A VELUX skylight typically costs $500-$3,000 for the unit, while a professionally installed project commonly totals $1,500-$5,000. The final price depends on skylight type and size, roof access, interior finishing, and whether the job is a new installation or a replacement.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Fixed skylight unit | $500 | $850 | $1,400 | Price varies by size and glazing |
| Venting skylight unit | $900 | $1,600 | $3,000 | Manual or powered opening |
| Standard installation | $1,000 | $2,000 | $3,500 | Labor and basic flashing |
| Installed project | $1,500 | $3,000 | $6,500 | Higher totals for complex roofs or finishes |
What VELUX Skylights Cost by Type and Size
Fixed VELUX models are generally the least expensive, at about $500-$1,400 for the unit. Standard venting models often cost $900-$2,200, while solar-powered or electric venting units can run $1,500-$3,000 before installation. Larger units, upgraded glazing, blinds, and controls increase the price.
For a typical 2-by-4-foot unit and straightforward roof access, a fixed skylight installation may total $1,500-$3,000. A powered venting model with ordinary interior finishing may reach $2,500-$5,000. Budget by installed system, not just the sticker price of the skylight.
Assumptions: U.S. contractor pricing, standard asphalt-shingle roof, normal access, and no major structural changes.
Where the Skylight Installation Quote Goes
Contractor estimates combine the unit with roof work, weatherproofing, and any interior repairs. The ranges below are typical allowances for one skylight; difficult access or premium finishes can push costs above them.
| Cost item | Low | Average | High | Typical scope |
|---|---|---|---|---|
| VELUX unit | $500 | $1,200 | $3,000 | Fixed through powered venting |
| Labor | $700 | $1,300 | $2,500 | Roof opening, setting, sealing |
| Flashing and roofing materials | $150 | $350 | $700 | Compatible flashing and shingle repair |
| Interior finishing | $150 | $500 | $1,200 | Drywall, trim, paint, or light well |
| Removal and disposal | $100 | $250 | $500 | Old skylight and roofing debris |
Labor and interior finishing can add as much as the unit itself on a new opening. is a useful way to compare labor estimates; many roofing or skylight crews charge roughly $75-$150 per hour per worker, though fixed project bids are common.
How Roof Pitch, Opening Size, and Controls Change the Price
A replacement using an existing opening is usually less costly than cutting a new opening. Creating a new opening can add $500-$1,500 for framing, ceiling work, and additional weatherproofing. A unit wider than 2 feet or longer than 4 feet may require more labor and a larger shaft or light well.
Roof pitch and material also matter. A steep roof above roughly 8:12, a tile or metal roof, or a two-story setup may add $300-$1,200 for access, specialized flashing, or slower installation. Solar and electric controls can add about $500-$1,500 compared with a basic fixed model. Confirm that the quote includes flashing compatible with the roof type and the selected VELUX model.
Three VELUX Project Examples With Installed Totals
A like-for-like replacement of a small fixed unit might include a $700 skylight, 5 labor hours at $100 per hour, and $250 for flashing and disposal, totaling about $1,450 before any interior repair.
A new 2-by-4-foot manual venting unit could cost $1,300, with 10 labor hours at $110 per hour and $600 for materials and basic drywall finishing. The estimated total is $3,000.
A solar-powered unit on a steep roof might include a $2,300 skylight, 14 labor hours at $125 per hour, and $900 for access, flashing, and interior work, for a total near $4,950. These examples assume one unit and no structural damage or major code upgrades.
How Long Roof Crews Need for a VELUX Installation
A straightforward replacement can take 4-8 labor hours, often completed in one visit. A new skylight opening commonly requires 8-16 labor hours, with additional time for drywall compound and paint to dry. Two workers may be on site for part or all of the job, so crew hours and elapsed time are not the same.
Ask whether the bid includes interior finishing, cleanup, and protection from rain during installation. A quote that excludes drywall or painting may appear cheaper but leave a separate $200-$1,000 expense.
Removal, Flashing, and Permits That Can Add Fees
Removing an old skylight usually adds $100-$500, depending on disposal and roof repairs. New flashing or shingle replacement may add $150-$700. If water damage or rotted framing is found, repairs can add $300-$1,500 or more after the roof is opened.
Permit rules vary by city and by whether the work changes the roof structure. A basic replacement may not need a permit, while a new opening can trigger a fee of roughly $50-$500 and an inspection. Verify local permit requirements before comparing final bids.
Regional VELUX Installation Prices Across the U.S.
Labor markets affect installed totals even when the skylight model is the same. Large metro areas and high-cost coastal markets may run 10%-25% above the national midpoint; rural areas may be 5%-15% lower, although travel or contractor minimums can narrow the difference.
Storm-prone regions may require more weatherproofing, while cold climates often favor higher-performance glazing. Those choices can add $100-$600 per unit. Compare local bids for the same model, glazing, flashing, and finishing scope rather than comparing headline totals alone.
Ways to Lower a VELUX Skylight Project Price
Replacing a unit in an existing opening usually costs less than changing its size or location. Keeping the same operating type, avoiding optional blinds or upgraded controls, and choosing standard glazing where appropriate can limit the equipment budget. Combining two nearby skylights into one scheduled visit may reduce duplicated setup charges.
Get at least three itemized quotes and ask contractors to separate unit, labor, flashing, disposal, and interior work. Schedule the work when crews are available rather than requesting emergency service after a leak. Do not cut costs by omitting proper flashing or weatherproofing; a leak repair can exceed the initial savings.
