Roof space refers to the area located directly beneath the roof of a building. It is often used for various purposes, such as housing insulation, ventilation systems, or even storage. In residential buildings, this space can be accessed through a hatch or staircase, allowing homeowners to utilize it effectively. In many cases, roof space is also known as the attic. This area can play a crucial role in maintaining a building's energy efficiency by helping regulate temperature. Proper insulation in the roof space can reduce heating and cooling costs, making it an important aspect of home design and construction.
