5. APPLICATION INSTRUCTIONS

STARTER COURSE: A starter course may consist of TAMKO

Shingle Starter,

TAMKO

10-inch Starter, TAMKO

Perforated Starter, or self-sealing 3-tab

shingles. If self-sealing 3-tab shingles are used, remove the exposed tab

portion and install with the factory applied adhesive adjacent to the eaves.

Attach the starter course with approved fasteners along a line parallel to and

1-1/2" to 3" above the eaves edge. The starter course should overhang the

eave edge 1/4" to 3/4" and the rake edge 3/8" to 3/4" if drip edge ﬂashing

is not used along the eaves or rakes. If drip edge ﬂashing is present, install

shingles even with the drip edge or overhang the starter course over the drip

edge up to 3/4". Minimizing overhang at eaves and rakes is recommended

to improve wind resistance of the installed system.

2 CUTS, 5 COURSES, NO-WASTE SHINGLE APPLICATION: Start the ﬁrst

course with a full-size shingle placed directly over the starter course. Cut

10-3/8" from a full shingle to form a shingle 29" long. Use this to start the

second course (see diagram below). Cut a 23" long shingle to start the

third course. Use the remaining 16-3/8" piece of shingle to start the fourth

course and use the remaining 10-3/8" piece to begin the ﬁfth course.

Continue up the rake in as many rows as necessary using the same formula

as outlined below.

For maximum wind resistance along rakes, install any

TAMKO starter shingle including sealant or cement shingles

to the underlayment and each other in a 4" width of any

adhesive meeting ASTM D4586, Type 1.

4. UNDERLAYMENT

UNDERLAYMENT: An underlayment must be applied over the entire deck

before the installation of TAMKO

shingles. Failure to add underlayment can

cause premature failure of the shingles, which is not covered by TAMKO’s

Limited Warranty and Arbitration Agreement.

Products which are acceptable for use as underlayment are:

Asphalt Saturated Felt Underlayments

• Any TAMKO

non-perforated asphalt saturated organic felt

• A non-perforated asphalt saturated organic felt which meets

ASTM D226 or ASTM D4869

Specialty Underlayments

• Synthetic Guard

Plus Underlayment or Synthetic Guard

Underlayment

• A polymeric underlayment designed for use with

asphalt shingles which meets ASTM D8257

• TAMKO

Moisture Guard

Ice & Rain Underlayment

TW Underlayment or TW Metal and Tile Underlayment

(additional ventilation may be required—contact TAMKO’s

Technical Services Department for more information)

• A self-adhesive underlayment designed for use with

asphalt shingles which meets ASTM D1970

For Asphalt Saturated Felt Underlayments

Apply the felt when the deck is dry. On roof decks with slopes 4"

per foot and greater apply the felt parallel to the eaves lapping

each course of the felt over the lower course at least 2". Where

ends join, lap the felt 4". If left exposed, the felt may be adversely

affected by moisture and weathering. Laying of the felt and the

shingle application must be done together.

For All Other Specialty Underlayments

On roof decks with slopes 4" per foot and greater, apply

the underlayment parallel to the eaves in accordance with

underlayment application written instructions. The underlayment

should not be left exposed for a longer period of time than is

speciﬁed in the underlayment application written instructions.

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.

In areas where ice builds up along the eaves or a back-up of water from

frozen or clogged gutters is a potential problem, TAMKO

Moisture Guard

TW Metal and Tile Underlayment or TW Underlayment (or any specialty eaves

ﬂashing product) may be applied to eaves, rakes, ridges, valleys, around

chimneys, skylights or dormers to help prevent water damage. Contact

TAMKO’s Technical Services Department for more information.
