  • Long-lasting durability: The robust design and proper installation of curb-mounted skylights ensure durability and resistance to harsh weather conditions.

If you’re considering installing a skylight, curb-mounted skylights offer numerous benefits and can transform the look and feel of your home. Consult with a professional contractor to determine the best option for your specific roof type and design goals.

Deck-Mounted Skylights

Deck-mounted skylights offer a sleek and integrated look, as they are directly attached to the roof deck. They do not require a separate curb and have a lower profile compared to curb-mounted skylights. The installation process involves cutting an opening in the roof deck and fastening the skylight frame directly to it. Deck-mounted skylights are easier to install and offer excellent waterproofing when installed with matching cladding and flashing kits.

Key Differences Between Curb and Deck Mounted Skylights

When it comes to skylights, choosing between curb-mounted and deck-mounted options can significantly impact both the installation process and the overall aesthetic of your home. Understanding the key differences between these two types is essential in making an informed decision. Let’s take a closer look at the distinctive features of each.

Difference in Installation

  • Curb-mounted skylights: These skylights require the construction of a curb on the roof deck. The curb serves as the foundation for the skylight and elevates it above the roof’s surface. The installation process includes building the curb and then attaching the skylight to it using flashing kits for a watertight seal.
  • Deck-mounted skylights: These skylights are directly attached to the roof deck without the need for a separate curb. The installation involves cutting an opening in the roof deck and securing the skylight frame directly to it. Matching cladding and flashing kits ensure seamless integration and waterproofing.

Aesthetic Impact

The choice between curb-mounted and deck-mounted skylights can also affect the overall look of your roofline:

Curb-mounted skylights typically have a higher profile and may alter the silhouette of the roof, making them more visible from the exterior. This can add a distinctive architectural element to your home’s design.

On the other hand, deck-mounted skylights offer a lower profile and a more integrated look with the roofline. They blend seamlessly with the roof, creating a sleek and modern appearance.

Determining Factors

When deciding between the two options, consider the following factors:

  • The specific roof type and pitch: Curb-mounted skylights are more suitable for flat roofs or those with a low pitch, while deck-mounted skylights require a sufficient pitch for proper drainage.
  • Aesthetic preferences: If you prefer a more prominent skylight with architectural impact, curb-mounted skylights may be the better choice. If you prefer a streamlined and integrated look, deck-mounted skylights are likely to align with your vision.

Summary

In summary, the main differences between curb-mounted and deck-mounted skylights lie in their installation process and aesthetic impact. Curb-mounted skylights require the construction of a curb and offer a higher profile, while deck-mounted skylights are directly attached to the roof deck and provide a lower profile. The choice ultimately depends on the specific roof type and personal aesthetic preferences.

Skylight Flashing

Flashing is a critical component in skylight installation, ensuring a watertight seal and secure integration with the roofing material. Proper installation of flashing is essential to prevent leaks and maintain the durability of the skylight.

When it comes to skylight flashing, there are specific considerations for both curb-mounted and deck-mounted skylights.

“Flashing is like the armor that protects your skylight from the elements. It ensures that rain and moisture stay outside while allowing natural light to illuminate your space.”

Curb-Mounted Skylight Flashing

Curb-mounted skylights require flashing around the base of the curb to create a tight seal. This flashing acts as a barrier between the skylight and the roof, preventing water from seeping inside. The flashing kits for curb-mounted skylights typically include all the necessary components, such as the base flashing, step flashing, and counter flashing.

The base flashing is installed at the bottom of the curb and serves as the primary waterproofing layer. It is important to ensure that the base flashing is properly sealed to the roof deck to prevent any water penetration.

The step flashing, which is installed along the sides of the curb, provides additional protection against water infiltration. It overlaps the base flashing and diverts any water away from the skylight, helping to keep it dry.

Lastly, the counter flashing is installed over the step flashing and is designed to cover the exposed edges. It acts as a final layer of defense, preventing any water from entering through the sides of the skylight.

Deck-Mounted Skylight Flashing

Deck-mounted skylights require flashing that integrates seamlessly with the roof deck. The flashing kits for deck-mounted skylights are designed to create a watertight seal around the skylight frame.

The flashing is typically installed in layers, starting with the base flashing. This flashing is attached directly to the roof deck and provides the initial barrier against water intrusion. The base flashing should be securely fastened to ensure a tight fit.

Next, step flashing is installed along the sides of the skylight frame, overlapping the base flashing. This step flashing helps divert any water away from the skylight, channeling it down the roof surface.

The final layer of flashing for deck-mounted skylights is the counter flashing, which is installed over the step flashing. The counter flashing protects the exposed edges of the skylight frame and provides an extra layer of defense against water infiltration.

Flashing Curb-Mounted Skylights Deck-Mounted Skylights
Base Flashing Installed around the base of the curb Attached directly to the roof deck
Step Flashing Installed along the sides of the curb Installed along the sides of the skylight frame
Counter Flashing Installed over the step flashing Installed over the step flashing
