Riverside Township, measured.
5,323 residential parcels on the official record. Median home built 1947. Every figure below is computed from the county assessor's file, county roof permits, FEMA + First Street flood layers — aggregate only, and never a claim about any specific property.
The stock
What Riverside's housing is made of.
95.9% of Riverside's homes predate 1980. 94.4% carry asphalt-shingle roofs, 55.0% are masonry-walled (not a siding market), and 94.9% have a full or partial basement. 91.8% are owner-occupied.
Flood exposure: 69 homes sit in a FEMA Special Flood Hazard Area, while 245 (4.6%) carry a First Street flood factor of 5+ — water risk beyond the mapped floodplain.
The 4,000–4,500 homes at 25+ years with no roof permit on file are where Riverside's replacement cycle is furthest along — that cohort, minus fresh permits, is the campaign surface.
Re-roof waves
Riverside's permit history has a shape.
Roof permits in Riverside 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.
Campaign the non-replacers inside a past wave's footprint — demand that already proved itself once tends to prove itself again.
| Year | Roof permits |
|---|---|
| 2022 | 259 |
| 2020 | 209 |
| 2021 | 206 |
