Domestic roof construction is the framing and roof covering which is found on most detached houses in cold and temperate climates. Such roofs are built with mostly timber, take a number of different shapes, and are covered with a variety of materials.

Pre-manufactured roof trusses come in a wide variety of styles. They are designed by the manufacturer for each specific building.

Timber trusses also are built in a variety of styles using wood or metal joints. Heavy timber rafters typically spaced 240 cm (8 ft) to 370 cm (12 ft) apart are called principal rafters. Principal rafters may be mixed with common rafters or carry common purlins.
