A standard skylight typically costs between $1,000 and $2,000 to install, but prices climb fast depending on the size and style you choose and any special features you’d like, such as remote operation or solar-powered shades.
The biggest factor in your cost is the style of the skylight. Fixed skylights—which don’t open—are the most affordable. Ventilating skylights cost more but let in fresh air, making them ideal for bathrooms, kitchens, or stuffy upper-floor rooms. If you’re on a budget, tubular skylights offer a lower-cost way to bring in daylight without cutting a large hole in your roof.

Average Skylight Window Cost
Our research found that skylight window prices can start as low as $250 to swap out an existing basic-model window, but can exceed $3,000 for more intensive projects.
Skylight costs vary significantly because these windows have several different types and functionality levels. For example, if you select a small skylight or tubular model, 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 $3,000.
The installation difficulty also plays a key role in the cost. If you are adding a skylight to a roof that doesn’t have one, that costs much more than swapping out an existing window. The structure of the roof matters, too.
“If a roof is extremely steep or has tile shingles rather than asphalt, that could impact installation prices,” explained Mike O’Brien, head of Berthoud, Colorado-based Custom Exteriors roofing department.
| Cost Range | Cost Per Window |
| Low-end Cost Range | $250–$950 |
| National Average Cost Range | $1,000–$2,000 |
| High-end Cost Range | $2,100–$3,000 |

Pros & Cons Of Installing Skylight Windows
Skylight windows can transform a home by inviting natural light without sacrificing privacy or wall space. While they undeniably brighten any room and enhance its overall aesthetic, skylights have some drawbacks. Let’s dive into the pros and cons of installing a skylight window.
Pros
- Reduces the need for artificial lighting
- Maintains privacy while letting in natural light
- Enhances the appearance of a room
Cons
- Can increase cooling costs if not equipped with Low-E coating
- Costly installation for new opening
- Some skylights need to be opened manually with a pole or crank, though pricier models open with a remote control
What Factors Affect the Cost of a Skylight Window?
As with any window installation project, several factors can affect the final cost of your skylights. Understanding the implications of each will help you make the best decision for your home and budget.
Cost of Skylight Windows by Type
The type and shape of skylight windows have 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 more than $3000.
The following table shows standard price ranges for different skylight window models:
| Skylight Type | Low-End Cost | High-End Cost |
|---|---|---|
| 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 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 and $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 exist only 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 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” | $290 | N/A |
| 22” X 46” | $435-540 | $1,236 |
| 24” X 48” | N/A | $1,665-$1,960 |
| 30” X 30” | $500 | N/A |
| 36” X 36” | N/A | $1,110 |
| 30” X 46” | $615 | N/A |
| 32” X 32” | $830 | N/A |
| 32” X 48” | N/A | $1,834 |
| 48” X 48” | $1,030 | N/A |
| 22” X 27” | $475 | $615 |
| 44” X 46” | $675 | $1,150 |
| 28” X 52” | N/A | $950 |
| 36” X 52” | N/A | $1,023 |
| 52” X 52” | N/A | $1,065 |
| 10” diameter tube | $585 | N/A |
| 14” diameter tube | $680 | N/A |
| 21” diameter tube | $775 | N/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.
“People often buy wood windows because they like the look of the wood versus vinyl,” said Larry Shapiro, co-owner of Executive Remodeling in St. Louis Park, Minnesota. “However, wood windows tend to be more expensive than other materials, which causes buyers to choose something else.”
The following table shows potential cost fluctuations based on your roof window’s framing:
| Frame Material | Low-End Cost | High-End Cost |
|---|---|---|
| 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 skylights can be low-maintenance, durable, and energy-efficient for up to 30 years.
- Wood: This is the most premium frame option for skylights because of its costly manufacturing process and 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.
Skylight panes are typically crafted from either plastic or glass. “Skylights are only available in double panes due to safety issues,” O’Brien said.
Plastic glazing, usually made from acrylic or polycarbonate, is a more budget-friendly and sturdy option. However, the U.S. Department of Energy (DOE) notes that polycarbonate plastic glazing can yellow over time and allow more UV rays into your space. 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.
Although glass glazing is more expensive upfront, it’s more durable than plastic. Available in laminated or tempered options, laminated glass tends to be pricier but provides enhanced safety. Both types are designed to prevent the glass from shattering into large, sharp pieces, adding an extra layer of protection to your skylight window.
Low-e glazing is a feature commonly found in skylight windows. It enhances your home’s energy efficiency by helping regulate indoor temperatures, keeping your space comfortable year-round while reducing energy costs.
With that in mind, take a look at some average skylight window cost ranges based on glazing materials:
| Glazing Material | Low-End Cost | High-End Cost |
| Acrylic Plastic | $200 | $1,000 |
| Tempered Glass | $300 | $1,500 |
| Double-pane Glass | $500 | $2,000 |
Cost of Skylight Windows by Installation Method
The method of installing a skylight window—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 Method | Common 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.
General Skylight Installation and Labor Cost Information
O’Brien’s team charges $150 per hour for skylight installation. Depending on the window style and the scope of work, the job can take up to four hours, adding to the overall expense. O’Brien estimated that installing a skylight window in an existing opening in Colorado typically costs between $700 and $1,100 per window when it’s a direct replacement. This price range covers aluminum and wood framing materials, with wood usually falling on the higher end.
If you’re considering adding a new skylight to your home, expect higher costs since creating a new opening is required, and don’t overlook the potential fees for removing and disposing of an existing skylight. Expanding an already open area to fit a larger skylight can increase expenses, adding to the overall project cost.
How To Save Money on Skylight Installation
When it comes to saving on skylight installation, a little strategy goes a long way. Opting for simpler, more budget-friendly designs and carefully planning your installation location—such as choosing spots with easy roof access—can help you cut down on costs. So can getting multiple quotes and choosing more affordable materials. Energy-efficient skylights with solar capabilities lower energy bills and can make you qualify for clean energy tax incentives or rebates, putting more money back in your pocket.
Choose Affordable Materials
A smaller skylight window can significantly reduce installation costs without compromising on natural light. The size of the window isn’t the only factor, though—material choice matters, too. Aluminum and vinyl are cheap options that offer a good balance of durability and price. Wood sits at the top of the price range.
When it comes to shopping for windows, “vinyl is the least expensive option,” according to Chris Pound, owner and president of Window Source DFW in Carrollton, Texas. Vinyl’s affordability, combined with its durability and low maintenance, makes it a popular choice for homeowners looking to save without sacrificing quality.
Shop Around
Shopping around and obtaining at least three quotes from reputable window brands can help you assess factors such as installation, materials, and labor costs, ensuring you get the best deal. Make sure each quote request specifies the same window type, location, and project scope to receive an accurate comparison of the total cost.
Look for Discounts and Rebates
Installing solar skylight windows could qualify you for certain tax credits such as the Energy Star windows and skylights tax credit. If you install clean energy property between January 1, 2023, and December 31, 2032, you can claim 30% of the product cost, up to $600 per installation. The total annual limit for this efficiency tax credit is $3,200, with specific caps of $1,200 for windows, doors, and skylights.
To be eligible, your windows must meet the Energy Star Most Efficient criteria, which you can verify using the Energy Star Climate Zone Finder. To claim this tax credit, which directly reduces your tax liability dollar for dollar, file Form 5695 with your annual income tax return.
In addition to federal tax credits, you may be eligible for state tax incentives for installing solar skylight windows, and you might even receive rebates from your utility provider. For example, Puget Sound Energy in Washington offers up to $200 per window, depending on the efficiency boost. However, there are expiration dates and total limits for these rebates. Be aware that in some cases, these rebates could impact your federal solar tax credits. Consult a tax professional to ensure you maximize your benefits and correctly claim the tax incentives.
Additional Costs of Skylight Windows
The figures above account for the materials, installation, 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.
- 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.
Cost of Skylight Windows Vs. Other Window Types
The infographic below shows that skylights are among the most expensive windows you can add to your home. Their higher cost 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:
| Window Type | Low-End Cost | High-End Cost |
| Storm | $100 | $400 |
| Single-hung | $200 | $400 |
| Double-hung | $430 | $915 |
| Awning | $430 | $830 |
| Egress | $300 | $1,500 |

| Bow | $2,000 | $4,000 |
DIY Vs. Professional Installation for 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, but 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.
“Since skylights are adding a penetration into your roof assembly, installation details like sealing and flashing are critical to a well-performing and durable skylight,” explained Kyle Biega, an engineer with the DOE Buildings Technologies Office Residential Envelope Solutions portfolio.
Installing a skylight requires a thorough understanding of your roof type and the ability to accurately measure the pitch to choose the appropriate type and size of skylight. For example, a 22-inch acrylic dome skylight with a flexible tube and low profile flashing is designed for roofs with shingles and a pitch ranging from 14 degrees to 60 degrees. If your roof pitch is below 3:12, you should use a curb-mounted skylight, whereas if it’s above 3:12, a deck-mounted skylight is the way to go.
Ultimately, deciding to DIY or hire a professional should hinge on your skill level and comfort when cutting an opening in a roofing structure and measuring and selecting the correct skylight. If you’re unsure, a professional window installer might be worth the investment. A reliable installer will use high-quality materials and industry expertise, guaranteeing your new windows are durable and safe for your home.
