When Should You Replace a VELUX Window?
VELUX windows are designed to last for many years, but like all home fixtures, they do eventually wear out, even with proper maintenance. Any visible signs of wear and tear, such as condensation or leaks, are usually the first thing to indicate the need for a replacement roof window. These symptoms typically suggest that the window’s insulation and glazing have degraded, leading to reduced energy efficiency and air quality.
On average, VELUX roof windows can last between 20 and 30 years. If your old roof window is approaching this age, it may be a good idea to consider replacing it, even if there are no immediate issues. Newer models offer vastly improved glazing, better opening mechanisms, and added options like VELUX blinds or smart home integration, making your house more comfortable and energy efficient.
Everything You Need to Know About Replacing VELUX Windows
Replacing old roof windows requires careful planning and preparation to ensure a smooth and quick installation. First, you need to buy the right VELUX roof window for your needs, along with a suitable flashing kit. Once that’s done, make sure to gather all the necessary tools, clear the space, and find someone to help you—removing and installing a roof window is a job for two people. It’s also a good idea to get familiar with the instruction manual beforehand to avoid costly mistakes during the installation.
Below, we’ll explain the entire process step by step to help you complete your VELUX window replacement project successfully. Of course, if you don’t feel confident in your DIY abilities, you can always hire a professional contractor to handle the installation for you.

- Install the new window frame: Make sure it’s positioned correctly and level. Secure it in place using the screws and brackets provided with the roof window.

What Are the Benefits of New VELUX Windows?
New VELUX roof windows offer significantly more benefits than older models. Installing a replacement can dramatically increase energy efficiency, as advanced glazing and seals are far more effective when it comes to preventing heat loss. This, in turn, can help you save money in the long run due to reduced energy and heating costs.
Additionally, replacing VELUX windows can increase the value of your home if you decide to sell. Roof windows are a sought-after feature because of their ability to transform dark lofts into airy living spaces filled with natural light. Not only that, but they also serve as a great source of ventilation—improved air quality helps reduce mould, dust mites, and allergens, creating a more comfortable and healthier home.

Replacement VELUX Windows: FAQ
How Much Does It Cost to Replace a VELUX Roof Window?
The cost of replacing a VELUX window, including materials and labour, starts at around £900, but can be significantly higher, depending on the window size, type of glazing and the complexity of the installation.
Can I Replace My Old VELUX Window Myself?
In most cases, a competent DIYer can replace a roof window without professional help. This, however, doesn’t mean that you should attempt to accomplish this job on your own—you need at least one helper to secure your new window in place. If you don’t have the right tools or experience to do it right, it’s best to call in professionals, as improper installation can lead to damage and leaks.
What VELUX Flashing Do I Need?
Choosing the correct VELUX flashing is crucial for seamlessly integrating your window with the roof tiles and preventing leaks. Pick the same brand and size as your roof window, and make sure it’s suitable for your roof’s pitch and material.
Does a Replacement Roof Window Need to Be the Same Size as the Old One?
Opting for a replacement window of the same size as the old one can make installation significantly easier and quicker, as it minimises the amount of work required. On the other hand, upgrading to a larger window is a good opportunity to bring more light into your home. However, before deciding to install a smaller or larger window, it is important to check whether the roof structure can be altered—it’s best to consult a professional.
