Skylight Installation Tips: Brighten Your Space and Boost Your Home's Efficiency


When it comes to home lighting, natural light is often considered the best form of illumination. A skylight is an ideal solution to harness natural sunlight to brighten up a room, maximize energy efficiency, and improve ventilation. Here, we will share essential tips and tricks that will help you carry out a successful skylight installation, and make your home a brighter, more vibrant living space.

1. Choose the Right Skylight for Your Home

The type of skylight you choose for your home will depend on its size, style, and specific needs. Before purchasing a skylight, research and familiarize yourself with the wide range of options available in the market. Common types of skylights include fixed, vented, and tubular skylights, each offering distinct benefits.

Fixed skylights are a popular option, as they don't open, ensuring minimal leakage problems and heat loss. Vented skylights, on the other hand, can be opened to create natural ventilation and are ideal for rooms that need improved airflow. Tubular skylights are perfect for smaller rooms, hallways, and other spaces with insufficient ceiling space, as they are compact and easy to install.

2. Determine the Ideal Skylight Location

Finding the right position for your skylight is crucial to capturing maximum sunlight throughout the day. Keep in mind that the sun's path varies depending on your geographic location and the time of year. For homes in the northern hemisphere, south-facing skylights will receive the most sunlight, while those in the southern hemisphere will benefit more from north-facing skylights.

It's also essential to consider your roof's slope when determining the skylight location. A well-positioned skylight should be installed at a degree that matches your roof's pitch to minimize water and debris buildup and ensure optimal performance.

3. Take into Account the Size of the Skylight

Selecting the right size for your new skylight is vital to ensure both aesthetic and functional harmony with the rest of your home. Bigger skylights may provide more light, but they can lead to overheating in the room below and increase energy costs. On the other hand, a skylight that is too small may not provide the desired amount of natural light and impact its efficiency.

To find the right balance, use the "5- to 10-percent rule," which entails ensuring that the size of the skylight opening is 5 to 10 percent of the room's total floor space. This will help you optimize the amount of sunlight streaming in, while also ensuring proper insulation and reduced energy costs.

4. Choose an Energy-Efficient Skylight

Skylights can have a significant impact on your home's energy efficiency. When selecting a skylight, opt for an energy-efficient model that has a low U-value and high solar heat gain coefficient (SHGC). U-value measures the rate of heat transfer, while SHGC indicates how well a skylight blocks heat from sunlight. Consult with your skylight manufacturer or an expert for the best energy-efficient options.

5. Proper Flashing Installation Is Crucial

To achieve a leak-free skylight installation, make sure to install proper flashing around the skylight's perimeter. Flashing is essential to keeping water out of the roof opening, as it prevents leaks and ensures a watertight seal. An experienced professional can recommend the right flashing materials, such as metal or rubber, that will work best for your roof type and climate.

6. Employ Professional Installation Services

While it's possible to take on skylight installation as a DIY project, hiring a reputable professional installer or a lighting professional will save you time, effort, and potential mistakes, while ensuring a safe and successful installation outcome. Professional installation services will also help you avoid electrical safety hazards and tackle light fixture issues more effectively.

7. Pair Your Skylight with Complementary Light Fixtures

To achieve a balanced and functional lighting design, don't rely solely on the natural light from your skylight. Pair your skylight with complementary artificial light fixtures, such as pendant lights or chandeliers, which will ensure proper illumination during nighttime and cloudy days.

8. Regular Maintenance Is Necessary

To keep your skylight in optimal condition, it's crucial to carry out regular maintenance. Check for possible leaks and clean the skylight glass to ensure it remains free from debris, dirt, and soot, which might otherwise hinder the passage of light. For vented skylights, inspect the hinges and other moving parts to ensure smooth operation and lubricate them if necessary.

In conclusion, installing a skylight in your home not only provides natural light and enhanced ventilation but can also result in cost savings due to increased energy efficiency. Keep these skylight installation tips in mind to ensure a successful, aesthetically pleasing, and energy-efficient addition to your living space.

Frequently Asked Questions

Below are some commonly asked questions regarding skylight installations.

What are the tips for skylight placement?

  1. Consider the sun's path and your home's orientation by placing skylights on the south-facing side in the northern hemisphere and the north-facing side in the southern hemisphere for maximum sunlight exposure.
  2. Ensure the angle of the skylight matches your roof's pitch to minimize water and debris buildup.
  3. Consider the room's layout and ensure the skylight is placed in a position that would provide even distribution of natural light.

What is the rule of thumb for skylights?

The "5- to 10-percent rule" is a general guideline to help you size your skylight. This rule suggests that the size of the skylight opening should be between 5% and 10% of the room's total floor space. This ensures that the right amount of sunlight is allowed into the room while maintaining proper insulation and reduced energy costs.

What is the spacing for skylights?

There's no one-size-fits-all answer to this question, as the optimal spacing for skylights depends on various factors, including the size of the room, the number of skylights, and the overall structure of your home. A good rule of thumb is to space them evenly in a room to distribute natural light evenly. Consulting with a skylight professional or a lighting professional can help you determine the ideal spacing for your specific settings.

What side of the house is best for skylight?

The best side for a skylight depends on your home's location. For homes in the northern hemisphere, it's often best to install skylights on the south-facing side to capture the most sunlight. Conversely, in the southern hemisphere, the north-facing side is more optimal. The ultimate goal is to maximize the amount of natural light entering the room while minimizing heat loss and overheating issues.
