Velux & Skylight Installation in Northern Ireland

Roof windows are one of the simplest ways to transform a dark room. RoofersNI connects homeowners across Northern Ireland with fully insured local roofers who fit, replace and repair Velux windows, skylights and roof lanterns.

Northern Ireland has plenty of grey days, so making the most of natural light really matters. A roof window lets in far more light than a vertical window of the same size, and it adds ventilation too. They are ideal for loft conversions, landings, bathrooms and kitchen extensions, and can add value to your home.

Most Velux windows can be fitted from inside the loft in a day, often without scaffolding. The roofer cuts an opening, trims the rafters, fits the frame and a matching flashing kit, then makes good the slates or tiles around it. Internal plastering and lining finish the job.

For flat roofs on extensions, options include flat glass rooflights, domed skylights and roof lanterns. They need to be installed with the right upstand and sealed properly into the roof covering to stay watertight.

In most cases roof windows fall under permitted development and do not need planning permission, as long as they do not project too far from the roof slope. Listed buildings and homes in conservation areas may need consent, and building control applies to loft conversions.

In Belfast, roof windows are popular for loft bedrooms in terraces and semis. In Lisburn, many families add them to new loft conversions and extensions. Send us a WhatsApp with your area and what you have in mind.
