I have vinyl siding on my house, which is mostly brick. The siding is under
the eaves (hip roof).

I need more ventilation in the attic and may have to cut thru the vinyl and
plywood so that I can put in some kind of air vents for inflow into the
attic.

How difficult is it to cut vinyl siding? I would like to cut both siding
and plywood at the same time if I can.

If I cut the vinyl incorrectly, the siding cannot be replaced-that type is
no longer produced.

If necessary, I could remove a section of the siding and cut it separately.

Thanks.
