The stock
What Niles's housing is made of.
93.5% of Niles's homes predate 1980. 94.1% carry asphalt-shingle roofs, 64.7% are masonry-walled (not a siding market), and 94.8% have a full or partial basement. 90.5% are owner-occupied.
Flood exposure: 12 homes sit in a FEMA Special Flood Hazard Area, while 1,812 (5.6%) carry a First Street flood factor of 5+ — water risk beyond the mapped floodplain.
The read for contractors
The 31,000–31,500 homes at 25+ years with no roof permit on file are where Niles's replacement cycle is furthest along — that cohort, minus fresh permits, is the campaign surface.

Re-roof waves
Niles's permit history has a shape.
Roof permits in Niles 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.
