The Real Cost to Put in Skylight: Everything You Need to Know
Many homeowners dream of adding more natural light into their homes, and one of the best ways to achieve this is by installing a skylight. But before moving forward, it’s natural to wonder about the cost to put in skylight and what factors can influence the price. Skylight installation isn’t just about cutting a hole in the roof—it involves choosing the right style, selecting proper materials, ensuring energy efficiency, and hiring skilled labor. All of these elements come together to determine the total expense of the project.
This guide takes a deep dive into the cost of skylights, exploring the types, installation requirements, maintenance, and benefits. By the end, you’ll have a clear idea of what to expect when budgeting for this kind of upgrade.
Why Install a Skylight?
Before we look at the dollars and cents, it’s helpful to understand why homeowners often choose skylights:
- Natural Light: A skylight brings in daylight that brightens rooms where windows are limited.
- Energy Savings: With more sunlight, you can reduce reliance on electric lighting during the day.
- Ventilation: Venting skylights can be opened to allow airflow, improving indoor air quality.
- Aesthetics: Skylights add architectural interest, making rooms feel larger and more welcoming.
- Resale Value: Buyers often view skylights as a premium feature that adds appeal to a property.
Of course, these benefits come with an investment, so let’s examine what goes into the cost.
Average Cost to Put in a Skylight
On average, the cost to put in a skylight ranges from $1,000 to $4,000 per skylight, depending on type, size, and complexity of installation. Some small, basic fixed skylights may cost as little as $500 installed, while large or custom motorized skylights can exceed $10,000.
Here’s a breakdown of what usually drives costs:
- Skylight unit price: $150 – $2,000+
- Installation labor: $500 – $3,000
- Roof type and slope: Complex or steep roofs add cost
- Interior finishing: Drywall, painting, or trim work can add another $300 – $1,500
Types of Skylights and Their Costs
The type of skylight you choose plays a major role in the overall cost.
1. Fixed Skylights
- Description: Non-opening, designed only for light.
- Cost: $150 – $1,000 (unit); $500 – $2,000 (installed).
- Best For: Areas where ventilation isn’t needed, like hallways or stairwells.
2. Venting Skylights
- Description: Can be opened manually or electronically for airflow.
- Cost: $300 – $2,500 (unit); $1,000 – $4,000 (installed).
- Best For: Bathrooms, kitchens, or attics where moisture and heat need control.
3. Tubular Skylights (Solar Tubes)
- Description: Small, round skylights that channel sunlight through a reflective tube.
- Cost: $200 – $700 (unit); $600 – $1,500 (installed).
- Best For: Small spaces like closets, pantries, or hallways.
4. Custom Skylights
- Description: Large, uniquely shaped, or designed for specific architectural needs.
- Cost: $2,500 – $10,000+ (installed).
- Best For: High-end homes, atriums, or large open spaces.
Factors That Affect the Cost
When asking about the cost to put in skylight, it’s important to look beyond just the unit price. Several factors can raise or lower the total investment.
1. Roof Type and Material
- Asphalt shingles are the easiest and cheapest to cut into.
- Tile, slate, and metal roofs require specialized labor, increasing cost.
2. Roof Pitch and Accessibility
- A steep roof or one that’s hard to reach increases labor difficulty.
- Flat roofs may need additional waterproofing layers.
3. Skylight Size
- Larger skylights allow more light but are more expensive and require additional structural support.
4. Glazing and Glass Type
- Single-pane skylights are cheaper but less efficient.
- Double or triple glazing, low-E coatings, and tempered or laminated glass increase costs but improve insulation and safety.
5. Manual vs. Motorized Operation
- Manual venting skylights are budget-friendly.
- Motorized models with rain sensors and remote control can add $1,000 or more.
6. Interior Finishing
Cutting into the roof is only part of the job. Inside the house, drywall, paint, and trim may be required to complete the look.
DIY vs. Professional Installation
DIY Skylight Installation
Some homeowners consider a do-it-yourself approach. A tubular skylight, for example, is relatively straightforward for an experienced DIYer. Costs can be as low as $500.
However, improper installation can lead to:
- Roof leaks
- Poor insulation
- Warranty voids
- Safety risks from cutting roof rafters incorrectly
Professional Skylight Installation
Hiring a professional roofer or skylight contractor is more expensive, but it ensures the job is done correctly. Labor alone can range from $500 to $3,000 depending on complexity. In the long run, professional installation often saves money by preventing costly water damage.
Additional Costs to Consider
- Flashing Kits: $100 – $400 (essential for waterproofing).
- Shades/Blinds: $200 – $800 (to control light and heat).
- Electrical Wiring: For motorized skylights, expect $500 – $2,000 extra.
- Permits: Some municipalities require permits for structural changes ($50 – $300).
- Roof Reinforcement: Cutting into trusses may require engineering review and reinforcement.
Energy Efficiency and Skylights
A skylight can help reduce lighting costs, but it can also increase heating and cooling bills if not properly designed. Energy-efficient skylights feature:
- Low-E glass: Reduces heat transfer.
- Argon gas fill: Improves insulation.
- Tinted glass: Reduces glare and UV damage.
- Blinds/shades: Help regulate temperature.
High-quality energy-efficient skylights may cost more initially but save money over time.
Lifespan and Maintenance
A well-installed skylight lasts 15 to 25 years. Maintenance is important to extend lifespan and avoid problems.
Maintenance Tips:
- Inspect flashing annually.
- Clean skylight glass at least twice a year.
- Clear debris from roof around skylight.
- Check for interior water stains after storms.
Pros and Cons of Skylight Installation
Pros:
- Increases natural light
- Adds ventilation
- Improves home aesthetics
- Potential energy savings
- Boosts home resale value
Cons:
- Higher upfront cost
- Risk of leaks if not installed properly
- Potential heat gain/loss
- Requires roof cutting and reinforcement
- Ongoing maintenance
Cost Comparison: Skylights vs. Alternatives
If you’re hesitant about the cost to put in skylight, there are alternatives to consider:
- Solar Tubes: Less expensive, smaller light delivery.
- Larger Windows: Easier installation but limited by wall placement.
- Light Shelves: Redirect daylight but don’t create overhead light.
While alternatives have benefits, skylights provide unique overhead illumination that no other solution can fully replicate.
Real-Life Examples
Example 1: Tubular Skylight in a Hallway
- Total Cost: $850
- Labor: 1 day
- Result: Brighter hallway, minimal disruption.
Example 2: Motorized Venting Skylight in Kitchen
- Total Cost: $3,800
- Labor: 2 days + electrical wiring
- Result: Better light and airflow, energy-efficient model with rain sensor.
Example 3: Custom Oversized Skylight in Living Room
- Total Cost: $9,500
- Labor: 5 days including roof reinforcement and interior finishing
- Result: Dramatic centerpiece with stunning daylight.
Tips for Reducing Skylight Installation Costs
- Choose standard sizes – Custom units raise prices dramatically.
- Bundle with roof replacement – Adding skylights during reroofing is cheaper.
- Opt for fixed units – Venting models are more expensive.
- Get multiple quotes – Prices vary by contractor.
- Maintain your skylight – Proper care extends lifespan and avoids costly repairs.
Conclusion
Understanding the cost to put in skylight involves more than just the price tag of the unit. The total expense depends on the type of skylight, roof conditions, installation complexity, and finishing work. While costs can range widely—from a few hundred dollars for simple tubular skylights to over $10,000 for custom motorized designs—the benefits of natural light, improved aesthetics, and added ventilation often outweigh the investment.
For homeowners who want to brighten their living spaces and enjoy the unique charm of daylight streaming from above, skylights can be well worth the cost. With careful planning, choosing the right type, and hiring skilled professionals, you can enjoy a durable, beautiful skylight that enhances your home for decades to come.440-235-3124
