19" SELVEDGE EDGE
ROLL ROOFING
This product is NOT to be used on slopes
less than 1 in. 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 ft. to 18 ft.
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 – Use lap cement meeting ASTM D
3019.
APPLICATION – Sheets are to be applied
horizontally from the eave to the ridge.
Begin by applying starter strips to the eave.
Remove the 17 in. granule-surface portion from a
sheet of selvedge roll roofing. Place the remaining
19 in. portion parallel to eave so that it overhangs
the drip edge 1/4 in. to 3/8 in. at both the eaves
and rakes. Fasten it to deck with 2 rows of nails
in the selvedge portion. Locate the first row 5
in. in from the side edge and the second row 9
in. in from the first with the nails spaced 12 in.
on center, slightly staggering them in each row.
Cover the entire starter strip with a thin layer of
cold application cement. Place full width sheet
over it, fastening with 2 rows of nails in selvedge
portion as shown in diagram below. Continue each
succeeding course, in the same manner, varying
the 12 ft. to 18 ft. sheet lengths to ensure that top
laps do not fall next to each other.
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.
Additional illustrations and installation details are
available in the Asphalt Roofing Manufacturers
Association Booklet, “Residential Asphalt Roofing
Manual”.
Position all laps so the upper sheet overlies the lower one,
thereby carrying drainage over the joint rather than into it.
Selvedge edge roll roofing may also be applied parallel to
the rakes.
