Roof Replacement

Replacing your roof isn't just about shingles. We install ice and water shield in the valleys and along eaves, synthetic underlayment across the whole deck, new drip edge on rake and eave, starter strip, and ridge vent. That's how a roof lasts 30 years in Illinois.

Roof repairs get worse when you ignore them. A $400 flashing repair turns into $4,000 of water damage inside the wall. Our Cornell crew can usually get there within 48 hours for non-emergency repairs.

Simple Process

How It Works

1

We Inspect First

Before we quote anything, we inspect everything. Shingles, flashing, pipe boots, ridge vent, soffit, gutters. You get a full written report with photos.

2

No-Surprise Quote

We price by the roofing square with all materials itemized. You'll see exactly what you're getting. Shingle brand, underlayment type, ventilation specs, flashing details.

3

Roof Goes On

Our crews average 8 years of experience each. They tear off the old roof, inspect the decking, replace any damaged boards, and install your new system from the deck up.

4

Final Walkthrough

We walk the property with you, show you the finished roof, answer any questions. Then we run the magnetic nail sweep and clean up every scrap of debris.

"Used Cornell Roofing & Maintenance for a leak repair over our bathroom. Turned out to be a cracked pipe boot — $425 fix. Honest guys, could have told me I needed a new roof but they didn't."

FAQ

Frequently Asked Questions

The shingles carry the manufacturer's warranty. Typically 30-50 years for architectural shingles. Our installation warranty covers any defects in our workmanship. If something goes wrong because of how we installed it, we fix it at no cost. Both warranties are in writing and we provide them at the final walkthrough.

Yes. One day is standard for most residential jobs. We start early, work efficiently, and finish before dark. If your roof is larger than 40 squares or has a complex layout, it might push to day two. Either way, we seal everything watertight before we leave each night.

Yes. We offer 12-month same-as-cash, low-interest plans up to 144 months, and no-money-down options through GreenSky and Hearth. Credit approval takes about 5 minutes. A new roof is a major expense. Financing lets you get it done now without draining your savings.

Poor ventilation causes premature aging. If your attic runs hot in summer and your shingles are curling at 15 years, bad ventilation is probably why. Missing shingles cause water intrusion and accelerate everything. We do a free inspection and give you a straight answer: repair, plan for replacement in 2-3 years, or replace now.

Call (877) 349-1553 immediately. While you wait, put containers under any drips and move furniture and electronics away from the affected area. Take photos of the damage for insurance. Our Cornell crew will tarp the leak source and schedule a permanent repair. Most emergency calls get same-day or next-day response.
