Roof windows are an important element of modern homes. They bring natural light into a living space, transforming any space into a bright haven. But like any element of a home, roof windows do not last forever. For a homeowner who is looking to invest in a roof window, you may be wondering just how long they last for.

So just how long do windows last? And how can you extend their lifespan?

In this article, we’ll explore the factors that influence the lifespan of roof windows. We’ll give you some insights into their usual durability, some tips on how you can invest in a durable roof window, and explain how you can find long-lasting roof windows.

The lifespan of roof windows

The general lifespan of a roof window is not easy to estimate. Popular roof window brand, Velux, suggest that the average lifespan of their products ranges from 20-30 years. This may seem like a long time, but there are many different factors that can cause this lifespan to vary.

Firstly, the materials used within a roof window will determine how long it will last for. Wooden roof windows, for example, will require more maintenance than something built from vinyl or aluminium.

You should also keep in mind that the location of your property is going to affect the lifespan of a roof window. If you live in a place which has extreme weather conditions – especially wind, rainfall or high humidity – there is more of a chance for damage to accumulate, shortening the lifespan of your roof windows.

Remember that exposure to UV rays can affect the performance and appearance of fixed and opening windows over time too. Because of this, it is vital that you carry out regular inspections of your roof windows to catch any signs of deterioration and fix them.

How to make sure your roof windows last

Now that we’ve gone over how long windows can last, let’s take a look at what you can do to extend their lifespan. There are a few main factors to keep in mind before and after purchasing roof windows to make sure they last for the longest time they can.


Firstly, it’s important to choose a roof window that is made from high quality materials. A good way to ensure this box is ticked is to purchase your roof windows from a reputable manufacturer or supplier. These brands will prioritise materials that are resistant to corrosion, fading and more.


One of the factors that will determine the lifespan of your roof windows is how they are installed. You should always opt for professional installation that makes sure the windows are properly sealed. Sealing prevents water leaks and minimises the risk of damage from weather. This will contribute to the overall longevity of your roof windows.


As mentioned above, you will need to regularly check your roof windows to make sure you find any potential hazards or problems before they occur. From these checks you can carry out some simple maintenance. You should address minor problems, clean the glass, and lubricate any moving parts. Doing this regularly will help to safeguard your windows for years to come.
