Skylight Installation Cost: $1,000–$3,000 (Average $1,800) in 2026

Why does skylight installation cost so much?

The price mainly comes down to skylight type and how much roof work the installer has to do. A single skylight installation typically runs $1,000 to $3,000, averaging about $1,800 nationally (This Old House), which lines up closely with Angi’s reported average of $1,909 within a $1,011-$2,806 range. Fixr’s average runs a bit lower, at $1,523, reflecting a sample weighted toward smaller units. By type, fixed skylights average around $700 ($200-$1,200), tubular units average about $350 ($200-$500), and manual vented skylights average roughly $1,200 ($400-$2,000) (This Old House). Electric or solar-powered vented skylights cost far more — $4,350 to $7,250 installed in 2026 — because they add a motor, wiring, and often a rain sensor (Bill Ragan Roofing). Roof pitch matters too: tile or metal roofs require extra labor beyond a flat or shingle roof (Angi).

What affects the cost?

A few factors explain most of the gap between a $1,000 job and one costing $5,000 or more:

• Skylight type. Fixed units cost least, manual vented units cost more, and electric or solar-powered vented units cost the most because of the added motor and wiring (This Old House, Fixr, Bill Ragan Roofing).
• Frame and glazing material. Vinyl frames and acrylic/polycarbonate glazing are the budget picks; metal or wood frames and tempered or laminated glass push the price up (This Old House, Fixr).
• Size and shape. Larger openings and custom, non-rectangular shapes raise both material and labor cost (This Old House, HomeGuide).
• Roof pitch and material. Steep, tile, or metal roofs add labor time compared to a flat or asphalt-shingle roof (Angi, Bill Ragan Roofing).
• Installation method. Deck-mounted installs typically cost more than curb-mounted installs, since deck-mounted units require more roof-structure work (This Old House).
• Electrical work. Wiring an electric or solar-vented skylight adds roughly $435 to $793 on top of the base install (Fixr).
• Permits. Local permits typically add $50 to $500, depending on the jurisdiction (Angi, This Old House).
• Roof accessibility. Hard-to-reach or high-pitch roof areas increase labor time and cost (HomeGuide).

How to lower your skylight installation cost

• Choose a fixed or tubular skylight over a vented one if ventilation isn’t essential — the average cost gap between fixed ($700) and vented ($1,200) is significant, and it’s much larger versus electric-vented models (This Old House, Bill Ragan Roofing).
• Stick with vinyl frames and acrylic or polycarbonate glazing instead of wood frames or tempered/laminated glass, which cost more per unit (This Old House, Fixr).
• Ask about curb-mounted installation instead of deck-mounted where your roof allows it, since curb-mounted jobs tend to run cheaper (This Old House).
• Install multiple skylights in one visit if you’re adding more than one — doing several units together lowers the per-unit labor cost (Fixr).
• Skip powered features you don’t need. Electric or solar venting adds thousands to the install and another $435-$793 for wiring alone, so a manual vent unit can cover the same need for far less (Fixr, Bill Ragan Roofing).
• Get quotes from more than one installer. Contractor pricing varies widely — Bill Ragan Roofing’s full-service quotes run well above the Fixr and This Old House averages, so comparing bids can reveal real savings.

Prices vary by region, roof type, and skylight model, so treat the figures above as a planning budget. Confirm whether flashing, permits, and any electrical work are included before committing to a final quote.
