Engineering Certificate
Note 18
General conditions
Note 18.1
Note 18.2
Note 18.3
Note 19
Spacings on Tile Interfaces will be reduced as follows:
Note 20
Note 21
Note 22
Note 23
Note 24
A minimum of two (2) screws per Tile Interface will be required for installation.
If
any
of
the
screws
of
the
interfaces
go
into
pre
‐
existing
holes,
they
will
have
to
be
one
size
up
compared
to
the
screws
that
were
previously
installed.
This
is
to
ensure
that
the
pullout
capacity
remains
the
same
or
higher.

-
When using Roof Extender (ER-RE-200), reduce interface spacings by 15% on Wind Region A
and B and 30% on Wind Region C and D.
