Roofing for Hanahan homes: replacement, leaks and storm damage. In Hanahan, the 2021 IRC is in force and 0% of the 8,671 homes went up before 1940. Any permit the job needs is ours to pull.
Hanahan runs to about 10.5 square miles and roughly 21,452 people. It sits about 11 miles north of downtown Charleston. The community dates back to 1973. We cover ZIP code 29410.
No completed roof in Hanahan is logged in our job records yet.
Single-family houses have been the most common type built in every decade since the 1930s, with building booms in the 1950s, the 1970s and the early 2000s; Tanner Plantation is the newest large area of homes.
We work across Hanahan rather than one corner of it — Hanahan Proper, Otranto, Eagle Landing and Tanner Plantation included. Age and construction change between them, which is why we look before we quote.
A mostly residential city at the southern tip of Berkeley County, with the Goose Creek Reservoir in its middle and several neighborhoods backing onto tidal water that reaches the Cooper River and Charleston Harbor. It roughly doubled in size after incorporating in 1973 by annexing Otranto and Tanner Plantation, and part of the Naval Weapons Station lies inside the city.
From this stretch of building, houses in Hanahan sit on plywood or OSB, were first roofed in three-tab shingles, and are mostly on their second roof now. Trouble tends to be at the penetrations rather than across the field: the rubber collar on a pipe boot splits years before the shingles give out, and it is the leak we trace most often. Ridge vents were hit and miss in these decades, and OSB that stays damp for a season softens in a way plywood does not, something you feel underfoot rather than see from the yard.
Hanahan has 8,671 homes in the Census Bureau's count and a median year built of 1986. 13 of them (0%) went up before 1940 — one of the five lowest pre-1940 shares of the 28 places on this site — and 3,380 (39%) in 2000 or later. The 2000s were the busiest decade, adding 2,106 of today's homes (24%). That is below Berkeley County's 1%.
About 20 years is the usual service life of an asphalt shingle roof, by the figure in HUD's Residential Rehabilitation Inspection Guide. By that measure, 61% of Hanahan's homes — the 5,291 built before 2000 — are past their first roof, and the 2,310 built before 1970 (27%) are usually on a third covering or later. The 2,106 homes from the 2000s are where first replacements come up now, while the 1,274 built since 2010 are mostly still on the roof they were built with. At that age it pays to know whether the last roof was torn off or laid over the one before it, because a second layer hides the deck.
By building type: 6,111 detached houses (70%), 250 attached (3%). 1,048 homes (12%) sit in two- to nine-unit buildings and 806 (9%) in buildings of ten units or more, where the roof is usually a landlord's or an association's decision. The count also takes in 456 mobile homes, which are a different kind of roof job. 68% of occupied homes are owner-occupied, 32% rented. On a housing mix like this, the likely work is first replacements on 2000s builder-grade shingles, flat and low-slope sections, which turn up more on attached and multi-unit buildings and hail checks on newer roofs that look fine from the driveway.

Between 2016 and 2025 there were 8 reports of 1-inch-plus hail within 5 miles of Hanahan’s center in the records of NOAA’s Storm Prediction Center, on 5 separate days. None was 1.75 inches or larger. The largest, 1.25 inches, came on July 19, 2017, about 0.1 miles southeast of the center. The most recent was 1 inch on July 14, 2024. A report needs someone to see the hail and send it in, so the count is a floor, not a full tally.
| Latest reports | Size | From center |
|---|---|---|
| July 14, 2024 | 1 inch | 2.9 mi S |
| May 9, 2024 | 1 inch | 3.8 mi NW |
| August 19, 2020 | 1 inch | 1.3 mi SW |
| July 19, 2017 | 1.25 inches | 0.8 mi S |
| July 19, 2017 | 1 inch | 2.3 mi S |
Hail damage rarely shows from the ground; a storm inspection photographs each slope so you know either way.
