The stock
What Lyons's housing is made of.
76.8% of Lyons's homes predate 1980. 95.7% carry asphalt-shingle roofs, 36.1% are masonry-walled (not a siding market), and 80.9% have a full or partial basement. 90.3% are owner-occupied.
Flood exposure: 340 homes sit in a FEMA Special Flood Hazard Area, while 3,013 (9.9%) carry a First Street flood factor of 5+ — water risk beyond the mapped floodplain.
The read for contractors
The 23,500–24,000 homes at 25+ years with no roof permit on file are where Lyons's replacement cycle is furthest along — that cohort, minus fresh permits, is the campaign surface.

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