What Each Material Costs
The figures below are statewide South Carolina averages for 2026, and each one already includes tearing off the old roof. We found no source that publishes a Charleston-only number. Coastal code items, metals and fasteners picked to handle salt air, and historic work such as slate, copper, terne or hand-crimped seams tend to push Charleston jobs toward the top of these ranges, and sometimes past it.
| Cost row | Figure | Source (year) |
|---|---|---|
| South Carolina 3-tab shingles, per sq ft | about $4.70 | RoofObservations, 2026 |
| South Carolina architectural shingles, per sq ft | about $5.15 | RoofObservations, 2026 |
| South Carolina premium shingles, per sq ft | about $6.40 | RoofObservations, 2026 |
| South Carolina exposed-fastener metal, per sq ft | about $6.90 | RoofObservations, 2026 |
| South Carolina standing-seam metal, per sq ft | about $10.65–$14.25 | RoofObservations, 2026 |
Each figure is per square foot of roof surface, which runs larger than the floor plan once pitch and overhangs are counted. As a quick example, a roof surface of about 2,000 square feet in architectural shingles works out near $10,300 at the $5.15 average. That is a planning figure for your budget, never a quote.
To run the same math on your own home size, stories and roof steepness, open the roof cost calculator; it takes four quick answers.
Pitch, Layers and Size
Charleston homes vary a great deal. The Census puts the city's median owner-occupied home value at $509,700, yet a pricey house can sit under a simple roof and a modest one under a complicated roof. The roof itself sets the bill, and these are the things that move it most.
- Roof surface area. Size drives most of the total. A two-story house often has less roof than a one-story house with the same living space, because the roof only covers the footprint.
- Steepness and shape. Steep pitches, dormers, valleys and many separate roof planes slow the work and call for more safety gear, so these jobs tend to land in the upper half of each range.
- Old layers and decking. Extra layers to strip, or soft wood sheathing found once the old roof is off, mean more labor and lumber. The City's permit form even asks whether sheathing is part of the job.
- Salt air near the water. On the peninsula, Daniel Island, James Island and other spots close to the harbor or marsh, salt can speed rust on fasteners and flashing. Ask your roofer which fasteners and metals they plan to use there, and why.
- Historic districts. In the Old and Historic and Old City Districts, the City's 2014 roofing policy favors repair and replacing a worn-out historic roof in kind. Slate, copper and terne cost more. Talk to City preservation staff before you change materials.
- The permit. The City of Charleston has a re-roofing permit, and your roofer usually pulls it, so it may appear as its own line on the estimate. Towns and unincorporated county areas run their own permit offices.
- HOA rules. Many neighborhoods in West Ashley, James Island and Daniel Island set rules on roof color or material. A required color or a premium product line can change the price.
What a Written Estimate Includes
A good estimate breaks the job into parts, so you can compare two roofers line by line instead of judging by the bottom number alone. Ask that each of these appears in writing.
- Tear-off and disposal. How many layers come off, and who hauls the debris away.
- Decking repairs. A price per sheet for rotted sheathing, since nobody can see the deck until the old roof is removed.
- Materials by name. The product line, color and wind rating for shingles, or the panel style and coating for metal.
- Underlayment, flashing and vents. What goes under the new roof, and how chimneys, walls, piazza roofs and pipe openings will be sealed.
- Permit and inspections. Who applies for the permit and who books each inspection the City or your town requires.
- Warranties. The manufacturer warranty and the roofer's labor warranty, both written down, plus who registers the manufacturer warranty.
- Payment terms. When each payment is due. Be wary of cash-only terms or a demand for the whole price before work starts.
Before you sign anything, check the roofer's name on the SC Department of Labor, Licensing and Regulation (LLR) online lookup. Inside city limits, the City permit form also asks for the roofer's City business license number, so it's fair to ask for both. The South Carolina roofing rules page covers the rest.
Deductibles, Explained
When wind or a fallen limb, rather than plain age, ends a roof's life, your homeowners policy may cover part of the cost. Your deductible is still yours to pay. South Carolina law forbids a contractor from paying, waiving or rebating it, or promising to, so any offer to "take care of" your deductible is against state law.
Coastal policies may carry a separate hurricane or wind deductible on top of the usual one, so check your policy before you build a budget around a number. Some insurers give credit for wind-rated roofs or FORTIFIED-style construction. Each company sets its own terms, so ask yours what it offers before you choose materials.
The roofer's part is to document what the storm did and price the fix in writing. The claim itself stays between you and your insurance company. Roofers in South Carolina may not negotiate it on your behalf, and this site does not touch claims at all. More on storm roofs sits on the storm damage page.
