The stock
What South Chicago's housing is made of.
67.2% of South Chicago's homes predate 1980. 72.5% carry asphalt-shingle roofs, 75.2% are masonry-walled (not a siding market), and 79.0% have a full or partial basement. 79.7% are owner-occupied.
Flood exposure: 0 homes sit in a FEMA Special Flood Hazard Area, while 4,583 (29.0%) carry a First Street flood factor of 5+ — water risk beyond the mapped floodplain.
The read for contractors
The 12,500–13,000 homes at 25+ years with no roof permit on file are where South Chicago's replacement cycle is furthest along — that cohort, minus fresh permits, is the campaign surface.

Re-roof waves
South Chicago's permit history has a shape.
Roof permits in South Chicago cluster into waves — the county file shows the biggest recent years to the right. Homes that didn't replace during a wave are aging on the same clock as the neighbors that did.
The read for contractors
Campaign the non-replacers inside a past wave's footprint — demand that already proved itself once tends to prove itself again.
