Attics

An attic is the space between the ceiling of the top floor and the roof structure, typically located directly beneath pitched roofs. In many houses the attic is unfinished and used for storage or to house mechanical systems; in others it has been converted into living space, such as a bedroom or study. The term attic is common in American English, while in some regions the term loft is more frequently used.

Attics usually contain roof rafters, ceiling joists and various framing members. Access is often via a pull-down ladder or a fixed staircase. Finishing a converted attic may involve insulating the roof and walls, installing drywall, wiring lighting, and extending heating or cooling. Ventilation, including soffit and ridge vents, is important to control moisture. Dormers, knee walls and, where present, reinforced floor joists influence headroom and structural load.

Attics are used for storage or utility space, but conversions to living areas require compliance with building codes, including fire safety, means of egress, and adequate insulation. Structural considerations include whether existing joists and roof can support a living space, and whether additional insulation or radiant barriers are appropriate.

Insulation and energy efficiency are related to attic design. Proper insulation and ventilation help reduce energy loss and moisture problems. In cold climates, sealing gaps and adding attic insulation minimizes heat loss; in hot climates, attic ventilation reduces heat buildup.

Maintenance and safety require regular inspections for roof leaks, ice dams, condensation, mold, and pests. Homeowners should check insulation levels and ensure adequate ventilation.
