5 Things You Need to Know About Installing Skylights and Sun Tunnels

Skylights and sun tunnels are fantastic additions to any home, bringing natural light into spaces that otherwise might remain dim. They can transform the atmosphere, making rooms feel more open and inviting. However, installing these features involves more than just cutting a hole in the roof and popping in a window. Feeney Roofing brings you a list of five things you must know before you install skylights or sun tunnels.

1. Curb-mounted Skylights vs Deck-mounted Skylights

There are two primary types of skylights: curb-mounted and deck-mounted. While they both light up your interior, they have their differences.

Curb-Mounted Skylights

Curb-mounted skylights sit on a raised frame, or “curb,” that is built onto your roof. This frame provides extra height, which can be beneficial for roofs with low slopes. One significant advantage of curb-mounted skylights is that they are less prone to leaking because the raised curb helps to direct water away from the window.

Deck-Mounted Skylights

Deck-mounted skylights, on the other hand, are installed flush with the roof, providing a sleek, integrated look. They are typically easier to install since they don’t require the additional step of building a curb. However, they need precise installation and proper sealing to prevent leaks.

2. Location, Location, Location

Where you install your skylight or sun tunnel is just as important as the type you choose. Here’s what to consider:

Roof Slope and Orientation

The slope and orientation of your roof affect the amount of light that will enter your home. Skylights on south-facing roofs capture more sunlight, which is great for bringing in lots of natural light but can also lead to overheating. North-facing skylights provide softer, more diffused light, which is ideal for spaces where you want consistent, moderate lighting.

Room Use

Consider how the room is used. For example, a kitchen can benefit from bright, direct light, whereas a bedroom might need a softer, more ambient light to create a restful environment. Sun tunnels are perfect for small, enclosed spaces like hallways or closets, where traditional skylights might not be practical.

3. Call a Team of Professionals to Handle the Installation

Installing skylights and sun tunnels properly is important to avoid common issues like leaks and drafts (and leaks can become a real pain). Call Feeney Roofing to install your skylights/sun tunnels. Our installation teams guarantee trouble-free skylights and sun tunnels. Feeney Roofing’s installation process involves:


Waterproofing is one of the most important aspects of skylight installation. We ensure that flashing and sealing materials are used correctly to prevent water from seeping in around the edges. Using high-quality flashing kits designed for your specific skylight model can make a big difference.


We insulate around your skylight or sun tunnel to help prevent heat loss in the winter and heat gain in the summer. Proper insulation also prevents condensation from forming, which can lead to mold and mildew problems.

4. Consider Energy Efficiency

Skylights and sun tunnels can have a significant impact on your home’s energy efficiency. Here’s what to keep in mind:

Glazing Options

Skylights come with various glazing options, such as double or triple glazing, which can improve insulation and energy efficiency. Low-E (low emissivity) coatings help reduce heat transfer, keeping your home cooler in the summer and warmer in the winter.


Some skylights offer ventilation options, which can help keep your home cool. Ventilated skylights can be opened to allow hot air to escape, reducing the need for air conditioning. This feature is particularly useful in kitchens and bathrooms, where heat and humidity levels can rise quickly.

Sun Tunnels

Sun tunnels are incredibly efficient at bringing light into your home with minimal heat transfer. They use reflective tubing to channel sunlight from the roof into your living space, making them a great choice for small or windowless areas where a traditional skylight isn’t feasible.

5. Maintenance and Durability

Once installed, skylights and sun tunnels require regular maintenance to ensure they continue to perform well. Here’s what you need to know:


Skylights can accumulate dirt, leaves, and other debris, which can block sunlight and reduce efficiency. Regular cleaning, both inside and out, will keep them clear and functional. Some modern skylights have self-cleaning glass, which can minimize maintenance needs.

Inspecting Seals and Flashing

Periodically inspect the seals and flashing around your skylights and sun tunnels to ensure they remain intact. Weather changes and temperature fluctuations can cause materials to expand and contract, potentially leading to leaks if not maintained properly.

Replacing Components

Over time, components like seals, gaskets, and even the glass itself may need replacing. Stay on top of these maintenance tasks to avoid larger issues and ensure the longevity of your installation.
