Lantern Roof / Roof Lantern

A glazed structure that rises above the main flat roof level, typically in a rectangular form with a hipped or ridge top, designed to flood the room below with natural light. Roof lanterns are popular in single-storey kitchen-diner extensions as an alternative to multiple flat roof lights. They are thermally less efficient than insulated roof lights and require careful detail to prevent condensation.
