Bargeboard – The wide board fitted to the end of a gable roof. It’s found just beneath the edge of tiles or slates following the slope of the roof from the eves to the ridge.
Batten – Long strips of soft wood to which roof coverings or plasterboards are attached. However, they can also be used to support roof coverings when fixed to the rafters.
Collar – A horizontal timber tie, which is attached at each end to opposite spars in a pitch roof. Collars can be fixed at any height between the wall plate and half way up the roof.
Covering – Simply the external material laid or fixed onto a roof, which protects the entire building. Materials can include slate, interlocking or plain tiles, corrugated sheets, and zinc.
Eaves – The eaves of a roof is its lowest edge. They may be flush with the outer face of the wall or project out some distance.
UPVC Fascias – Horizontal boards that are attached to the ends of rafter feet. Any guttering will be fixed to the building’s UPVC fascia boards.
Flashings – Narrow pieces of lead that prevent moisture ingress and are positioned at the joining between the vertical faces of walls or framing and pitched roofs, flat roofs, or gutters.
Gable – The triangular upper part of wall at the end of a ridge roof.
Jack rafters – Short spars that run from a hip to the eves or from a ridge to a valley.
Joist – There are two kinds of joist. Floor joists are bearing timbers that form part of a suspended floor to which the floorboards are nailed to and ceiling attached underneath. Ceiling joists are bearing timbers that span an area to which a ceiling is fixed to the underside.
Parapet – A low wall that projects beyond the eves at the roof’s edge.
Purlin – A horizontal timber beam that provides intermediate support to the rafters.
Rafters (Also common rafters) – Similar to joists but inclined from the eaves to the ridge. They also support a pitched roof covering.
Ridge – The highest point of a pitched roof that receives the head of the spars.
Sarking – Boards nailed to the upper edges of spars, where roofing materials are secured.
Soffit – Boards fitted to the underside of overhanging eaves.
Spars – Same as common rafters and similar to joists.
Strut – Intermediate supporting timber for a purlin.
Verge – The edge of a roof that runs from eaves to ridge at a gable.
