I looked up the Ontario code online, and maybe it was the format, but
I found it confusing and ambiguous. It clearly calls for eave
protection underlayment, but the wording for the rest of the roof is
unclear. Since both the Ontario and NY codes are based on the IRC,
they should have a lot of similarity. Not sure why there's such an
omission for the underlayment.



All I know is what I see, and I see a LOT around here. Not once, ever, have
I seen a new-home roofed with /any/ sort of underlayment, not even at the
eaves.
