Duncan is a town in Spartanburg County with a 2020 census population of 4,041 and an elevation of about 853 feet. It lies between Greenville and Spartanburg, concentrated around the crossing of SC 290 and SC 292, with US 29 near its northern edge and Interstate 85 along its southern boundary. The Middle Tyger River runs through the north of town. For a homeowner searching for roofers in Duncan, SC, that corridor position is the point: it is a town close to both cities, with a roofing market that mixes older homes with newer builds.
Duncan received its charter in 1889 after the railway came through in 1873, so there is an old town core as well as newer subdivisions toward the interstate. The town is also home to the North American headquarters of several international manufacturers, including Staubli, the Rochling Group and the Draxlmaier Group. Older homes in the core are more likely to carry multiple roof layers, and newer subdivision roofs are the ones coming up for a first replacement. We have not sourced a median home age for Duncan, so that split is general guidance, not a statistic.
We are a referral service, not a roofer. We connect Duncan homeowners with a vetted, licensed roofing contractor who inspects for free and writes the price down before work starts.
Roof replacement in Duncan, SC
A roof replacement here is a full tear-off to bare decking, a decking inspection, new underlayment and flashing, and a new roof covering, priced in writing. On an older home in the town core the key line item is decking: our cost guide lists rotted decking at roughly $70 to $100 per sheet, and a second layer adds about $1,000 to $2,500 to the tear-off.
On a newer home the question is usually material. Most Upstate homeowners pick architectural asphalt. Those planning to stay for decades look at standing-seam metal; compare both in the metal roof cost guide.

Permits in Duncan and Spartanburg County
Spartanburg County Building Codes runs a residential permitting process with an online portal, and its published building permit application lists the department's office on North Church Street in Spartanburg. We have not confirmed whether the Town of Duncan or the county issues a reroof permit for a particular address, so ask the roofer to name the office on your estimate. The licensed roofer we refer files the right permit and meets the inspector. The Upstate permit guide explains the general city-versus-county rule.
What to check before you hire a Duncan roofer
Because Duncan sits between two metro areas, you will see trucks from roofers all over the Upstate. That is useful for competition and risky for accountability. Use our roofing contractor checklist to confirm the license, the insurance, the warranty and the written scope, and read how we vet our pros.
