Commercial Skylight Installation

Summary

Commercial Skylight Installation from Sky Design Concepts engineers and builds new roof openings, distinct from replacement or repair work. Serving Phoenix, Arizona, and the Southwest since 1985, the company handles structural evaluation, permitting, and factory-certified VELUX Commercial installation as one scope, confirmed through a free on-site evaluation.

Key Takeaways

Commercial Skylight Installation cuts a brand-new opening into a roof that has never had a skylight, distinct from replacement, which swaps an existing unit, and repair, which patches a localized failure.
A large share of installs go into existing buildings, driven by IECC energy code daylighting requirements or a tenant improvement or change of use.
New openings require structural evaluation, engineered curb design, code-listed products, permitting, and NFRC-rated glazing.
Sky Design Concepts is a factory-certified VELUX Commercial installer and also installs Kingspan Light + Air, Sunoptics, Bilco, American Skylights, and Acralight systems.
System recommendations vary by building type: fiberglass panels for warehouses, tubular skylights for interior offices, and custom monumental systems for atriums and lobbies.
OSHA’s 29 CFR 1926.501 requires fall protection during the roof-cutting phase, before the curb and unit go in.
Every project starts with a free on-site evaluation to confirm structural feasibility and code requirements.

New construction and tenant improvement projects across Phoenix and the Southwest call for Commercial Skylight Installation sized to the building, not a stock unit forced onto a roof it wasn’t built for. Sky Design Concepts works from architectural plans and measured roof decks to specify, cut, and flash every opening, whether that’s a single tubular skylight in an interior office or a full daylighting system across a new warehouse floor.

Our factory-certified crews coordinate with general contractors and architects from the design stage through final install, so the finished skylight meets current wind-load and energy code requirements from day one rather than needing correction after the first monsoon season. Every installation starts with a free on-site consultation, giving building owners a clear scope before the first opening is ever cut.

What Commercial Skylight Installation Covers

Installation means a roof opening that does not exist yet gets engineered, framed, and built out into a finished skylight. That is a different project than a commercial skylight replacement, which swaps an existing unit down to its curb, and different again from a commercial skylight repair or restoration and wet sealing job, both of which work on a skylight that is already on the roof.

If a building already has a skylight and the question is whether it needs service instead of a new one, our repair vs. replace guide is the faster starting point. This page covers roofs getting a skylight for the first time, whether that is a single retrofit unit on an existing warehouse or a full daylighting plan on a new building shell.

Is This a Skylight Installation, a Replacement, or a Repair?

The three services get confused often enough that it is worth settling the question up front. The table below sorts the most common scenarios into the right service tier:

Scenario	Existing Skylight Opening?	Recommended Service	Why
Roof has never had a skylight	No	Commercial Skylight Installation	A new curb, structural opening, and flashing system all have to be engineered from scratch
New building shell in design or framing	No	Commercial Skylight Installation	Skylight openings are planned into the roof structure before the deck goes on
Warehouse adding skylights to meet a code-driven daylighting requirement	No, or only partial coverage	Commercial Skylight Installation	New openings are added to reach the required daylight zone coverage
Existing skylight is cracked, clouded, or leaking after repeated repairs	Yes	Commercial Skylight Replacement	The curb and opening already exist; only the unit itself needs to come off and go back on
Existing skylight frame is sound but the seal has weathered	Yes	Skylight Restoration & Wet Sealing	Re-seals the curb-to-frame joint without touching the glazing or cutting anything new
Existing skylight has a single, isolated leak	Yes	Commercial Skylight Repair	A patch or re-flash resolves a localized failure without a full unit swap

Still not sure which row fits a specific roof? A free on-site evaluation settles it before any work gets scoped.

Why Commercial Buildings Add Skylights Years After Construction

The new skylight installation is not only a new-construction item. A large share of the installed Sky Design Concepts handles go into buildings that have stood for years without a single skylight. Two drivers show up repeatedly:

Energy code compliance is one of them. Commercial energy codes based on the International Energy Conservation Code (IECC) require daylighting in large enclosed spaces, generally spaces over 2,500 square feet with at least 75 percent of the ceiling under a roof higher than 15 feet, covering uses like warehouses, retail floors, gymnasiums, and distribution centers.

Where that trigger applies, the code requires a minimum daylight zone under skylights rather than leaving it optional, which is why a warehouse built decades ago can suddenly need skylights added to pass a current energy review or a tenant improvement permit. Local jurisdictions adopt and amend these provisions on their own schedule, so checking the version in effect with the local building department is part of scoping any project built around this trigger.

The second driver is simpler: a tenant improvement, an expansion, or a change in use (a dark storage building becoming a retail or office space, for example) often brings daylighting into the plan for the first time. Our daylighting consulting team scopes both situations, code-driven and design-driven, before any roof gets cut.

Structural and Code Considerations for a New Roof Opening

Cutting a new opening into an existing roof is structural work, not just a product swap, and several pieces have to line up before a saw touches the deck:

Roof framing evaluation: A structural assessment confirms the roof deck and framing can carry a new opening without added reinforcement, or identifies where reinforcement is needed.
Engineered curb design: The curb has to be sized and fastened to resist the wind uplift loads that apply in the Southwest’s open desert terrain and monsoon wind gusts, not just hold the unit’s weight.
Code-listed products: Skylight assemblies used on a new opening should carry a current code-compliance evaluation report, the kind published through the International Code Council, confirming the specific glazing, curb, and fastening details meet the applicable building code.
Permitting: New roof penetrations in Phoenix go through the City of Phoenix Planning & Development Department, and most jurisdictions in our service area require a permit and, often, engineered drawings for a new opening.
Glazing performance: Selecting glazing with a known U-factor and solar heat gain coefficient, rated through the National Fenestration Rating Council, keeps a new skylight from adding more cooling load than the daylighting is worth.
Fall protection during the cut: An open roof deck before the curb and unit go in is a fall hazard under OSHA’s 29 CFR 1926.501, so guardrails or personal fall arrest systems go up before the opening is cut, not after.

Skylight Systems We Install by Building Type

The right system for a new opening depends on the building’s roof structure, the use below it, and whether daylight, ventilation, or both are the goal. The table below matches common building types to the systems installed most often for them, all part of our systems line-up:

Building Type	Recommended System(s)	Why
Warehouse / distribution center	Fiberglass & Kalwall-type, Dome/unit/polycarbonate	Wide-span diffused daylight across open floor area without hot spots
School / gymnasium	Fiberglass & Kalwall-type, Tubular skylights	Even light for large open rooms plus smaller units for hallways and locker areas
Office / retail interior	Glass skylights, Tubular skylights	Architectural clarity for lobbies, smaller footprint units for interior rooms
Atrium / lobby / monumental space	Custom & monumental skylights	Built to a specific architectural opening rather than a stock curb size
Spaces needing fresh air, not just light	Retractable & operable skylights	Adds motorized or manual ventilation alongside daylight
Manufacturing / code-required smoke control	Smoke vents & roof hatches	Vented opening required by code rather than a fixed dome
Full wall or roof section daylighting	Translucent wall & roof assemblies	Daylights an entire section rather than individual curb-mounted units
Covered walkway or entrance	Canopies & walkways	Daylit cover for connective and entrance spaces, not a roof penetration

Factory-Certified Commercial Skylight Installation

Sky Design Concepts crews carry factory certification to install VELUX Commercial systems, which means the installation follows the manufacturer’s own engineering details rather than a generalized field method, and keeps the manufacturer’s product warranty intact. We install and service systems from Kingspan Light + Air, Sunoptics, Bilco, American Skylights, and Acralight as well; see the full manufacturers list for brand-specific detail.

Skylight Installation for Warehouses, Industrial Buildings, and Schools

Application still shapes the project even once the system is chosen. Warehouse and industrial installs usually involve multiple openings sized to roof-deck spacing and engineered as a set, since a facility manager adding skylights to meet a daylighting requirement needs the whole coverage area calculated, not unit by unit. Schools and education facility installs are typically scheduled for a break or weekend, since an open roof deck and active construction are not compatible with an occupied campus.

What Affects the Cost of a Commercial Skylight Installation

Every installation is priced after a structural look at the specific roof, but the factors that move a quote up or down are consistent:

Structural modification needed: A roof deck that can take a new opening without reinforcement costs less to build out than one needing added framing.
Number and size of openings: A single retrofit unit costs less than a multi-unit installation sized to meet a code-driven daylight-zone requirement.
Engineering and permit complexity: A straightforward retrofit permit is a simpler scope than a project requiring stamped structural drawings.
System type: A stock dome or tubular unit installs faster than a custom monumental skylight or a full translucent wall assembly.
Access and roof height: Fall protection staging and material staging both factor into labor time, especially on taller industrial roofs.

A free on-site evaluation is the fastest way to get an accurate number instead of a rough range.

Our Commercial Skylight Installation Process

Every installation follows the same structured path, from first site visit to final inspection, so building owners and general contractors know exactly what to expect at each stage. Here’s how a typical project moves from planning to completion.

Structural evaluation: A technician and, where required, a structural engineer assess the roof deck and framing to confirm it can support a new opening.
System and glazing selection: Based on the building’s use, code requirements, and daylighting goals, we recommend a system and manufacturer, with NFRC-rated performance data where energy use is a factor.
Permitting and engineering: Sky Design Concepts prepares the permit package, including engineered drawings where the local building department requires them, and submits it before mobilization.
Framing and curb construction: Crews stage fall protection, cut the new opening, and build or set the engineered curb to the manufacturer’s specifications.
Unit installation and flashing: The skylight goes in, flashed and sealed to the curb and surrounding roof membrane.
Final inspection and cleanup: The finished opening is weather-tested, any required city inspection is scheduled, and the site is cleared of debris.

Frequently Asked Questions

How is installation different from replacement?

Installation cuts a brand-new opening into a roof that has never had a skylight; replacement swaps the unit on a curb and opening that already exists. The comparison table above sorts out which applies to a specific roof.

Do I need a structural engineer to add a skylight to an existing building?

Often, yes, especially for larger openings or roofs carrying significant existing load. Our structural evaluation during the on-site visit identifies whether stamped engineering is needed before a permit can be submitted.

Can I be required to add skylights to an existing building?

In some cases. Commercial energy codes based on the IECC require daylighting in certain large enclosed spaces, and a tenant improvement, change of use, or energy review can trigger that requirement on a building that has never had skylights. Our daylighting consulting team can confirm whether a specific project falls under that trigger.

Do I need a permit for a new commercial skylight installation?

In nearly all cases, yes. The City of Phoenix Planning & Development Department requires a permit, and often engineered drawings, for a new roof penetration; Sky Design Concepts handles the application as part of the project scope.

Which skylight brands do you install?

We are factory-certified for VELUX Commercial and also install and service Kingspan Light + Air, Sunoptics, Bilco, American Skylights, and Acralight systems. See our full manufacturers list.

What states are Sky Design Concepts licensed to work in?

Arizona, Nevada, and New Mexico. We also travel to West Texas markets as a service-area contractor, without holding a Texas contractor license there.

How long does a new skylight installation take?

A single retrofit unit on an existing roof is typically a multi-day job once the structural opening and curb work are factored in. Multi-unit warehouse installs or new-construction projects run longer and are scheduled around structural engineering and permit timelines.
