A new roof in South Carolina typically costs $6,000-$30,000, with many asphalt-shingle replacements landing near $12,000. Roof size, shingle grade, pitch, tear-off needs, and local labor rates drive the estimate; metal and specialty roofs often cost substantially more.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Asphalt shingle replacement | $6,000 | $12,000 | $20,000 | Common residential reroof |
| Installed asphalt roofing | $4.50/sq ft | $6.50/sq ft | $9/sq ft | Roof surface, not home floor area |
| Standing-seam metal roof | $12,000 | $22,000 | $40,000+ | Higher-grade metal systems can exceed this |
| Repair instead of replacement | $300 | $900 | $2,500 | Localized shingle or flashing work |
What South Carolina homeowners pay for a shingle roof
For a typical 1,700-2,200-square-foot roof with standard architectural asphalt shingles, a complete replacement commonly runs $8,000-$16,000. A smaller, simple roof may cost $6,000-$9,000, while a large or complex roof can reach $20,000 or more. A roofing square equals 100 square feet, so installed pricing of about $450-$900 per square is another way to compare bids.
Most ordinary asphalt reroofs fall around $5-$8 per roof square foot with tear-off and installation included. These are planning ranges, not fixed statewide rates; steep pitches, premium shingles, and hidden deck damage can move the total upward.
Assumptions: asphalt shingles, standard underlayment, one existing layer, normal access, and no major structural repairs.
How shingles, tear-off, and labor shape the quote
A written estimate should separate roof covering from removal and installation work. The following ranges are typical for a 2,000-square-foot roof and may vary with roof geometry and material selection.
| Quote item | Low | Average | High | What changes the charge |
|---|---|---|---|---|
| Shingles and underlayment | $2,500 | $4,000 | $6,000 | Brand, shingle grade, and coverage |
| Roofing labor | $2,500 | $4,000 | $6,500 | Pitch, access, crew time |
| Tear-off and disposal | $700 | $1,200 | $2,000 | Existing layers and landfill fees |
| Flashing, vents, drip edge | $400 | $900 | $1,800 | Chimneys, valleys, and upgrades |
| Deck repairs and contingency | $0 | $600 | $2,500 | Rot discovered after shingles come off |
Roofing labor may represent roughly $2,500-$6,500 on this example; crew size and access affect the hours, while estimates usually price the whole job rather than bill hourly.
Roof area, pitch, and material grade change the price
Roofers price the measured roof surface, not the home’s listed living area. A 1,500-square-foot house may have a 1,800-square-foot roof after accounting for overhangs and slope. Each additional 100 square feet can add about $450-$900 for asphalt, depending on the work included.
Pitch and complexity can raise installation costs even when roof area stays the same. A roof steeper than 6:12, multiple valleys, dormers, or difficult access may add 10%-30% to labor. Premium impact-rated or designer asphalt shingles can add roughly $1-$3 per square foot over basic options; metal commonly costs $12-$25 per square foot installed.
South Carolina’s wind, heavy rain, and coastal exposure make fastening details and flashing important. Homes near the coast may need corrosion-resistant components or higher-wind-rated products, adding several hundred dollars or more depending on the system.
Three roof sizes show realistic replacement budgets
These examples assume asphalt shingles, removal of one existing layer, standard flashing, and no extensive deck replacement. Roof area is measured along the slope.
| Roof scenario | Area and scope | Estimated total | Approximate rate |
|---|---|---|---|
| Small, simple roof | 1,200 sq ft, 2-person crew, about 16-22 labor hours | $6,000-$9,000 | $5-$7.50/sq ft |
| Typical family home | 2,000 sq ft, 3-person crew, about 24-36 labor hours | $9,000-$16,000 | $4.50-$8/sq ft |
| Large, complex roof | 3,000 sq ft, steep sections, about 40-60 labor hours | $16,000-$27,000 | $5.35-$9/sq ft |
Charleston and coastal bids can exceed inland rates
Roofing prices differ across the state because wages, disposal charges, access, and demand are local. Coastal Charleston and resort areas may run about 5%-15% above a comparable inland quote, especially when wind-rated materials or corrosion-resistant details are specified. Columbia, Greenville, and other inland markets often track closer to the statewide middle, while remote rural projects can incur travel or delivery charges.
Compare bids for the same roof area, shingle specification, tear-off layers, and flashing scope. A lower coastal quote may omit upgrades required by the site or local code, so confirm product ratings and installation details rather than comparing totals alone.
Removal, repairs, and storm damage add separate charges
Removing one layer of shingles typically costs around $0.50-$1 per square foot, including disposal; a second layer may add about $0.50-$1 per square foot. Replacing damaged roof decking often costs $75-$150 per sheet installed, depending on thickness and access. New flashing around a chimney or skylight may add $300-$1,000 or more.
Storm-related work can require temporary tarping, moisture checks, or interior repairs that are not part of a standard reroof. Ask whether the quote includes haul-away, magnetic nail cleanup, permit fees, and protection for landscaping. Insurance payment depends on policy terms and documented damage, not simply the age of the roof.
How long a South Carolina reroof takes
A straightforward asphalt-shingle replacement on an average home usually takes one to three working days with a crew of three to five roofers. A steep roof, multiple layers, rain delays, or extensive decking repairs can extend the schedule. Labor is often bundled into the total, but unusually difficult staging or limited access can increase the bid.
Scheduling after a major storm may take longer and can increase temporary protection or urgent repair charges. Obtain a written start window, expected duration, cleanup details, and payment schedule before signing.
Control the asphalt roof budget without cutting essential work
Keep the roof shape and scope straightforward where possible, and choose a standard architectural shingle instead of a designer line if its appearance and rating meet the home’s needs. Replacing gutters or skylights is not automatically necessary during reroofing; include them only when their condition justifies the added expense.
Compare at least three itemized quotes and verify that each covers the same tear-off, underlayment, ventilation, flashing, and disposal. Small repairs may be cheaper than replacement when damage is limited and the roof is otherwise sound, but recurring leaks or widespread shingle failure can make patching a poor long-term value. Avoid covering old shingles without confirming that local rules, roof weight, and manufacturer requirements allow it.
