Roofing for Mount Pleasant homes: replacement, leaks and storm damage. In Mount Pleasant, the 2021 IRC is in force and 1% of the 44,376 homes went up before 1940. Any permit the job needs is ours to pull.
Mount Pleasant runs to about 49.7 square miles and roughly 93,993 people. It sits about 4 miles northeast of downtown Charleston. The community dates back to 1837. We cover ZIP codes 29464, 29465, 29466 and 29429.
In the Old Village Historic District, the town's Historic District Preservation Commission has to approve before the roofing permit is issued. Replacing a historic roof with the same or a similar modern material can get a staff-level certificate, and routine repair with materials on the approved list needs no review. The approved roofing list runs from architectural shingles to standing-seam metal, copper, wood shakes, slate and 5-V crimp, and metal roofs are expected in historical colors such as tinner's red, black, silver-grey or patina green.
No completed roof in Mount Pleasant is logged in our job records yet.
The Old Village has 18th-, 19th- and early 20th-century houses in vernacular Georgian, Greek Revival and Gothic Revival styles; the earliest were simple cottages, with larger houses built once planters lived in town year-round.
We work across Mount Pleasant rather than one corner of it — Old Village, I'On, Scanlonville, Hobcaw Point and Snee Farm included. Age and construction change between them, which is why we look before we quote.
Mount Pleasant sits on the east side of Charleston Harbor and the tidal Wando River; it began as a summer resort, and its oldest neighborhood, the Old Village, has houses from the 1700s through the early 1900s. The town limits have since pushed about 24 miles northeast along U.S. 17, and the population roughly doubled between 1990 and 2000 in the growth that followed Hurricane Hugo in 1989.
Newer construction in Mount Pleasant generally has OSB decking, architectural shingles and a proper ridge vent, so the roofs themselves start in better shape. The catch is what the shingle was: a great deal of the building through the 2000s went on with builder-grade shingles carrying a nominal warranty far longer than their real service life, and those are reaching the end now. Hail is the other factor — a newer roof is not a hail-proof roof, and a bruised mat can look perfect from the driveway for two years and then start failing all at once. If yours has never been looked at after a storm, that is the reason to have it looked at.
The Census Bureau counts 44,376 homes in Mount Pleasant, with a median year built of 2000. 286 of them (1%) went up before 1940 — 18th of 28 places on this site for pre-1940 share — and 22,525 (51%) in 2000 or later. The 2010s were the busiest decade, adding 11,052 of today's homes (25%). Across Charleston County the pre-1940 share is 5%, so Mount Pleasant sits below it.
The rule of thumb in HUD's Residential Rehabilitation Inspection Guide is a service life of about 20 years for an asphalt shingle roof. On that yardstick the 21,851 homes in Mount Pleasant built before 2000 (49%) have outlived at least one roof, and the 3,181 built before 1970 (7%) are usually on a third covering or later. Homes from the 2000s (9,471 in Mount Pleasant) are reaching their first replacement, while the 13,054 built since 2010 are mostly still on the roof they were built with.
64% of homes in Mount Pleasant are single-family detached houses (28,236) and 12% attached ones such as townhouses (5,291). 3,011 homes (7%) sit in two- to nine-unit buildings and 7,560 (17%) 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 262 mobile homes, which are a different kind of roof job. 74% of occupied homes are owner-occupied, 26% 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.

From 2016 through 2025, NOAA’s Storm Prediction Center recorded 5 reports of hail of 1 inch or more within 5 miles of Mount Pleasant’s center, spread over 5 storm days. None was 1.75 inches or larger. The largest, 1 inch, came on May 17, 2023, about 4.3 miles southwest of the center. 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 |
|---|---|---|
| May 17, 2023 | 1 inch | 4.3 mi SW |
| May 9, 2023 | 1 inch | 2.2 mi N |
| June 15, 2021 | 1 inch | 3 mi NE |
| July 26, 2018 | 1 inch | 2.5 mi NE |
| July 19, 2017 | 1 inch | 3 mi N |
Hail damage rarely shows from the ground; a storm inspection photographs each slope so you know either way.
The Town's FAQ says a permit is needed to install a new roof on a house. The permit can be issued to the owner or to a contractor licensed to work in South Carolina. In the Old Village Historic District, approval from the Historic District Preservation Commission is needed before the permit can be issued. The Town's general rule (Ordinance 150.002) is that work valued at $1,000 or less in materials and labor does not need a permit unless an inspection is required. Work started without a permit can bring heavy fines and a ticket.
Mount Pleasant enforces the 2021 IRC. Since January 1, 2023 the Town has enforced the 2021 International codes with South Carolina amendments, and its residential plan checklists cite the 2021 IRC and 2009 IECC. The Town has announced that applications made after January 1, 2027 must be designed to the 2024 IRC and IBC.
The published number is 843-884-5184. The Town's staff directory lists Mike Taulbee as Deputy Director of Building Inspections. Its pages do not name a Building Official. The department page is here.
Wind design changes with location across greater Charleston: the published ultimate design wind speeds run 133–150 mph, and the building department can say which figure applies to a given address. See the roofing code guide for what it governs.

Older than most people guess: the Census puts 49% of Mount Pleasant's homes before 2000 and 7% before 1970, with a median year built of 2000 (2020–2024 estimates). A roof usually lasts about 20 years, so the deck and the layers get checked before any quote.
5 reports of 1-inch-plus hail fell within 5 miles of Mount Pleasant between 2016 and 2025, the biggest 1 inch on May 17, 2023 (NOAA Storm Prediction Center).
It can. Mount Pleasant has Mount Pleasant Historic District, Old Village Historic District and Phillips Community Historic District. Inside a designated district, changing a visible roof material or color can need preservation review before the permit is issued. Like-for-like replacement usually raises fewer questions, but we check before quoting.
Not yet: no completed roof in Mount Pleasant is in our job records, so this page shows no job count.
