What to Ask Before Hiring a Roofing Contractor in Illinois

Your roof is one of the most important and expensive components of your home. Hiring the wrong contractor to work on it can lead to poor workmanship, voided manufacturer warranties, insurance complications, and costs that far exceed what you would have paid a reputable company.

Illinois has no shortage of roofing contractors — and unfortunately, post-storm periods tend to attract out-of-town companies looking to do fast work and move on. Knowing what to ask before signing any contract is one of the best ways to protect yourself and your home.

Question 1: Are You Licensed and Insured in Illinois?

In Illinois, roofing contractors are required to be licensed. Always ask for the contractor’s roofing license number and verify it with the Illinois Department of Financial and Professional Regulation. Also confirm that the company carries both general liability insurance and workers’ compensation insurance. If a worker is injured on your property and the contractor lacks proper insurance, you could be held liable.

Red Line Roofing holds Illinois Roofing License No. 104.020077 and carries full liability and workers’ comp coverage.

Question 2: Are You a Local Company?

After major storms, Illinois communities are sometimes visited by ‘storm chasers’ — contractors from out of state who set up temporarily, do quick work, and disappear before any warranty issues can be addressed. A local, established company has a reputation to protect in your community and will be around if you have a concern after the job is done.

Ask where the company is headquartered and how long they’ve operated in the area. Check their Google reviews and look for patterns — both in what customers praise and in any concerns raised.

Question 3: What Materials Do You Use, and Are They Manufacturer-Certified?

The quality of roofing materials varies significantly. Ask what shingle brands the contractor uses and whether they are certified installers for those brands. Manufacturer certification matters because it often determines the warranty coverage available to you — certified contractors can offer extended manufacturer warranties that uncertified ones cannot.

At Red Line Roofing, we work with industry-leading brands and maintain the certifications that allow us to offer our clients the strongest warranty protections available.

Question 4: What Does Your Warranty Cover?

A roofing project should come with two types of warranty: a manufacturer’s warranty on the materials, and a workmanship warranty from the contractor. Ask specifically what each covers, how long each lasts, and what the process is for making a warranty claim. Be wary of contractors who are vague or dismissive about warranty details.

Question 5: Can You Provide a Detailed Written Estimate?

Any reputable roofing contractor should be able to provide a written estimate that details the scope of work, materials to be used, timeline, and total cost. Verbal estimates are not sufficient. A written estimate protects both parties and gives you something to compare if you’re getting multiple quotes.

Be cautious of estimates that are significantly lower than competitors — sometimes this reflects corners being cut on materials or labor.

Question 6: How Do You Handle Cleanup and Disposal?

Roof replacement generates significant debris — old shingles, nails, and underlayment. Ask how the contractor handles cleanup and disposal. Will they use protective coverings on your landscaping? Will they use a magnetic nail sweep to collect loose nails from your yard? A professional company should leave your property clean.

Question 7: Do You Have Experience with Insurance Claims?

If your roof replacement is connected to an insurance claim, ask whether the contractor has experience working with insurance companies. This doesn’t mean they act as your insurance representative — it means they understand how to document damage professionally, provide estimates in the format insurers require, and communicate effectively throughout the process.

Final Thoughts

Taking the time to ask these questions before hiring a roofing contractor takes less than 30 minutes — and can save you from a great deal of stress, expense, and disappointment. Don’t rush the decision. Your roof is worth getting right.
