10. HIP AND RIDGE FASTENING DETAIL
TAMKO recommends the use of TAMKO
®
Hip and Ridge shingle products.
Where matching colors are available, it is acceptable to use TAMKO
®
Elite
Glass-Seal
®
shingles cut down to 12" pieces.
IMPORTANT: PRIOR TO INSTALLATION, CARE NEEDS TO BE TAKEN TO
PREVENT DAMAGE WHICH CAN OCCUR WHILE BENDING SHINGLES IN
COLD WEATHER.
Apply shingles up to a hip or ridge from both sides of the roof before finishing
the intersection. To facilitate finishing, adjust the last few courses so that
the ridge capping will adequately cover the top courses of shingles equally
on both sides of the ridge.
To apply the capping, bend each shingle along the centerline so that it will
extend an equal distance on each side of the hip or ridge. Chalk lines may
assist in proper alignment. In cold weather, warm the shingle until it is
pliable before bending.
Apply the shingles with a 5-1/8" exposure, beginning at the bottom of the hip
or from the end of the ridge opposite the direction of the prevailing winds.
See Figure 1. Secure each shingle as illustrated in Figure 2 with one fastener
on each side, 5-5/8" back from the exposed end and 1" up the from the
edge. DO NOT NAIL BELOW THIS LINE 1" UP FROM THE EDGE. The length
of the fastener should be long enough to penetrate through the roofing
material and 3/4" into the wood decking or completely through the decking.
In high wind areas, it may be advisable, at the discretion of the roofing
contractor, to use a spot of sealant to minimize blow off problems.
Alternatively, a 2-layer application of TAMKO
®
hip and ridge shingles with
dimension 12-1/4" × 12" may be applied to all Heritage
®
roofs to enhance
the overall appearance. When the second layer is applied, offset this layer
by 1/4" to create a "shadow" effect. See Figure 3.
For a high profile appearance, TAMKO recommends Heritage
®
Designer Ridge. The application instructions are available at
tamko.com or by calling TAMKO's Technical Services Department at
800-641-4691.

Underlayment
9. VALLEY APPLICATION
Center a minimum 36" wide sheet of TAMKO
®
Moisture Guard
®
, TW Metal
and Tile Underlayment, any self-adhesive underlayment designed for use
with asphalt shingles which meets ASTM D1970, or a minimum 50 lb. roll
roofing in the valley. Nail the underlayment only where necessary to hold it
in place and then only nail the outside edges. Install shingle underlayment
and extend over valley flashing by 6".
IMPORTANT: PRIOR TO INSTALLATION, WARM SHINGLES TO PREVENT
DAMAGE WHICH CAN OCCUR WHILE BENDING SHINGLES TO FORM
VALLEY.
• The first course and only the first course of shingles from the
intersecting roof surface should be woven with the first course
of shingles on the starting roof.
• Apply the first course of shingles along the eaves on one of the
intersecting roof planes and across the valley.
Note: For proper flow of water over the trimmed shingle, always
start applying the shingles on the roof plane that has the lower
slope or less height.
• Extend the end shingle at least 12" onto the adjoining roof.
Apply succeeding courses in the same manner, extending
them across the valley and onto the adjoining roof.
• Press the shingles tightly into the valley.
• Use normal shingle fastening methods.
Note: No fastener should be within 6" of the valley
centerline, and two fasteners should be placed at the
end of each shingle crossing the valley.
• To the adjoining roof plane, apply one row of shingles vertically
facing the valley and 2" back from the valley centerline.
Note: For a neater installation, snap a chalkline over the
shingles for guidance.
• To complete the valley, apply shingles on the adjoining roof
plane by positioning the tip of the first shingle of each row at
the 2" point from the centerline where the edge of the vertical
shingle has been applied, covering the vertical shingle.
For alternate valley application methods, please contact TAMKO's Technical
Services Department at 800-641-4691.
