Skylight Prices

There are three popular skylight styles: fixed, ventilating, and tubular. Adjust your budget based on the model, your roof, the glass, and the brand you choose. Prices here are for the window only, with exceptions noted in the paragraphs below.

Skylight Prices by Type
Fixed$150 - $1,500
Ventilating$300 - $2,500
Tubular$450 - $1,300
Flat-Roof$250 - $2,000
Dome$250 - $3,000
Velux$1,100 - $3,700
Farkro$300 - $2,500
Pella$150 - $1,700
Sun-Tek$200 - $3,000
the average cost to install a skylight is $1,600 or $500 to $4,100.


Fixed skylights cost between $150 and $1,500. These are windows that do not open. They are installed for the purpose of providing additional light only. Fixed options are most popular for adding natural light through your roof.


Ventilating skylights range between $300 and $2,500. This opening style is best for kitchens or bathrooms, where they help remove excess moisture and keep a steady flow of air. Ventilation happens through a manual or motorized hand crank, a remote control, or a sensor-controlled thermostat.

Flat-Roof Skylight Prices

Expect to pay between $250 and $2,000 for windows designed for flat roofs. The general materials are the same, but leak-proofing must be more significant because water can pool on top of the opening. That includes sealing the edge of the glass to the frame, adding a dome cover to prevent water from pooling, and taking precautions to install the flashing at the perfect angle during installation.


Dome skylights range between $200 and $3,000. They are designed primarily for commercial applications and large windows. The dome-shaped design prevents water and condensation from forming. This option does not open and has no ventilation.

Velux Skylight Prices

A Velux skylight costs between $1,100 and $3,700 with installation included. The world's largest manufacturer offers anything from fixed to ventilating and even automated windows. An extensive 20-year leak warranty that also protects the glass makes up for the high price.

Velux also offers tubular skylights for $200 to $500, not installing installation.


Fakro skylights range between $300 and $2,500. In exchange, you get both fixed windows and vented units that can come with a manual, electric, or solar control for opening and closing. The warranty on these windows includes 25 years on the glass, and ten years against leaking.


Skylights from Pella vary between $150 and $1,700. This manufacturer does not focus on roof windows but offers them as part of a broader product line. They are inexpensive, but the more general 20-year warranty doesn't protect specifically against leaks.


Sun-Tek offers residential and commercial skylights for $200 to $3,000. You will find this brand at major home improvement stores, with products using acrylic or polycarbonate compounds instead of real glass. Its warranty only covers materials, with full cost reimbursement for the first ten years.

Price by Size

While custom sizes are possible, most roof windows come in these standard sizes:

Skylight Costs by Size
Size (w x h)Price
16" x 16"$150 - $600
16" x 24"$200 - $700
16" x 32"$300 - $1,000
24" x 32"$300 - $1,200
24" x 48"$500 - $2,000
24" x 72"$900 - $2,700
48" x 48"$1,100 - $3,500

If your roof opening does not fit these sizes, expect to pay at least 25% more for the unit than the next-closest standard option on this list.

Other Cost Factors

How you choose to finish the window might also affect your budget. Some units include pre-tinted or coated glass, and quotes from a pro will include the cost to install sealant or flashing around the window. The below prices are for individual materials only.

FactorsMaterial PricePurpose & Options
Glazing$20 - $50 Seals edges between glass and frame.
Single-glazed to triple-glazed
$100 - $250Improves durability and UV stability.

Average Cost to Install a Skylight

Depending on size and complexity, a pro will charge you between $500 and $4,000 for labor. Where your total falls on that range depends on the pitch, height of ceilings, and the room itself.

Skylight Sizes & Prices

Labor prices are directly related to the size of the window. You may only need to pay $500 for cutting a 16" x 16" hole in the roof, but a 48" x 48" hole will range up to $4,000.

The right size depends on more than just cost. If you choose the wrong size, it could be too small and fail its function of bringing in natural light. For example, a 16" x 16" opening might not be enough to light a large, open-space living area. If it's too large, air could escape, or water could leak in.

Details are essential for the installation. The opening in the roof and ceiling must be precisely aligned. If that doesn't happen, the window will not fit into the spot. Fixing that mistake will require more time and money.

Electrical Work

Vented skylights with remote controls may require electrical work that can range between $75 and $300. The cost to hire an electrician should be added to your overall budget because most installers will not lay wiring. They typically recommend a licensed pro experienced in this type of job.

Skylight Installation Cost Home Depot

Home Depot does not currently offer skylight installation in the U.S. The store sells windows from Velux and Fakro. Prices range from $140 for a 16" x 16" fixed skylight to $1,840 for a 48" x 48" alternative with mechanical ventilation.

Commercial vs. Residential Skylight Prices

Residential skylights cost between $500 and $3,000 to install, while commercial alternatives range between $1,000 and $4,000. Commercial roof windows tend to be bigger and use varied materials. Many businesses require safety glass and install these windows to save on lighting bills for large factories. Safety glass and dome shapes are common for business applications.

Solar Tube Lighting vs. Skylight Window

A tubular skylight costs between $450 and $1,300 for both product and installation. That's about 60% of the price for a roof window because the opening is smaller than fixed styles.

Tubular or "tunnel" options have been around since the 1980s. They are small, cylindrical-shaped windows typically installed in small rooms, hallways and closets.

These tubes can significantly decrease your energy costs by eliminating the need for electric lights during the daytime. They let in less light than a full roof window, which is enough to replace lighting for an entire room. Still, the natural light compares favorably with most ceiling lamps.

Tubular Skylight Cost

The tube itself costs between $150 and $600. Most tunnel lights are either 10" or 14" in diameter. A 10" tube provides the same amount of light as a 100W light bulb. A larger 14" alternative is even brighter and can light up to 300 square feet.

Solar Tube Installation Cost

Expect to pay $300 to $700 for installation. Most kits are designed for roof pitches between 15 degrees and 60 degrees. If your home doesn't fall into that range, you need custom installation and flashing. That drastically increases costs to as much as $1,200.

Labor is less expensive than for traditional roof windows. You don't have to cut new drywall, and the area to waterproof is significantly smaller. Professional costs will increase if you must go through an attic space to get to the sun.

Benefits of Installing Skylights

Experts agree that installing skylights increases your home's value, but the exact ROI is difficult to measure. Think of this upgrade like curb appeal; it stands out to potential buyers and helps them see the house in a better light.

Installing a roof window also provides benefits in energy efficiency and noise reduction.

Increased Energy Efficiency

Skylights can decrease your heating and electricity bills by up to 5% due to increased natural light. They bring in 30% more natural light compared to vertical windows. However, you also need to be careful which products and options you choose to maximize that potential benefit.

These windows are great for adding light to dark rooms and cutting back on electricity use from lamps.

The most efficient solution is double-pane glass and several coats of insulating glaze. A skylight shade will help reduce energy loss. Adding solar-powered blinds can increase your home's energy performance rating by up to 45%.

Installing the right product is key to realizing that efficiency. Cheap options can allow heat to escape or let in cold air.

Noise Reduction

If you're not careful, opening your ceiling can bring in more noises from the outside because you're removing buffer. Choosing the right product can help.

The least expensive skylights are single-pane and provide the least amount of insulation from outside noises. Moving to a double-pane alternative reduces noises up to 50%. Some triple-pane options promise noise reduction up to 95%.

Finally, windows that open via remote or thermostat are quieter than those with a motorized hand crank. Consider spending some extra money upfront if reducing noise is your priority.

Talk To Pros About Installing a Skylight

DIY vs. Hiring a Window Installer

Skylight installation requires precision. You must make sure that the exterior and interior openings line up correctly. Make a mistake in the measuring process, and you might have to cut a separate hole or buy a different window.

Mistakes are just as bad in the weatherproofing process. You can expect constant weather exposure. If you don't seal the edges, you might need to fix your leaking roof. The cost to repair water damage if you don't take care of the leak can range from $1,000 to $4,100.

For these reasons, professional installation is a worthwhile investment. Simpler alternatives, like tubular skylights, can be DIY projects if you possess the necessary expertise. For others, find a window installer near you to get a quote.


Do skylights add value to a home?

Although the exact dollar amount is unclear, skylights add some value to a home. Realtors tend to recommend them because they make an instant impression on potential buyers. The relatively low price makes this an often-recommended home improvement option when putting your house on the market.

What is a Low-E Coating, and what are the benefits?

Low-E coating minimizes the infrared and ultraviolet waves that come through the window without diminishing the overall light. Ultraviolet causes fabrics to fade over time, while infrared waves can cause skin damage and heat problems in your home. With low-E windows, you can prevent both.

What is skylight cladding?

Skylight cladding is an extra level of protection on the exterior of your roof window. It adds weather resistance and additional insulation. Consider it an outer 'skin,' often made of aluminum, to protect your roof around the opening.

What is a deck-mounted skylight?

Deck-mounted skylights sit directly on the roof deck. Compare that with curb-mounted options, which require you to build an extra layer between the frame and roof that acts as the connector. Products installed on the deck come with a built-in frame and curb, making them easier to install but requiring a standard-size window opening.

How long do skylights last?

The life expectancy of a skylight depends on the brand you choose, the quality of labor, and the climate. Areas with changing temperatures and lots of rain may see more frequent damage.

For most quality products and installations, you can expect a lifespan between 20 and 40 years. Some may fail sooner due to leakage, while others can last up to 55 years. Make sure both product and installation are covered by a warranty, should your window fail before then.
