What is a Rooflight?

Rooflights, often known as flat rooflights, are glass units bonded into a frame designed to sit flat or low-pitched roofs (commonly 0-15 degree pitch). Serving as windows for flat surfaces, they are engineered to on an upstand (also called kerbs) to allow proper weathering. This providing a sleek and modern aesthetic.

What is a Skylight?

Skylights, distinct from rooflights, are windows strategically placed on pitched roofs to introduce natural light into elevated spaces like lofts and attics. These roofs are commonly tile, slate or even metal and required to tie into these with a flashing kit to keep the rooflights weathered. Unlike rooflights, skylights designed to sit inline with the roofing.
