INSTALLATION PRINCIPLES
FASTENING
Start installaon at eave. Overlap
joints away from entrances
and/or away from the point of
greatest trac. This will improve
overall appearance.
Posion the dark strip “shadow
line” at the top.
Stagger each course at least one
corrugaon from previous piece.
Dierent visual eects can be
created by various staggers of
1, 2, or 3 corrugaons. Ensure
proper waterproong by aligning
the overlapping guides.
ONDUVILLA® is to be fastened
at each overlap and corrugaon
with ONDUVILLA® Fasteners.
Fasten the shingles following the
order described, between the 2
overlapping guides. Do not fasten
those corrugaons that will be
overlapped by the next shingle or
Verge Piece unl those pieces are
in place.

1st Course-Start at either rake, shingle can be installed in either direcon over properly prepared and installed sheathing,
underlayment, ice and water leak barrier, and edge trim. Begin by installing rst full shingle. Install shingle at rake posioning
so that Verge Piece aligns with rst corrugaon on shingle. You may need to inset shingle 1/4” to 1/2” in order to align rst
corrugaon with Verge Piece. If necessary overhang shingle no more than 1-1/2” over eave and drip edge trim. Closure Strips
should be used to close corrugaons. Fasten according to the fastening paern in the fastening schedule. On rst course, fasten
above the upper alignment line to ensure penetraon into the roof deck. Install addional shingles along eave by overlapping
one corrugaon and connue following fastener schedule to the opposite rake.
2nd course- Stagger each course a minimum of 1 corrugaon from the previous course by cung the shingle. Preferred method
is to alternate full shingle rst course and half shingle second course and connue alternang paern. Align at the rake edge
as before. Align the overlapping guide with the underlying shingle and fasten according to the fastener schedule. Connue
installing to the rake edge. Connue up slope with addional courses as needed. Make sure that shingles are aligned correctly
and running true following the desired stagger paern. Make sure fasteners are not over driven as it will cause the shingle to
deect and not overlap correctly.
