Hip and Ridge Caps

• Apply double sided Hip & Ridge Seal

❶

centered over the

point where the shingles come together.

• Install Tapered Hip Caps or 12” Ridge Caps over Hip & Ridge

Seal. Tapered Hip Caps fasten with Clips

❷

. Please note:

METALWORKS 12” Ridge Caps with a built-in nailing hem do
not require clips.

• Face-fasten the first and last cap of each section. Fasten

through the cap on all four corners using nails or screws.
Apply sealant over exposed fasteners.

• At the junction of two Valley Flashings, install 12” Ridge Caps

to hide the sealed joint.

• Alternate method for extreme wind areas: Tapered Hip Caps

may be face-fastened. Fasten through the cap on all four
corners using nails or screws. If using nails, apply sealant
over exposed fasteners.

• In ridge vent application, install the ridge vent over the

shingles apply double sided Hip & Ridge Seal to the ridge
vent then install 12” Ridge Caps over the vent

❸

Depending on the type of vent used, Hip & Ridge Seal may
not be applicable.

• 12” Ridge Caps can be used on the Hip or Ridge. Hip Caps

should be used only on the Hip of the roof.
Note: Ensure that fasteners penetrate the roof deck min. 1/2”.

Headwall Detail

• When working around dormers, apply TAMKO’s TW Moisture

Wrap tape, with a minimum width of 6 inches, to the
headwall area first and then to the sidewalls, wrapping the
lower end back on top of the headwall. Apply sealant on top of
the TW Moisture Wrap at the two front corners of the dormer.

• Cut shingles to fit below the

dormer and fasten through the
top of the shingle

❶

. Along the

bottom corner of the dormer, cut
the top lock of the shingle so
that the sidewall flashing will lie
flat over the shingle

❷

• Headwall Flashing should be

formed from METALWORKS
Trim Coil

❸

. The flashing strip

should be bent to extend a
minimum of 3-1/2 inches up the
vertical wall and overlap the
last course of shingles by a minimum of 3-1/2 inches

❹

Pipe/Vent Detail

• Cut the shingle(s) to fit tightly around the pipe/vent, apply one-

part urethane contractor-grade sealant around penetration

❶.

• Cut and fold back the top lock of the shingle that the pipe or

vent flashing will cover

❷

• Apply sealant to the

underside of the flashing

❸

Install so that the next full
shingle will lap over the
flashing. Apply sealant at
the bottom of the shingle
where it meets the top of
the pipe/vent

❹

. Apply

sealant over exposed
fasteners

❺

• When coming out of a valley, vary the shingle length to ensure

staggered appearance. Cut the shingles to fit to the valley
angle

❹. The first shingle is a full length shingle. The

remaining shingles and courses coming out of the valley are
cut so the shingle side locks are staggered up the roof. As each
course is calculated, remember to take into account the amount
of shingle that is hidden in the receiver on the Valley Flashing.

• For the first course of shingles into or out of a valley, cut a

6-inch notch in the return of the bottom locking lip of the first
shingle only

❺. In all remaining valley shingles, cut a 1/2 inch

V-shape notch in the return of the bottom locking lip
approximately 6 inches from the center of the valley for
drainage.

❻

• At ridges and hips, line the cut edge of shingles up against

one another and fasten through shingles with at least two
fasteners per shingle.
