Adding a skylight can dramatically transform a room, flooding it with natural light and creating a sense of spaciousness. However, the installation method significantly impacts the project's complexity, cost, and the overall aesthetic. This guide compares curb-mounted and deck-mounted skylights, helping you choose the best option for your home.
What is a Curb-Mounted Skylight?
Curb-mounted skylights are installed into a pre-built curb, a framed structure that sits on the roof deck. This curb provides a support base for the skylight and creates a weathertight seal. Because the curb is installed before the skylight, it allows for a more seamless integration into the roofline and offers several advantages.
Advantages of Curb-Mounted Skylights:
- Superior Weather Protection: The curb acts as a barrier against the elements, providing exceptional weather resistance and preventing leaks.
- Increased Insulation: The space between the curb and the skylight allows for better insulation, minimizing heat loss in winter and heat gain in summer.
- Larger Skylight Options: Curb-mounted systems can accommodate larger skylights, maximizing light intake.
- Improved Aesthetics: Often considered more aesthetically pleasing, particularly on sloped roofs, due to a cleaner, more integrated look.
What is a Deck-Mounted Skylight?
Deck-mounted skylights are installed directly onto the roof deck, without the need for a pre-built curb. This simplifies the installation process, making it a quicker and sometimes less expensive option.
Advantages of Deck-Mounted Skylights:
- Simpler Installation: Generally quicker and easier to install, potentially reducing labor costs.
- Cost-Effective: Often a less expensive option upfront due to the absence of the curb.
- Suitable for Flat Roofs: Particularly well-suited for flat roofs where curb installation might be challenging.
Curb-Mounted vs. Deck-Mounted: Which is Right for You?
The best choice depends on several factors:
- Roof Type: Curb-mounted skylights are ideal for sloped roofs, while deck-mounted are better suited for flat roofs.
- Budget: Deck-mounted systems are typically less expensive upfront, but curb-mounted offer long-term cost savings due to improved insulation and weather protection.
- Skylight Size: Larger skylights generally require curb mounting for stability and weather resistance.
- Aesthetic Preferences: Curb-mounted systems often integrate more seamlessly into the roofline, creating a more polished look.
What are the Different Types of Skylight Flashing?
Skylight flashing, regardless of whether it's curb or deck-mounted, is crucial for preventing leaks. Different flashing systems exist, often depending on the roof material and the skylight manufacturer. It's vital to select a flashing system compatible with your roof and skylight to ensure a watertight seal. Professional installation is always recommended to ensure correct flashing installation.
What is the Best Way to Install a Skylight?
While DIY installation is possible, especially for deck-mounted options, professional installation is highly recommended, particularly for curb-mounted skylights. Improper installation can lead to leaks, structural damage, and void warranties. A qualified installer possesses the expertise and tools to ensure proper flashing, sealing, and integration with your roof.
How Much Does it Cost to Install a Skylight?
The cost of skylight installation varies significantly based on several factors: the type of skylight (curb-mounted or deck-mounted), the skylight's size, the complexity of the installation (roof type, accessibility), and the cost of labor in your region. Getting multiple quotes from reputable installers is crucial for obtaining accurate pricing.
How Long Does it Take to Install a Skylight?
Installation time depends on factors similar to cost – the type of skylight, its size, and the complexity of the installation. A simple deck-mounted skylight might take a day, while a complex curb-mounted installation on a steep roof could take several days.
Choosing between a curb-mounted and deck-mounted skylight requires careful consideration of your specific needs and circumstances. By understanding the advantages and disadvantages of each option, you can make an informed decision that maximizes both functionality and aesthetics. Remember to consult with a qualified roofing professional for personalized advice and a professional installation.
