$81.53B a year in installed residential exterior wall systems demand, sized bottom-up across 935 metro and micropolitan areas (317.7M residents) and broken out by region, state and metro.
Built bottom-up from 935 metros: Census ACS housing stock (2023), Census Building Permits (2022–2024), BLS QCEW establishments (2020–2024), NOAA Storm Events (2016–2025). Scope: Residential siding and window & door replacement plus new single-family construction. Sheathing, insulation, house wrap and commercial curtain wall are not modeled and are not included.

What the national total is made of, and where it concentrates.
Census Building Permits Survey, 914 metros reporting every year. At the model's builder price this is $14.56B (2022), $13.76B (2023), $14.70B (2024) of new-construction exterior wall systems demand.
The drivers measured over time. There is no market-size growth rate here: the housing inputs are a single ACS vintage, so the total has no measured history.
BLS QCEW, NAICS 238170, annual average, 922 metros reporting every year — a metro suppressed in any year is left out of every year, so a disclosure gap is not read as firms closing. Siding and gutters share this code.
BLS QCEW, NAICS 238150, annual average, 922 metros reporting every year — a metro suppressed in any year is left out of every year, so a disclosure gap is not read as firms closing.
NOAA Storm Events, 858 metros, every year loaded. Hail pulls exterior wall systems replacement forward; it is the storm signal in the model.
Demand per specialty contractor establishment, and how US demand splits across the five saturation cohorts the metro reports use. Cohorts are quintiles of metros, so each holds about a fifth of them; the share of demand is what differs.
| Saturation cohort | Share of US demand | Median demand / firm | Metros |
|---|---|---|---|
| Land Grab | 27.0% | $7.80M | 183 |
| Wide Open | 40.1% | $4.59M | 182 |
| Balanced | 20.5% | $2.82M | 185 |
| Crowded | 7.6% | $1.36M | 183 |
| Knife Fight | 3.5% | $583.58K | 184 |
| Saturation cohort | Share of US demand | Median demand / firm | Metros |
|---|---|---|---|
| Land Grab | 16.0% | $8.66M | 183 |
| Wide Open | 31.0% | $5.10M | 183 |
| Balanced | 36.8% | $3.20M | 184 |

About $81.53B a year in installed value (labor and materials) across the 935 metro and micropolitan areas NextTerritory models, home to 317.7 million people. $66.79B of that is replacement on existing homes and $14.74B is new single-family construction, roughly 6,922,689 jobs a year. The figure is built bottom-up, metro by metro, from Census, BLS and NOAA data.
By annual demand: Texas $7.95B (9.8%); California $6.21B (7.6%); Florida $5.41B (6.6%); Illinois $3.74B (4.6%); Ohio $3.56B (4.4%). Together the top five carry 33.0% of national demand. State totals apportion each metro across its counties by single-family housing, so metros that cross a state line are split correctly.
New York, NY $3.36B; Chicago, IL $2.78B; Dallas, TX $2.41B; Houston, TX $1.95B; Los Angeles, CA $1.88B. The 25 largest metros account for 39.5% of US demand.
NextTerritory does not publish a growth rate for the market size itself: the housing-stock inputs come from a single American Community Survey vintage, so there is no measured history of the total to grow from. What is measured over time: single-family permits, the new-construction driver, moved +1.0% from 2022 to 2024 across 914 metros reporting every year; siding & exterior contractor establishments (NAICS 238170) moved +5.2% from 2020 to 2024 across 922 metros reporting every year; windows & doors contractor establishments (NAICS 238150) moved +8.3% from 2020 to 2024 across 922 metros reporting every year.
For each of the 935 metros: owner-occupied single-family homes that can buy the work, divided by the line's service life to give annual replacements, adjusted for housing age and hail exposure, priced at the model's average ticket — plus single-family permits priced at a builder rate. The national figure is the sum. The same model, at metro grain, powers every NextTerritory market report.
Most industry reports size manufacturer or material sales. This figure is installed value — what homeowners and builders pay contractors, labor and materials together — for residential work only, so it is larger and is not directly comparable. It is also reported by state and by metro, which national reports generally are not.
