VELUX Commercial Skylights: Factory-Certified Installation and Replacement

Summary

VELUX Commercial Skylights, including the Dynamic Dome, Modular Skylights, Sun Tunnels, and structural systems, are installed by Sky Design Concepts, a factory-certified installer in Phoenix, Arizona. The company diagnoses curb seal failure, cracked glazing, and venting issues before recommending repair, restoration, or replacement.

Key Takeaways

Sky Design Concepts is a factory-certified VELUX Commercial installer serving Phoenix, Arizona, and the Southwest.
VELUX Commercial makes four product families: Dynamic Dome unit skylights, VELUX Modular Skylights (VMS), Sun Tunnel tubular skylights, and structural skylights.
The Dynamic Dome uses a dry installation method with no caulk or curb tape, designed to capture more daylight early and late in the day.
VELUX Modular Skylights ship prefabricated, so no glazing happens on the roof, shortening exposure time during installation.
Common failure signs include water stains, yellowed or hazed domes, glazing cracks, condensation between layers, and failed venting operators.
Factory certification means the manufacturer has qualified the installer to meet its warranty-backed installation specifications, separate from state contractor licensing.
Sky Design Concepts also represents Kingspan Light + Air, Sunoptics, and Bilco, giving building owners a product choice rather than a single house brand.

Factory certification matters because the install details decide how long a skylight stays watertight. Sky Design Concepts is a factory-certified VELUX Commercial installer across Phoenix and the Southwest, supplying modular skylights and domes, including the Dynamic Dome and traditional dome lines, for flat and low-slope commercial roofs.

Every VELUX unit we set follows the manufacturer’s instructions on curb height, flashing laps, sealant, and glazing gasket, and we inspect those same points when we service one. Arizona’s heat cycles and UV exposure wear on seals and gaskets before they wear on the glazing itself, so even a VELUX unit that looks sound from the roof can still leak at the curb. We also coordinate with the roofing contractor so the skylight flashing ties into the roof membrane without gaps.

What VELUX Commercial Makes

VELUX Commercial skylights are daylighting products built for commercial roofs. If you manage a warehouse, school, clinic, or retail center in Arizona, a VELUX skylight can replace worn glazing, add daylight to a dark floor plate, or add roof ventilation where the building needs it. VELUX Commercial makes unit skylights, prefabricated modular skylights, tubular skylights, and structural skylights, manufactured in Greenwood, South Carolina, and sold through an installer network.

Sky Design Concepts is one of those installers, offering the full range of commercial skylight services, including installation, with VELUX Commercial as one of the manufacturers we represent alongside Kingspan Light + Air, Sunoptics, and Bilco. Sunoptics prismatic skylights sit under the VELUX Commercial name, so a project that calls for prismatic glazing stays with one manufacturer and one installer. Our work is commercial-only, with every crew, quote, and schedule built around commercial roofs.

Daylighting design matters as much as the product. The Whole Building Design Guide’s daylighting resource explains how skylight placement, glazing, and electric lighting controls work together, and our evaluations follow the same logic: we look at roof openings, interior light levels, and glare before we spec a unit.

VELUX Commercial Skylights We Install

We install four VELUX Commercial skylight families. Each fits a different roof, budget, and ventilation needs. You can compare every skylight type we install on our commercial skylight systems page.

Dynamic Dome Unit Skylights

The Dynamic Dome is a unit skylight built for warehouse and big box roofs. VELUX designed the dome profile to capture more daylight early in the morning and late in the afternoon, and its dry installation method uses no caulk or curb tape.

We replace failed domes by measuring the existing curb, matching the new dome to it, and replacing the curb when it is cracked, rotted, or out of square. See our dome, unit, and polycarbonate skylight page for the full range of dome options.

VELUX Modular Skylights (VMS)

VELUX Modular Skylights ship as prefabricated systems, which means installers glaze nothing on the roof. That shortens exposure time on an open roof, and the system installs in a wider range of weather than site-glazed assemblies.

VMS comes in fixed and venting versions that look the same when closed. If your building needs roof ventilation, read about our retractable and operable skylights. If it needs a UL-listed smoke vent or roof hatch, see smoke vents and roof hatches.

VELUX Sun Tunnel Skylights

Sun Tunnel units pipe daylight through a roof into a small interior space, and VELUX offers them in curb-mounted and self-flashed dome models. We cover this category in more detail on our tubular skylights page.

Structural and Custom Skylights

VELUX Commercial also builds structural skylights, including continuous vault, pyramid, and ridge systems. These are engineered to the building, so we work from the architect’s or owner’s drawings and coordinate dimensions, loads, and flashing with the manufacturer. For projects outside standard sizes, see our custom and monumental skylights page.

What Factory-Certified Means for Your Roof

A factory-certified installer is an installer the manufacturer has qualified to install its products. For a building owner, the practical result is that the person on your roof installs the skylight the way the manufacturer’s instructions specify.

That matters because manufacturers write product warranties around their own installation requirements. Ask any contractor you hire for the warranty document before you sign, and compare what it says about installer qualification. Ask us for the warranty terms that apply to your project.

Licensing is a separate check from certification. Before you hire any Arizona contractor, confirm the license on the Arizona Registrar of Contractors license search.

Certification does not replace a roof inspection. We still check the roof deck, the curb, the flashing, and the roofing membrane around each opening, because a new skylight installed on a failed curb leaks regardless of the product.

Signs You Need VELUX Skylight Replacement or Repair Service

Most skylight failures start at the glazing or at the curb. Arizona sun and heat age acrylic, polycarbonate, and sealants faster than most climates, so a skylight installed 15 years ago in Phoenix has seen heavy UV exposure.

Look for these signs on your roof or ceiling:

Water stains or drips below a skylight, which usually point to a failed curb seal, cracked glazing, or open flashing.
Yellowed or hazed domes, which reduce light transmission and mean the glazing has reached the end of its service life.
Cracks and crazing in acrylic or polycarbonate glazing, often visible as a web of fine lines.
Condensation between glazing layers, a sign of a failed seal.
Venting skylights that stick or will not close, which indicates operator or gasket failure.
Torn or dried-out curb flashing and sealant around the frame.
Visible light loss in the building, where staff have switched on electric lights that used to stay off during the day.

If you see one of these, you do not always need a full replacement. Our skylight restoration and wet sealing service fixes failed seals and flashing on skylights that are otherwise sound, and our commercial skylight repair crews handle active leaks. Our guide on repair, restore, or replace explains how we decide. When glazing has reached the end of its life, we move to commercial skylight replacement.

Skylights also create a fall hazard on roofs. OSHA’s fall protection rule for construction covers falls through holes, including skylights, from 6 feet or more. We install skylight guards and fall protection on new and existing openings.

VELUX Commercial Skylight Installation Checklist: What We Inspect on Every Roof

A new skylight performs only as well as the roof opening beneath it. This checklist shows what our crew inspects and why each item matters before and after we install a VELUX unit.

Inspection point	What we check	Why it matters
Roof deck around the opening	Deck condition, moisture damage, and structural support	A weak or wet deck cannot hold a curb or frame securely
Curb condition and dimensions	Cracks, rot, squareness, and exact size	The new dome or module must match the curb, and a damaged curb leaks
Flashing and membrane tie-in	Flashing, sealant, and the roofing membrane at the curb	Most skylight leaks start where the skylight meets the roof
Glazing and product match	Glazing type, size, and the VELUX product specified	The unit must fit the building’s daylight, ventilation, and structural needs
Fall protection	Guards or screens on new and existing openings	Skylights are fall hazards, and our skylight fall protection and guards service addresses this
Water-tightness at close-out	Seals, fasteners, and flashing on the finished installation	We confirm the opening is sealed before we leave the roof

How We Install VELUX Commercial Skylights

Every project starts with a free on-site evaluation and ends with a documented close-out.

Evaluate the roof: We inspect each skylight, curb, and flashing detail, photograph defects, and tell you whether the right move is repair, restoration, or replacement.
Measure and specify: We measure existing curbs and roof openings, confirm sizes and glazing, and select the VELUX Commercial product that fits the building and your lighting goals.
Quote and order: You receive a written scope. We order the skylights from VELUX Commercial and confirm the delivery schedule with you.
Install: Our factory-certified crew removes the old units, repairs or replaces curbs, installs the new skylights to manufacturer instructions, and flashes and seals each opening.
Inspect and close out: We check each installation for water-tightness and review the work with you.

Frequently Asked Questions

Is Sky Design Concepts a factory-certified VELUX Commercial installer?

Yes. Sky Design Concepts is a factory-certified VELUX Commercial installer based in Phoenix, Arizona. We install VELUX skylights on commercial roofs in Arizona, Nevada, and New Mexico.

What VELUX Commercial skylights does Sky Design Concepts install?

We install VELUX Dynamic Dome unit skylights, VELUX Modular Skylights, VELUX Sun Tunnel tubular skylights, and structural skylight systems. The right product depends on your roof type, the amount of daylight you need, and whether the building needs ventilation. Our free evaluation settles the choice.

Can you replace a VELUX dome without replacing the curb?

Sometimes. We measure the existing curb first and reuse it when it is sound, square, and watertight. When the curb is cracked, rotted, or damaged, we replace it, because a new dome on a failed curb leaks.

What is the difference between a Dynamic Dome and a VELUX Modular Skylight?

A Dynamic Dome is a unit skylight that sits on a curb, and it suits warehouses and big box roofs. A VELUX Modular Skylight is a prefabricated system that arrives assembled, comes in fixed and venting versions, and suits buildings that need ventilation or a larger glazed area, such as schools and corridors. We compare both during the evaluation.

Do VELUX Modular Skylights open for ventilation?

Yes. VELUX offers modular skylights in both fixed and venting versions, and the two look identical when closed. If you need a smoke vent for code compliance, see our smoke vents and roof hatches page.

Does Sky Design Concepts evaluate skylights it did not install?

Yes. Our free on-site evaluation covers the skylights already on your roof. We recommend repair, restoration and wet sealing, or replacement based on what we find.

How do I get a quote for VELUX Commercial skylights?
