The Roofing Brief Industry Reports. The US skylight and daylighting market sits at the intersection of residential remodeling demand, commercial energy codes, and a decades-long push to cut lighting electricity with natural light. This report aggregates verified figures from federal agencies, energy-code bodies, market-research firms, and construction-cost datasets into one citable reference. Market-size estimates from private research firms vary by methodology and are labeled as such. Federal energy data is treated as the primary anchor.

Market size and growth
Private market-research firms publish diverging figures for the skylight market because they define the category differently. Some count only architectural skylights, others fold in roof windows, tubular daylighting devices, and smoke vents. The estimates below should be read as directional, not precise, and the base years differ by firm.
| Segment | Base value | Forecast value | CAGR | Source (Tier) |
|---|---|---|---|---|
| US skylights (estimate A) | 1.8B (2024) | 3.0B (2033) | ~6.2% | Verified Market Research (T2) |
| US skylights (estimate B) | 2.1B (2024) | 3.2B (2033) | 4.8% | Vantage Market Research (T2) |
| Global skylights | 4.8B (2025) | 7.6B (2035) | 4.7% | Vantage Market Research (T2) |
| Global building daylighting systems | 4.2B (2024) | 8.9B (2033) | 8.4% | MarketIntelo (T2) |
| Global tubular skylights | 0.57B (2024) | 1.04B (2033) | 6.9% | SkyQuest (T2) |
All values in US dollars. Where two firms cover the same segment, both are shown rather than averaged, because averaging estimates built on different definitions would create a false-precision number. The broader daylighting-system market grows faster than the skylight-only market in every forecast reviewed, which reflects the addition of controls, sensors, and tubular devices to the base product.
Manufacturers and consolidation
The US skylight supply base includes VELUX, FAKRO, Solatube International, Wasco Products, Sun-Tek, Bristolite, CrystaLite, Natural Light, and Kingspan Light + Air, among others. Brand-share figures for this category are not published by any federal source, so the VELUX and FAKRO share numbers cited here are industry estimates and are flagged Tier 3.
The clearest verified structural signal is consolidation. Kingspan Light + Air USA acquired Solatube International, a global manufacturer of tubular daylighting devices, in a transaction that closed December 10, 2021. Terms were not disclosed. Source: Metal Construction News, 2021 (Tier 3 trade press).
Energy demand: why daylighting exists
Skylights and tubular daylighting devices compete against electric lighting, so lighting-energy data defines the addressable problem. US residential lighting used about 81 billion kWh in 2020, roughly 6 percent of home electricity. US commercial-building lighting used about 208 billion kWh in 2018, roughly 17 percent of commercial electricity. US manufacturing facility lighting used about 53 billion kWh in 2018, roughly 6 percent of manufacturing electricity. Source: US Energy Information Administration.
Commercial buildings are the larger daylighting opportunity per square foot because lighting is a bigger share of their electricity load. That is also where energy codes concentrate skylight mandates. The 28 percent average savings figure for daylighting controls comes from a 2012 ACEEE proceedings paper and is dated; it is included as context, not as a current guarantee.
Product energy performance and codes
ENERGY STAR certified windows and skylights lower household energy bills by an average of up to 13 percent nationwide versus single-pane windows, under Version 7.0 effective October 23, 2023. A standard double-pane window admits about 75 percent of the sun’s heat, which is why skylight U-factor and solar heat gain coefficient (SHGC) requirements vary by climate zone. Source: ENERGY STAR.
On the commercial side, ASHRAE 90.1 and the IECC require skylights in large enclosed spaces. In an enclosed space greater than 2,500 square feet, directly under a roof with at least 75 percent of the ceiling area higher than 15 feet, the daylight zone under skylights must be at least half the floor area. Skylights must provide either a skylight area of at least 3 percent of the daylight zone where visible transmittance is at least 0.40, or a skylight effective aperture of at least 1 percent. Where general lighting in the daylight zone draws 75 watts or more, photocontrols are required. Source: ANSI/ASHRAE/IES Standard 90.1 and IECC.
Costs and pricing
Installed skylight prices depend on type, size, roof pitch, and labor market. The 2026 cost datasets reviewed show the following US ranges.
| Type | Installed cost (US, 2026) | Unit only |
|---|---|---|
| Tubular / sun tunnel | 500 to 1,000 dollars | 150 to 500 dollars |
| Fixed skylight | 1,500 to 4,000 dollars | 150 to 800 dollars |
| Vented skylight | 1,600 to 4,700 dollars | 300 to 2,000 dollars |
| National average (all types) | ~1,800 dollars (1,000 to 3,000) | varies |
Source: Angi and HomeGuide construction-cost data, 2026 (Tier 2). Labor typically runs 500 to 1,500 dollars depending on complexity. Tubular devices are consistently the lowest-cost daylighting option because they require a smaller roof opening and no structural framing changes.
Original synthesis (Roofing Brief calculations)
The following figures are derived by The Roofing Brief from the cited public estimates. They are calculations, not published statistics, and inherit every limitation of their inputs, including mixed base years and differing firm methodologies.
- The US is roughly 40 percent of the global skylight market. Roofing Brief calculation. Inputs: US skylights 1.8 to 2.1 billion dollars (2024) divided by global skylights 4.8 billion dollars (2025). Result: about 38 to 44 percent. Limitation: base years differ by one year and the numerator and denominator come from different firms with different category definitions.
- Tubular devices are roughly 12 percent of the global skylight market. Roofing Brief calculation. Inputs: global tubular skylights 570 million dollars (2024, SkyQuest) divided by global skylights 4.8 billion dollars (2025, Vantage). Result: about 11.9 percent. Limitation: some market models count tubular devices inside the skylight total and some count them separately, so this ratio may double-count or under-count depending on the underlying definitions.
- A tubular daylighting device costs roughly 70 percent less to install than a fixed skylight. Roofing Brief calculation. Inputs: tubular installed midpoint 750 dollars versus fixed installed midpoint 2,750 dollars (Angi and HomeGuide, 2026). Result: about 73 percent lower. Limitation: midpoints of published ranges, not transaction data.
- The building daylighting-system market is on track to double in about 8.6 years. Roofing Brief calculation. Input: 8.4 percent CAGR (MarketIntelo, 2024), applying the rule of 72 (72 divided by 8.4). Result: about 8.6 years to double. Limitation: the rule of 72 is an approximation and assumes the forecast CAGR holds.

Methodology
Sources were selected by tier. Federal agencies (EIA, ENERGY STAR) and consensus energy-code bodies (ASHRAE, IECC) were treated as primary and given priority for energy and code claims. Private market-research firms were used for market-size and cost claims because no federal source publishes skylight market value, and each such figure is labeled with its firm and tier. Where two firms covered the same segment, both figures were shown rather than blended. Conflicting numbers were retained and flagged rather than reconciled into a single number. Derived figures are labeled as Roofing Brief calculations with their inputs and limitations. Any figure that could not be traced to a source fetched during research was excluded. Brand-share and dated academic figures are labeled Tier 3. Last updated August 2026.
