The score is the same national scale for every metro, so it compares across state lines.
Saturation compares each metro's annual siding demand with its count of specialty contractor establishments (BLS QCEW). Across Washington's metros: 2 Land Grab; 5 Wide Open; 10 Balanced; 5 Crowded; 1 Knife Fight. Land Grab is the least crowded cohort nationally, Knife Fight the most.

Bottom-up, metro by metro: owner-occupied single-family homes divided by the line's service life, adjusted for housing age and hail exposure, priced at the model's average ticket, plus single-family permits at a builder price. Metros that cross a state line are split by single-family housing in each county. Rural counties outside a metro are not modeled.
