USES

TAMKO SYNTHETIC SHIELD UNDERLAYMENT is intended

to perform the functions of an underlayment when installed

between the roof deck and the shingles or other ﬁnal roof

covering. TAMKO SYNTHETIC SHIELD UNDERLAYMENT

will not prevent wind driven rain from entering the building nor

should it be used as the primary roof covering. The ﬁnal roof

covering must be installed before the structure is exposed to

adverse weather conditions, such as wind driven rain, high

wind, hail, ice storms, etc. Failure to apply TAMKO SYNTHETIC

SHIELD UNDERLAYMENT properly and according to TAMKO’s

Application Instructions could adversely affect coverage under

the applicable Limited Warranty. TAMKO SYNTHETIC SHIELD

UNDERLAYMENT must not be exposed to UV rays for more

than 180 days.

SURFACE PREPARATION

Apply TAMKO SYNTHETIC SHIELD UNDERLAYMENT when

the deck is dry. To begin, remove any dust, dirt, loose nails

or other protrusions from the deck of new roofs. Remove all

shingles, rooﬁng felt, nails, or other existing rooﬁng materials

and debris from the deck of existing roofs.

Before walking on the underlayment surface, the TAMKO

SYNTHETIC SHIELD UNDERLAYMENT must be securely

fastened to the roof deck using corrosion-resistant nails or

staples with 1 in. round plastic caps. Fall protection devices

should be utilized. Moisture, frost or debris may decrease

the traction while walking on TAMKO SYNTHETIC SHIELD

UNDERLAYMENT.

FOR ROOF DECKS

Apply TAMKO SYNTHETIC SHIELD UNDERLAYMENT from low

to high in shingle fashion so that laps will shed water. Overlap

edge seams 3 in. as marked on the underlayment. End seams

must be overlapped 6 in. and staggered. Fasteners should

be placed in all marked locations but no farther than 12” from

end laps in the ﬁeld of the roof. The underlayment must be laid

out ﬂat with printed side up without wrinkles and fastened to

a smooth dry surface. Care must be taken not to damage the

surface of the underlayment. DO NOT stretch during installation.

FASTENING

Do not use nails or staples without round plastic caps.

Fasteners must be long enough to penetrate at least

3/4 in. into the roof deck. Use only corrosion resistant nails or

staples with 1 in. round plastic caps. Fasteners must be ﬂush

and at approximately a 90 degree angle to the roof deck. Follow

the nail pattern as marked on the underlayment.

See illustration for details. Fasteners on vertical and horizontal

laps must be spaced 6 in. on center.

For High Wind Application

requirements: Fasten the

underlayment at all nail

locations indicated by a cross.

Fasteners on vertical and

horizontal laps must be spaced

4 in. on center.

For Low Slope Application:

On pitches 2 in. per foot to 4 in. per foot, cover the deck with

two layers of TAMKO SYNTHETIC SHIELD UNDERLAYMENT.

Begin by applying the underlayment in a 24 in. wide strip

along the eaves and overhanging the drip edge by 1/4 to 3/4

in. Place a full 48 in. wide sheet over the 24 in. wide starter

piece, completely overlapping it. All succeeding courses will be

positioned to overlap the preceding course by 24 in. If winter

temperatures average 25°F or less, TAMKO’s Moisture Guard

Plus

self-adhering underlayment or any specialty eaves ﬂashing

product should be installed from eaves and rakes to a point to at

least 24 in. inside the interior wall line of the building.

FOR VALLEYS AND RIDGES

Center TAMKO SYNTHETIC SHIELD UNDERLAYMENT in

the valley or over the ridge, working from the center of the

valley or ridge outward in each direction. For valleys, apply the

underlayment starting at the lowest point and work upward.

Overlap all sheets in shingle fashion a minimum of 6 in.

PROVIDE VENTILATION WHEN USING

OVER THE ENTIRE ROOF DECK

When using TAMKO SYNTHETIC SHIELD UNDERLAYMENT

over the entire roof deck the roof must include a system to

provide adequate ventilation for all space immediately below

the roof deck. Such ventilation system should be designed in

accordance with architectural design standards appropriate to

the size, nature, and location of the structure and must include

both ridge and sofﬁt venting. For further information on providing

adequate ventilation, contact your architect, building contractor,

building materials supplier, or TAMKO.

It is the responsibility of the installer to ensure installation is

completed according to directions, and that all construction by-

laws and codes are met.
