How Much Do Skylight Windows Cost?

Skylight windows typically cost between $1,000–$2,000, though prices can start as low as $250 and exceed $3,000. Skylight costs vary significantly because these windows have several different types and functionality levels. For example, if you select small skylights or tubular models, you’ll likely pay $250–$950 for materials and installation. Meanwhile, larger, more complex designs and operable roof windows can bring your skylight bill to over $2,000.

Cost RangeCost Per Window
Low-end Cost Range$250–$950
National Average Cost Range$1,000–$2,000
High-end Cost Range$2,100–$3,000

What Factors Affect the Cost of a Skylight Window?

With any window installation project, several factors will significantly affect the final cost of your skylights. Understanding the implications of each will help you make the best decision for your home and budget.

The following factors will affect how much you pay for a new skylight:

  • Type
  • Installation method
  • Window size
  • Window material

Below, I’ll detail how each of these factors affects the final cost of your skylight.

Cost of Skylight Windows by Type

The type of skylight window you choose has the most considerable impact on cost. Some roof windows are fixed into the roof and don’t open, making for easier installation and fewer mechanisms. Other more expensive skylights open and close to provide ventilation — these require more complex installation processes and materials, which leads to higher prices of up to $3,200.

 The following table shows standard price ranges for different skylight window models:

TypeCost Per Window
Fixed$435–$1,030
Dome$290–$1,110
Ventilating$615–$1,960
Remote Controlled$1,500–$3,200
Tubular$585–$775

Fixed Skylights

Fixed skylights are set into the roof without any operable parts. Like picture windows, they don’t open but exist to provide additional lighting and a clear view of the sky. The simple design of fixed skylights yields lower installation and material fees, which means costs typically range from $450–$1,050.

Dome Skylights

Instead of having flat windowpanes, dome skylights feature acrylic glazing that arches outward. These skylights provide visual appeal, enhanced light distribution, and superior water shedding. Depending on their size and glass material, dome windows generally cost between $300–$1,100.

Ventilating Skylights

Vented skylights open by hand or remote control to provide airflow into the home. They’re a good choice for rooms needing additional ventilation or moisture control. Vented skylights cost more than fixed models, often ranging from $600–$2,000. Larger skylights with high-end framing, specialty shapes, or remote-control operation can exceed $3,000.

Tubular Skylights

Tubular skylights, also known as solar tubes, are small pipe-like openings that distribute sunlight into the home. They don’t provide a view of the outside and solely exist to provide additional natural lighting. Solar tubes require less intrusive installation processes and fewer materials, yielding a lower average cost range of $585–$775.

Cost of Skylight Windows by Installation Method

The skylight window installation method — how the window is implemented into your home’s existing roof structure — impacts your final project costs. Below, I’ve detailed two common skylight installation methods: curb-mounted and deck-mounted.

Skylight Installation MethodCommon Price Range
Curb-mounted$500–$1,500
Deck-mounted$1,500–$2,500

Curb-mounted Skylights

Curb-mounted skylights are installed on a frame instead of directly into the roof structure. The installer fastens the window to the frame or “curb,” which is a box-like structure attached to the roof. Flashing is then applied around the curb’s perimeter to prevent water damage. Curb-mounted windows cost less than deck-mounted skylights — usually between $500 and $1,500 — because they require a less intrusive installation process.

Deck-mounted Skylights

Deck-mounted skylights are installed to sit flush with the roof. The window framing fastens directly into the sheathing for a sleeker, more uniform appearance. Since the installer must implement the window into the existing roof structure instead of on a pre-built frame, deck-mounted skylights cost more, typically $1,500–$2,500.

Cost of Skylight Windows by Size

Apart from the type of skylight window you select, size is usually the most consequential determinant of cost. Bigger skylights require more installation time and materials, which brings up the cost.

Below are the national averages from RSMeans to illustrate how the size of the skylight impacts its price.

Size (Inches)Cost Per Window (fixed)Cost Per Window (operable)
22” X 22”$290N/A
22” X 46”$435-540$1,236
24” X 48”N/A$1,665-$1,960

10” diameter tube$585N/A
14” diameter tube$680N/A
21” diameter tube$775N/A

Cost of Skylight Windows by Frame Material

The framing material affects the total cost of any window. Wood is generally the most expensive option, while vinyl is the cheapest. When choosing the frame for your skylight, consider your area’s climate and potential maintenance requirements. Some materials perform better than others regarding energy efficiency and durability.

The following table shows potential cost fluctuations based on your roof window’s framing:

Frame MaterialCost Per Window
Vinyl$200–$1,200
Aluminum$500–$1,500
Wood$600–$2,500
  • Vinyl: This is the lowest-cost frame material, typically ranging from $200–$1,200 for standard skylights. Vinyl frames provide excellent insulation, vast customizability, and low-maintenance appeal for up to 20 years.
  • Aluminum: Aluminum is a midrange-cost material for skylight windows. My research found that these often have a higher price point than vinyl (typically between $500–$1,500). However, aluminum offers low-maintenance, durable, and energy-efficient windows for up to 30 years.
  • Wood: This is the most premium frame option for skylights because of its costly manufacturing process and sought-after classic appeal. Wood skylights generally range from $600–$2,500. However, the higher price point may be worth it, as it brings superior energy efficiency and traditional style to your home.

Cost of Skylight Windows by Glazing Material

The cost of glazing impacts the cost of skylight windows, which is the glass-like portion of the window. When choosing between different glazes, consider your home’s insulation and durability needs.

Plexiglass skylights may be cheaper upfront but often become discolored and may yield higher energy costs over time. Meanwhile, homeowners in harsh climates with hail and wind might choose acrylic plastic over glass for its impact resistance and longer lifespan. In short, window materials aren’t one-size-fits-all. Take time to assess which option best suits your needs, roof type, and budget.

With that in mind, take a look at some average skylight window cost ranges based on glazing materials:

Glazing MaterialCost Per Window
Acrylic Plastic$200–$1,000
Tempered Glass$300–$1,500
Double-pane Glass$500–$2,000
  • Acrylic: Plexiglass skylights range from $200–$1,000. Plexiglass glazing is typically used for dome skylights and solar tubes because it can bow outward. It’s a cheaper glazing material, providing decent energy efficiency and shatter-proof impact resistance.
  • Tempered glass: This material undergoes an intense heating and cooling process, making it much stronger than traditional window glazing. For this reason, it costs more (usually between $300–$1,500) but provides superior strength in harsh weather climates.
  • Double-pane glass: Expect to pay a higher price point, even more than $2,000, because double-pane glass uses more materials. Despite their higher price point, these windows provide more cost-saving results. They feature two layers of glass separated by an argon gas filler for excellent energy efficiency and insulation.

Additional Costs of Skylight Windows

The figures above account for the materials and dimensions of skylights. However, you still need to account for several factors that can increase your skylight replacement cost. Installation fees, permits, customizations, and window brands can increase the cost of skylights by hundreds or even thousands of dollars.

  • Labor and installation: Labor costs make up a significant part of your total skylight installation costs. According to our research on RSMeans, a team of two sheet metal workers and two building laborers will add $237 per hour to your bill. The complexity of your skylight project also impacts this number.
  • Required permits: Some states require homeowners to acquire building permits to add skylights. These permits generally cost between $200–$500 but vary by project and municipality. 
  • Glass coatings: Adding tinting and coating to your skylights increases project costs. Low-E window film typically costs around $7.75 per square foot but can yield energy savings in the long run. Decorative and ceramic window tintings often cost between $5–$15 per square foot.
  • Brand: Different skylight brands have varying product price points. Shop around before committing to a specific brand to make sure you find your desired product and price.

How Does the Cost of Skylight Windows Compare to Other Window Types?

The infographic below shows that skylights are one of the most expensive windows you can add to your home. Their higher cost range is primarily due to the installation methods required for these rooftop windows.

However, with any window type, your price depends on the size, materials, and customizations you choose. This is why you may find a skylight window at the lower end of the cost range that aligns with standard casement or picture window prices. Likewise, you may design a custom skylight window with triple-pane glass and an operable frame that exceeds the costs listed below.

Regardless of your project, keep the following costs and use cases in mind when designing your home’s dream skylights:


Is DIY Worth the Cost Savings of Installing Skylight Windows?

If you’re considering DIY skylight installation as a money-saving method, make sure you have the skills needed for a successful home improvement project. You should only install skylights if you’re a knowledgeable do-it-yourselfer with window and roofing expertise.

Not only does the skylight installation process involve cutting an opening in your home’s roof, you’ll also be working in potentially dangerous areas. Plus, improper installation can damage the roof and lead to severe water damage or high energy bills.

I strongly recommend hiring a professional window installer to add new or replacement skylight windows to your home. A reliable installer will use high-quality materials and industry expertise, guaranteeing your new windows are durable and safe for your home.

Save money on labor fees
Complete the project at your own pace
Potential fall risks
Potential to damage your roof
Can cause leaks, drafts, and energy loss
Might lead to more maintenance costs and replacement needs down the road

The pros of hiring a professional installer far outweigh the benefits of going DIY. However, if you’re determined to install your own roof windows, make sure you fully understand the process before starting.

FAQs About Skylight Window Costs

Do Skylight Windows Come With Warranties?

Many skylight window brands offer 10-year warranties to cover defects in materials and installation. The specifics of each warranty vary by window type and product line, so you must assess any limitations and guidelines before purchasing.


Do Skylight Windows Add Resale Value to a Home?

Skylight windows are a modern design feature that can add resale value to your home. Though these windows generally cost between $1,000–$2,000 and sometimes exceed $3,000, they can vastly improve your home’s visual appeal, lighting, ventilation, and energy efficiency.

Note: When investing in skylights for potential resale value increases, be mindful of your climate. If you live in a wet climate, potential buyers might view the skylights as a leak risk.


Can Skylight Windows Go on Any Roof?

Modern window installation products and practices have made skylights possible for nearly any roof type. However, some roofing materials and structures can only support certain skylights.

Metal roofs require deck-mounted skylights, while shingles and tile roofs can support curb and deck-mounted skylights. Low-pitched and flat roofs require curb-mounted skylights to ensure the window has adequate support. If you have a truss roof, select a skylight that fits between the trusses to prevent them from being cut or notched during installation.


What are the disadvantages of having a skylight?

Skylights are expensive to install and maintain. Additionally, they are prone to leaking, which can lead to expensive repairs and water damage. The sunlight from skylights may also damage carpet and furniture from UV exposure.
