CAUTION
Installaon of roong materials can be
dangerous. The relave amount of danger
is increased by the height from the ground,
increasing pitches of the roof slope, inclement
weather condions or other factors. We strongly
recommend for anyone installing ONDURA-9,
or working on a roof in any manner, to take all
precauons possible to ensure your personal
safety at all mes.
Be sure that ladders and other such devices
are safely posioned and properly secured.
OSHA recommends the use of a safety harness
when applying roong. Protecve eyewear is
recommended when applying nails or using
power tools. ONDURA-9 may be slippery when
wet, dusty, frosty or oily, so please avoid working
or walking on the roof if any of these condions
exist. Windy condions can make the worksite
more dangerous, so we recommend that you do
not aempt to install ONDURA-9 during windy
condions.
You will need the following tools and materials:
n Claw Hammer
n Ulity Knife
n Saw (Hand Saw or Circular Saw)
n Measuring Tape or Yardsck
n String
n Pencil or Marker
n Protecve Eyewear

For projects requiring mulple sheets, account for overlaps in
calculang roof coverage (see diagram below).
n Sidelap should be at least one corrugaon
(4 inches per corrugaon).
n Headlap should be at least 7 inches.
n The eecve sheet coverage is 32 inches wide
by 72 inches long.

n Fasteners needed per sheet: 17 min./24 max.
for 3 rows of fasteners, with rows spaced
approximately 24 inches apart.
n Fasteners for roof ridge: 6 fasteners per foot
of ridge (3 on each side).
n Fasten sheets on every corrugaon at rake edge,
eaves, and overlaps. For other fastener rows you
may fasten on every corrugaon or on every other
corrugaon. Fastening on every corrugaon provides
beer wind resistance.
n Fasten ridge caps at every corrugaon.
