PRESIDENTIAL SHAKE AND
PRESIDENTIAL SHAKE TL SHINGLES
▼
Presidential Shake and Presidential Shake TL shingles are a
premium oversized (141®4" x 40") roofing product. These shingles
would fall in the best category when offering a choice of good,
better and best products.
Figure 15-1: Presidential Shake Shingle.
Presidential has the depth and dimension of hand-split cedar shakes.
Constructed with two laminated layers and an exclusive, patented
sculpted tab. Also, two different colors can be combined to create a
one-of-a-kind look. Using our Special Effects color combinations
provides dozens of options to custom design a roof.
The incomparable Presidential TL is a super-heavyweight shingle (480
lbs./square). Constructed using Tri-Laminate technology, the Presidential
TL is made of two base layers and a top layer of premium materials.
Presidential Shake is available in an impact resistant design;
specially manufactured with a reinforced fiberglass scrim to meet UL
2218 Class 4 impact resistance rating. NOTE: This product must be
installed over a clean deck (no roof-overs) and Presidential impact
resistant starter shingles as well as hip and ridge cap accessories must
be used to obtain the UL 2218 rating.
Figure 15-2: Presidential TL Tri-Laminate Construction.
Fastening, low slope underlayment and flashing requirements, are
special because of the thickness, design and weight of the products.
Open valleys are recommended; however, closed-cut valleys are
also acceptable. Woven valleys are not recommended when applying
Presidential and Presidential TL because the laminated shingle can
buckle and become damaged when shaped into the valley.
On lower-sloped roofs where water drains slowly and due to the
Presidential TL tri-laminate design, step flashing details are important to
ensure a water-tight roof. Extra precautions such as putting a slaters-
edge on step flashings under the shingle or applying two beads of asphalt
cement lengthwise along the top of the step shingle (perpendicular to the
shingle) should be considered when there are multiple roof penetrations
or vertical obstructions in close proximity to each other (ex. several
skylights on the same roof plane or a skylight close to a vertical wall).

1" (25 mm) thick wood deck.
FOR UL FIRE RATING, underlayment may be required.
Apply flat and unwrinkled.
STANDARD OR STEEP SLOPES: CertainTeed recommends
DiamondDeck® Synthetic Underlayment, Roofers Select® High
Performance Underlayment, or shingle underlayment meeting ASTM
D226, D4869 or D6757. Always ensure sufficient deck ventilation, and
take particular care when DiamondDeck or other synthetic underlay-
ment is installed. Follow manufacturers application instructions.
LOW SLOPE UNDERLAYMENT: One layer of WinterGuard®
or its equivalent MUST BE APPLIED OVER THE ENTIRE ROOF.
One layer of Roofers Select or a product meeting ASTM D4869
applied over the REQUIRED WinterGuard is also recommended.
IMPORTANT: Applying two layers of felt shingle underlayment
IS NOT an acceptable alternative to WinterGuard when installing
Presidential TL; however, it IS acceptable for Presidential.
COLD WEATHER CLIMATES (ALL SLOPES): Application of
WinterGuard or its equivalent is strongly recommended whenever
there is a possibility of ice build-up. Follow manufacturers
application instructions.
SEALING: Shingle sealing may be slowed if the shingles are applied
in cool weather and may be further delayed by airborne dust
accumulation. We recommend hand-sealing when weather conditions
are likely to prevent the factory-applied sealant from activating.
CAUTION: To prevent cracking, shingles must be warm enough
to allow proper forming for hips, ridges and valleys.
FLASHING: Corrosion-resistant flashing must be used to help
prevent leaks where a roof meets a wall, another roof, a chimney
or other objects that penetrate a roof.
WARRANTY: These shingles are warranted against manufacturing
defects and are covered by SureStart protection. See the warranty
itself for specific details and limitations.

ALIGNMENT AND SHIPLAP NOTCHES
To maintain the correct 5" and 15" diagonal offset pattern, use the
Alignment Notches at 51®2" and 151®2" from the right edge of the
shingle. These notches are pre-cut into the top of each shingle and serve
as a shingle placement guide for the shingles being installed in the course
above them.

Figure 15-8: Use the alignment notches to ensure shingles
are applied at a 5" and 15" diagonal offset.
Shiplap Notches on the left and right side of each shingle are
used to ensure the proper 4" exposure is continued across shingle
courses by lining up the shiplap notches of adjacent shingles.
▲
ONE CLEAN DECK
APPLICATION METHOD
▼
NOTE: Shingle applications are on 5" and 15" offsets with a 4"
exposure. Apply shingles up the left side of the roof to establish the
pattern and fill in to the right. When cutting shingles, always apply
the right hand portion (cut-off the left side.) Use the pieces cut off
the left rake, hip, or valley to complete courses at the right rake.
PREPARING THE DECK:
◆ Apply underlayment as required. CertainTeed suggests that a
layer of shingle underlayment be applied. For UL fire rating,
underlayment is generally required. Apply flat and unwrinkled.
◆ Snap horizontal and vertical chalklines to assure shingles will be
correctly aligned. Expose all shingles 4" (125 mm).
PRESIDENTIAL STARTER:
Use TWO (2) OVERLAPPING LAYERS of CertainTeeds
Presidential Starter shingles, applied in the following fashion,
starting at left rake/eaves corner. Starting at the right rake/eaves
corner is not permitted. The staggered top edge of the starter pieces
will allow a smooth and uniform transition for applied shingles.
1. Bottom Starter Course Layer: Cut 20" off the first bottom piece.
Apply remaining 131®4" x 20" piece, followed by full 131®4" x 40"
pieces along the eave. DO NOT REMOVE THE PERFORATED TOP
SECTION. Extend the shingles over the rake and eaves about 1®2"
(13 mm) if drip edge is used, or about 3®4" (19 mm) if no
drip edge is used.

Figure 15-15: Fourth Course.
SUCCEEDING COURSES: Start the Fifth Course by installing a full
shingle and repeat the four-course pattern. Continue applying
shingles filling into the right of the first four courses.
ANOTHER WAY TO VIEW IT:
The 5" and 15" offset pattern is established over the 4 courses
as follows:
1st course shingle = 40" L (full shingle)
2nd course shingle = 35" L (1st course 5")
3rd course shingle = 20" L (2nd course 15")
4th course shingle = 15" L (3rd course 5")
AN ALTERNATIVE TO STARTING ON THE LEFT:
Follow the same application instructions specified in the 5" and 15"
Offset Method above except instead of starting at the left rake, strike a
chalkline perpendicular to the eave, at least 10' from the rakes edge.
Install the First Course full shingle by aligning its left edge with the
perpendicular chalk-line. Follow the 5" and 15" Offset Method
instructions for the remaining courses.
IMPORTANT: The designed appearance and service of
Presidential Shake Shingles requires strict adherence to
the application instructions.
▲
Heres a Tipࡕ After establishing the 4 course shingle pattern, extend the 1st course by installing additional full shingles along
the eave. Using the proper alignment notch in the shingle course below to maintain the 5" and 15" offset,
build the courses up the roof by working back and forth across the roof deck. (Be careful to maintain the
correct offsets!)
▼
▲
Heres a Tipࡕ When establishing the 4-course shingle pattern, use the proper alignment notches to determine where to cut
the shingles on the left hand side. For example, install the first course full shingle, then place a full shingle above
it by lining up the right side edge with the 51/2" alignment notch in the 1st course shingle below, then fasten
and trim the 2nd course shingle along the rake edge. Likewise, use the 151/2" alignment notch at the top of the
2nd course shingle to place the right side edge of the 3rd course shingle.Finally, use the 51/2" alignment notch
at the top of the 3rd course shingle to place the 4th course shingle

DUAL COLOR APPLICATION METHODS
USING THE 5" AND 15" OFFSET
METHOD # 1 ALTERNATING COLORS SINGLE COURSES
1. Select color combinations of Presidential® Shake shingles for use
in dual color application, e.g. Slate Gray and Weathered Wood.
Color designations A and B for two different shingle colors
will be used in the following shingle application instructions.
2. STARTER COURSE: Apply color A Starter Strip shingles to
starter course and follow instructions for Starter Course
application.
3. 1ST COURSE: Apply color B Presidential Shake shingles to
the first course. Follow instructions for First Course application.
All shingles applied to the first course and all successive odd
numbers will be the same color i.e., color B.
4. 2ND COURSE: Apply color A shingles to second course.
Follow instructions for Second Course application. All shingles
applied to the second course and all successive even numbers
will be the same color i.e., color A.
5. Every other course of shingles will alternate between colors A
and B. Complete shingle application to each course across the
roof deck with the same color of shingles. To avoid confusion,
completely fill in each course of shingles across the deck at the
same time. Follow the appropriate installation instructions for
Presidential Shake shingles.
6. HIP & RIDGE: Apply hip & ridge cap shingles that are the oppo-
site color as that of the last course of Presidential Shake Shingle.
For example, if the last (top) course of Presidential Shake Shingle
is color A, then hip and ridge cap shingles should be color B.
METHOD #2 ALTERNATING COLORS DOUBLE COURSES
1. Select color combinations of Presidential Shake Shingles for use in
dual color application, e.g. Slate Gray and Weathered Wood. Color
designations A and B for two different shingle colors will be
used in the following shingle application instructions.
2. STARTER COURSE: Apply color A Starter Strip Shingles to
starter course and follow instructions for Starter Course
application.
3. 1ST COURSE: Apply color A Presidential Shake Shingles,
same color as starter shingles, to the first course. Follow
instructions for First Course application.
4. 2ND AND 3RD COURSE: Apply color B shingles to the
second and third courses. Follow instructions for Second Course
and Third Course applications.
5. 4TH AND 5TH COURSES: Apply color A shingles to the
fourth and fifth courses. Follow instructions for Fourth Course
and Fifth Course applications.
6. All succeeding courses continue with two courses of shingles of
one color followed by two courses of shingles of the other color.
To avoid confusion completely apply the two courses of same
colored shingles at the same time. Follow the appropriate
installation instructions for Presidential Shake shingles.
7. HIP & RIDGE: The hip & ridge shingle color to be used will
depend upon the color of the last two courses of Presidential
shingles. If the last two courses contain shingles of the same
color, then the hip & ridge color will be the opposite color.
For example, if the last two courses are color A, then the
color B hip & ridge shingles are used.
If the last two courses of shingles are different in color, then the
color of hip & ridge shingles will be the same as the last course of
Presidential Shake shingle. For example, if the next to last course
is color A and the last (top) course is color B, then the Hip &
Ridge color used is B.
▲
CAPPING THE HIP AND RIDGE
▼
Cedar Crest® or Mountain Ridge® accessory shingles can be used
for covering hips and ridges. Apply shingles up to the ridge. Fasten
each accessory with two fasteners. The fasteners must be 13®4" long
or longer, so they penetrate either 3®4" into the deck or completely
through the deck.
▲
MOUNTAIN RIDGE HIGH-PROFILE
HIP AND RIDGE ACCESSORY SHINGLES
▼
Use Mountain Ridge accessory shingles to cover hips, ridges or
rake edges. One box will cover 20 linear feet. To prevent damage to
shingles during application, they must be sufficiently warm to allow
proper forming.
FASTENING
IMPORTANT: Use two nails to fasten each shingle. Nails must be
minimum 13®4" (45 mm) long. For the 4" (100 mm) starter
shingle, place fastener 1" (25 mm) in from each side edge and
about 2" (50 mm) from the rake (or eave) edge, making sure the
fastener goes 3®4" into the deck or all the way through. For each
full accessory shingle, place fasteners 85®8" (219 mm) up from its
exposed butt edge and 1" (25 mm) in from each side edge.
▲
Heres a Tipࡕ To provide a level surface for hip and ridge caps applied over Presidential TL, a nailer made from 1-by boards
can be installed or a piece of metal can be formed to support the caps. Also ridge vents made from sturdy
material can serve as a base to provide an even uniform appearance.
▼
11/24/17
132 Chapter 15 CERTAINTEED SHINGLE APPLICATO R S MANUAL
HIP, RIDGE AND RAKE SHINGLE APPLICATION
Apply the primary field roofing up to the hip or ridge from both
sides of the roof and trim flush or lap over one side, not more than
half the width of an accessory shingle.
Assure that the installed accessory shingles properly cover field
shingles on both sides and along rake edges. For a rake edge
installation, cut the field shingles flush to the rake edge. Apply
accessory shingles ensuring they fit securely against the rake board.
To assist in proper alignment, snap a chalk line parallel to
the hip, ridge or rake along the line where the side edges
of the accessory shingles should fall.
Prepare a 4" Starter shingle by cutting off the lower 8" color
granule butt portion of one accessory shingle. Apply the 4" starter
piece (with sealant nearest the outer edge) over the bottom corner
of the hip or rake, or on either end of the ridge, overhanging
the corner or end by approximately 1®2" and bending the starter
shingle along its centerline to form into place (see figures below.)
Install a nail on each side about 2" up from the starter shingles
exposed butt edge and 1 in from each side edge of the shingle.
The 8 piece that was cut off may be used to finish the opposite
end of hip, ridge or rake.
Next, apply a full Mountain Ridge® shingle over the installed
starter shingle, bending it along its centerline and forming into place
over the hip, ridge or rake, flush with the bottom and side edges of
the starter shingle. Install a nail on each side of the shingle 85®8" up
from the bottom edge and 1" in from each side edge.
Continue application of the Mountain Ridge shingles along the hip,
ridge or rake as shown. Expose Mountain Ridge shingles 8", covering
all fasteners.

CEDAR CREST MEDIUM-PROFILE
HIP AND RIDGE ACCESSORY SHINGLES
▼
Cedar Crest® hip and ridge shingles deliver a thicker appearance to
accentuate the roof lines for a more attractive finish. Unlike other
accessory products which have a monotone appearance, Cedar Crest
has blended colors that complement the Landmark® Landmark TL,
Presidential® and Presidential TL shingle colors. Cedar Crests
multi-layer design gives additional protection at critical stress points
and its aggressive sealant helps ensure the caps stay on the roof.
Use Cedar Crest accessory shingles to cover hips and ridges.
Carefully separate the three-piece units prior to application, by
first folding along the pre-cut lines and then detatching the pieces
(see Figure 15-19). No cutting is necessary. There are 30 individual
shingles (10 three-piece units) in each bundle. One bundle will
cover 20 linear feet. Each 12" x 12" shingle has a shadowline that is
a design feature which is visible when applied properly. To prevent
shingle damage during application, they must be sufficiently warm to
allow proper forming.
Figure 15-19: Separate to make 3 cap shingles.
FASTENING
IMPORTANT: Use TWO nails to fasten each shingle. Fasteners must
be minimum 13®4" (45 mm) long.
For the starter shingle, place fastener 1" in from each side edge and
about 2" up from the starter shingles exposed butt edge, making sure
fastener goes 3®4" into the deck or all the way through the deck.
(see Figure 15-20). For each full Cedar Crest shingle, place fasteners
85®8" up from its exposed butt edge and 1" in from each side edge
(see Figure 15-21).

IMPORTANT: High Wind Instructions. In order to achieve the
ASTM D3161 Class F Wind Resistance Classification each hip and
ridge shingle must be both 1) fastened with nails as shown and
2) hand-sealed with two 1/4" (6 mm) wide beads of either BASF

3®4"-1" (19 mm 25 mm)
in from each side edge of
the shingles headlap as
shown. Immediately align
and apply the next overly-
ing shingle, gently pressing
tab sides into adhesive and
ensuring none becomes
visible. Only one side of thedouble thickness tab is laminated
together; to secure the other side, after folding the shingle over the
ridge and nailing into position, a 1" (25 mm) diameter spot of either
NP1 or PL adhesive must be applied between the shingle layers as
shown. Immediately align and apply the next overlying shingle, gently
pressing tab sides into adhesive and ensuring none becomes visible.
CEDAR CREST APPLICATION
Apply primary roofing up to hip or ridge on both sides of roof and trim
flush. Ensure that the Cedar Crest® shingles will adequately cover the
top course of the shingles on both sides of the hip or ridge. Prepare a
4" starter shingle by cutting off the lower 8" color granule portion of
one Cedar Crest shingle. Apply the 4" starter piece with raised overlay
edge over the bottom corner of the hip or to either end of the ridge,
overhanging the corner or end by approximately 1®2" and bending
the starter shingle along its centerline to form into place (see Figure
15-20). Install a nail on each side about 2" up from the starter shin-
gles exposed butt edge and 1" in from each side edge of the shingle.
Then apply a full 12" x 12" piece over the starter, bending the
shingle along its centerline and forming it into place over the hip
or ridge, flush with the bottom and side edges of the starter shingle.
Fasten with two nails minimum 13®4" long with one nail on each side
of shingle 85®8" up from the butt edge and 1" in from each
side edge (see Figure 15-21).

METAL STEP FLASHING
▼
Metal flashing must consist of a 5" x 6" piece, bent as shown in
Figure 15-23.
Place each piece of flashing 2" up the roof from where the
lowermost edge of the next (overlapping) shingle will be applied.
Each succeeding course of flashing must overlap the flashing course
below it a minimum of 2".

REROOFING
▼
TEAR-OFF
CertainTeed recommends but does not require old roofing be
removed before installation of these products. Inspect the condition
of the roof to determine that the load bearing capacity is adequate
for the application of the Presidential® shingles. If the old roof
consists of two or more layers of shingles, it is required to remove
(tear-off) the existing roofing. After tear-off, repair the decking and /
or install new decking and apply new underlayment, eaves flashing,
and Presidential shingles using the recommended procedure.
ROOF-OVER
OVER ASPHALT SHINGLES:
IMPORTANT: If Presidential shingles are applied over existing
roofing shingles, special nesting application methods must be
followed. Applied incorrectly, raised shingle edges may result which
can give an objectionable appearance and reduce the performance
of the roofing.
If Presidential Shake Shingles are installed over existing wood
shingles, replace old wood shingles along eave and rake edges
with 1" (25 mm) x 4" (102 mm) boards. Beveled wood strips
4" (102 mm) x 5" (127 mm) wide may be installed below butt of
shingles to provide a solid nailing base. Install Presidential Shake
shingles using the recommended procedures.
