Skylights are a popular choice for homeowners looking to bring natural light into their homes and increase the overall aesthetic appeal. If you have a metal roof and are considering installing a skylight, you may be wondering if it’s possible and how to go about it. 

In this comprehensive guide, we will walk you through the process of installing a skylight on a metal roof, from choosing the right type of skylight to the installation itself. So let’s dive in and shed some light on this topic!

Types of Skylights for Metal Roofs

When it comes to skylights for metal roofs, there are two main types to consider: Light Transmitting Panels (LTPs) and Curb Mount Skylights. Each type offers its own unique advantages and considerations.

Light Transmitting Panels (LTPs)

LTPs are translucent panels that allow natural light to pass through. They can be used not only in metal roofs but also as accessories for metal wall panels. LTPs come in various profiles and can be custom-formed to match the configuration and characteristics of your metal roof system. This seamless integration ensures a visually appealing and functional skylight solution.

Curb Mount Skylights

Curb mount skylights feature a raised structure, known as a curb, that surrounds the roof opening where the skylight will be installed. These skylights come in different shapes and styles, providing versatility in design options. Curb mount skylights are secured to the curb, creating a watertight seal and ensuring proper installation.

Now that you have an understanding of the types of skylights available, let’s proceed to the next step of the installation process.

Planning the Skylight Placement and Orientation

Proper placement and orientation are crucial factors in maximising the benefits of your skylight. Consider the following aspects during the planning phase:

  • Light Obstructions: Identify any potential obstructions such as trees or nearby structures that could obstruct the natural light entering through the skylight. Choose a location that allows for unobstructed sunlight penetration.
  • Optimal Exposure: Take advantage of the sun’s path throughout the day and seasons. Consider the orientation of your skylight to optimise natural light and energy efficiency. For example, if you want to minimise heating costs during winter, position the skylight to capture the maximum sunlight during those months.
  • Safety Considerations: Ensure safety by installing metal railings or safety nets to prevent falls through the skylight. This is especially important during the installation process to protect workers and prevent accidents.

By carefully considering these factors, you can create a skylight placement and orientation that maximises the benefits and enhances the overall functionality of your metal roof.

Skylight Installation Process on a Metal Roof

The skylight installation process on a metal roof can be divided into several key steps. Let’s walk through each step to ensure a successful installation:

Step 1: Assess the Roof Structure

Before installing a skylight, it’s essential to assess the roof structure to ensure it can support the additional weight and accommodate the skylight. Consult with a professional roofer or structural engineer to determine the structural integrity of your roof.

Step 2: Choose the Right Skylight and Flashing System

Select a skylight and flashing system that is compatible with your metal roof type. Consider factors such as the profile of your metal roof panels, the required flashing dimensions, and the specific installation requirements provided by the skylight manufacturer.

Step 3: Prepare the Roof Opening

Measure and mark the desired location for the skylight on your metal roof. Carefully cut and remove the metal panels to create the roof opening. Ensure precise measurements to achieve a proper fit for the skylight.

Step 4: Install the Skylight

Follow the manufacturer’s instructions for installing the skylight and flashing system. Secure the skylight to the roof opening using the recommended fasteners. Ensure a watertight seal by properly aligning and attaching the flashing components.

Step 5: Test for Leaks

After the skylight installation, conduct a thorough leak test to ensure there are no water infiltrations. Use a hose to simulate rainwater and carefully inspect the skylight and surrounding flashing for any signs of leakage. Address any issues promptly to prevent further damage.

Step 6: Maintenance and Regular Inspections

Regularly inspect and maintain your skylight to ensure its longevity and optimal performance. Clear any debris or dirt from the skylight and check for any signs of damage or deterioration. Replace worn-out gaskets or seals as needed to maintain a watertight seal.

By following these steps and consulting with professionals when necessary, you can successfully install a skylight on your metal roof and enjoy the benefits of natural light and improved aesthetics.


Installing a skylight on a metal roof is a great way to enhance your home’s natural lighting, energy efficiency, and overall appeal. Whether you choose Light Transmitting Panels or Curb Mount Skylights, proper planning, and installation techniques are crucial for a successful outcome.

 By considering factors such as skylight placement, orientation, and safety, as well as following the step-by-step installation process, you can enjoy the beauty and functionality of a skylight on your metal roof for years to come. Remember, if you’re unsure about any aspect of the installation process, it’s always best to consult with experienced roofing professionals to ensure a safe and efficient installation.
