INSTALLATION PRINCIPLES
FASTENING
Start installaon at eave. Overlap
joints away from entrances
and/or away from the point of
greatest trac. This will improve
overall appearance.
Posion the dark strip “shadow
line” at the top.
Stagger each course at least one
corrugaon from previous piece.
Dierent visual eects can be
created by various staggers of
1, 2, or 3 corrugaons. Ensure
proper waterproong by aligning
the overlapping guides.
ONDUVILLA® is to be fastened
at each overlap and corrugaon
with ONDUVILLA® Fasteners.
Fasten the shingles following the
order described, between the 2
overlapping guides. Do not fasten
those corrugaons that will be
overlapped by the next shingle or
Verge Piece unl those pieces are
in place.

1st Course-Start at either rake, shingle can be installed in either direcon 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 posioning
so that Verge Piece aligns with rst corrugaon on shingle. You may need to inset shingle 1/4” to 1/2” in order to align rst
corrugaon 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 corrugaons. Fasten according to the fastening paern in the fastening schedule. On rst course, fasten
above the upper alignment line to ensure penetraon into the roof deck. Install addional shingles along eave by overlapping
one corrugaon and connue following fastener schedule to the opposite rake.
2nd course- Stagger each course a minimum of 1 corrugaon from the previous course by cung the shingle. Preferred method
is to alternate full shingle rst course and half shingle second course and connue alternang paern. Align at the rake edge
as before. Align the overlapping guide with the underlying shingle and fasten according to the fastener schedule. Connue
installing to the rake edge. Connue up slope with addional courses as needed. Make sure that shingles are aligned correctly
and running true following the desired stagger paern. Make sure fasteners are not over driven as it will cause the shingle to
deect and not overlap correctly.
