Hip support trays are fitted above the vent roll to provide a straight and level platform to support the tiles up the hip of the roof.  This is particularly necessary when using profiled or deep flat tiles. The tray is 1200mm long and must overlap the tray below it on the hip by 100mm. The trays can easily be cut to length or shaped to the angles required at the eaves of the hip and ridge-hip junction by using a sharp utility knife. Simply fasten the Hip Support Tray to the previously installed hip battens using suitable stainless steel nails.
