Can you install skylights on a metal roof?

Yes, you can install skylights and windows in metal roofs.

In fact, this is an extremely popular addition to metal roofs. Not only do skylights enhance your indoor spaces, but our customers love the contrast between sleek, modern metal roofs, and a view into the great outdoors.

However, if you are looking to add a skylight to your metal roof, then there are a number of factors that you need to consider. We’ll cover these in more detail below.

What do you need to consider before installing skylights on a metal roof?

• The pitch of your roof – as your skylight will need to be compatible with the pitch of your roof (your roofing supplier will be able to guide you on this point). However, if the pitch of your roof is too low, then in periods of heavy rain, water ingress can occur in the seams. As a result, your roof will need to achieve the minimum pitch requirements and, if your roof is at a low pitch, then water will need to be managed effectively.
• The width of your intended skylight – there are width limits for skylights, which vary based on the size and structure of your metal roof. The skylight cannot be so wide that it exceeds more than a certain number of seams, as this will cause issues with water drainage.
• The depth of your roof – you can either choose a skylight that sits flush against your roof, or is sunken into the roof. However, these options are dependent on the depth of your roof, as a sunken skylight requires the metal roof to be of a specific minimum depth.

Beyond this, there are also design points for you to consider. Firstly, you will need to determine the type of skylight you would like. There is a wide range of different skylights, each one offering its own unique advantages, size, and price point.

Then, you will need to consider the design of your roof, as skylights also come in a variety of design styles. So, look for an option that suits the aesthetic of both your metal roof and the rest of your property.

What is the installation process for adding skylights to a metal roof?

The typical process for installing skylights to a metal roof is as follows:

1. Inspecting the metal roof – to identify any potential issues, then determine its depth and pitch, and the maximum width for a skylight.

2. Installing flashing and waterproofing – flashing is then installed in the area where the skylight will sit, before creating a watertight seal around the area.

3. Cutting open the roof – the area for the skylight will then be measured, before cutting through the panels.

4. Installing the frame – the frame is then fixed into the opening. Finally, watertight sealants and other finishing performance materials are added.
