Pitched roof
Encyclopedia
A pitched roof is a roof for which one or more roof surfaces is pitched more than 10 degrees, and alternately a roof with two slopes that meet at a central ridge. Some definitions are even more general, including any roof with a sloping surface or surfaces.
The term roof pitch
(in roof construction) refers to the angle of a roof from the horizontal. The word pitch can also be used as a verb, i.e old roof framers refer to having to "pitch a roof."
A variant of the pitched roof is the lean-to roof, a roof structure where the roof leans to one side of the house. Rafters are connected to the highest wall which are declined to a lower wall.
The rafters are often connected into the wall individually or even supported on a wall plate bedded within the wall. This type of roof can have no joist
at all or have a tie or have a joist with a strut
to give more strength.

Joist
A joist, in architecture and engineering, is one of the horizontal supporting members that run from wall to wall, wall to beam, or beam to beam to support a ceiling, roof, or floor. It may be made of wood, steel, or concrete. Typically, a beam is bigger than, and is thus distinguished from, a joist...

Strut
A strut is a structural component designed to resist longitudinal compression. Struts provide outwards-facing support in their lengthwise direction, which can be used to keep two other components separate, performing the opposite function of a tie...
