When to Upgrade Your Rooflights for a Warmer, Brighter & More Efficient Home

If your rooflights are more than 20 years old, they may be costing you more than you think. Older models often let heat escape, create draughts and don’t deliver the daylight or comfort that today’s overhead glazing can provide. Replacing and upgrading these glazed features will help keep precious warmth inside during winter, ensuring a more energy-efficient home all year round, while boosting its style and value.

Improving your home’s energy efficiency

Modern roof windows offer significantly better thermal performance than those over a decade old. Today’s triple-glazed units are twice as efficient for thermal performance compared to the double-glazed versions of more than a decade ago – plus, units 20+ years old may not deliver the same performance now as they did when they were first installed.

Therefore, for homeowners replacing older single-glazing, upgrading to brand-new modern units, such as the range of roof windows from VELUX, could help save significantly on energy bills. Over time, those savings really add up – making replacement not just a design upgrade but a smart financial move.

When is the best time to upgrade your rooflights?

Cold weather, condensation and increased heating demand make winter the time when quality glazing is most needed and recognised. This means that autumn is the perfect time to get your home ready and upgrade old rooflights, ensuring a warmer, draught-free home right through the colder months.

The year-round benefits

While autumn is the key time to think about replacements, investing in new rooflights is a smart choice any time of year. In spring and summer, pairing them with solar shading features, such as VELUX blinds and shutters, gives you better control over light, reduces glare and helps keep interiors cool. Seasonal styling options mean you can create a comfortable, beautiful space whatever the weather.

Improving indoor comfort

Upgrading your roof windows can do more than lower your home’s heating bills. Modern glazing enhances sound insulation, helping to create a quieter, calmer home, while extra daylight can boost wellbeing and daily rhythms, especially during the darker months. From home offices to children’s bedrooms, every space will be more enjoyable to spend time in.

Adding value & futureproofing

In a recent study conducted by VELUX, 46% of homeowners said that futureproofing was a top priority when renovating. Replacing your roof windows is a visible upgrade that improves both the look and the market value of your home. It’s often timed alongside other projects such as re-roofing, upgrading insulation, or converting a loft room, making replacement an ideal long-term investment.
