Before starting this roofing project, understanding the exact cost helps you plan a beautiful natural light upgrade that fits your home and budget.
Skylight Installation Cost Factors
Adding a skylight in St. Louis, MO, requires careful planning and the expertise of a local skylight installation professional. The total price of your project depends on the materials you select, the dimensions of the window, and the complexity of integrating it into your existing roof.
Type of Skylight
The design and functionality of the skylight you choose dictate the baseline material and labor expenses. Fixed units are straightforward to install, while vented or custom options require complex mechanisms and structural framing. In St. Louis, MO, homeowners pay an average of $1,931 for a complete installation, with most projects falling between $1,531 and $2,332. When selecting a model, you must account for the local climate, as extreme weather, heavy rain, and high winds demand high-quality seals and impact-resistant glass. A basic tubular skylight costs $860 to $2,000, making it a highly practical way to bring natural light into a hallway or closet. Conversely, a vented skylight ranges from $1,430 to $3,330 and provides essential airflow to combat humid summer days. Before cutting into your ceiling, we recommend scheduling a professional roof inspection to ensure your structure can support the new addition. Factoring in the roof inspection cost upfront prevents unexpected structural repairs later.
| Skylight Type | Description | Local Cost Range | National Cost Range |
|---|---|---|---|
| Fixed | Does not open; basic natural light | $1,150–$2,290 | $1,200–$2,400 |
| Vented | Opens for airflow; manual or motorized | $1,430–$3,330 | $1,500–$3,500 |
| Tubular | Small, round; channels light with a reflective tube | $860–$2,000 | $900–$2,100 |
| Custom | Made-to-order sizes or shapes | $2,380–$5,240+ | $2,500–$5,500+ |
Skylight Size
Larger skylights demand more materials, extensive roof modifications, and additional labor hours, directly increasing your total bill. Expanding the opening also requires extra structural reinforcement to maintain the integrity of your roof. For a compact 10- to 14-inch unit, expect to spend $860 to $1,530 for the installation. If you want a dramatic architectural feature, a custom 48- to 72-inch skylight costs $2,380 to $4,760 or more. When installing oversized glass in St. Louis, MO, you must ensure the unit features proper thermal ratings to handle intense heat waves and winter ice storms. Upgrading your surrounding attic insulation helps maintain your home's energy efficiency after cutting a large hole in the roof envelope. Reviewing local attic insulation costs during the planning phase ensures your HVAC system will not have to work overtime to regulate indoor temperatures.
| Skylight Size (In.) | Description | Local Cost Range | National Cost Range |
|---|---|---|---|
| 10–14 | Tubular or compact fixed; great for hallways or closets | $860–$1,530 | $900–$1,600 |
| 22–46 | Standard fixed or vented; ideal for bedrooms or kitchens | $1,430–$2,570 | $1,500–$2,700 |
| 48–72 | Custom or oversized; for living rooms or great rooms | $2,380–$4,760+ | $2,500–$5,000+ |
Demolition and Prep
Preparing the installation site involves removing existing roofing materials, cutting the roof deck, and framing the new opening. Complex roof structures or multiple layers of old shingles require more time and labor, driving up the initial preparation expenses. In St. Louis, MO, contractors must carefully flash and seal the new opening immediately to protect your home from sudden storms and heavy rain that lead to indoor flooding. If your roof deck shows signs of rot or water damage during the demolition phase, the installation crew must replace the compromised wood before proceeding. We also suggest performing routine gutter cleaning to ensure proper water drainage away from the newly installed flashing. Keeping water flowing off the roof prevents pooling around the skylight and protects your interior from leaks.
Skylight Installation Pro Costs
Hiring a pro in St. Louis, MO, ensures your new window is secure and watertight. Labor for a standard skylight installation runs $500 to $1,500 per project, depending on roof pitch and structural complexity. If your design requires modifying the roof framing, you must hire a carpenter for an additional $300 to $800. Adding motorized shades requires an electrician, costing $50 to $120 per hour. We recommend securing multiple quotes to find the best rates.
Licensing
Before hiring a skylight installation professional, verify they hold the required skylight installation license for Missouri or St. Louis, and ask for proof of liability insurance and workers' comp if they have employees. Hiring an unlicensed skylight installation professional can leave you with little protection if something goes wrong and may make it harder to recover payments or hold them accountable. To verify the type of licensing required, visit the Missouri government's official licensing board website for more information.
Permits
Before starting skylight installation, confirm whether your project requires permits in your area and who is responsible for obtaining them. Permit requirements and costs vary by location, but most skylight installation permits range from $50 to $400, depending on the scope of work and your local municipality.
Working without the proper permits can lead to fines, project delays, or complications when selling your home. If you're hiring a skylight installation professional, review your contract to ensure they will handle the permitting process and inspections. To verify permit requirements, visit your city or county's official building department website for the most accurate and up-to-date information.

Roof works. One of the skylights leaks, Rich has been super responsive in post install issues. He's been out twice trying to fix it. Next step is to replace it with a new one. Even with this one issue, I give them an "A", and I don't think I would use anyone else for a flat roof. This is a...
