Why Homeowners Choose Warner Roofing — The Most Respected & Trusted Name for 14+ Years
For more than a decade, Warner Roofing has earned a reputation as the most respected and trustworthy roofing company in the Rockford and Janesville regions. That trust was not built overnight — it comes from years of doing things the right way, holding the proper state licenses, maintaining full insurance, and standing behind every roof we install.
✔ Licensed in Both Illinois and Wisconsin
Very few contractors in our area hold professional roofing licenses in two states. Warner Roofing has maintained these licenses for 14+ years, proving consistent professionalism, compliance, and expertise. Our Illinois Unlimited Roofing License means we are authorized to work on any type of roof — residential, commercial, steep slope, or low slope — giving homeowners peace of mind that they are hiring a qualified, regulated, accountable roofing contractor.
✔ Fully Insured for Your Protection
Our company carries full general liability insurance, workers’ compensation insurance, and commercial coverage. This protects homeowners from all risk during a project. When an uninsured roofer makes a mistake, the homeowner ends up paying for it — but when you hire Warner, you are completely covered from start to finish.
✔ A Proven Record of Quality Workmanship
We back every full roof replacement with a 10-year workmanship warranty, something we could not legally or ethically offer without being fully licensed and insured. This warranty is a reflection of the confidence we have in our crews and our installation standards.
✔ Premium Materials from GAF & Owens Corning
High-quality shingles, underlayments, ventilation, and ice barriers matter. That’s why we partner with the best manufacturers in the roofing industry. Your home receives:
Lifetime limited shingle warranties
Wind protection warranties
Algae-resistant technology
Optional upgraded protection packages
When premium products meet licensed installers, homeowners get a roof built to last decades.
✔ A Long History of Community Trust
For 14 years, families across Rockford, Northern Illinois, Janesville, and Southern Wisconsin have relied on Warner Roofing because we’re dependable, professional, and transparent. We document damage with photos and video, we communicate clearly, and we stand behind our work long after the job is finished.
Warner Roofing isn’t the cheapest contractor — but we are the right contractor when your home and wallet need real protection.
