Counts are Census estimates of housing units by year built (table B25034). If a roof had never been replaced, it would be 3 to 6 years old on a house from the 2020s, 17 to 26 on one from the 2000s, 37 to 46 on one from the 1980s and 87 or more on one from before 1940. Most older houses have had at least one replacement, and the Census does not record when.

What the numbers say about ZIP 99203

ZIP 99203 has 9,742 housing units: 9,375 (96.2%) were built before 2000, 181 (1.9%) in 2010 or later, and 3,289 (33.8%) before 1940, its largest era. The median year built is 1949 (Spokane: 1961), so 12 years older than the city.

Housing mix and money, from the same survey: 76.5% of occupied homes are owner-occupied; 86.2% of units are single-family houses; the median owner-occupied home is valued at $449,100, give or take $12,806; median household income is $95,532, give or take $10,029; the ZIP holds 9.5% of the housing units the Census counts in Spokane, 9,742 of them. These are survey estimates with margins of error, and for a small ZIP the margin can be wide.

Reading this for roofs, carefully: the Census records when a house was built, never when its roof was last replaced. If every roof were still the one installed with its house, 8,977 units (92.1%, built before 1990) would be past the 30-year top of the usual asphalt-shingle range, 398 (4.1%, the 1990s) would mostly sit past it, 186 (1.9%, the 2000s) would mostly be inside the 20 to 30 year window and 181 (1.9%, 2010 onward) would be younger than it. Most older roofs have been replaced, so treat these as the pool of houses where an old roof is possible, not as a count of old roofs.

Material ranges are general planning figures (the same ones as on our roof-age page), not warranties. Sun, storms, attic ventilation and installation quality move them. The decade shares assume homes were built evenly within each decade. This is not an inspection: a roofer on the roof decides.
