For resistance to wind upli,
the maximum distance from
the eave edge of a sheet to
the rst row of nails is 3.25
inches.
Install nails on the rst sheet
along the eave and rake
edges.
Tip: For each row of nails, install the rst two nails at
opposite sides of the sheet and aach a string line
between them—across the corrugaons—as a guide
for the posion of the other nails. Mark the posion
of the string on the crown of each corrugaon with a
pencil. Repeat for each row of nails.
Install nails at remaining posions, but do not fasten areas
which will be overlapped by other sheets.
Place next ONDURA-6V sheet into posion on roof.
n The sheets must overlap by at least one corrugaon along
the direcon of the eave.
n The sheets should overlap by at least 7 inches along the
direcon of the rake edge.
Install nails on the next sheet in the same manner as the
rst sheet.
For the last sheet in a row, install nails in the same paern as
previous sheets and in the nal corrugaon along the rake edge.
Drive each ONDURA nail only through the crown of a
corrugaon and perpendicular to the roof surface. Be careful
not to overdrive or underdrive the nail. The rubber washer on
the nail should be snugly in contact with the sheet. Slight hand
pressure on a nailed-down corrugaon should not separate the
sheet from washer contact.

For valleys, install a minimum 24˝wide metal valley ashing. Cut
sheets at an angle to t the valley; then turn over, and on the
undersides along the valley edge, caulk one corrugaon of the
ONDURA-6V eave closure strip, and place into the corrugaon.
Then put a 1/2˝ bead of caulking on the at side of the closure
strips and on the sheet between the closure strips. Turn sheets
right side up, carefully lay in place so caulked closures seat on
ashing, and nail in place at least 12˝ up from the center of
valley without puncturing the metal ashing.
