Introduction
Thinking about bringing more natural light into your loft or top-floor rooms? Velux windows are a brilliant solution, offering elegant design, practical ventilation, and a transformative effect on dark or enclosed spaces. But if your home wasn’t originally built with roof windows, can they be added later?
At Lutterworth Roofing Repairs, we often get this question from homeowners in Lutterworth, Leicestershire — and the short answer is yes. Retrofitting Velux windows into an existing roof is not only possible, it’s a smart investment in comfort, energy efficiency, and property value. In this post, we’ll explain how it works, what to consider, and why professional installation is essential.
Key Takeaways
- Velux windows can be installed in most existing pitched roofs.
- Professional planning and fitting ensures a watertight and efficient result.
- Placement, structure, and roofing material affect the approach taken.
- Benefits include increased daylight, ventilation, and home value.
Yes — Velux Can Be Retrofitted to Existing Roofs
Whether your home has tile or slate roofing, Velux windows are designed with flexibility in mind. Most existing pitched roofs — typically between 15° and 90° — are suitable for installation, even if they were built decades ago.
Common applications include:
- Loft spaces
- Stairwells and hallways
- En-suite bathrooms and attics
- Converted or unconverted roof voids
The key is a structural assessment to determine the ideal location and ensure the rafters can be adapted safely.
Key Considerations Before Installation
Structural Adjustments
While Velux windows are designed to fit between standard rafters, your existing roof may need some adjustment — such as trimming or reinforcing surrounding timbers.
Orientation and Light Direction
South-facing windows will flood your room with sunlight, while north-facing ones offer consistent but softer light. The orientation affects heat gain, brightness, and ambience — something to bear in mind during planning.
Room Function and Finish
Adding a Velux to a bedroom or bathroom? You may need additional considerations such as blackout blinds or moisture-resistant finishing around the window.
Planning Requirements
Most Velux installations fall under permitted development, but certain properties (especially in conservation areas or with listed status) may require consent. It’s worth checking before work begins.
Benefits of Adding Velux to an Existing Roof
There’s more to Velux than just more daylight. Fitting one or more roof windows can offer a range of practical and aesthetic advantages.
Why homeowners love the upgrade:
- Brightens previously dark, unused areas
- Adds character and architectural interest
- Increases ventilation and airflow
- Enhances energy efficiency with natural light
- Adds value to the property — particularly in loft conversions
For homeowners in Lutterworth, it’s a smart move that enhances day-to-day living and long-term property value.
Why You Need a Professional Installer
While Velux windows are built with precision and quality in mind, their performance depends entirely on correct installation. Poor fitting can lead to leaks, draughts, or long-term roofing damage.
At Lutterworth Roofing Repairs, we offer:
- Careful assessment of roof structure and layout
- Expert removal and reinstatement of roof coverings
- Accurate fitting with full flashing kits and weather sealing
- Internal finishing for a clean, polished result
We ensure the window works as intended — and looks like it’s always been part of your home.
