Skylight Installation cost breakdown
At a mid-range, national-average baseline, a typical skylight installation project is estimated at $1,000 to $3,500. The table below breaks the cost down so you can see where your project is likely to land.
| Type | Typical installed cost | Notes |
|---|---|---|
| Tubular (sun tunnel) | $500 to $1,500 | Adds light cheaply |
| Fixed | $900 to $2,500 | Does not open |
| Vented (manual) | $1,000 to $3,500 | Opens for airflow |
| Solar / electric vented | $1,500 to $5,000 | Powered, may earn tax credit |
What drives skylight installation cost
- Skylight type: tubular, fixed, vented, or solar.
- Whether you use an existing opening or cut a new one.
- Roof type, pitch, and material.
- Interior shaft and drywall finishing.
- Flashing and waterproofing quality.
- Regional labor rates.
Key cost factors
Type and venting
Tubular sun tunnels are cheapest for adding light. Fixed skylights cost more, and vented (especially solar or electric) skylights that open are the priciest.
New opening
Cutting a new opening means framing, roof work, and finishing the interior light shaft, which adds significant labor over using an existing opening.
Waterproofing
Quality flashing and installation are critical, since a poorly installed skylight is a common source of roof leaks.
