What are the benefits of replacing roof windows: Key takeaways

Many people wonder whether roof window upgrades are worth it. The short answer is yes. When you replace old and outdated roof windows with the latest VELUX roof windows you make your home brighter and more welcoming, which should increase its value.   You also improve your home’s natural ventilation and insulation, which makes your home more comfortable, all year round. For the longer answer, read on.

New roof windows bring more light into this loft bedroom

New roof windows increase the flow of natural light into your home

New VELUX roof windows have larger glazing areas compared to older models. So, even if you replace a roof window of exactly the same size - with a new roof window, you’ll be bringing more daylight in. 

To ensure adequate day light levels, it’s recommended that any room should have a glazed area that is at least 20% of its floor area. Roof windows allow maximum daylight to enter your home and provide up to twice as much light through a window as a façade window of the same size. So, if your room needs a brightness boost, consider replacing older roof windows. 

The latest VELUX roof windows will transform your space by flooding it with natural light. When you bring more natural light into your home it lifts your mood and increases your connection with the natural world outside. 

Replacement roof windows improve home insulation

A well-insulated home will feel warmer in the colder months and cooler in the hotter months. If you have old or outdated roof windows, you may be able to feel draughts around the frame from where air can escape. The latest VELUX roof windows are designed to keep your home comfortable and draught-free, featuring double-glazing as standard. 

If the time is right for replacing your roof windows, consider triple-glazing. Not only will you benefit from added warmth, you’ll also notice significantly diminished outside noise. Perfect for homes near busy roads or flightpaths. 

Does updating roof windows increase home value?

Replacing roof windows can increase the value of your property. When you sell your home, you need to obtain an energy performance certificate (EPC), which will classify your home from A for the most efficient to G for the least efficient. 

Having the latest roof windows installed will help to increase your energy efficiency rating, make energy savings and make your home more attractive to potential buyers, which can increase your property’s value.

Replacement roof windows can help towards energy savings

By increasing the flow of natural light into your home and improving its insulation, the latest VELUX roof windows will make your home brighter throughout the year, warmer in winter, and cooler in summer. All of this helps to reduce your reliance on artificial light and heating systems, which helps to bring your bills down and shrink your carbon footprint.

Turn your home into a model of energy efficiency

Get the most out of your home improvement project with a roof window upgrade

It’s time to replace your roof window if you notice your window is leaking when it rains, if the glass is no longer clear or broken, or if you can feel draughts around the frame. If you’re renovating or replacing your roof it’s often worth upgrading your roof windows at the same time.

Enjoy more daylight and less upkeep, with a VELUX white maintenance-free finish. Couple this with solar operation for the ultimate home upgrade.

Bring in more light with the latest VELUX roof windows

The frames of the latest VELUX roof windows are much slimmer than older roof windows of the same size, so you will instantly find your room feels brighter after the switch. While you are replacing your old roof windows, you can consider increasing your roof window size. Or to really make an impact on how your home feels, now could be the perfect opportunity to add additional roof windows, to bring even more light into your home. 

Upgrade from manual to automated roof windows

If your roof windows are out-of-reach or you’d like the added convenience of home automation, explore solar or electric roof windows. The switch from a manual to solar roof window is straightforward as there’s no extra wiring required. A simple home upgrade which could greatly improve your indoor comfort and connection to the outdoors. 

Harness the power of solar to reap more benefits from your roof window upgrade

You can automate your VELUX roof windows and accessories without having to wire them up to your electricity supply with VELUX solar roof windows. With a built-in rain sensor, solar roof windows can be opened and shut from anywhere in your home, or via App Control, and will automatically close when it starts to rains. They are a simple and effective way of airing out your home with free energy from the sun. What’s more, they even work on cloudy days. 

Refresh your home with bright, white interior finishes

When replacing old pine VELUX roof windows, we recommend a white maintenance-free finish. It’s our most robust and durable option that - as the name suggests - is completely maintenance free. Particularly suited to humid rooms, such as kitchens and bathrooms, it is moisture-resistant and easy clean. Enjoy decades of outstanding quality with no need for sanding or repainting. 

If you prefer a more traditional look and feel to the interior of your home, the white painted finish is a timeless option. 

A roof window replacement is quick and easy

A roof window of the same size can be replaced in just four hours. The works can usually be completed from inside your home with no need for expensive scaffolding. If you opt for a larger roof window or decide to add further roof windows this can be done in a couple of days. It’s all done with very little mess or damage to your interior.
