WHEN APPLIED ACCORDING TO THIS DIA-
GRAM, THE PRODUCT COVERS 98.76 SQUARE
FEET WITH A 3" TOP LAP AND A 4" END LAP.
This product is NOT to be used on slopes less than
2" per horizontal foot.
ROOF DECK – Roof deck must be smooth, dry and
free from warped surfaces. It is recommended that
metal drip edges be installed at eaves and rakes.
UNROLL BEFORE APPLYING – Roofing should be
unrolled and allowed to lie flat in warm sunlight for
some time in advance of application. This allows the
material to relax, thereby minimizing the possibility
of buckles and surface unevenness. THE SHEET
SHOULD BE CUT IN 12' to 18' LENGTHS.
TEMPERATURE – Roofing must not be applied
when air temperature is below 50°F unless proper
pre cautions have been taken to allow for applica-
tion of the material.
ADHESIVE – TAMKO recommends TAMKO Cold
Method and Lap Cement and/or any cold applica-
tion cement meeting ASTM D 3019.
UNDERLAYMENT – TAMKO recommends the use
of underlayment with roll roofing. Apply asphalt
saturated felt as underlayment over the entire deck.
Apply horizontally, parallel to eaves, lapping each
course of the felt over lower course at least 2" and
where ends join, lap the felt 4".
APPLICATION - Place 9" side strips of roll roofing
along the eaves and rakes, positioning them to
overhang the deck 1/4" to 3/8". Fasten strips with
2 rows of nails as shown in diagram below. Posi-
tion a full-width strip of roofing so that edges are
flush with eaves and rakes. Fasten upper edge
with nails 4" on center and slightly staggered. Next
course should overlap nails a minimum of 1". Lift
lower edge of first course and cover edge firmly into
cement. Continue each succeeding course in the
same manner, varying 12' to 18' sheet lengths, so
that end laps do not line up with one another. Pay
close attention to the laps because proper sealing
is critical.
WARNING
All cement is to be applied in thin, smooth, even
layers. Excessive use of cement will cause blister-
ing of this prod uct. All nails should be covered. If
any nails remain exposed, cover them with plastic
asphalt roofing cement.
Additional illustrations and installation details are
available in the Asphalt Roofing Manufacturers
Association Booklet, “Residential Asphalt Roofing
Manual”.
Roll roofing may also be applied vertically, parallel
to the rakes.
