How to verify a South Carolina roofing contractor's license
South Carolina requires roofing contractors to hold a license issued by the Department of Labor, Licensing and Regulation (DLLR). You can search the DLLR's online contractor database to confirm that Cornerstone Construction—or any roofing company you are considering—holds a current, active license and has no unresolved complaints on file.
The DLLR database also shows whether a contractor has had disciplinary action taken against them. A clean record does not may provide quality work, but an expired license or a history of complaints is a red flag. Take the time to run this check before you call for an estimate.
What to ask a roofing contractor before you hire them
When you contact Cornerstone Construction or any roofing company, have a list of questions ready. Ask how long they have been in business, whether they carry liability insurance and workers' compensation coverage, and whether they offer a warranty on their work. Request the names and phone numbers of recent customers you can contact directly.
Ask what materials they recommend for your roof and why. Different roofing materials—asphalt shingles, metal, tile, or flat roof systems—have different lifespans, costs, and maintenance needs. A contractor should be able to explain the trade-offs and not just push the most expensive option. Also ask whether they handle the permit process or whether you need to obtain permits yourself, and who is responsible for cleanup and debris removal when the job is done.
Getting and comparing written estimates
Never hire a roofing contractor based on a phone quote. Request a written estimate that includes the roofing material, the square footage of the roof, labor costs, the timeline, and the total price. The estimate should also state what is covered by warranty and for how long. A detailed estimate protects you because it gives you something to refer back to if there is a dispute about what was promised.
Contact at least two or three roofing contractors and ask each one for a written estimate. Comparing estimates side by side shows you whether one contractor is significantly cheaper than the others—which may mean lower quality—or whether pricing is roughly consistent. If one estimate is much higher, ask that contractor to explain why. Sometimes the difference reflects better materials or a longer warranty, and sometimes it reflects padding.
What should be in a roofing contract
Before any work begins, you and the contractor should sign a written contract. The contract should state the scope of work (what exactly is being replaced or repaired), the materials being used, the start date and expected completion date, the total cost, and the payment schedule. Many contractors ask for a deposit upfront, a payment when the work is halfway done, and a final payment when the job is complete. This is standard, but the percentages should be spelled out in the contract.
The contract should also address what happens if weather delays the work, who is responsible for obtaining permits, and what warranty covers the new roof. Ask whether the warranty is from the contractor, from the roofing material manufacturer, or both. A manufacturer's warranty typically covers defects in the material itself, while a contractor's warranty covers the quality of the installation. Both matter.
Red flags to watch for when hiring a roofer
Be cautious of any contractor who asks for full payment upfront before work begins. Legitimate contractors understand that homeowners want to see progress before they pay in full. Also avoid contractors who pressure you to decide immediately or who offer a discount if you sign today. High-pressure sales tactics are common in roofing, and they are a sign to slow down and get another estimate.
If a contractor cannot or will not provide references, or if their license check shows complaints or disciplinary action, move on to someone else. Similarly, if a contractor shows up without a truck, tools, or insurance paperwork, or if they seem unfamiliar with South Carolina building codes, that is a reason to be skeptical. Roofing is a significant investment, and you deserve a contractor who is organized, transparent, and willing to answer your questions.
Frequently Asked Questions
How do I know if my roof needs repair or replacement?
A roof typically lasts 15 to 25 years depending on the material and climate. If your roof is leaking, has missing or curling shingles, or is sagging, it may need repair. If it is nearing the end of its lifespan or has widespread damage, replacement is usually more cost-effective than repeated repairs. A contractor can inspect your roof and recommend the best option.
What roofing materials are most common in South Carolina?
Asphalt shingles are the most affordable and widely used in South Carolina. Metal roofing is growing in popularity because it lasts longer and handles high winds and storms well. Tile and slate are more expensive but very durable. Your choice depends on your budget, the style of your home, and how long you plan to stay in the house.
Do I need a permit to replace my roof?
South Carolina requires a permit for most roof replacements. The contractor should handle the permit process, or they should clearly state in the estimate that you are responsible for obtaining it. Permits ensure the work meets building codes and protects you if something goes wrong. Never hire a contractor who suggests skipping the permit to save money.
What should I do if I am not satisfied with the roofing work?
Contact the contractor in writing and describe the problem. Most contractors will return to fix defects covered by their warranty. If the contractor refuses or is unresponsive, you can file a complaint with the South Carolina Department of Labor, Licensing and Regulation. Keep all contracts, estimates, and photos of the work for your records.
How much does a roof replacement cost in South Carolina?
Costs vary widely based on the size of your roof, the material you choose, and local labor rates. Asphalt shingle replacement is generally the least expensive option, while metal or tile is more costly. Get multiple written estimates so you understand the range for your specific home and situation.
