The stock
What Bloom's housing is made of.
85.7% of Bloom's homes predate 1980. 97.8% carry asphalt-shingle roofs, 20.0% are masonry-walled (not a siding market), and 81.1% have a full or partial basement. 81.2% are owner-occupied.
Flood exposure: 196 homes sit in a FEMA Special Flood Hazard Area, while 1,745 (6.4%) carry a First Street flood factor of 5+ — water risk beyond the mapped floodplain.
The read for contractors
The 24,000–24,500 homes at 25+ years with no roof permit on file are where Bloom's replacement cycle is furthest along — that cohort, minus fresh permits, is the campaign surface.

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