MALARKEY LAMINATE SHINGLE INSTALLATION INSTRUCTIONS

Residential (Building) Code, Section R905.2.8.5, drip edge

ashing (drip edge, eave or rake metal) is required along the

eave and rake edges of shingle roofs.

Install drip edge rst along the eaves, and later on the rakes

once the eld underlayment has been applied.

UNDERLAYMENT

Malarkey makes two types of underlayment, the rst being

water-resistant, mechanically-attached eld underlayments

Right Start

™

UDL and our Secure Start

line of synthetic

underlayments.

The second type are waterproof, self-adhering underlay-

ments, Arctic Seal

and Secure Start

HT products which are

intended for use in cold weather climates that produce ice

dams.

Self-adhering underlayment can also be installed as a ashing

membrane in areas susceptible to leaks such as roof valleys,

roof-to-vertical transitions, and around vents, curbs, skylights

and other roof penetrations.

Underlayment is required on roof decks prior to the installation

of Malarkey shingles. Your geographical location, weather,

degree of roof slope, and type of roof covering will help deter-

mine which Malarkey underlayment is right for your situation.

Consult local building code for additional guidance.

Complete installation instructions are available on our website

at WWW.MALARKEYROOFING.COM.

Other Instructions Common to the Installations that

Follow:

• Underlayment is installed parallel to the eaves.

• End laps in the same course should be 6" (152mm), and

staggered 6' (1.8 m) apart in subsequent courses.

• Extend eld underlayments 6" (152 mm) over hips, ridges

and valleys. Where the roof meets a vertical surface, run

the underlayment a minimum of 3" (76mm) up the wall

and secure.

• Once an expanse of roof is covered by underlayment up

to the ridge, apply drip edge ashing to the rakes, over

the ends of underlayment.

INSTALLATION IN NON-ICE DAM REGIONS

Roof Slopes 4:12 and Greater

Roof slopes 4:12 (4" [102 mm] per 12" [305 mm]) and greater

require the installation of a single (1) layer of Malarkey’s eld

underlayment (or code-compliant equivalent) over the entire

roof deck.

Install the initial course ush to the eave and trim at the rake.

Fasten sufciently to hold the underlayment in place and work

safely until shingles are applied or according to adopted build-

ing code. Secure Start

underlayments have bullseye imprints

on the material to act as guides for fastening.

Continue working up the roof, subsequent courses overlap-

ping the preceding by 2"- 4" (51-102 mm), depending on the

type of underlayment being applied. (See Figure 1)

GENERAL INSTRUCTIONS

Install Malarkey laminate shingles according to adopted

building code and local amendments. To qualify for war-

ranty protection and obtain stated coverage, the installa-

tion instructions detailed here must be followed. Contact

Malarkey Technical Services or check our website at WWW.

MALARKEYROOFING.COM for the most current version.

We assume no responsibility when there has been improper

application, failure to properly prepare the surface or provide

proper ventilation according to FHA or HUD minimum prop-

erty standard requirements and adopted building code.

For current warranty information, visit

WWW.MALARKEYROOFING.COM/warranties.

Standard exposure is 5

⁄88"(143 mm) to the weather. Offset

between courses is 8" (203mm). Minimum offset for shingle

installation is 4" (102mm).

These step-by-step application instructions apply to standard

slopes/inclines of not less than 4" (102mm) per 12" (305 mm)

or more than 21" (533mm) per 12" (305 mm). For lower

slopes [2" (51mm) to less than 4" (102mm) per 12" (305 mm)]

and steep slopes [more than 21" (533 mm) per 12" (305 mm)],

modify the installation as described below. Do not apply

shingles on roofs having a slope less than 2" (51 mm) per 12"

(305mm).

Note: The lm strips on each shingle, front and back, prevent

shingles from sticking together while in the bundle and are not

designed to be removed.

IMPORTANT

• ALWAYS wear fall protection when working on a roof.

• Underlayments can be slippery, particularly when wet or

covered with frost. Be careful when walking on them.

Ventilation: To prevent harmful condensation or heat buildup,

air must circulate freely under the roof deck. Install roof vents

at ridges and eaves. Ventilation provisions must meet or

exceed current FHA or HUD requirements and adopted build-

ing codes.

Roof Deck: The surface to receive the new roong should be

in good shape and solidly sheathed, constructed of a mini-

mum

⁄88" (10 mm) thick, exterior-grade plywood,

⁄1616" (11 mm)

thick oriented strand board (OSB), or seasoned lumber,

nominally 1" (25 mm) thick. Boards should be positioned

tight to each other and securely nailed to framing members.

Deteriorated or rotted boards should be replaced. For exces-

sively resinous areas and loose knots, cover with sheet metal

patches.

Malarkey strongly recommends installing sheathing when

wood board decking is the existing substrate. Problems with

the performance of your roong system, such as leaks and

buckling, increase if installed directly over wood board decks.

Failure to use properly conditioned deck materials can result

in deck movement which can damage the roof covering and

may void your warranty.

Drip Edge Flashing: In accordance with 2018 International

Building Code, Section 1507.2.8.3, and 2018 International

MALARKEY LAMINATE SHINGLE INSTALLATION INSTRUCTIONS

When choosing this option, make sure proper ventilation and

moisture control issues are addressed.

INSTALLATION IN ICE DAM REGIONS

Roof Slopes 4:12 and Greater

In geographic regions that experience the possibility of ice

dams along the eaves (or if required by building code), install

a full-width sheet of self-adhering underlayment (or equivalent

underlayment conforming to ASTM D1970) along the eaves.

Continue installing self-adhering underlayment up and out

onto the roof no less than 24" (610 mm) past the inside, warm

interior wall of the house or above the expected level of ice

dams or according to building code requirements.

If additional courses of self-adhering underlayment are nec-

essary to reach that point, course lap guide lines (lay lines) on

the sheets show how far to lap the material. Firmly hand-roll

these overlaps to ensure a complete, watertight bond.

Once past 24" (610 mm), follow with full-width courses of

your specied eld underlayment, the rst course lapped 6"

(152 mm) over the termination of self-adhering underlayment

and the rest with 2"- 4" (51-102 mm) side laps, depending on

the type of underlayment being applied. Lay lines show how

far to lap the material.

Fasten as described above.

For extra protection at the eaves and prior to the installation

of drip edge, install a 6"-wide (152 mm) stripping ply of Arctic

Seal

, and ensure it covers the junction of roof and fascia.

Continue application up and out onto the roof as necessary to

a point not less than 24" (610 mm) past the inside, warm inte-

rior wall of the house or above the expected level of ice dams

or according to building code requirements.

Once that point is reached, switch to double layers of your

For a double layer, start at a lower corner of roof and begin

by applying a half-width starter strip of eld underlayment (or

code-compliant equivalent) along the eaves.

Succeeding courses are all full-width, the rst course com-

pletely overlapping the starter, and followed by courses half-

lapped over preceding courses, on up the roof.

MALARKEY LAMINATE SHINGLE INSTALLATION INSTRUCTIONS

Nailing Pattern: Under normal conditions, use four (4) fasten-

ers for each full shingle.

Malarkey laminate shingles feature The Zone

, an enlarged,

/16" (33 mm) wide nailing area that helps ensure correct fas-

tener placement. Place fasteners in this nailing area approx-

imately 1" (25 mm) in from each edge and the remaining

fasteners evenly spaced between. (See Figure 6)

5-5/8"

EVENLY SPACED

Figure 6 - Laminate, 4-Nail Fastening Pattern

Wind Resistance and Hand-Sealing: Malarkey shingles are

manufactured with strips of a factory-applied, thermal sealant

that is activated by the heat of the sun after the shingle is on

the roof. Exposure to the sun’s heat bonds each shingle to the

one below for wind resistance.

A variety of conditions like cold weather, high winds or blow-

ing dust, however, can affect the ability of the sealant strip

to activate and prevent shingles from self-sealing during, or

shortly after, installation. If shingles have not sealed after a

reasonable time period, hand-sealing (also called hand-tab-

bing) is strongly recommended.

Note: Malarkey’s wind warranties apply only when shingles are

sealed, whether by hand-sealing or activation of the self-seal-

ing strips. Failure to seal under adverse circumstances like

those described above is not a manufacturing defect.

To hand-seal a shingle, apply four (4) quarter-size dabs of

asphalt roof cement conforming to ASTM D4586 evenly

spaced under each shingle, and press shingles rmly into the

cement. Excessive use may cause blistering; correct amounts

should not bleed out from under the shingle. (See Figure 7)

EVENLY SPACED

Figure 7 - Hand-Sealing Laminate Shingles

Steep Slope Fastening of Laminate Shingles: Roof decks

with slopes greater than 21" (533 mm) per 12" (305mm)

require installation with six (6) fasteners per shingle and

hand-sealing underneath.

Two methods for fastening can be used, but for each, the

outer fasteners must be placed in the nailing area approxi-

mately 1" (25mm) in from each edge. The rst method has the

remaining four (4) fasteners also placed in the nailing area and

evenly spaced between. (See Figure 8)

Succeeding courses are full-width, the rst course completely

overlapping the starter, and followed by courses half-lapped

over preceding courses, on up the roof.

Fasten as described above. (SeeFigure 4)

SHINGLE FASTENING

Type of Fasteners: Fasteners must be minimum 12-gauge

(0.105inch [3 mm]) shank, galvanized steel, stainless steel,

aluminum or copper roong nails, with a

⁄88" (10mm) head,

compliant with ASTM F1667, and long enough to penetrate

through all layers of roong materials and at least ¾" (19 mm)

into the roof sheathing. Where the roof sheathing is less than

¾" (19 mm) thick, the fasteners shall penetrate through the

sheathing.

Malarkey approves the use of hand-nailing and/or pneumatic

nailers for applying fasteners, but nails must be driven ush

to the shingle surface and not overdriven, underdriven or

driven at an angle, especially on low slope installations where

water runs off less freely and leaks could result. When fasten-

ing adjacent shingles, butt them loosely together to prevent

buckling.

The use of staples is not an approved fastening method.

the remaining two evenly spaced on the same line as the end

fasteners. Do not place fasteners in the seal-down strip.

Continue across the eave with full-length starter shingles,

butting them loosely together to prevent buckling.

First Course of Shingles: Start the rst course with a full-

length shingle laid directly over the starter course.

Begin at the same lower corner of roof and apply ush with

the edges of the starter course on both eave and rake sides

(maintaining the ¼"- ¾" [6 -19 mm] roof overhang).

Fasten as described in the Shingle Fastening section above.

Second through Succeeding Courses: Start the second

course with a shingle from which 8" (203 mm) has been cut

from one end.

Position the remaining piece over the underlying, rst course

shingle, and align the bottom edge along a line level with the

“sawtooth” overlay, leaving an exposure of 5

⁄88" (143 mm).

Secure with fasteners.

Courses three through ve are begun with partial shingles,

each progressively 8" (203 mm) shorter, establishing the over-

all diagonal pattern. Pieces cut from shingles along the left

rake can be used either to continue the diagonal installation

pattern or nish off courses at the right rake.

Apply a full-length shingle adjacent to each of the rst ve

courses to extend the pattern. Join the shingles loosely

together to prevent buckling. Butt factory edge to factory

edge when installing the stairstep method. This helps maintain

a straight layout of the remaining shingles.

The sixth course begins again with a full length shingle, so

repeat the 1-to-5 course cycle on up the roof.

Shingles may be laid from either lower corner of roof;

follow layout and cutting instructions as required for proper

application.

Note: Other shingle offsets are acceptable but no less than 4"

(102 mm). Straight up application of shingles, or racking, is not

recommended.

CONSTRUCTING ROOF VALLEYS

Similar to a roof deck being prepared for shingles by rst

applying an underlayment, roof valleys must be likewise pre-

pared before they can be “constructed” with shingles.

Closed-cut and Open Metal Valley applications are recom-

mended for laminate shingles (instructions to follow); the Open

Membrane Valley style is also acceptable.

SHINGLE PATTERN LAYOUT AND APPLICATION

Important: The diagonal application procedures described

below are necessary to prevent objectionable patterning.

Malarkey is not responsible for such patterning on roofs where

this diagonal application is not used. Exposures should be

even along the courses as well, or an objectionable appear-

ance may occur.

Malarkey Smart Start

Starter Shingles: Smart Start

starter

shingles are designed to be separated lengthwise at a per-

foration so you get two, full-size starter shingles in one. The

perforation is in the middle of the shingle, 8

⁄16" (208 mm) from

each edge, and both pieces have seal-down strips. Besides

eaves, it is recommended Smart Start

starter shingles be

installed on the rake edges of roof to provide a clean edge

and increase wind resistance.

LAMINATE SHINGLE PATTERN LAYOUT (8" [203 MM]

OFFSET, FIVE COURSE DIAGONAL METHOD)

Starter Course: Install Malarkey Smart Start

starter shingles

or equivalent conforming to ASTM D3462. Ensure they are

positioned with the factory-applied sealant strip face up and

the strip adjacent to the eave edge of roof.

Cut 6" (152 mm) off one end of the rst starter shingle, and lay

it on a lower corner of the roof, overhanging the rake and eave

edges by ¼"- ¾" (6 -19 mm).

Fasten with 4 nails, 1½"- 3" (38-76 mm) up from the eave,

with one fastener 1" (25 mm) from each side of the starter and

MALARKEY LAMINATE SHINGLE INSTALLATION INSTRUCTIONS

Open Metal Valley Construction: Metal valley ashing

(“valley metal”) used with Malarkey shingles must be minimum

24" (610 mm) wide and 26 gauge. Preformed, “W”-shaped

ashing is recommended.

Center the valley metal over the valley liner, press it into the

break of the valley, and secure with fasteners no more than 1"

(25 mm) from the outside edges at a spacing of 10" (254 mm)

to 12" (305 mm) O.C.

Set overlapping ends of the valley metal in a continuous bead

of sealant, achieving a lap of 4" (102 mm). DO NOT FASTEN

THE METAL LAP.

For additional sealing, a continuous 6" (152 mm) strip of

self-adhering Arctic Seal

may be applied over the fasteners

on each side of the valley metal.

Never use a shingle trimmed to less than 12" (305 mm) in

length to nish a course running into a valley. If necessary,

trim a tab off the adjacent shingle in the course to allow a

longer portion to be used. Make sure each shingle extends far

enough into the valley so in a future step, a shingle’s full width

(or height) will be trimmed back.

Nail no closer than 6" (152 mm) to the valley centerline.

Now, trim shingles a minimum of 2" (51 mm) back from the

centerline, cut the ends diagonally to match the centerline

angle, and crop the top of each shingle at a 1" (25 mm), 45

degree cut.

Embed the ends of the cut valley shingles in a continu ous

3" (76 mm) wide bead of asphalt roof cement conforming to

ASTM D4586, and press them into the adhesive.

FLASHING APPLICATIONS

Intersections of Roof and Vertical Sidewall: Minimum

26-gauge, metal step ashing is used in the junction between

a sloping roof and intersecting sidewall (on a dormer, for

example) to protect this vulnerable area from moisture

intrusion.

Step ashing can be square or rectangular, but 8-inch

(203 mm) by 8-inch (203 mm) dimensions are common and

satisfactory for our purposes.

Being 8" wide allows the ashing to be bent at 90 degrees

and pushed against the transition of roof to wall, the horizon-

tal ange extending 4" (127 mm) out onto the roof deck and

the vertical ange, 4" (127 mm) up the wall assembly. Being

in the valley, and apply it directly to the roof deck. Ensure this

valley liner is tight to the deck without bridging in the center of

the valley.

Field underlayment can be woven across the valley liner and

up the opposite side at least 12" (305 mm) or lapped over

each side a minimum of 6" (152 mm). When fastening, be

aware no fasteners are allowed within 6" (152 mm) of the

valley centerline.

Valley underlayment must be in place for each method

described next.

Closed-Cut Valley Construction: Lay a rst course of

shingles along the eave on one side of the roof, and continue

it across the valley and onto the adjoining roof at least 12"

(305mm). Do not make a joint in the valley. Should a shingle

fall short, add-in one or two tab sections so the joint falls out-

side the line of the valley.

Press the shingles well into the break of the valley, and nail

using normal fastening methods, remembering no fasteners

are allowed closer than 6" (152 mm) to the valley centerline.

Besides the nails used to secure the shingle, add another

in the upper corner at the end of each shingle crossing the

valley.

Repeat these procedures with the rst course of shingles on

the intersecting roof, extending it across the valley, over the

top of the shingles laid before, and at least 12" (305 mm) onto

the adjoining roof surface. Press into the valley, and fasten as

before.

Note: The rst course of shingles are the only ones woven in

this fashion.

Return to the side of the roof you began with, and resume

laying shingle courses across the valley and onto the adjoining

roof at least 12" (305 mm). Complete the installation of shin-

gles on that roof section.

Snap a chalk line 2" (51 mm) from the centerline of the valley

on the unshingled side. Begin applying shingle courses on the

unshingled side, trimming them diagonally at the chalk line to

match the centerline angle, and cropping the upper corner of

the last shingle at a 1" (25 mm), 45 degree cut. Doing this will

direct water into the valley.

Embed the ends of the cut valley shingles in a continu ous

3" (76mm) wide bead of asphalt roof cement conforming to

ASTM D4586, and press them into the adhesive.

Complete the installation of shingles on that roof section.

used to secure the anges, and tying onto the eld underlay-

ment a minimum of 3" (76 mm).

Continue roong around the pipe, cutting shingles to t on the

sides and top of the pipe jack anges. Ensure shingles extend

beyond the downslope side of the pipe itself. Shingles that

overlap any part of the anges should be sealed to the ange

with asphalt roof cement conforming to ASTM D4586. Correct

amounts should not bleed out from under the shingles; exces-

sive use may cause blistering. Apply pressure to seal.

Cap (Counter) and Chimney Flashings: The metal ashing

apron for the front of the chimney shall be installed over the

last course of shingles below the chimney and its vertical

ange extending up the face of the chimney.

The metal ashings of chimneys, skylights, vents, and adjoin-

ing walls must be counter-ashed with sheet metal cap

ashing.

Cap ashing (also called counter ashing) should originate in

the masonry mortar joints of the chimney and be mortared-in

or caulked with urethane sealant to ensure a watertight

connection.

Cap ashing should then turn down the chimney and extend

a minimum of 2" (51 mm) over the step ashings at all roof-to-

sidewall intersections. (See Figure 15)

8" long allows individual step ashing pieces to overlap each

other in water-shedding fashion as they are installed.

Individual step ashing pieces are integrated with each course

of shingles as they are applied to intersect the sidewall. A ¼"-

¾" (6 -19 mm) gap between the shingles and vertical bend of

the ashing is recommended.

To allow for possible roof movement, fasten each piece of

ashing to the roof deck and not the sidewall.

Installation is as follows: Atop the Smart Start

starter

course at the eave, place the rst piece of ashing*. The hori-

zontal ange should be ush with the eave edge of the starter

and the vertical ange against the sidewall, counter-ashed by

the wall cladding.

Fasten the horizontal ange of the step ashing to the roof

deck with two nails placed 1" (25 mm) from the upper edge

and spaced an equal distance apart.

Lay a rst course shingle down on the roof, positioning it close

to the sidewall but leaving a ¼"- ¾" (6-19 mm) gap between

the end of the shingle and vertical bend in the step ashing.

Fasten in place. The horizontal ange of the ashing will no

longer be visible, but you can still see the vertical ange along

the sidewall.

Place the second step ashing atop the rst course shingle,

and position it up from the eave edge of the shingle, matching

the shingle exposure, and fasten as before.

Lay a second course shingle on the roof, position leaving a

gap, and fasten.

Place the third step ashing atop that, overlapping the end

of the previous step ashing at the point of shingle exposure

(overlap is typically 2" [51 mm]).

Continue like this on up to the top of the sidewall intersec-

tion, alternating between the placement of step ashing and

shingles.

* The “rst piece of ashing” in this instance might well be

“kickout” ashing, a piece of ashing cut and angled to direct

MALARKEY LAMINATE SHINGLE INSTALLATION INSTRUCTIONS

Malarkey hip and ridge shingles also include a factory-ap-

plied, thermally activated seal-down adhesive that provides

additional protection against blow-off. When applied in cold

weather or a windy location, however, it is recommended each

ridge shingle be hand-sealed under each lower corner with a

quarter-size spot of asphalt roof cement conforming to ASTM

D4586.

To avoid damage to hip and ridge shingles in cold weather,

Malarkey recommends warming them sufciently to prevent

damage during installation.

Apply Malarkey hip and ridge shingles beginning at the

bottom of the hip or from the end of the ridge opposite the

direction of prevailing winds.

Snapping a chalk line will help maintain a straight line while

installing ridge shingles.

LOW-PROFILE INSTALLATION (10" AND 12" RIDGEFLEX

HIP AND RIDGE SHINGLES)

Prepare for application by separating each hip and ridge

shingle at the perforations: The 10" RidgeFlex

produces

four (4) individual hip and ridge strips (see Figure 17), and the

12" RidgeFlex

produces three (3) (see Figure 18). Note the

seal-down strips.

HIPS AND RIDGES

Factory-produced, Malarkey hip and ridge shingles are

recommended for all Malarkey shingle roofs and required for

expanded warranty coverage. Some contractors adapt 3-tab

roong shingles to use as hip and ridge shingles, but Malarkey

only allows this when the eld shingle is also a 3-tab shingle.

Shingles with Scotchgard

HIGH-PROFILE INSTALLATION (EZ-RIDGE

AND

EZ-RIDGE

XT HIP AND RIDGE SHINGLES)

Malarkey’s EZ-Ridge

is a high-prole hip and ridge shingle

specially designed to accompany laminate and designer shin-

gle applications.

Detail drawings to follow in this section show the installation

of shingles along a roof ridge, but hips are essentially the

same. Instructions for installing along rake edges are at the

end of the section.

Given the added thickness of EZ-Ridge

shingles, ensure your

fasteners are long enough to penetrate all layers and at least

¾" (19 mm) into the roof sheathing. Where the roof sheathing

is less than ¾" (19 mm) thick, the fasteners shall penetrate

through the sheathing.

Application begins at the bottom of the hip or from the end of

the ridge opposite the direction of prevailing winds with a hip

and ridge starter shingle.

EZ-Ridge

Starter Shingle: To create an EZ-Ridge

starter

shingle, cut off the 8¼" (210 mm) exposure portion of the

shingle, and use the remaining 3¼" (83 mm) cutout portion

(with sealant strip) as the starter. (See Figure 24)

Figure 24 - Cutting an EZ-Ridge

Shingle

to Make a Hip and Ridge Starter Shingle

Save the exposure portion because it can be used as the end

piece on the opposite end of the ridge.

Note: The longer strip on the end of an EZ-Ridge

shingle is

a lm strip that prevents the shingles from sticking together

while in the box they’re packaged in. It is not designed to be

removed.

Place the EZ-Ridge

starter shingle ush to the rake at the

peak, and position it so the seal-down strip is adjacent to the

roof edge. Push down on the center of the shingle and adjust

to t the pitch of roof.

Fasten with two (2) nails, one (1) on each side, ¾" (19mm)

behind the cutout and ½" (13 mm) up from the side. If installed

MALARKEY LAMINATE SHINGLE INSTALLATION INSTRUCTIONS

Make the surface as smooth as possible by replacing missing

shingles and securely nailing all buckles, raised tabs or curled

shingles. Malarkey is not responsible for a potentially objec-

tionable appearance of the new surface from any irregularity in

the substrate caused by remaining roong.

Additional ventilation should be provided, and longer nails will

likely be necessary to penetrate a minimum of ¾" (19 mm)

into the roof deck or completely through plywood or OSB

sheathing.

Installing Class 3 or Class 4 impact resistant shingles over

existing roofs negates their impact resistance and will not

make them eligible for insurance discounts.

These instructions are meant to act as a general guide. If you

RE-ROOFING OVER EXISTING ASPHALT SHINGLES

For best performance and appearance, it is recom mended old

roong be completely removed from the deck.

When roong over existing asphalt shingles, it is recom-

mended only 3-tab shingles be overlaid. Roong over lam-

inates creates an irregular surface across each course that

may prevent the newly installed shingles from sealing down

properly, leaving them more susceptible to wind damage.

In some areas, building codes do not require removal of old

roong if: 1) The existing shingles and framing will support the

workers installing the roong, the new roof itself, and required

dead loads; and 2) The old wood deck is sound and able to

provide good anchorage for nails.
