What Credentials Should a Roofing Contractor Have?

A roofing contractor in Illinois should have an active state roofing license and the required insurance. You should also look for relevant experience, references, and any manufacturer certifications that apply to the roofing materials being installed.

Some credentials are legal requirements that a roofing company must meet to operate. Others are qualifications that can help you evaluate the company's experience, training, and reputation.

Before hiring a roofer, it's worth understanding the differences.

How Do You Verify a Roofing Contractor's License in Illinois?

You can verify an Illinois roofing contractor's license through the Illinois Department of Financial and Professional Regulation (IDFPR), which maintains an official database of licensed roofing contractors.

Unlike some other types of contractors, roofing contractors in Illinois are required to hold a state-issued roofing license.

A contractor may tell you they're licensed or display a license number on their website, truck, or estimate. However, having a license number printed somewhere doesn't necessarily mean that license is currently valid.

Fortunately, you can check it yourself.

Step 1: Ask for the Contractor's Illinois Roofing License Number

Before agreeing to any roofing work, ask the contractor for their Illinois roofing license number and the legal name of the company that holds it.

Illinois roofing contractor license numbers generally begin with 104. If a contractor is unwilling to provide this information, that's a good reason to reconsider working with them.

Step 2: Look Up the License Through IDFPR

Visit the Illinois Department of Financial and Professional Regulation's roofing contractor page.

From there, search using the contractor's license number or business name.

When you find the company's record, check that:

• The license is listed as active.
• The license hasn't expired.
• The business name matches the company you're considering.
• The license classification is appropriate for the work being performed.

For most homeowners, this process only takes a few minutes. It's worth doing even if the contractor was recommended by someone you trust.

Step 3: Make Sure the License Belongs to the Company You're Hiring

Finding an active license is important, but you also need to make sure it belongs to the business that will be performing your roofing work.

The name on the license, estimate, and contract should be consistent or clearly connected. You should also ask whether the company uses subcontractors and who will be responsible for performing the roofing work.

In Illinois, roofing subcontractors must also meet applicable state licensing requirements.

How Can You Verify That a Roofer Is Properly Insured?

Ask the roofing contractor for a current certificate of insurance showing their liability coverage and workers' compensation coverage, when applicable. You can also contact the insurance provider to confirm the policies are active.

Insurance is one of the most important things to verify before allowing a contractor to work on your home. Even experienced roofing crews can encounter unexpected problems. Roofing involves working at heights, handling heavy materials, and moving equipment around your property, each of which carries its own risks.

Proper insurance helps protect against certain financial risks if something goes wrong during the project on your property. The two types of insurance roofing companies typically carry are general liability and workers' compensation insurance.

General Liability Insurance

General liability insurance can provide coverage for certain types of property damage or injuries connected to the contractor's work, subject to the terms of the policy.

For example, imagine roofing materials accidentally damage part of your siding or another area of your property during installation. A contractor's liability coverage may apply to that situation, depending on the circumstances and policy.

Illinois has minimum liability insurance requirements for licensed roofing contractors, but the amount and scope of coverage can vary from contractor to contractor.

Rather than simply asking, "Are you insured?" request documentation showing the company's current coverage if you’re unsure.

Workers' Compensation Insurance

Workers' compensation insurance generally provides benefits to covered employees who experience work-related injuries or illnesses.

If a roofer gets injured while working on your home, workers' compensation insurance can help cover their medical expenses and lost wages. Without appropriate coverage, an injury could lead to disputes over who is financially responsible, potentially involving the homeowner or their insurance company.

Because roofing is physically demanding work, it's important to understand whether the people working on your home are properly covered. Ask the contractor about their workers' compensation coverage and whether the crew consists of employees, subcontractors, or both.

The requirements can depend on the company's employment arrangements, so don't assume every roofing company has the same insurance obligations.

How Do You Know an Insurance Certificate Is Legitimate?

The best way to confirm a contractor's insurance is to review a current certificate of insurance and verify the coverage directly with the listed insurance agent or provider.

A certificate of insurance should identify the insured business, the types of coverage, the insurance company, and the policy dates. Check that the business name matches the contractor you're hiring and that the policies haven't expired.

If anything looks unclear, contact the insurance agent listed on the certificate and ask whether the coverage is currently in force. This extra step can help you avoid relying on outdated paperwork or verbal assurances.

Are Roofing Manufacturer Certifications Important?

Manufacturer certifications can indicate that a roofing contractor has completed certain training or met requirements established by a roofing material manufacturer, but they aren't a substitute for a state license or insurance.

You may have seen roofing companies advertise certifications from manufacturers such as GAF, Malarkey, or Owens Corning. These programs can involve product training, installation knowledge, business qualifications, or other requirements, depending on the manufacturer and certification level.

Oftentimes, these certifications affect which manufacturer-backed warranty options a contractor is eligible to offer. Manufacturer-certified contractors can typically offer stronger warranties than those who are not certified.

If a contractor advertises a manufacturer certification, ask what it means for your project. You can also check the manufacturer's official contractor directory, usually found on their websites, or contact the manufacturer to confirm the company's current status.

How Can You Verify a Roofing Contractor's Experience and Reputation?

You can evaluate a roofer's experience and reputation by reviewing recent customer feedback, asking for examples of similar projects, and checking references from homeowners they've worked with. A valid license and insurance are essential, but they don't tell you everything about how a company operates.

You also want to understand whether the contractor communicates clearly, performs the type of work you need, and follows through on their commitments.

Below we'll discuss a couple of ways to get a clearer picture.

Read Reviews Across Multiple Sources

Start by checking customer reviews on platforms like Google. Rather than focusing only on the overall star rating, pay attention to what homeowners say about their actual experiences.

Look for patterns involving communication, cleanliness, scheduling, unexpected costs, and how the company handled problems.

A company with excellent reviews may still have an occasional unhappy customer. What's more useful is understanding whether the same complaints appear repeatedly and how the contractor responds.

Ask About Similar Roofing Projects

A contractor who regularly installs asphalt shingle roofs may have different experience than one who specializes in metal roofing or complex repairs.

Ask whether the company has completed projects similar to yours, or if they have any examples of work done on homes with a similar design to yours.

Photos of completed work can be helpful, but if they can show you progress updates and explain how certain aspects of the previous project could apply to your home, that’s a good indication they’re thorough in their approach.

What Are the Warning Signs of an Unqualified Roofing Contractor?

A contractor who won't provide licensing or insurance information, pressures you to sign immediately, or refuses to explain the proposed work may not be someone you want working on your home.

Not every warning sign means a contractor is dishonest, but certain behaviors deserve a closer look.

Be cautious if a roofing company:

• Refuses to provide a license number or current insurance documentation.
• Uses a business name that doesn't match its licensing information without a clear explanation.
• Pressures you to sign a contract before you've had time to review it.
• Makes promises about repairs or insurance coverage that seem too good to be true.
• Provides a vague estimate that doesn't explain what work will be performed.
• Demands full payment before the roofing work begins.
• Avoids answering reasonable questions about materials, warranties, or the people performing the work.

These concerns can be especially important after a major storm, when homeowners may be approached by unfamiliar contractors offering immediate repairs. There's nothing wrong with a roofing company reaching out to homeowners after storm damage. However, you should still take the time to verify its credentials before signing anything.

The Illinois Attorney General's Office also provides consumer guidance about hiring contractors and avoiding potential scams.

Does Having the Right Credentials Guarantee a Good Roofing Contractor?

A valid license, proper insurance, and manufacturer certifications are important qualifications, but they don't guarantee that a contractor will perform quality work or provide a good customer experience.

You should think of credentials as the starting point rather than the final reason to hire someone. A contractor can meet the state's licensing requirements and still provide poor workmanship, recommend work you don't need, or fail to meet your expectations.

Because of this, it’s important to evaluate both the company's qualifications and how it treats you during the estimating process. You should feel comfortable asking questions and taking time to compare your options.

A trustworthy roofing contractor won't expect you to make a major decision based on a license number, certification badge, or sales presentation alone, and instead will help guide you through the process without taking control from you.

How Can You Feel Confident Before Hiring a Roofing Contractor?

The best way to protect yourself is to independently verify the contractor's license and insurance, review their experience, and make sure you understand the proposed work before signing a contract.

Checking a roofer's credentials doesn't have to be complicated, and it shouldn't require you to become an expert in roofing.

Start with the basics: confirm the company is properly licensed in Illinois, request proof of insurance, and verify any certifications they're advertising.

From there, pay attention to how the contractor communicates and whether their recommendations make sense for your home.
