Hip & Ridge Detail
Headwall Detail
Shed Ridge Detail
Hip and ridge applications are handled in the same
manner.
1. Cut “Z” closure to fit between seams and install
in butyl tape.(Use 3 fasteners on 11” panel, 4 on
15”, 5 on 19 1/4”)
2. Seal neoprene strips into “Z” closures (formed
neoprene for ridge; straight neoprene for hip).
3. Snap hip/ridge cap over “Z” closures for it to lock
into place. Pop-rivet one side only to allow for
expansion and contraction.
Notes:
* Trim must be pop-riveted to Z in at least one
location to control thermal movement.
* Unless otherwise specified, all fasteners for trim
components should be spaced at 2’-0” o.c.
* Install splice plates at ridge cap joints. Pop rivet
splice to one end of ridge cap to allow for
expansion and contraction.
Install appropriate underlayment to the edge.
1. In standard headwall situation (without venting),
run underlayment from roof plane up headwall.
Install panels up to headwall.
2. Fasten “Z” closure in bed of sealant at top of
panel. Seal formed neoprene closure into place
in “Z” closure.
3. Install headwall transition over “Z” closure.
4. Apply counterflashing over the headwall trim,
as required.
1. Install metal panel up to the roof peak.
2. Fasten “Z” closure in bed of sealant at top of
panel. Seal formed neoprene closure into place
in “Z” closure.
3. Fasten starter cleat to face of trim boards at
2” below ridge line.
4. Install shed ridge cap trim over “Z” closure
and starter cleat.
