Local housing stock
Building in Rochester clusters in the late 1970s: the median unit dates to 1978, with 69.8 percent finished before 1990. Frame and brick mill-era housing predominates with a median build year of 1978, mixed with later construction on the slopes above the river.
Climate & seasonal risk
October is the wettest month here at 5.14 inches, part of an annual 51.13 inches in the 1991–2020 normals from ROCHESTER, 0.3 miles off. A 51.13 inch annual total with an autumn maximum sets up the winter. Ground saturated in October freezes with that water in place, thaw cycles work joints wider through the cold months, and the spring release arrives at openings the winter enlarged.
Common moisture and mold problems in Rochester
- An autumn rainfall maximum saturating the ground immediately before the first hard freeze
- Repeated midwinter thaw cycles widening joints rather than one continuous freeze
- Mill-era masonry construction built without damp-proofing along the river corridor
- Ice damming at the eaves of older steep roofs during those same thaw cycles
