-integrated, or hybrid (e.g., SBS torch-on with reflective coatings) for unique needs like sustainability or high-traffic areas. Tailored to Alberta’s demands with enhanced drainage, root barriers, or impact resistance. These installations upgrade energy performance, support LEED goals, and handle freeze-thaw while offering customized solutions for modern commercial properties in Calgary and Edmonton.

    Best Materials for Commercial Roof Installation & Replacement in Alberta

    Choosing the right materials for installation or replacement in Calgary and Edmonton is critical to withstand extreme cold, heavy snow loads, hail impacts, wind, and freeze-thaw cycles. Top performers include flexible single-ply membranes, modified bitumen, and metal systems that offer durability, energy efficiency, UV resistance, and long lifespans while ensuring proper drainage and insulation upgrades for flat/low-slope commercial roofs.

    TPO (Thermoplastic Polyolefin) Membranes

    TPO is a leading single-ply choice for new installations and replacements in Calgary and Edmonton due to heat-welded seams for superior watertight performance, high solar reflectivity reducing cooling costs by 20-30%, and flexibility in sub-zero temperatures without cracking. It resists chemicals, punctures, and UV degradation, offering 20-30+ year lifespans. Ideal for large flat commercial roofs, it provides energy savings and easy maintenance against Alberta’s hail and thermal stress.

    EPDM (Ethylene Propylene Diene Monomer) Rubber Membranes

    EPDM excels in extreme cold, remaining flexible to -40°C and resisting hail, ozone, and UV for 30+ year durability. Fully adhered or ballasted installations ensure strong waterproofing on flat/low-slope roofs common in Alberta warehouses and offices. It handles freeze-thaw without shrinking/cracking, offers proven performance in heavy snow, and provides cost-effective, low-maintenance protection with excellent energy retention.

    Modified Bitumen (SBS/APP Torch-On or Self-Adhered)

    SBS modified bitumen systems deliver multi-layer toughness with polymer-modified asphalt for superior flexibility and adhesion in cold climates. Torch-on application creates seamless, waterproof membranes resistant to punctures, hail, and ponding. Popular for Calgary and Edmonton commercial replacements, it offers 20-30+ year lifespans, strong impact resistance, and compatibility with existing systems for durable, high-performance flat roofs.

    PVC (Polyvinyl Chloride) Membranes

    PVC provides exceptional chemical/puncture resistance, heat-welded seams, and reflectivity for energy efficiency in Alberta’s variable weather. It stays flexible in harsh winters, resists grease/oils (ideal for restaurants), and handles UV/hail well with 20-30+ year durability. Great for flat commercial installations requiring high foot traffic tolerance and long-term reliability against freeze-thaw and wind.

    Standing Seam Metal Roofing Systems

    Premium standing seam metal (steel/aluminum with coatings) offers unmatched longevity (40-70+ years), snow-shedding slopes, and superior wind/hail resistance for Alberta extremes. Concealed fasteners prevent leaks; reflective finishes cut energy costs. Ideal for industrial or architectural commercial replacements, it provides low maintenance, structural strength under snow loads, and timeless durability in Calgary and Edmonton.
