Skylight Installation
Commercial Skylights
Universal Roofs provides large-scale commercial skylight installation and renovation services for warehouses, retail centres, manufacturing facilities, and heritage building conversions across the Greater Toronto Area. From custom-fabricated ridge skylights spanning 50+ feet to multi-unit dome skylight arrays covering thousands of square feet of roof area, our team handles the complete process — structural engineering coordination, custom fabrication, precision installation, and comprehensive waterproofing integration with your existing flat roofing or steep-slope roofing system.
How Universal Roofs Delivers Large-Scale Commercial Skylight Solutions in Toronto
Large-scale commercial skylight projects represent some of the most technically complex work in the roofing industry. They combine the challenges of structural engineering, custom fabrication, weather-dependent construction scheduling, and precision waterproofing into a single project that demands expertise across multiple disciplines. Universal Roofs brings the full-service capability needed to deliver these projects safely, on schedule, and within budget. Whether you’re planning a new skylighted warehouse, converting a heritage building, or renovating an aging commercial skylight system, our team manages every aspect of the project. We also provide skylight replacement services for existing commercial skylight systems that are past their service life.
Common Challenges With Large-Scale Commercial Skylight Projects in Toronto
Large-scale commercial skylight installations involve significant structural modifications, custom engineering, and complex waterproofing requirements that go far beyond standard skylight installation. Structural steel reinforcement may be required to support the weight of large skylight assemblies and anticipated snow loads (Toronto requires designs for 1.5 kPa minimum). Custom fabrication introduces long lead times and requires precise coordination between shop drawings and field conditions. Heritage building conversions add additional layers of complexity including heritage compliance requirements, structural reinforcement of century-old buildings, and integration with existing architectural features. Throughout all of this, the building’s waterproof envelope must be maintained — especially critical during multi-week installation phases when sections of roof are open. Our experience with both large-scale skylight projects and commercial flat roofing and roof replacement gives us the integrated expertise these projects demand.
What We Deliver With Large-Scale Commercial Skylight Projects
Our large-scale skylight projects are engineered to deliver transformative results: dramatic natural daylight that reduces artificial lighting costs by 50-75%, enhanced occupant comfort and productivity (research shows 15-20% productivity improvement with natural daylight), architectural distinction that differentiates your building in the marketplace, compliance with Ontario Building Code structural and energy requirements, and a fully warranted installation that performs for 20+ years with minimal maintenance.
Our Large-Scale Commercial Skylight Solutions
We design and install four categories of large-scale commercial skylight systems. Custom ridge skylights create continuous bands of natural light along building ridgelines — ideal for warehouses and manufacturing facilities. Continuous vault skylights provide dramatic curved glass canopies for retail atriums, lobbies, and public spaces. Multi-unit dome arrays deliver distributed daylight across large flat roof areas for commercial and institutional buildings. And heritage restoration skylights replicate original architectural designs using modern, energy-efficient materials. Every project includes structural engineering coordination, custom fabrication management, comprehensive roofing integration, and detailed warranty documentation.
How Universal Roofs Approaches Large-Scale Commercial Skylight Projects
1. Assessment & Preparation
We conduct a comprehensive structural assessment of the existing building using both visual inspection and non-destructive testing methods. For steel-framed buildings, we verify connection capacities, member sizes, and load paths. For heritage buildings, we assess existing structural systems and identify reinforcement requirements. We work with licensed structural engineers to prepare detailed load calculations including dead loads (skylight self-weight), live loads (maintenance access), snow loads (1.5 kPa minimum plus drifting factors), and wind loads (based on building height and exposure category).
2. Design & Planning
Our design team works collaboratively with architects, structural engineers, and the building owner to develop skylight systems that meet both aesthetic vision and structural requirements. We prepare detailed shop drawings showing frame dimensions, glazing layouts, structural connections, and waterproofing transitions. Daylight modelling calculations optimize skylight size and placement for maximum natural light distribution throughout the interior space. All designs are reviewed against Ontario Building Code Part 3 (large buildings), Part 5 (structural), and Part 12 (energy efficiency) before fabrication begins. Visit our skylights page to learn more about our capabilities.
3. Materials Selection
We source commercial-grade skylight systems from leading manufacturers including Wasco, Bristolite, and Oldcastle BuildingEnvelope, as well as custom-fabricated assemblies from certified aluminum fabricators. All glazing is laminated safety glass (inner lite) over tempered safety glass (outer lite), rated for Toronto’s heavy snow loads and high-wind conditions. Frame systems are extruded 6063-T5 aluminum with thermal break technology (polyamide strut or pour-and-debridge) achieving frame U-values below 3.0 W/m2K. All sealant systems are two-part structural silicone rated for continuous service from -40C to +80C.
4. Installation & Craftsmanship
Our specialized crews manage large-scale skylight installation in carefully coordinated phases. We erect temporary weather protection (scaffolding and tarpaulins) to maintain the building envelope during roof opening phases. Structural steel reinforcement is installed and inspected before any roof cutting begins. Skylight frames are lifted into position using crane or hoist equipment and secured to structural supports. Glazing is installed from the exterior with proper safety measures. All roofing membrane transitions are completed by our flat roofing specialists using the same materials and techniques as the primary roof system. We coordinate with building operations to schedule phases that minimize disruption. Contact us to discuss your project timeline.
5. Quality Assurance
Every large-scale skylight project undergoes comprehensive commissioning testing: hose testing at 20 PSI at all frame joints and glazing seals, thermal imaging to verify insulation continuity and identify potential condensation zones, structural deflection measurement under representative loads, and interior air leakage testing at critical joints. We document every phase of the installation with photographs and detailed reports for warranty records, building maintenance files, and heritage compliance documentation where applicable.

Common Questions About Large-Scale Commercial Skylight Installation in Toronto
How long do large commercial skylight projects take?
Large-scale projects vary significantly based on scope, custom fabrication requirements, structural modifications, and weather conditions. A typical multi-unit dome skylight installation (10-20 units) takes 3-4 weeks on-site. Custom ridge or vault skylights may require 6-10 weeks including fabrication lead time. Heritage conversions can take 2-4 months depending on the complexity of structural reinforcement and heritage compliance requirements. We provide a detailed phase-by-phase schedule before work begins.
Are commercial skylights suitable for Toronto winters?
Absolutely. The commercial skylight systems we install include thermal break frame technology (achieving frame U-values below 3.0 W/m2K), high-performance laminated glazing with Low-E coatings and argon gas fill (centre-of-glass U-values below 1.5 W/m2K), and condensation gutters that collect and drain any interior moisture. These systems are designed and tested for Canadian climate conditions including -40C winter extremes and heavy snow loads.
What is the ROI on commercial skylights?
Commercial skylights typically deliver a 3-7 year payback through reduced artificial lighting costs, particularly in high-bay facilities that operate lighting for 10-16 hours per day. Beyond energy savings, skylights add significant value through improved tenant appeal, enhanced property differentiation, and documented productivity improvements in daylighted spaces. Multi-tenant buildings often achieve higher lease rates in skylighted areas.
Do you offer maintenance programs for commercial skylights?
Yes. We offer scheduled maintenance programs that include semi-annual seal and gasket inspection, glazing condition assessment, drainage verification, internal condensation gutter cleaning, and minor sealant repairs. Regular maintenance prevents small issues from developing into costly roof repairs and extends the service life of your skylight system to 25+ years. Contact us to set up a maintenance program.
