Skylights flood interior spaces with natural light, reduce daytime electricity use, and add architectural interest to any room. The national average cost to install a single skylight is around $2,800, including the unit, flashing kit, and labor. Fixed skylights are the most affordable and common choice, while venting (operable) skylights cost more but provide valuable airflow for kitchens, bathrooms, and loft spaces. Proper installation and flashing are critical — a poorly installed skylight is one of the most common sources of roof leaks.
Fixed skylights are sealed units that do not open — they provide light only. They are simpler to install, less expensive, and have fewer potential leak points. Venting skylights open to allow airflow, which is especially beneficial in bathrooms, kitchens, and upper floors where heat accumulates. Manual venting skylights use a hand crank or pole, while electric and solar-powered models open and close with a remote control or smart home integration. Solar-powered venting skylights from VELUX qualify for a 30% federal tax credit through 2032.
Skylights range from compact 14×14-inch units for small bathrooms to large 30×46-inch or wider units that serve as a focal point in living areas. Glazing options affect energy efficiency, UV protection, and light control. Double-pane low-E glass is the standard and provides good insulation. Triple-pane glass offers superior energy efficiency for cold climates. Laminated inner glass is required by code in some areas and recommended everywhere for safety — it holds together if cracked, preventing glass from falling into the room.
There are two primary skylight mounting methods. Curb-mount skylights sit on a raised wooden frame (curb) built on the roof deck — they are easier to install and replace but sit higher above the roofline, which some homeowners find less aesthetically pleasing. Deck-mount skylights attach directly to the roof deck and sit nearly flush with the roofing surface for a cleaner profile. Deck-mount units require a manufacturer-specific flashing kit that integrates with the surrounding shingles. Deck-mount is the standard for new construction and most retrofits on pitched roofs.
Tubular skylights (also called sun tubes or light tunnels) are a cost-effective alternative for bringing natural light into interior rooms, hallways, and closets where a traditional skylight is impractical. A reflective tube channels sunlight from a small rooftop dome through the attic and into the room via a ceiling-mounted diffuser. Sun tubes are less invasive to install than traditional skylights, require no structural roof framing modifications, and work well in spaces where a direct line of sight to the sky is not available.

Skylight installation is skilled work that involves cutting through the roof deck, framing the opening, installing the unit and flashing, and finishing the interior drywall and trim. A single skylight installation typically takes one full day for a two-person crew. If the ceiling is vaulted and open to the roof, the interior finish is straightforward. If there is attic space between the roof and the ceiling, a light shaft (also called a light well) must be built from the roof opening down to the ceiling, adding $500–$1,500 in framing and drywall costs.
A single skylight installation takes 1 day. Multiple skylights or light shaft construction may take 2–3 days.
A properly installed skylight with a manufacturer-specific flashing kit should not leak. Most skylight leaks result from improper flashing installation, not the skylight unit itself. Choosing a qualified installer who follows the manufacturer's installation guidelines is the single most important factor in preventing leaks.
Modern skylights with double-pane low-E glass and argon gas fill are highly energy efficient. They reduce the need for artificial lighting during the day and, when vented, provide natural cooling ventilation. ENERGY STAR-rated skylights can qualify for a 30% federal tax credit. However, south-facing skylights in hot climates may increase cooling costs without proper glazing or blinds.
Quality skylights from brands like VELUX and Fakro last 20–30 years. The most common maintenance issue is seal deterioration, which can cause condensation between glass panes after 15–20 years. Flashing should be inspected during any roof replacement and replaced if showing wear.
Skylights can be installed on most pitched roofs (minimum 3/12 slope for deck-mount). Flat roofs require curb-mount units with proper drainage considerations. The main structural requirement is that the opening does not cut through more than one rafter — if it does, a structural header must be installed, adding $300–$800 to the project.
