What Affects Skylight Installation Cost?
Skylight type, quantity, roof type, complexity, and location drive most of the variation.
- Skylight type — Fixed is usually cheapest; vented costs more; tubular is often lower per unit for small openings.
- Number of units — Multiple skylights often cost less per unit due to shared setup and access.
- Roof type — Asphalt is standard; metal and flat roofs can add 15–25% for flashing and labor.
- Complexity — Steep pitch, tight access, or framing changes increase labor and cost.
- Location — Labor rates vary by region; high-cost areas can be 20–30% more.
- Size (tubular) — Larger tube diameter (e.g. 21") costs more than small (10") for materials and install.
