For what purpose? Around here it's installed on roofs to protect against
ice damming.
And per code it has to be installed up the roof plane from the lower edge
until
it's 2 feet past the inside heated space below. Maybe that's where your
2 feet is
coming from?

Here they want the membrane to cover the entire roof.
This is what I needed on my addition.

It is so, when the hurricane blows the shingles off, you still have a
roof.

Makes a lot more sense to have metal decking instead of stupid shingles.

About $20 thousand more.
