Most are flat or low-slope membrane roofs under a manufacturer’s warranty, the building below is full of people or product, and every opening becomes a fall hazard the moment it is cut. A commercial skylight install has to respect all three. That means surveying the roof and structure, producing shop drawings, building insulated curbs, tying into the membrane to the roofing manufacturer’s detail, screening every opening and working in phases so the business keeps running. We do all of it with our own WSIB crews and $5M in commercial general liability. ## The 5 Commercial Building Types We Install Skylights In Across GTA Over 20 years the work has settled into five building types, each with its own priorities. ### 1\. Offices and Corporate Lobbies Daylight in lobbies and open-plan floors is a leasing feature. Our Vaughan Metropolitan Centre office tower lobby atrium had 14 panels, installed in 2023 around tenant hours. ### 2\. Retail and Showrooms Natural light makes merchandise look right. We schedule cutting before opening and protect fixtures below with sealed enclosures. ### 3\. Warehouses and Distribution Centres Per-bay skylights cut daytime lighting in racking aisles. Our Markham tech corridor 12-bay install ran $84,000 over two weeks, phased so racking stayed in use. ### 4\. Restaurants and Hospitality Atrium skylights over dining rooms. Our Oakville Lakeshore corridor restaurant atrium came in at $28,500 over three days, worked around lunch and dinner service. ### 5\. Schools and Medical Buildings Quiet, safe glass over occupied rooms. Laminated interior glass, screens and after-hours work are standard. ### Industrial and Manufacturing Older plants with sawtooth or monitor roofs often have failing wired glass. We replace or convert them to modern units with screens. ## Residential and Multi-Residential Projects for Commercial Clients Property managers and developers also bring us residential-scale work in commercial settings. ### Condo Amenity Spaces Our King West condo developer retrofit covered 12 units in 2024, with board approvals, COI and tenant notices handled. ### Rental and Mixed-Use Buildings Top-floor apartments over retail along Queen, Danforth and Roncesvalles often have tired skylights. We coordinate access with tenants. ### Seniors’ Residences Common rooms and corridors benefit most. We schedule quiet work hours and use laminated glass. ### Townhouse Complexes Multiple identical units mean we can standardize models and flashing and finish a block efficiently. ## Specialty Commercial Systems ### Velux Dynamic Dome and Unit Domes Fast-fit domes for flat roofs, with good thermal performance and screen options. ### Ridge and Pyramid Skylights Engineered systems for lobbies and atria, built from shop drawings. See custom skylight design [/custom-skylight-design-installation/ →](/custom-skylight-design-installation/) . ### Barrel Vaults Curved glazing for corridors and malls, with thermally broken framing. ### Smoke Vent Skylights ULC-S527 listed units where the building code or fire plan calls for heat and smoke venting. ### Walkable and Flat Glass Fakro DXW and similar units on roof terraces and podiums. See flat roof skylight installation [/flat-roof-skylight-installation/ →](/flat-roof-skylight-installation/) . ## Materials and Systems We Specify | Component | Options | Notes | | --- | --- | --- | | Units | Velux Dynamic Dome, curb-mount glass, ridge, pyramid, barrel vault | Picked by span, use and budget | | Glazing | Laminated, tempered Low-E, polycarbonate | Laminated over occupied spaces | | Curbs | Insulated wood or steel curbs | Raised above snow and ponding | | Membrane tie-in | TPO, EPDM, SBS modified bitumen | To the roofing manufacturer’s detail | | Safety | Fall-protection screens to MOL standard | Installed the day the opening is cut | ## Our Commercial Expertise Commercial skylight work fails in predictable ways: a membrane tie-in nobody warranties, an opening left unprotected, a contractor who disappears before closeout. We avoid all three by confirming the warranty holder before we cut, screening openings the same day and handing over a full closeout package with photos, product data and warranty documents. Our crews are trained for Ontario working-at-heights requirements, and we never subcontract. The people on your roof are our employees. ## What Actually Stops Property Managers From Adding Skylights ### “It will void our roof warranty.” In our opinion, that only happens when someone improvises the tie-in. We detail to the roofing manufacturer’s specs and coordinate with the roofer of record when needed. ### “Tenants will complain.” Phasing, after-hours cutting and sealed interior protection keep complaints rare. Our King West retrofit had none. ### “Liability is a headache.” $5M CGL, $2M property damage, full WSIB, COI and clearance letters before day one. ### “We can’t get a straight number.” Itemized proposals with a unit schedule. Our commercial ranges are on the pricing page [/pricing/ →](/pricing/) . ## Commercial Installation Timeline ### Survey and Proposal (Week 1 to 2) Roof walk, structure check, shop drawings and itemized proposal. ### Approvals and Fabrication (Weeks 2 to 8) Permits, engineering sign-off and fabrication for custom systems. ### Phased Install One day for single units, one to three weeks for multi-bay or atrium projects. ### Closeout Photos, warranties, as-built drawing and a final roof walk with your manager. ## Commercial Skylight Cost in Toronto: What Drives the Price ### System Type Unit domes cost least per square foot; engineered atria cost most. ### Opening Size and Structure Large spans need engineering, steel or LVL framing and sometimes a crane. ### Membrane Type SBS torch-down tie-ins take more care and time than TPO or EPDM. ### Safety and Screens Fall-protection screens are part of every commercial quote. ### Phasing and After-Hours Work Night and weekend work carries a premium, listed on its own line. ### Access and Lifting Cranes, boom lifts and street occupancy permits add cost on tight downtown sites. ## Commercial Skylight Installation vs Replacement vs Repair: Which Service You Need New openings are installation. Failing units in existing openings are commercial skylight replacement [/commercial-skylight-replacement/ →](/commercial-skylight-replacement/) , often best timed with a re-roof. A single leaking unit may only need leak repair [/skylight-leak-repair/ →](/skylight-leak-repair/) . ## Fixed, Venting or Solar: Choosing Your Skylight Type Most commercial work uses **fixed** units and domes. **Venting** and smoke-vent units suit spaces needing airflow or code-required venting. **Solar** and smart-controlled units fit offices and clinics where staff want remote control without new wiring runs. ## Commercial Skylight Timeline in Toronto: What to Expect Week-by-Week Expect one to two weeks for survey and proposal, two to eight weeks for approvals and fabrication, then one day to three weeks on site depending on scope. Closeout documents follow within a week of completion. ## Why GTA Property Managers Keep Our Number In-house crews, real insurance, clean paperwork and a lifetime leak-free warranty on our flashing. It is pretty simple, everytime. Field-Tested Workflow ## How Our Commercial Installation Process Works, 5 Steps The same five steps on every job, whether it is one skylight over a Leaside bathroom or a warehouse full of bays. 1. 1 ### Site Walk + Roof Survey We walk the roof with your facility manager, note the membrane type and warranty holder, check the structure and plan access and staging. 2. 2 ### Shop Drawings + Proposal Itemized CAD proposal with unit schedule, shop drawings, phasing plan and COI, ready for your GC, architect or board. 3. 3 ### Permits Without Padding Building permits at actual cost on their own line. Some installers over-charge for permits thinking owners wont check other quotes. Property managers always check, and so should you. 4. 4 ### Phased Install + QA Bays or panels installed in phases, screened the same day they are cut, tied into the membrane and signed off by the crew lead against our founder's commercial checklist. 5. 5 ### Closeout Package Photos, warranty documents, product data and an as-built drawing. Then your tenants get to enjoy a much brighter building.

Straight Answers ## Commercial Installation FAQ: 12 Questions Toronto Clients Ask ### How much does commercial skylight installation cost in Toronto? An office or retail single skylight runs $8,000 to $18,000 CAD, industrial warehouse skylights $6,500 to $14,000 per bay and multi-unit atria $25,000 to $120,000. Proposals itemize units, labour, membrane tie-in, screens, permits and any engineering. ### Will installing skylights void our roof warranty? Not if the membrane tie-in is done to the roofing manufacturer's details. We confirm who holds the warranty, coordinate with the roofer of record where required and tie into TPO, EPDM or SBS by the book. ### What insurance do you carry? $5M commercial general liability, $2M property damage and full WSIB coverage on every crew member. COI and WSIB clearance letters are supplied before mobilization. ### Can you work while our building is occupied? Yes. We phase work, schedule noisy cutting before opening or after hours, keep screens on every opening and protect the interior below. Our Lakeshore restaurant atrium was completed around service. ### Do you provide shop drawings and engineering? Yes. Shop drawings are standard on commercial work, and we bring in a structural engineer for atria, large openings and any structural change. ### Do skylights need fall protection on commercial roofs? Ontario working-at-heights rules and MOL requirements mean openings must be protected. We install fall-protection screens on commercial units as standard and our crews are trained for working at heights. ### Which commercial skylight systems do you install? Unit domes such as the Velux Dynamic Dome, curb-mount glass units, ridge and pyramid systems, barrel vaults and multi-panel atria, plus ULC-S527 smoke vent units where code calls for them. ### How long does a commercial install take? A single office skylight is usually one to two days. Warehouse bays run in phases over one to three weeks. Atria take one to two weeks on site after fabrication. ### Can skylights lower our energy costs? Daylight can reduce daytime lighting load in warehouses, retail and schools. Savings depend on hours, layout and controls, so we do not promise a number, but facility managers usually notice the lighting bill. ### Do you work for general contractors and architects? Often. We price from drawings, attend site meetings, coordinate with the roofer and other trades and deliver closeout documents your GC needs. ### Can you replace skylights during a re-roof? Yes, and it is the smartest time. Sharing mobilization with the re-roof saves money. See our commercial skylight replacement service. ### Do you handle schools and medical buildings? Yes. We plan around occupancy, use laminated glass over occupied spaces and provide method statements for facility managers. Still have a question? Talk to a crew lead, not a call centre.
