1. What Is a Skylight?
A skylight is a window installed in the roof or ceiling of a building to allow natural sunlight to enter interior spaces. Skylights are typically installed in areas like kitchens, bathrooms, attics, or living rooms to:
- Brighten dark interiors
- Reduce electricity usage
- Improve airflow and ventilation
- Enhance interior aesthetics
There are three main types of skylights: fixed, vented, and tubular. Each offers different functionality, installation complexity, and cost.
2. Why Homeowners Install Skylights
Skylights are more than just a pretty feature—they deliver tangible benefits that justify the investment. Here’s why many homeowners choose to add them:
- Natural Light: Increases brightness, especially in rooms with limited wall space.
- Energy Efficiency: Reduces the need for artificial lighting, saving on electricity.
- Ventilation: Vented skylights let hot air escape, cooling the home naturally.
- Property Value: A well-installed skylight can enhance resale value and curb appeal.
- Well-being: Natural light boosts mood, productivity, and sleep quality.
But how much do these benefits cost? Let’s explore.
3. Average Cost of Installing Skylight

- Low-end: $800 – $1,200
- Mid-range: $1,500 – $2,500
- High-end (custom or motorized): $3,000 – $5,000+
These costs include materials, labor, and basic flashing kits. However, total price can vary depending on location, roof structure, skylight size, and features.
4. Factors That Influence Skylight Installation Costs
Several variables will impact the cost of installing skylight windows:
1. Type of Skylight
- Fixed vs. vented vs. tubular (more below)
2. Skylight Size
- Larger units require more framing, roofing work, and flashing
3. Roof Pitch and Material
- Steep or complex roofs (e.g., tile, slate) increase labor difficulty
4. Interior Ceiling Type
- Vaulted ceilings may reduce cost
- Attic conversions or drop ceilings add complexity
5. Location of Skylight
- Kitchens and bathrooms may require moisture-resistant materials
- Homes in hot climates may need solar-glazing or UV protection
6. Labor Rates
- Urban areas often have higher contractor costs than rural locations

6. Cost Comparison: Fixed vs. Vented vs. Tubular
Fixed Skylight Costs
- Most affordable option
- Ideal for hallways, closets, and low-moisture areas
- Lower maintenance, no moving parts
Vented Skylight Costs
- Adds functionality but increases price
- Great for bathrooms or kitchens
- Manual vented: cheaper, but less convenient

Tubular Skylight Costs
- Budget-friendly, minimal footprint
- Best for small spaces like pantries or powder rooms
- Easy to install, minimal roof alteration
7. Labor Costs: DIY vs. Professional Installation
DIY Skylight Installation Cost:
- Materials only: $300–$1,200
- Time: 10–20 hours
- Risk: High (leaks, structural damage, voided warranties)
Professional Installation:
- Total cost: $800–$3,500+ depending on scope
- Time: 1–3 days

Unless you have roofing and carpentry experience, professional installation is strongly recommended.
8. Skylight Installation in New vs. Existing Roofs
New Roof Installation
- Easier and cheaper to add skylight before shingles are installed
- May save $500–$800 on installation costs
Retrofit in Existing Roof
