Choosing between a curb-mounted and a deck-mounted skylight can significantly impact your home's aesthetic appeal, energy efficiency, and overall structural integrity. This comprehensive guide will delve into the key differences, advantages, and disadvantages of each type, helping you make an informed decision.
What is a Curb-Mounted Skylight?
Curb-mounted skylights are installed on a curb, a pre-fabricated frame that's built into the roof structure during construction or major renovations. This curb provides a secure and weathertight base for the skylight unit. Think of it like a built-in frame for your skylight.
Advantages of Curb-Mounted Skylights:
- Superior Weather Resistance: The curb creates a significant barrier against water leaks, making curb-mounted skylights exceptionally reliable in harsh weather conditions.
- Increased Insulation: The curb provides additional insulation, improving energy efficiency and reducing heat loss or gain.
- Heavier Skylights: The sturdy curb supports larger and heavier skylights, opening up more options for size and design.
- Better Flashing: Flashing, the crucial waterproof seal around the skylight, is easier and more effectively installed with a curb-mounted system.
Disadvantages of Curb-Mounted Skylights:
- More Expensive: The added cost of the curb and the more complex installation process typically make curb-mounted skylights more expensive.
- Requires Construction: Installation often requires significant roof work, potentially causing disruption during the construction or renovation process.
- Less Flexibility: Installing a curb limits the placement flexibility of the skylight to the location of the pre-built curb.
What is a Deck-Mounted Skylight?
Deck-mounted skylights are installed directly onto the roof deck, eliminating the need for a separate curb. They're simpler to install and are often a more cost-effective choice.
Advantages of Deck-Mounted Skylights:
- Lower Cost: Generally less expensive due to simpler installation and fewer materials.
- Easier Installation: Installation is less disruptive, faster, and easier, often suitable for DIY projects (though professional installation is always recommended).
- Greater Flexibility: Can be installed in almost any location on the roof, offering more placement options.
Disadvantages of Deck-Mounted Skylights:
- Less Weather Resistance: The lack of a curb makes them potentially more susceptible to leaks, especially in areas with heavy rainfall or snow.
- Smaller Sizes: The structural support from a curb is absent; therefore, deck-mounted skylights are usually smaller.
- More Difficult Flashing: Proper flashing is crucial for preventing leaks, requiring meticulous attention to detail during installation.
Which Type of Skylight is Right for You?
The best choice depends on your specific needs and circumstances:
- Choose Curb-Mounted if: You prioritize weather resistance, energy efficiency, and plan to install larger skylights. You're willing to invest more in initial costs and potentially tolerate more disruption during installation.
- Choose Deck-Mounted if: Budget is a primary concern, you need a quicker and simpler installation process, and have some experience with DIY projects. Smaller skylights and flexibility of placement are also important factors.
How Much Does a Curb Mounted Skylight Cost?
The cost of a curb-mounted skylight varies significantly depending on size, materials, and installation complexity. Expect to pay more than for a deck-mounted option, with costs potentially ranging from several hundred to several thousand dollars.
How Much Does a Deck Mounted Skylight Cost?
Similar to curb-mounted skylights, the cost of deck-mounted skylights depends on size, materials, and installation. However, you should anticipate a lower price point compared to curb-mounted alternatives.
Can I Install a Skylight Myself?
While some homeowners attempt DIY installation, especially with deck-mounted skylights, professional installation is strongly recommended. Improper installation can lead to leaks, structural damage, and void warranties. A professional installer has the expertise and experience to ensure proper flashing and weather sealing.
What are the Different Types of Skylights?
Beyond the mounting method, skylights come in various styles (fixed, venting, tubular), materials (glass, plastic), and designs to complement your home's architecture. Choosing the right skylight involves several considerations beyond just the mounting type.
By carefully considering these factors, you can choose the skylight that best meets your needs and enhances your home for years to come. Remember to consult with a qualified roofing professional to discuss your specific requirements and get professional advice.
