Many homeowners don’t think much about their roof windows until something goes wrong. If your roof window is over 15-20 years old, there’s a good chance it’s no longer performing as well as it should, even if it still opens and closes.
At Yorkshire Roof Windows, we regularly visit homes across Yorkshire where customers have been putting up with small issues for years, only to discover that a replacement window could make their home warmer, brighter, quieter and more energy efficient.
Here are seven common signs that it may be time to replace your old roof window.
1. You’re Noticing More Condensation Than Usual
A small amount of condensation can be normal, especially during colder months. However, if condensation regularly forms between the panes of glass, this often indicates that the sealed glazing unit has failed.
Once the seal has broken, the insulating properties of the glass are significantly reduced, which can lead to higher energy bills and a less comfortable living space.
2. The Window Feels Draughty
Do you feel a cold breeze around your roof window, even when it’s fully closed?
Older roof windows can develop worn seals, warped frames or gaps that allow heat to escape and cold air to enter. Many homeowners assume this is simply part of living in a loft conversion or attic room, but modern Velux windows provide far better insulation and airtightness.
3. The Frame Is Showing Signs of Rot or Damage
Timber roof windows can suffer from years of exposure to moisture, condensation and changing temperatures.
Signs to look for include:
- Peeling paint
- Soft or spongy wood
- Black staining
- Cracks around the frame
While minor cosmetic issues can sometimes be addressed, extensive timber deterioration often makes replacement the most cost-effective long-term solution.
4. Your Roof Window Is Difficult to Open or Close
Roof windows should operate smoothly and easily.
If your window sticks, jams, won’t stay open or requires excessive force to operate, the mechanism may be worn out. Replacement parts are not always available for older models, making a full replacement the better option in many cases.
5. Water Is Getting In
Even a small leak around a roof window should never be ignored.
Water ingress can lead to:
- Damp patches
- Mould growth
- Damage to plasterwork
- Timber decay
Sometimes the issue can be resolved with repairs, but older windows that are already nearing the end of their lifespan are often better replaced altogether.
6. The Glass Doesn’t Keep the Heat In
Modern Velux windows are far more energy efficient than those installed 15 or 20 years ago.
Advances in glazing technology mean today’s roof windows help keep homes warmer in winter and cooler in summer. Many homeowners are surprised by the difference a replacement window can make to room comfort and heating costs.
7. Your Home Feels Dark Compared to Modern Properties
Older roof windows often have thicker frames and smaller glass areas.
Modern Velux designs allow more natural daylight into your room without increasing the overall window size. This simple upgrade can completely transform a loft conversion, bedroom, home office or attic space.
Is It Worth Replacing an Old Roof Window?
In many cases, yes.
A new roof window can improve:
✔ Energy efficiency
✔ Home comfort
✔ Natural light levels
✔ Ventilation
✔ Property appearance
✔ Long-term reliability
If your existing roof window is showing several of the signs above, replacing it now could save you money on future repairs while improving the enjoyment of your home.
