For example you would say:
Miles and miles of road
Tons and tons of food
How about when referring to the floor inside a house (given that the house is relatively big)?
[…] and […] of plywood floor
You would say:
Acres and acres of plywood floor
Because floorage is an areal measure.

Because I couldn’t see how the asker’s two exemplars of tons of food and miles of road made any literal (read: “literal-literal” as opposed to hyperbolic) sense in the case of your run-of-the-mill single-family home, I chose the answer that seemed best-matched to those two in scope and tenor.
For rather unlike scenarios, compare these two scenarios:
Do you new give homeowners a per-square-foot pricing break for hardwood flooring installations above a certain square footage?
Wow dude, you’ve got like acres and acres of hardwood floors here hidden under your wall-to-wall carpeting!
Don’t bother stopping at the grocery store: we’ve got tons of food here.
Gosh, your driveway is like miles long!
