WHEN APPLIED ACCORDING TO THIS
WRAPPER DIAGRAM, THIS PRODUCT
COVERS 96 SQUARE FEET. FOR 100 SQUARE
FEET OF ROOF COVERAGE, USE A 2" 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 precautions have been taken to allow for
application of the material.
ADHESIVE – TAMKO recommends TAMKO
Cold Method and Lap Cement and/or any cold
application 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.
Position 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
blistering of this product. TAMKO Roofing
Products, Inc. will assume NO responsibility for
the blistering.
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.
