If you are looking for natural light in your home, you may wonder whether a sun tunnel or skylight is the right choice. Both options have benefits and detriments, so deciding the best option for your needs can be challenging. Spennato Family Roofing will discuss the pros and cons of sun tunnels and skylights to determine which option is best for you!

Sun Tunnels

Sun tunnels are a great solution if you are looking for an economical way to add natural light to your home. They are also known as tubular skylights or solar tubes. Sun tunnels are typically made from a transparent or translucent material, such as acrylic or fiberglass, and are mounted on your roof. The tube is typically 10-14 feet long and is lined with a reflective material, such as aluminum, to maximize the amount of light transmitted into your home.

Sun tunnels are less expensive than skylights and can be installed without professional help. They have two main types: rigid and flexible. Rigid sun tunnels are made from metal or glass and are more expensive than flexible sun tunnels, but they are also more durable and have less chance of leaking. Flexible sun tunnels are made from plastic and are less costly than rigid sun tunnels, but they are not as durable and may leak if not installed correctly.

When choosing a sun tunnel for your home or building, you must consider the size of the room you want to add light to and the climate in your area.

Benefits of Sun Tunnels

1. Reduced Energy Costs

Sun tunnels are designed to let natural light into the home or building, which reduces saving energy by keeping your home or building cooler in the summer months by dissipating heat away from the interior.

2. Improve Air Quality

In addition to reducing energy costs, sun tunnels can also improve the indoor air quality of a home or building by allowing fresh air to circulate, elevating your mood.

3. Add Value to Your Home

They add value to your home or building, as they are an attractive feature that potential buyers will look for.

4. Enhance Your Home’s Interior

They lift your home’s interior and make it feel more open and spacious.

5. Easy-to-Install

They are easy to install and can be done by a professional or as a do-it-yourself project.

Drawbacks of Sun Tunnels

However, sun tunnels have a few drawbacks you should be aware of before deciding. First, sun tunnels can leak air and let in pests if not correctly installed. Second, sun tunnels do not provide as much light as skylights, so they may not be the best solution if you want to brighten up a dark room.


Skylights are more expensive than sun tunnels, but they offer many benefits that make them worth the investment. They are made from glass or plastic and are mounted on your roof.

Skylights are a good option for bringing natural light into your home because they provide a wide area of coverage and can be customized to fit the specific needs of your home. They release significantly more light than sun tunnels and are less likely to leak air or let in pests.

Skylights vary in size and shape and can be either fixed or operable (openable). They can be opened to vent hot air from your home, making them an excellent choice for homes in warm climates.

Benefits of Skylights

1. More Natural Light

One of the primary benefits of skylights is that they provide more natural light. Natural light has several benefits, including reducing eye strain, increasing productivity, and boosting mood. Skylights add natural light to your home, typically larger than traditional windows.

2. Increased Ventilation

Skylights can also help to increase ventilation in a space. Opening up a skylight allows fresh air to enter the room, which can help improve the air quality. Additionally, increased ventilation can help to reduce mold and mildew growth.

3. Reduced Energy Costs

Another benefit of skylights is that they can help reduce energy costs. In the winter, skylights allow sunlight to enter the room, which can help to heat the space naturally. In the summer, you can open the skylights to help ventilate the area and keep it cool.

4. Improved Aesthetics

Skylights can also improve the aesthetics of a space. They add a unique element to a room’s design and can help create a bright and open feel. Additionally, skylights can help bring the outdoors inside, making you feel more connected to nature.

5. Increased Value

Skylights can also boost the value of your home. Homes with skylights are often more desirable than those without, as they offer all the above benefits. If you sell your home in the future, adding skylights could be a great way to boost its value.

6. Improved Energy Efficiency

Skylights are also more energy efficient than traditional windows, as they keep heat in during the winter and out during the summer. It can further help to reduce your energy costs and make your home more environmentally friendly.

7. Greater Privacy

Another benefit of skylights is that they provide greater privacy than traditional windows, as no one from the outside can sneak in or watch what’s happening inside your home. Skylights are a good option for your home if privacy concerns you.

What is better, Sun Tunnel or Sky Light?

So, which option is right for you? A sun tunnel may be the way to go if you’re looking for an affordable alternative to add natural light to your home. However, if you desire more exposure to sunlight and ventilation, then skylights are the better choice. Whichever option you choose, get it installed by a professional to ensure that it functions properly.
