(CONTINUED from page 1)
2) Mansard Fastening Pattern. (For use on decks with slopes
greater than 21 in. per foot.) One fastener 1 in. from each end and one
fastener 10-1/2 in. from each end and one fastener 13-1/2 in. back
from each end for a total of 6 fasteners per shingle. (See Mansard
and High Wind Fastening Pattern illustrated below.)
MANSARD AND HIGH WIND FASTENING PATTERN
3) High Wind Fastening Pattern. (For High Wind Application
requirements) One fastener 1 in. from each end. One fastener 10-
1/2 in. from each end and one fastener 13-1/2 in. 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. 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 Mansard and High Wind Fastening
Pattern illustrated above.)
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.
STAPLES: If staples are used in the attaching process, follow the
above instructions for placement. All staples must be driven with
pneumatic staplers. The staple must meet the following minimum
dimensional requirements. Staples must be made from a minimum
16 gauge galvanized wire. Crown width must be at least 15/16 in.
(staple crown width is measured outside the legs). Leg length should
be a minimum of 1-1/4 in. for new construction and 1-1/2 in. for
reroofing thus allowing a minimum deck penetration of 3/4 in. The
crown of the staple must be parallel to the length of the shingle.
The staple crown should be driven flush with the shingle surface.
Staples that are crooked, underdriven or overdriven are considered
improperly applied.
CAUTION: ALL FASTENERS MUST BE DRIVEN INTO THE
NAIL ZONE/COMMON BOND AS SHOWN IN THE FASTENING
PATTERN DIAGRAMS.
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:
• 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:
• TAMKO Peel-N-Stick Felt
• Tam-Shield™ Synthetic 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.)
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.
