Velux Installation Questions Answered
Technical guidance on roof windows and installation process.
Velux windows are designed specifically for pitched roofs (typically 15-90 degree pitch) and open like traditional windows — either by pivoting on a central axis or by top-hung operation. This provides better ventilation angles than fixed skylights. Standard skylights typically refer to fixed or vented units suitable for flat roofs. Velux systems include purpose-designed flashing kits, insulation collars, and interior linings that integrate with standard roof construction.
Velux offers extended guarantees (up to 20 years on glass, 10 years on products) but only when installation is carried out by certified installers using genuine Velux flashing kits. Non-certified installation or generic flashings void the guarantee. Our certification means we understand Velux specification requirements, install flashings correctly for every roof covering, and can register your guarantee directly.
Window quantity depends on room size, ceiling height, and desired light levels. As a rough guide, a standard 15m2 bedroom needs approximately 2-3 standard-sized windows (78x118cm) or equivalent combinations. South-facing rooms need less glazing than north-facing spaces. We use daylight factor calculations during survey to specify optimal window numbers and sizes.
Velux requires rafters or truss structures with adequate load capacity (typically 50kg/m2 per window) and appropriate pitch range. Trussed roofs require structural strengthening between trusses. We assess your roof structure during survey and specify any necessary timber work or structural calculations. Conservation rooflights are available for listed buildings or conservation areas.
Most Velux installations fall within permitted development rights, particularly on rear roof slopes. Front-facing installations and those in conservation areas or on listed buildings may require planning permission. Article 4 directions in certain London boroughs add restrictions. We advise on consent requirements during survey and handle any applications required.
We offer complete interior finishing packages: plasterboard linings, Velux internal blinds, and painted reveals. External options include conservation rooflights with recessed glazing for period properties, or standard installations with visible flashing. We can coordinate with interior designers and decorators for a complete finish.
