Can I put a Velux Window in my Roof?


Natural light is one of the most sought-after features in a home, and a Velux window is an excellent way to bring it into your living space. These skylight windows not only brighten up your home but also provide effective ventilation and can even increase your property’s value.

At Aiden Sheridan Roofing, Cladding & Carpentry, we often receive inquiries about the possibility of installing Velux windows or Rooflights in various roof types. In this blog post, we will explore the factors you need to consider before installing a Velux window or Rooflight in your roof and how our team of expert roofers can help you with this process.


Factors to Consider Before Installing a Velux Window

  1. Roof Structure and Pitch

The structure and pitch of your roof play a crucial role in determining whether you can install a Velux window. Velux windows can be fitted on roofs with pitches between 15 and 90 degrees, which includes most residential roofs. However, some roof structures may require modifications to accommodate a Velux window, so it’s essential to consult with a professional roofing contractor to assess your roof’s suitability.

  1. Planning Permission and Building Regulations

In most cases, installing a Velux window is considered a permitted development and does not require planning permission. However, if your property is in a conservation area or is a listed building, you may need to obtain permission before proceeding with the installation. Additionally, you must comply with building regulations to ensure proper insulation, ventilation, and safety measures are in place.

  1. Velux Window or Rooflight Positioning and Size

Choosing the right position and size for your Velux window is essential to maximize its benefits. Consider factors such as the room’s layout, ceiling height, and your desired level of light and ventilation when making this decision. A professional roofing contractor can provide guidance on the best placement and size for your specific needs.

  1. Budget

The cost of installing a Velux window or Rooflight will vary depending on the size, type, and any additional features you may require. You should also factor in the cost of labor for installation, as well as any structural modifications that may be necessary. It’s important to establish a budget beforehand to ensure you choose a window that suits your needs and financial constraints.
