How to use the skylight installation cost calculator
- Say whether this is a new opening or a replacement in an existing curb or shaft.
- For a new opening, pick the type — fixed (non-vented), manual vented, electric or solar vented, or a tubular skylight.
- Enter the number of units. The total is the per-unit typical times the count.
Roof area and shingle counts stay on the roofing calculator. A full roof replacement is priced on the roof replacement cost calculator. Windows in walls are on the window replacement page.

HomeGuide’s article is dated Aug 29, 2025; Fixr was updated Jan 31, 2025. Tile, metal and low-slope roofs, a long attic chase, drywall and paint, or an electrician for a vented unit will push a bid above these national figures.
A worked example: one new fixed skylight
The three type-specific central values for a new fixed unit are $2,750 (HomeGuide), $1,800 (Angi) and $2,425 (RoofingCalculatorHQ’s medium 22 × 46). The median is $2,425, with a spread of $1,800–$2,750. Two replacement units at the $1,600 typical are $3,200.
Sources & assumptions
How this calculator gets its numbers. Full method: our methodology.
- New-opening typicals for fixed, vented and tubular are the median of three type-specific guides. New electric or solar uses two new-installation guides only (HomeGuide and RoofingCalculatorHQ; typical $3,800); The Roofing Brief electric range is replacement-oriented and is not averaged in. Replacement uses three overall replacement ranges, because not every guide splits a used opening by type.
- HomeGuide dated Aug 29, 2025; Fixr updated Jan 31, 2025; RoofingCalculatorHQ figures are a Q1 2026 asphalt-roof baseline.
- Tile, metal, slate and low-slope roofs, attic chases and electrical work can raise a bid above these national figures.

Frequently asked questions
How much does it cost to install a new fixed skylight?
The median of three type-specific guides is $2,425 installed, with those central values running from $1,800 to $2,750. A tubular unit is typically $935, and an electric or solar unit $3,800, from two new-installation guides.
Is a replacement skylight cheaper than cutting a new opening?
Usually. The three overall replacement ranges have a median of $1,600, below the new-fixed typical of $2,425. Reusing the opening avoids most of the framing, flashing and interior finish work.
Does this include a tile or metal roof?
The type-specific tables are asphalt-roof baselines where the source says so. Tile, slate, metal and low-slope membranes cost more, sometimes a lot more, and need a local quote.
Why is Fixr used for replacements but not for every new type?
Fixr publishes a project average and a range, not a full type-by-type 2026 table. It is one of the three replacement sources, and its January 2025 date is shown in the comparison.
