Roof windows can transform dull and dark interiors into vibrant, sun-drenched havens. With their striking design and light-transmitting capabilities, roof windows have become a unique addition.
In the UK, various properties have flat roofs incorporated, such as offices, buildings, and residential homes. Flat-roof houses are particularly rising in popularity in seaside towns where excess building height can obstruct your neighbouring views.
To be considered a flat roof skylight, pitches generally can not exceed 10 degrees. Flat roof windows are available in several sizes and are typically used with GRP, Roofing Felt or other dynamic flat roof materials available today.
This blog post delves into roof windows, explicitly focusing on different types of flat roof windows, such as Velux flat roof windows, flat glass roof windows, flat roof domes and roof lanterns.

Flat Roof Domes
A flat roof dome is a type of roof light installed on a flat roof to provide natural daylight and ventilation. Flat roof domes are typically a more cost-effective solution when compared to their flat glass roof light counterparts. As the light transmits through a clear PVC, the thickness is usually referenced by ‘skins’ rather than glazing. The most common skin thickness is double or triple. Flat Roof Domes can be fixed or vented through manual, electrical or solar openings.
Flat roof domes are available in various sizes and shapes, so you can find one perfect for your home.
