Abstract: An expansion joint having three axes of expansion for roof to wall and roof to roof applications. An expansion joint with roof to wall applications preferably includes a continuous cleat, a curb rail, a condensate seal, a formed cap, a sliding surface plate and a plurality of retainer plates. The continuous cleat slides vertically relative to a wall and horizontally relative to a roof curb. The continuous cleat slides vertically relative to the formed cap. An expansion joint with roof to roof applications preferably a continuous cleat, a formed cap, a curb rail, a Z-curb rail, a condensate seal and a plurality of retainer plates. The continuous cleat slides vertically relative to a fixed curb wall and horizontally in two axes relative to a free roof curb.

Abstract: A hip ventilator preferably includes a plurality of lower intermittent spacers, a pitched perforated support member, a plurality of upper intermittent spacers, a plurality of hip covers and two hip cover end caps. First and second water dams are attached to a top of the hip roof. The plurality of lower intermittent spacers are then attached to the hip roof over the first and second water dams. The pitched perforated support member is placed on top of the plurality of lower intermittent spacers. The plurality of upper intermittent spacers are attached to the plurality of lower intermittent spacers. The plurality of hip covers are snapped on to the pitched perforated support member. The two hip cover end caps are attached to the roof and two hip covers. A deflector strip is preferably attached adjacent each side of the hip ventilator.
