A small town on a high ridge between Four Holes Swamp and Cypress Swamp that began in 1831 as one of the first stations on the South Carolina Railroad, and it keeps a quiet, rural character.
Housing from this stretch in Ridgeville sits on plywood or OSB decking and was largely first roofed with three-tab shingles. Most are on their second covering by now. The things worth checking are the penetrations rather than the field: pipe boots from this era are the single most common leak we trace, because the rubber collar splits long before the shingles wear out. Ridge venting was inconsistent through these years, and OSB that has been damp for a season goes soft in a way plywood does not — you find it with your feet, not from the ground.
Ridgeville has 217 homes in the Census Bureau's count and a median year built of 1977. 11 of them (5%) went up before 1940 — 9th of 28 places on this site for pre-1940 share — and 66 (30%) in 2000 or later. The 1970s were the busiest decade, adding 99 of today's homes (46%). (Dorchester County as a whole: 2% before 1940.)
The Residential Rehabilitation Inspection Guide published by the U.S. Department of Housing and Urban Development puts the service life of an asphalt shingle roof at about 20 years. On that yardstick the 151 homes in Ridgeville built before 2000 (70%) have outlived at least one roof, and 19% (41 homes) go back before 1970, two roof lives and more. The 62 homes from the 2000s are where first replacements come up now, while the 4 built since 2010 are mostly still on the roof they were built with.
71% of homes in Ridgeville are single-family detached houses (153) and 1% attached ones such as townhouses (2). 6 homes (3%) sit in two- to nine-unit buildings. The count also takes in 56 mobile homes, which are a different kind of roof job. 153 of 199 occupied homes (77%) are lived in by their owners. With houses like these, the jobs we expect most are first replacements on 2000s builder-grade shingles and hail checks on newer roofs that look fine from the driveway.

NOAA’s Storm Prediction Center logged no reports of hail 1 inch or larger within 5 miles of Ridgeville’s center from 2016 through 2025. That is a gap in the reports rather than proof that no hail fell: reports come from spotters and the public.
