A clip (61) for holding together an upper roof cladding sheet (29a) and a lower roof cladding sheet (29b) in an end to end, i.e. end lap, relationship on a roof. The clip is formed to fit over and lock onto a rib (31) of the lower cladding sheet and to retain the upper sheet on the clip. An elongate weather strip (57) is formed from a compressible material and includes a pan section (81) that can fill a gap between overlapping pans of the cladding sheets. The pan section includes an upper surface having a series of troughs (87) and ridges (89) along the length of the pan section that has the result of providing the pan section with a variable height along the length of the pan section. The ridges of the pan section compress when the upper roof cladding sheet is positioned on and engaged with the lower cladding sheet in an overlapping relationship with the pan section filling the gap between the cladding sheets.
A clip for holding together an upper roof cladding sheet and a lower roof cladding sheet in an end lap relationship on a roof with the upper sheet overlapping the lower cladding sheet, and with the clip being formed (a) to fit over and lock onto a rib of the lower cladding sheet and (b) to retain the upper cladding sheet on the clip.

An elongate weather strip for a space between an upper roof cladding sheet and a lower roof cladding sheet in an end lap relationship on a roof, the weather strip being formed from a compressible material and including a pan section that in use is positioned in and fills a gap between overlapping pans of the cladding sheets, with the pan section including an upper surface having a series of troughs and ridges along the length of the pan section that has the result of providing the pan section with a variable height along the length of the pan section, whereby in use the ridges of the pan section compress when the upper cladding sheet is positioned on and engaged with the lower cladding sheet in an overlapping relationship with the pan section of the weather strip filling the gap between the overlapping pans of the cladding sheets.

An elongate weather strip for at least partially filling a space between an upper roof cladding sheet and a lower roof cladding sheet in an end lap relationship on a roof, the weather strip being formed from a compressible material and including a rib section that in use is positioned in a gap between overlapping pairs of ribs of the cladding sheets, the rib section being formed to only partially fill the gap between overlapping pairs of ribs of the cladding sheets so that air can flow through the remaining part of the gap from one side to the other side of the weather strip.

A stand alone clip for holding together an upper roof cladding sheet and a lower roof cladding sheet in an end lap relationship on a roof with the upper sheet overlapping the lower cladding sheet, and with the clip being formed to fit over and lock onto a rib of the lower cladding sheet and to retain the upper cladding sheet on the clip, with the clip consisting of a top wall and a pair of legs that extend downwardly from opposite sides of the top wall, the top wall including a formation for contacting an upper section of the rib of the lower cladding sheet to space the top wall above the rib, and with the legs including re-entrant portions that are formed to extend into inwardly formed channels defined by re-entrant portions of the rib of the lower cladding sheet, and the leg re-entrant portions and the top wall formation being formed to contact the rib and cooperate together to lock the clip onto the rib when the clip is fitted over the rib, and with the clip further consisting of a pair of opposed outwardly extending formations, such as tabs, for engaging opposed re-entrant sections of a rib of the upper cladding sheet to retain the upper sheet on the clip with the upper cladding sheet being locked onto the clip when the rib of the upper cladding sheet is positioned on the clip.
A stand alone elongate weather strip for a space between an upper roof cladding sheet and a lower roof cladding sheet in an end lap relationship on a roof, the weather strip being formed from a compressible material, the weather strip consisting of a pan section that in use is positioned in and fills a gap between overlapping pans of the cladding sheets, with the pan section including an upper surface having a series of troughs and ridges along the length of the pan section that has the result of providing the pan section with a variable height along the length of the pan section, whereby in use the ridges of the pan section compress when the upper cladding sheet is positioned on and engaged with the lower cladding sheet in an overlapping relationship with the pan section filling the gap between the overlapping pans of the cladding sheets, and with the pan section having a lower surface that has the same profile as the transverse profile of the pan of the lower roof cladding sheet, and the weather strip further consisting of a rib section that in use is positioned in a gap between overlapping pairs of ribs of the cladding sheets.
