In this ultimate showdown, we will compare the advantages and disadvantages of both curb mount and deck mount skylights, helping you make an informed decision for your home.

Curb Mount Skylights:


Energy Efficiency:

Curb mount skylights are designed to be mounted on a raised curb, which provides an extra layer of insulation. This design helps in reducing heat loss during the winter and heat gain during the summer, making them more energy-efficient than their deck mount counterparts.

Leak Resistance:

The raised curb of curb mount skylights acts as a barrier to prevent water infiltration, which can be especially important in areas prone to heavy rainfall or snow. This design minimizes the risk of leaks and water damage.


Curb mount skylights are versatile and can be installed on a wide range of roofing materials, including shingles, metal, and single-ply membranes. This versatility makes them suitable for various roof types and construction styles.

Aesthetic Appeal:

Curb mount skylights often have a more aesthetically pleasing appearance as they sit above the roofline, providing a sleek and modern look. This can enhance the overall curb appeal of your home.


Higher Installation Costs

: Installing curb mount skylights typically requires more time and labor, which can result in higher installation costs. Additionally, the need for a raised curb structure may increase construction expenses.

Limited Placement Options:

The design of curb mount skylights may limit the placement options on your roof. The raised curb requires adequate clearance, which can be challenging in some architectural designs.

Deck Mount Skylights:


Lower Installation Costs:

Deck mount skylights are typically easier and quicker to install, which can lead to cost savings on labor and materials. This makes them a budget-friendly option for homeowners.

Simplified Flashing:

Deck mount skylights have a simpler flashing system, which can reduce the risk of installation errors and potential leaks. This design makes them more forgiving during the installation process.

Flexible Placement:

Deck mount skylights can be placed on a variety of roof types and angles without the need for a raised curb. This flexibility in placement allows for more creative and customized designs.


Lower Energy Efficiency:

Deck mount skylights typically have less insulation around the frame due to their flush installation with the roof. This can result in higher heat transfer, potentially affecting your home’s energy efficiency.

Increased Risk of Leaks:

While the flashing system is simpler, deck mount skylights are more susceptible to leaks if not installed correctly or if the roofing materials degrade over time.

Aesthetic Limitations:

Deck mount skylights may not have the same sleek and modern look as curb mount skylights, as they sit flush with the roofline. This may be less appealing to those who prioritize aesthetics.Curb Mount Skylight vs. Deck Mount

In the ultimate showdown between curb mount and deck mount skylights, the choice ultimately depends on your specific needs and preferences. If energy efficiency and leak resistance are top priorities, curb mount skylights may be the better option. On the other hand, if you’re working within a budget and value flexibility in placement, deck mount skylights might be the way to go.

It’s crucial to consult with a professional installer or roofing expert to determine the best skylight solution for your home. They can provide guidance tailored to your specific roofing material, climate, and design preferences. Regardless of your choice, skylights can bring the beauty of the outdoors inside your home, providing natural light and a connection to the sky above.
