Skylight installation cost depends on whether you are replacing an existing unit or creating a new opening through the roof and ceiling. As a regional example, Talya Roofing’s Savannah cost guide lists $1,500–$3,000 for an installed fixed skylight and $2,500–$5,000 for a solar/electric venting model.
These are the contractor’s published Savannah-area references, not nationwide averages. For your home, confirm the unit, roof work, flashing and interior finish separately. A roof installation quote may leave out work needed to finish the ceiling below.

Skylight Installation Cost at a Glance
| Published reference | Price | Scope to understand |
|---|---|---|
| Talya Roofing, Savannah: fixed skylight | $1,500–$3,000 installed | Regional reference including the unit, labor and manufacturer flashing. Confirm your ceiling and shaft requirements. |
| Talya Roofing, Savannah: solar/electric venting skylight | $2,500–$5,000 installed | Regional product-and-installation reference; verify the exact model and controls. |
| Homewyse, May 2026: frame a skylight opening | $505–$955 per opening | Modeled framing work only, under stated conditions; not a complete installed skylight. |
Homewyse’s skylight-opening calculator describes a particular wood-framed roof-opening project. Its estimate does not establish the price of the skylight, complete roofing integration or a finished interior shaft.
Do not automatically add that framing figure to an installed-price quote. First establish whether framing is already included. Applicable taxes, permit fees and work outside each source’s stated scope need separate confirmation.
Replacement vs. a New Roof Opening
Replacing an existing skylight
Start with the existing unit’s identification, dimensions and mounting arrangement. Ask the installer to inspect the surrounding roof and any curb before deciding what can be retained.
Have the quote explain whether it includes new flashing, removal of the old unit, roof repairs and interior touch-ups. “Same size” does not establish that every existing component is suitable for reuse.
Adding a skylight to a new location
A new location requires an assessment of both the roof and the space below it. Ask the contractor to verify the proposed opening, framing, roof covering and ceiling arrangement before ordering.
If structural changes are proposed, confirm who designs or approves them. Do not treat a standard unit size as proof that it can fit anywhere in the roof.
Building a light shaft through an attic
When the room ceiling sits below the roof, ask how daylight will reach the room. The proposal should describe any required shaft and its interior finish.
Confirm responsibility for framing, insulation, air sealing, drywall, trim and painting. Request a completed-room price alongside the roof-work price.
Choose the Skylight Type Before Comparing Quotes
Fixed skylights
A fixed skylight provides daylight without opening for ventilation. Ask for the exact size, glazing and mounting configuration.
Compare equivalent products rather than treating every fixed unit as interchangeable.
Venting skylights
For an opening model, specify how it will operate: manually, electrically or with a solar-powered operator.
Ask what controls, screens and accessories are included. Have the installer verify any wiring or accessory requirements for the selected model rather than assuming every powered system needs the same work.
Tubular daylighting
A tubular daylighting system may be worth comparing when the aim is to brighten a smaller interior space.
Ask for a separate proposal covering the roof component, tube route and ceiling diffuser. It is a different product from a conventional skylight, so compare the result you want as well as the price.
What Can Increase Skylight Installation Cost?
Roof material, pitch and access
Provide the installer with the roof type and known access restrictions. Ask how those conditions affect the chosen product and installation method.
Confirm whether roof-covering removal and replacement, access equipment and protection of the property are included.
Mounting and flashing compatibility
Ask the contractor to identify the mounting system and flashing specified for the unit and roof.
VELUX’s professional skylight resources distinguish deck-mounted and curb-mounted products and provide model-specific installation information.
The quote should identify compatible components and the manufacturer instructions the installer will follow. Avoid accepting “seal around skylight” as the entire description of weatherproofing work.
Existing damage
Agree on how the contractor will handle deterioration found after opening the roof.
Ask for an explanation, documentation and an additional price before authorizing repairs outside the original scope. If broader roofing work is needed, our roof repair cost guide covers that separate budget.
Interior finishing and accessories
Check whether the total includes a finished shaft, trim, paint and any selected shade.
For high ceilings, ask how the unit and accessories will be operated and serviced. Include the chosen controls in the product specification.
Permits and approvals
Confirm requirements with the local building department before work starts. Ask who obtains the permit, schedules inspections and supplies completion records.
Also check any applicable association or historic-property approvals before committing to a location or ordering a custom unit.
Repair or Replace a Leaking Skylight?
Ask for a diagnosis before choosing the remedy. Request an assessment of the unit, flashing, surrounding roofing and interior moisture.
Compare a clearly described repair with a replacement proposal. Have the contractor explain what each option addresses and which conditions remain outside its scope.
A stain beneath a skylight does not, by itself, establish which component has failed. Avoid approving a replacement solely because the quote describes every moisture problem as a defective skylight.
How to Compare Two Skylight Quotes
These numbers are fictional examples, not market estimates. Both use the same fixed unit and assume the same existing opening, with no hidden damage or new shaft.
| Item | Quote A | Quote B |
|---|---|---|
| Same skylight unit | $650 | $650 |
| Roof installation labor | $900 | $1,300 |
| Specified flashing and related materials | $220 | Included |
| Old-unit removal and haul-away | $100 | Included |
| Interior touch-up work | $160 | Included |
| Illustrative subtotal | $2,030 | $1,950 |
Quote B is $80 lower for the stated scope. Both examples exclude taxes, permits, structural changes and hidden repairs.
Confirm that the included materials and finish work match. Use our contractor hiring checklist to compare credentials, written exclusions and warranty terms.
Energy Performance and Warranty Checks
ENERGY STAR’s buying guidance recommends selecting certified products for your climate zone and following manufacturer installation instructions.
Ask for performance information for the exact size and glazing configuration. Consider daylight, glare and heat control together rather than choosing the largest opening automatically.
Request the product warranty and installer’s workmanship warranty in writing. Ask which components, installation conditions and documentation are required for any advertised coverage.
What to Confirm Before Final Payment
Review both the roof work and the finished room. Ask the installer to demonstrate any opening mechanism, shade or control and explain the care requirements.
Confirm the agreed inspection or testing is complete and record any remaining finish work. Keep the invoice, model identification, applicable permit records and warranty documents together.
Frequently Asked Questions
Does skylight installation include the interior ceiling work?
Not always. Ask specifically about the light shaft, insulation, drywall, trim and painting.
Is replacing a skylight cheaper than adding a new one?
Compare actual scopes. Reusing a suitable opening may reduce work, but roof damage, incompatible components or interior repairs can change the total.
Can a skylight be installed on any roof?
Have the installer assess the roof construction, covering, pitch and proposed product. Do not assume one model or flashing system suits every roof.
Should I replace skylights when replacing the roof?
Ask for both options to be priced during the roof assessment. Compare retaining the existing units with replacing them, including flashing work and warranty implications.
Does a solar-powered skylight need electrical wiring?
Have the installer verify the requirements of the exact unit and accessories. Do not apply the wiring requirements of an electric model to every solar-operated product.
Can I install a skylight myself?
This guide budgets for professional assessment and installation. Roof access, structural work and weatherproofing should be handled by appropriately qualified contractors.
Before You Approve the Installation
Confirm whether the job replaces an existing unit or creates a new opening. Specify the skylight, flashing, roof repairs and completed interior finish before comparing totals.
That gives you a clearer budget for the complete project, rather than only the work visible on the roof.
