Tear-Off to Final Inspection
Many suburban homes in West Ashley, James Island and Daniel Island wear architectural shingles, while many older peninsula houses sit under metal roofs with piazzas below. Either way, a full replacement takes off what's there instead of stacking new material on top, so the roofer can see the sheathing, swap out soft boards and build on a sound base.
Charleston has about 159,423 residents (2025 Census estimate), and 55.6% of homes are owner-occupied, so plenty of households will face this choice sooner or later.
Common Situations
- Shingles at the end of their run. Curled edges, bare patches and grit in the gutters often mean each repair buys less time than the last.
- Tired metal on an older house. Rust along seams and fasteners, or panels patched again and again, can point toward a full re-roof.
- Heat and damp wear. Long, humid summers feed algae streaks and age shingles early. Ask the roofer to check attic vents too.
- Salt air close to the water. Near the harbor and marsh, fasteners and flashing can corrode sooner. Ask which metals the roofer suggests for a home that close to salt water.
What Roof Replacement Typically Costs
These 2026 South Carolina statewide averages include tear-off. Coastal code items, salt-air materials and historic work such as copper or slate tend to push Charleston jobs toward the top or past it.

Timeline and Stages
- Your request. Fill out the form or call (843) 555-0174, and we send your details to one independent local roofer.
- The visit. The roofer looks over the roof and attic, measures, and talks through materials.
- A written estimate. Expect line items for tear-off, a sheathing allowance, underlayment, flashing, ventilation and cleanup.
- Permit and approvals. The City of Charleston offers a re-roofing permit, so ask your roofer to pull it. Its form asks for the roofer's SC LLR number and City business license number.
- Off with the old roof. The old covering is stripped, and rotted or soft sheathing boards are replaced before new material goes down.
- New roof and inspections. The City's form lists inspections such as wall and roof sheathing and strapping and tie-down, which the roofer books. Then get warranties in writing, with the manufacturer's one registered.
Why the Process Matters
Charleston's preservation rules reach back to 1931, when its zoning ordinance drew the nation's first defined historic district. Today the Board of Architectural Review's 2014 roofing policy covers the Old and Historic and Old City Districts, favoring repair of historic roofs wherever possible and replacement in kind once one is worn out. Standing-seam metal keeps hand-crimped seams, snap-lock panels are ruled out, and synthetic slate or tile is "generally not appropriate."
In either district, talk to City preservation staff before you change roof materials; no one can promise ahead of time what will be accepted. In unincorporated Charleston County, check with Charleston County Building Inspection Services.
- State registration. Look the roofer up on the SC Department of Labor, Licensing and Regulation (LLR) online lookup, and inside City limits ask for the City business license too.
- Coverage and paperwork. Ask for certificates of liability insurance and workers' comp, an itemized contract and written warranties. Skip anyone who wants cash only or the full price up front.
Quick Answers
Can new shingles go on over my old ones?
Some roofs can take a second layer, but covering old material hides the sheathing, so soft boards stay buried. That's why many Lowcountry homeowners choose a full tear-off. Ask the roofer which approach fits your roof and how it affects the warranty.
Who pulls the permit for a re-roof in the City of Charleston?
Usually the roofer, since the form asks for the roofer's LLR and City business license numbers. A homeowner may also apply for a single-family or duplex roofing permit. The Permit Center (843-577-5550) can answer questions about your address.
My house is on the peninsula. Can I switch from metal to shingles?
If the home sits in the Old and Historic or Old City District, the BAR policy leans toward keeping historic roofs and replacing worn ones in kind. Talk with City preservation staff before you plan a change of material, and do it before you sign a contract.
