Replacement demand, competitive density and housing stock for siding & exterior in Johnstown, PA, on the same basis as every other US metro. Every figure is computed from current Census, BLS and NOAA data and traceable to its source.
How much siding & exterior work the Johnstown metro generates in a year, and what share of it a single branch or acquisition could realistically reach.
Computed from the component scores below — not written by hand, and not generated.
Johnstown, PA has housing old enough to be replacing on a short cycle, comparatively few contractors chasing each home and a climate that works the building envelope hard. That works out to 29,554 addressable homes and an effective replacement cycle of about 28 years, or $18M of siding & exterior a year.
The problem is little new construction and household economics that will stretch to fund this work. The arithmetic does not put this market ahead of others, and arithmetic is famously hard to charm.
Seven components, each a percentile against all 935 US metros. The opportunity score is their weighted average, tilted toward what siding & exterior specifically depends on.
The interactive market file adds the full component breakdown, the inputs behind every figure, side-by-side comparison with other metros, and a re-pricing against your own ticket and installed capacity.
Substitute your ticket and installed capacity and the file recalculates: what you could deliver here, how your pricing lands against local incomes, and what would have to be true for the case to hold. Open access, no account, and the result is a link you can put in a memo.

Johnstown scores 51.7 out of 100 for siding & exterior, which ranks it 443 of 935 US metro areas. Johnstown, PA has housing old enough to be replacing on a short cycle, comparatively few contractors chasing each home and a climate that works the building envelope hard.
There is no metro-level count of siding & exterior firms specifically — the Bureau of Labor Statistics publishes establishments at the trade-group level. For the Johnstown, PA metro that is 143 specialty-trade contracting establishments (NAICS 238, covering roofing, siding, windows, gutters and the other exterior trades). That works out to 295.2 owner-occupied homes per contractor — the higher that number, the less crowded the market.
The average home in the Johnstown, PA metro is about 63.3 years old, and 80% of homes predate 1980. The median year of construction is 1956 — that figure and the average age are two different statistics and will not line up exactly, because the average is a weighted mean across every construction-year band while the median is only the midpoint. Housing age is the single strongest driver of siding & exterior replacement demand, because roofs, siding and windows are replaced on a cycle rather than bought on impulse.
Public sources only: the US Census Bureau's American Community Survey and Building Permits Survey for housing and households, the Bureau of Labor Statistics' Quarterly Census of Employment and Wages for contractor counts, and NOAA Storm Events and Climate Normals for hail and weather exposure. Market sizing applies published replacement cycles and average ticket prices to that stock — it is a model, not a measurement, and every assumption is visible inside the interactive report.

Figures reflect the most recent published vintage of each source as of 2026-08-13. Market sizing is a model, not a measurement: it applies replacement cycles and average ticket prices to the housing stock. Service areas are whole metros, so a single branch serving a drive-time radius will address less than the totals shown.
