Want to install a roof window? Here are 8 steps to help you get started

Roof windows are a great way to transform your space with natural light. Letting more light into your room allows you to convert unused attics or underlit places into beautiful, usable spaces. It’s a common myth that installing roof windows is a complicated and expensive home improvement project. Let's address this concern by looking into how a roof window is installed.

Installing a roof window is easier than you think

Complicated installations, accidents, and expensive processes are just some of the typical concerns associated with installing roof windows. But installing roof windows doesn't have to be difficult or time-consuming. Often, it's just a question of knowing the process and choosing the right person for the job.

Understanding the process will give you peace of mind 

Homeowners who've never done any roof-related projects at home often worry about installing roof windows. These concerns can often be addressed by simply understanding the installation process. This will also help you if you're project managing the process.

Looking at the process from a VELUX perspective, it's easier to get it done and less of a hassle than you might think. That said, installing roof windows requires excellent skill.

Key takeaways
  • Installing a roof window is much easier than you think it is, you just need to understand the process.
  • The steps to installing a roof window are straightforward, starting with determining the right spot for a window and ending with closing the hole around the window with plaster. See the full checklist in the article.
  • Getting a professional, especially a VELUX Certified Installer, to install your roof window is the best way to make sure it is done properly.

The 8 steps of a skylight installation  

There are 8 main steps of a roof window installation: 

Step 1: Determine the right spot

Step 2: Remove the roof slates or tiles (if your house has any)

Step 3: Cut out the hole in the roof

Step 4: Measure the opening for the roof window

Step 5: Install the frame (address the insulation and correct installation to avoid leakage, etc.) The installers secure the frame of the new roof window(s) to the installation battens of your roof while also installing the flashing kit and securing the roof slates or tiles around the flashing

Step 6: Install the window sash

Step 7: Align the inside, ensuring that it is fixed and adequately closed off. The internal lining is added to improve insulation and stop any moisture from passing through the opening around the roof window

Step 8: Clean and paint. Plaster work is done to close the internal hole around the roof window

That's all. After this, all you need to do is enjoy the daylight streaming into your house.
