How to Find a Roofing Contractor Who Does Quality Work

What makes a roofing contractor reliable

A quality roofing contractor shows up on time, follows the timeline they gave you, cleans up after the job, and stands behind their work with a written warranty. They answer your questions directly instead of rushing you, give you a written estimate before starting, and carry liability insurance and workers' compensation. You can call their past customers and hear the same story from multiple people—not just the ones they hand you.

The difference between a contractor who cuts corners and one who doesn't often shows up months or years later, when a cheap roof starts leaking or a rushed job leaves gaps. A quality contractor uses materials rated for South Carolina's climate—hot, humid summers and occasional ice storms—and knows how those conditions affect shingles, flashing, and underlayment over time.

Price alone tells you almost nothing. The cheapest bid often means the contractor is cutting material costs, rushing the job, or both. The most expensive bid doesn't may provide quality either. What matters is whether the contractor can explain what they're doing, why it costs what it costs, and what happens if something goes wrong.

Key Takeaways

• A quality contractor provides a written estimate, carries insurance, and gives you references from recent jobs in your area.
• Check whether the contractor is licensed in South Carolina and whether the state licensing board has complaints filed against them.
• A warranty should cover both materials and workmanship, and the contractor should put it in writing before work begins.
• Ask how long the job will take, what happens if weather delays it, and whether they'll clean up debris when they're done.
• Call at least three past customers and ask whether the work was done on time, whether the price stayed the same, and whether they'd hire the contractor again.

How to check a contractor's background

Start by searching the South Carolina Department of Labor, Licensing and Regulation (SCDHEC) website for the contractor's license number. Not all roofers are required to be licensed in South Carolina, but many are, and the license database shows whether any complaints have been filed. A contractor with no license and no complaints isn't necessarily bad—but a contractor with a license and a clean record has already passed a basic check.

Search online for the contractor's name plus "reviews" and "complaints." Look at the Better Business Bureau (BBB) for South Carolina, which lists complaints and how the contractor responded. Read recent reviews on Google and Yelp, but remember that people who had a good experience often don't leave reviews—you're seeing a skewed sample. What matters more is whether complaints get resolved and whether the contractor responds to criticism.

Ask the contractor for at least three references from jobs completed in the last two years. Call them. Ask whether the work was finished on the promised date, whether the final bill matched the estimate, whether the contractor cleaned up, and whether they would hire the same contractor again. If a contractor won't give you references or the references won't call you back, that's a warning sign.

What to look for in a written estimate

A quality estimate breaks down the cost into materials, labor, and any other charges. It names the specific shingles or roofing material you're getting—not just "asphalt shingles" but the brand, weight, and color. It says how many squares (a square is 100 square feet) your roof is, what the labor cost per square is, and whether that includes removal of the old roof or just installation on top of it.

The estimate should list what's included and what's not. Does it cover new flashing around chimneys and vents? Does it include a new drip edge? Will they replace rotted wood underneath if they find it, or will that cost extra? Will they haul away the old roof, or will you need to arrange that? These details matter because they're where costs can balloon after the work starts.

A good estimate also says when the work will start and when it should be finished. It names the warranty—how long it covers materials, how long it covers workmanship, and what's actually covered. Some warranties cover only defects in materials; others cover labor too. The estimate should say whether the warranty transfers to the next owner if you sell your house.

Questions to ask before you hire

Ask whether the contractor carries general liability insurance and workers' compensation insurance. Request proof—a certificate of insurance, not just a verbal yes. If a worker gets hurt on your roof and the contractor isn't insured, you could be liable. If the contractor damages your gutters or siding and isn't insured, you're paying to fix it.

Ask what happens if the job takes longer than expected. Will the price change? What if weather delays it? What if they find rotted wood or other damage once they start? A contractor who says "I'll let you know before I do any extra work" is better than one who says "I'll just fix it and bill you."

Ask whether they'll pull a permit. In many South Carolina municipalities, roofing jobs require a permit and an inspection. A contractor who skips the permit might be cutting corners on quality or trying to avoid taxes. A permit also protects you—if something goes wrong, the inspection creates a record of what was supposed to happen.

Ask how they'll protect your property during the job. Will they cover your air conditioning unit? Will they lay tarps to catch nails and debris? Will they remove the old roof the same day or leave it sitting for weeks? These details affect how much mess ends up in your yard and gutters.

Red flags that suggest lower quality

A contractor who wants cash only and no receipt is a red flag. So is one who pressures you to decide today or says the price goes up tomorrow. A contractor who won't give you references or whose references don't return calls is telling you something. A contractor who shows up with no insurance paperwork or can't name the specific materials they'll use is cutting corners.

Beware of contractors who knock on your door after a storm and offer to file your insurance claim for you. Some of these are legitimate, but others inflate damage claims or pressure you into unnecessary work. If you want to file a claim, contact your insurance company directly and ask them to send an adjuster.

A contractor who guarantees they can fix a leak without inspecting the roof first probably can't. Leaks often come from places you can't see from the ground—under flashing, in valleys, or where the roof meets a wall. A quality contractor will inspect the roof, show you where the problem is, and explain why their fix will work.

Understanding warranties and what they cover

Most roofing materials come with a manufacturer's warranty that covers defects in the shingles themselves—splitting, curling, or loss of granules. This warranty is usually 20 to 30 years, but it often decreases over time. A 30-year warranty might cover 100 percent of replacement cost in year one, but only 50 percent by year 15. Read the fine print.

The contractor should also offer a workmanship warranty that covers their installation. This is separate from the material warranty and covers things like improper nailing, flashing that wasn't sealed right, or valleys that weren't installed correctly. A quality contractor typically offers five to ten years of workmanship warranty. Get this in writing before work starts.

Ask whether the warranty covers labor if something fails. Some warranties cover only the material cost to replace a failed shingle; you pay the labor to install it. Others cover both. Ask whether the warranty transfers if you sell your house—some do, some don't, and some transfer but with reduced coverage.

How to compare multiple bids fairly

Get at least three estimates. Make sure each one is for the same job—same materials, same scope of work, same timeline. If one estimate is half the price of the others, ask why. Is it a cheaper material? Is the contractor planning to leave the old roof in place instead of removing it? Is the warranty shorter? There's usually a reason.

Don't choose based on price alone. A contractor who's $2,000 cheaper might be using lower-grade shingles, skipping the underlayment, or planning to rush the job. Over 20 years, a $2,000 savings now might cost you $10,000 in repairs later. What matters is value—what you're getting for the price.

Compare the warranties side by side. Compare the timelines. Compare what's included in the cleanup. Compare the references and reviews. A contractor who costs a bit more but has better references, a longer warranty, and a reputation for finishing on time is usually the better choice.

Frequently Asked Questions

How do I know if a contractor is licensed in South Carolina?

Search the South Carolina Department of Labor, Licensing and Regulation website using the contractor's name or license number. Not all roofers require a license, but if one claims to be licensed, you can verify it there. The database also shows whether complaints have been filed and how they were resolved.

What should I do if the contractor finds damage I didn't know about?

Ask them to show you the damage and explain why it needs to be fixed. Get a separate written estimate for the extra work before they do it. If you're not sure whether it's necessary, you can ask another contractor for a second opinion. Don't let them start work on extras without your written approval and a price.

Can I negotiate the price after I get an estimate?

You can ask, but understand what you're negotiating. If a contractor lowers the price, ask what changes—are they using cheaper materials, cutting out part of the job, or just accepting lower profit? A contractor who drops the price by 20 percent without changing anything is either overcharging everyone else or planning to cut corners on your job.

What's the difference between a 20-year and 30-year shingle?

A 30-year shingle is thicker and heavier, with more asphalt and granules. It typically lasts longer and resists wind and weather better. The price difference is usually 10 to 20 percent. In South Carolina's heat and humidity, a heavier shingle often holds up better, but the manufacturer's warranty doesn't mean the shingle will actually last that long—it depends on climate, ventilation, and maintenance.

Should I get a permit for a roof replacement?

Many South Carolina municipalities require one. A permit means an inspector will check that the work meets code. It costs money and takes time, but it protects you—if something goes wrong, there's a record of what was supposed to happen. Ask your contractor whether a permit is required in your area and whether the cost is included in their estimate.
