Getting the wall plates or top plates as they are sometimes called right is important because all the ceiling joists, roof rafters hips etc. will all be fixed to them. In order for all the roof components to work, they must be square, parallel, level and fixed down properly. In this video we see the build progressing to brickwork and blockwork up to wall plate. We have to deal wasp nest removal from the roof space in our two stor. 2 Rafters vs. Trusses A key decision when framing a roof is whether the design will use rafters or trusses. Rafters and trusses are both structural components that frame the roof. Rafters are framing boards that extend from the ridge to the wall plate and are usually built on site. Pitch is the slope or angle from the wall plate to the roof ridge line. Pitch can vary a great deal, from a shallow slope up to a very steep pitch. Pitch for a gable roof, the most common, is generally 1/4 or 1/3; which is equal to 1/4 or 1/3 the total span of the building, not counting any overhang.

Timber framing A plate in timber framing is "A piece of Timber upon which some considerable weight is framed.Hence Ground-Plate.Window-plate [obsolete]." Rafters are beams that run from the peak of the roof to the top plate of the supporting walls. They join at the peak of the roof by connecting to the opposing rafter or to a ridge beam that runs the length of the peak of the house or shed. Rafters are installed piece-by-piece during the construction of the roof.

Two types of wall plates are logically named the top plate and the bottom plate (sometimes called "sole plate"). The top plate can be a single board (single top plate) or doubled up (double top plate). Double top plates are most common on exterior or interior load-bearing walls. Definition of Cripple Jack Rafter or Valley Jack Rafter a rafter running at right angles (90°) from the ridge of a roof down to the valley below. Cripple jack rafters or valley jack rafters never make it to a wall top plate - instead they intersect a valley formed by another roof.
Rafters are loading bearing structural members that are used in roof construction. They typically run from the ridge board or hip of the roof at a sloping angle to the roof wall plate, columns, or roof beams, depending on the support system adopted for the entire roof structure. Wall Plate. 1.) A horizontal member, usually timber, bolted or otherwise fixed to the top of a wall to which the roof framing is fixed. 2.) A horizontal member, such as a steel plate fixed to a masonry or concrete wall to carry the end of a beam or to attach a beam to other members. 3.)
