About Sullivan's Island.
Sullivan's Island has about 1,900 year-round residents on a 3-mile-long barrier island with deep historical roots — Fort Moultrie, beach cottages dating to the late 1800s, and a tight-knit community that's actively protective of the island's architectural character.
Roofs in Sullivan's Island.
Sullivan's Island has the oldest housing stock of any island in our service area. Historic cottages — many on the Town's historic inventory — sit alongside mid-century beach builds and recent custom homes. Slate, standing-seam metal, and high-quality cedar shake all appear with regularity. Architectural shingle is used selectively, primarily on newer or modestly-scaled builds.
Climate & conditions.
Same maximum coastal exposure as Isle of Palms — salt, wind, sun, and tropical storm impacts. Hurricane wind tends to funnel between island structures in ways that load corners and ridge lines aggressively. We install to a 140 mph minimum and step to 150 on any directly oceanfront or open-elevation home.
What sets Sullivan's Island apart.
The Town of Sullivan's Island operates an active Design Review Board with detailed guidelines on roof materials, profiles, and visible changes. Approval is required for any change visible from the public right-of-way. We prepare full submittal packages — drawings, samples, photos, neighbor-context studies — and have a working knowledge of what the board approves and what it pushes back on.
Sullivan's Island customers ask.
- What does the Sullivan's Island Design Review Board look at?
- Roof material, profile, color, panel dimensions, ridge and eave details — basically every visible roof characteristic. For any change visible from a public street, the board reviews the submittal against the town's architectural guidelines. We prepare packages with material samples, photo context of neighboring roofs, and elevation drawings as needed.
- Can you do slate replacement or repair on a historic cottage?
- Yes. We source slate through specialty Lowcountry suppliers, replace failed slate units, and handle full slate re-roofs when the historic character of the home warrants it. Slate is expensive and the labor specialized, but on the right Sullivan's Island home it's the correct material — and it will outlast everyone currently alive.
- Standing-seam metal on a Sullivan's Island home — is that approvable?
- Frequently yes, depending on the home's architectural character and the proposed color and profile. The board approves standing-seam where it's appropriate to the building tradition and reads correctly in the neighborhood context. We've prepared successful submittals for copper, aluminum, and galvalume standing-seam on a range of property types.
- How long does Design Review approval take?
- Typical timeline is 4–6 weeks from submission, including any back-and-forth on details. We submit the package, attend the board meeting on the homeowner's behalf, and answer questions. Once approved, we pull the building permit and schedule.
- Do you work on Front Beach and oceanfront properties?
- Yes. Oceanfront Sullivan's Island work involves coordination with the Town, OCRM, and often the homeowner's architect or engineer. We've worked Front Beach and the Atlantic Avenue back-beach corridor — we're happy to walk through the regulatory path before quoting.
