1. A roofing shingle comprising:
a substrate having a first surface and an opposing second surface;
a polymer-modified asphalt coating on the first surface of the substrate, wherein the polymer-modified asphalt comprises:
from 40 wt. % to 80 wt. % of a filler, based on the total weight of the polymer-modified asphalt coating,
from 1 wt. % to 13 wt. % of a polymer additive, based on the total weight of a non-filler portion of the polymer-modified asphalt coating; and
asphalt; and
a strip of nail zone reinforcement material adhered to the polymer-modified asphalt coating, the strip of nail zone reinforcement material having a width of 0.5 inches to 2.0 inches and a length that is greater than the width and runs in a machine direction of the shingle,
wherein the roofing shingle meets or surpasses the UL2218 Class 3 impact resistance standard, wherein the roofing shingle is free from an integrated polymeric backing that imparts impact resistance to the roofing shingle, and
wherein a cutting force required to cut the shingle through the nail zone reinforcement material is less than a cutting force required to cut through a nail zone reinforcement material area of an otherwise identical shingle having the same nail zone reinforcement material and an oxidized asphalt excluding the polymer additive.
