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.
