Roofs are basically five types.
Hip roof frame construction.
Stick framing creates a triangle between the rafters and ceiling joists.
Intersecting the intersecting roof consists of a gable and valley or hip and valley.
Gable and hip roofs may be built primarily of trusses.
Other roof shapes particularly those with dormers or on houses with cathedral ceilings attic rooms or attic storage areas are stick built.
Hip rafters are the diagonal rafters that span from the ridge at the top down to the corners of the roof.
Framing a hip roof thus demands expertise in this field so that the completed structure can be designed with more accuracy and safety of the house.
Another common design in the northeast is the saltbox which is a gable roof with one longer side.
Building a hip roof requires proper attention towards some major factors such as measurements framing and rafter adjustment.
The valley is formed where the two.
The main structural parts of a roof are ceiling joists ridge board jack rafter hip rafter common rafters creeper rafters raking plates out riggers and noggings or last rafter overhang.
Roof framing is one of those carpenter skills that appears quite complicated and indeed some roof designs are difficult.
If the wall plates are all square of equal lengths then the hipped rafters would form a pyramid shape like the picture above normally a roof is rectangle and there are more yellow common rafters.
A collar beam adds strength to the triangle at the middle.
Tie down fixings tie down fixings are used to resist uplift and shear forces lateral loads in floor framing wall framing and roof framing.
The first step in the process of erecting the hip roof is to get the ridge beam into place at the top of the roof.
A disadvantage of the hip roof is that it is more difficult to construct than a gable roof.
If the extension length is half the extension length the 2 hips will meet at the existing wall and the roof will come to a peak with no ridge like half a pyramid.
These hip rafters run at a 45 angle from each corner of the building to the ridge.
A hip roof or a hipped roof is a style of roofing that slopes downwards from all sides to the walls and hence has no vertical sides.
The roof extension length must be at least twice as long as its width or the 2 hips will meet before they reach the existing building wall.
It is the strongest type of roof because it is braced by four hip rafters.
Hip the hip roof has four sloping sides.
Shed gable hip gambrel and mansard.
Attach 4 6 centering rafters and lift the ridge beam into place.
This style of roofing became popular in the united states during the 18 th century in the early georgian period.
