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

8 in. on center.

For High Wind Application requirements: Fasten the

underlayment at the additional nail locations that are marked

as dotted circles on the underlayment. 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 TAM-SHIELD

SYNTHETIC 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 TAM-SHIELD SYNTHETIC 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 TAM-SHIELD SYNTHETIC 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.

SAFETY PRECAUTION

Personal fall protection devices, safety glasses and

hearing protection should always be used when applying

TAM-SHIELD SYNTHETIC UNDERLAYMENT. Moisture,

frost or debris may decrease the traction while walking on

TAM-SHIELD SYNTHETIC UNDERLAYMENT. PLEASE

EXERCISE CAUTION DURING INSTALLATION.

USES

TAM-SHIELD SYNTHETIC UNDERLAYMENT is intended

to perform the functions of an underlayment when installed

between the roof deck and the shingles or other ﬁnal roof

covering. TAM-SHIELD SYNTHETIC 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 TAM-SHIELD

SYNTHETIC UNDERLAYMENT properly and according to

TAMKO’s Application Instructions could adversely affect

coverage under the applicable Limited Warranty. TAM-SHIELD

SYNTHETIC UNDERLAYMENT is not adversely affected by

UV rays for up to 180 days.

SURFACE PREPARATION

Apply TAM-SHIELD SYNTHETIC 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 TAM-SHIELD

SYNTHETIC 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 TAM-SHIELD SYNTHETIC

UNDERLAYMENT.

FOR ROOF DECKS

Apply TAM-SHIELD SYNTHETIC

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. 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.
