the shingle making certain nails are covered by the next (successive)
course of shingles. Each shingle tab must be sealed underneath
with TAM-PRO® SBS Flashing Cement, TAMKO or TAM-PRO®
Plastic Roof Cement, or TAMKO Tam-Seal Adhesive immediately
upon installation. Quarter-sized dabs of cement or adhesive must be
applied to shingles with a 5 in. exposure, use 9 fasteners per shingle.
(See Mansard Fastening Pattern illustrated below).
MANSARD FASTENING PATTERN
3) High Wind Warranty Fastening Pattern. (For High Wind Warranty
Application requirements) One fastener 1-1/2" from each end. One
fastener 8-7/8" from each end and one fastener 16-1/4" from each
end for a total of six (6) fasteners per shingle. In addition to this shingle
fastening pattern requirement for High Wind Application, TAMKO also
requires the use of TAMKO starter shingles including sealant strip at
eaves and rakes. Alternatively, along rakes, cement shingles to the
underlayment and each other in a 4 in. (102 mm) width of TAM-PRO®
SBS Flashing Cement, TAMKO or TAM-PRO® Plastic Roof Cement,
or TAMKO Tam-Seal Adhesive. Caution: Apply ONLY a thin uniform
layer of adhesive less than 1/8 in. (3mm) thick. Excessive amounts can
cause blistering of the shingles and may soften the asphalt in certain
underlayments resulting in the asphalt flowing, dripping and staining.
High Wind Application is offered on new construction or complete
tear-off applications only. It is not offered for recover applications. If
High Wind Application requirements are not followed, the High Wind
Application Warranty MPH, as stated on Table I in the Limited Warranty,
reverts to the Standard Application Wind Warranty MPH limit. (See
High Wind Fastening Pattern illustrated below.)
HIGH WIND WARRANTY FASTENING PATTERN
NAILS: TAMKO recommends the use of nails as the preferred method
of application. Standard type roofing nails should be used. Nail
shanks should be made of minimum 12 gauge wire, and a minimum
head diameter of 3/8 in. Nails should be long enough to penetrate
3/4 in. into the roof deck. Where the deck is less than 3/4 in. thick,
the nails should be long enough to penetrate completely through
plywood decking and extend at least 1/8 in. through the roof deck.
Drive nail head flush with the shingle surface.

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.
Products which are acceptable for use as underlayment are:
Asphalt Saturated Felt Underlayments:
• SuperX 30™ Underlayment
• TAMKO No. 15 Asphalt Saturated Organic Felt
• Any TAMKO non-perforated asphalt saturated organic felt
• A non-perforated asphalt saturated organic felt which meets
ASTM: D226, Type I or II or ASTM D4869
Specialty Underlayments:
• Tam-Shield® Synthetic Underlayment or Synthetic Shield
Underlayment
• TAMKO TW Metal and Tile Underlayment, TW Underlayment
and Moisture Guard Plus® (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 in. per foot and greater apply the felt parallel to the eaves
lapping each course of the felt over the lower course at least
2 in. Where ends join, lap the felt 4 in. 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 in. per foot and greater apply
the underlayment parallel to the eaves in accordance
with underlayment written application instructions. The
underlayment should not be left exposed for a longer period of
time than is specified in the underlayments written application
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’s
Moisture Guard Plus
® , 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.
Substitute products as shingle underlayment should not be used.
