When patching and repairs are no longer enough, Cornerstone Roofing Co. delivers complete roof replacement with premium materials built to handle Chicago's brutal freeze-thaw cycles, high winds, and heavy snow loads.
A roof replacement is one of the most significant investments you will make in your Chicago-area home. Unlike a simple repair that addresses isolated damage, a full replacement strips the existing roofing system down to the deck and installs an entirely new underlayment, flashing, ventilation, and surface material. For homes across Cook County, DuPage County, and the surrounding suburbs, this process is critical when aging shingles begin curling, granule loss accelerates, or multiple leaks indicate systemic failure rather than localized wear.
Cornerstone Roofing Co. has completed over 500 roof replacements throughout the greater Chicagoland area. Our crews understand that the Lake Michigan wind corridor, seasonal hail events, and temperature swings exceeding 100 degrees annually demand more than a cookie-cutter install. Every project begins with a 21-point structural inspection that evaluates decking integrity, attic ventilation ratios, and flashing condition before a single shingle is removed.
We hold GAF Master Elite certification, which places us in the top 2% of roofing contractors nationwide and allows us to offer the Golden Pledge limited warranty covering both materials and workmanship for up to 50 years. Whether your home is a classic Chicago bungalow in Lincoln Square, a colonial in Naperville, or a contemporary build in Schaumburg, our team tailors the replacement to your home's architectural style and structural requirements.
Financing is available for qualified homeowners, and we work directly with insurance carriers when storm damage triggers the need for a full replacement. Our project managers handle permit acquisition through the City of Chicago or your local municipality, so you can focus on choosing the color and style that best suits your home.
A certified inspector examines every square foot of your existing roof, attic space, and ventilation system. We document damage with photos and thermal imaging when necessary to identify hidden moisture intrusion.
You receive a transparent, line-item estimate covering tear-off, disposal, materials, labor, and permits. Our showroom lets you compare asphalt, metal, slate, and cedar options side by side.
We pull all required permits from the City of Chicago or your suburb's building department. Your project is scheduled with a confirmed start date and estimated completion window.
The old roofing system is removed entirely. Our crews inspect the decking for rot, delamination, or structural compromise and replace damaged sections before new material goes on.
Ice-and-water shield is applied at eaves, valleys, and penetrations per Illinois code. Synthetic underlayment, starter strips, field shingles, ridge ventilation, and flashing are installed to manufacturer specifications.
A project manager walks the completed roof with you, answers questions, and ensures your satisfaction. We register your manufacturer warranty the same day and provide a complete project file for your records.
