Transform Dark Spaces With Natural Daylight
A Velux roof window is one of the most effective ways to bring natural light into a loft conversion, extension or any room with a pitched roof above. Daylight improves the feel of a space dramatically, makes rooms look larger and reduces dependence on artificial lighting. Modern Velux windows also provide excellent ventilation, noise reduction and thermal performance.
Radiant Roofing supplies and installs the full range of Velux roof windows across Kent, Sussex and Surrey. We handle every aspect of the installation — cutting the structural opening, reinforcing the timbers, fitting the window and flashing kit, integrating with the surrounding tiles or slates and installing the internal lining. The result is a factory-finished look that is fully weathertight from day one.

Frequently Asked Questions
A Velux window installation typically costs between £800 and £3,000 including supply and fitting. A standard centre-pivot window in a straightforward tile roof costs £800 to £1,500. Larger windows, electric models or installations requiring structural reinforcement sit at the higher end. We include the flashing kit, tiling and basic internal lining in all quotes.
Most single Velux installations take one day. The morning is spent cutting the opening and fitting the window, and the afternoon completing the flashing, tiling and internal lining. Multiple windows or complex structural work may take two days.
In most cases, Velux windows fall under permitted development and do not need planning permission. However, there are exceptions for listed buildings, conservation areas and windows that would overlook neighbouring properties. We can advise during our consultation and recommend checking with your local authority if needed.
