This is why UK Building Regulations require roofs to be ventilated, either by the use of soffit vents, ridge vents, or replacement ventilation slates or tiles. [7] A common method of ventilating a roof is to make openings in the soffit and ridge to allow natural air flow. This example also has ventilated exterior walls called rainscreen ...
A soffit is an exterior architectural feature, generally the horizontal, aloft underside of the roof edge. Its archetypal form, sometimes incorporating or implying the projection of rafters or trusses over the exterior of supporting walls, is the underside of eaves (to connect a supporting wall to projecting edge(s) of the roof ).
Bell-cast (sprocketed, flared): A roof with the shallow slope below the steeper slope at the eaves. Compare with bell roof. East Asian hip-and-gable roof; Mokoshi: A Japanese decorative pent roof; Pavilion roof : A low-pitched roof hipped equally on all sides and centered over a square or regular polygonal floor plan.

Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
Eaves overhang, shown here with a bracket system of modillions. The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong ...
In the greatest extent of the knee wall, this extends to the imaginary intersection of the outer wall with the upper edge of the rafter. The smallest dimension is when the knee wall is understood to mean only the wall that goes beyond the attic ceiling (excluding the base purlin). Between these possibilities, other methods of measurement are in ...
Roof pitch is the steepness of a roof expressed as a ratio of inch(es) rise per horizontal foot (or their metric equivalent), or as the angle in degrees its surface deviates from the horizontal. A flat roof has a pitch of zero in either instance; all other roofs are pitched .
A mansard roof on the Château de Dampierre, by Jules Hardouin-Mansart, great-nephew of François Mansart. A mansard or mansard roof (also called French roof or curb roof) is a multi-sided gambrel-style hip roof characterised by two slopes on each of its sides, with the lower slope at a steeper angle than the upper, and often punctured by dormer windows.
