Roof Replacement Issues Don't Wait
When your roof reaches the end of its lifespan — or suffers major storm damage — a repair won't cut it. Asphalt shingles in Illinois typically last 20–25 years under normal conditions, but hail, ice dams, and extreme temperature swings can cut that significantly. Missing granules, widespread cracking, sagging decking, dark streaking, and repeated leaks after the same area has been repaired are all signs replacement is overdue. Every month you delay, you risk water reaching the decking and framing — turning a $12,000 replacement into a $20,000+ structural repair.
How AJ Roofing Fixes It
AJ Roofing completes most residential replacements in a single day. Every job starts with a full tear-off down to the decking — no layovers, no shortcuts. We inspect and replace any rotted or damaged decking before anything goes on top. Our GAF Certified installation includes premium underlayment, proper ice-and-water shield at all eaves and valleys, and ridge ventilation — all the components that determine whether a roof lasts 20 years or 30. Shingle options range from GAF Timberline HDZ (our most popular — Class 4 impact, 25-year warranty) to designer and premium lines. We offer 0% financing for 12 months and longer-term options for qualified homeowners. Typical installed cost for SW Suburbs homes: $9,000–$18,000 depending on home size and materials.

COMMON QUESTIONS
Frequently Asked Questions
How long does a roof replacement actually take?
Most residential replacements — including full tear-off, decking inspection, underlayment, ice-and-water shield, and shingle installation — are completed in a single day. Homes over 3,500 sq ft or with complex hip/valley roof designs may take two days. You'll get an accurate timeline in your written estimate.
What is the best shingle for Illinois weather?
We recommend GAF Timberline HDZ as our standard for Illinois homes. It carries a Class 4 (the highest) hail impact rating, a lifetime limited warranty, and is eligible for the GAF WindProven unlimited wind warranty. It handles the 50°F temperature swings the SW Suburbs see in a single day, and many insurance companies offer premium discounts for Class 4 rated roofs. Designer and premium lines are also available — we'll walk you through the full comparison.
How much does a roof replacement cost in the SW Suburbs?
Typical installed cost for SW Suburbs homes runs $9,000–$18,000 depending on roof size, pitch complexity, and material selection. A 1,500 sq ft ranch with a standard pitch runs toward the lower end; a 2,500+ sq ft two-story with multiple hips and valleys runs toward the upper end. We provide free written estimates with line-item pricing — no vague ballparks.
Can I use my insurance to cover the replacement?
If the replacement is needed due to storm damage (hail, wind, falling tree), yes — this is typically fully covered minus your deductible. We inspect specifically for storm damage during free estimates and handle all insurance documentation and adjuster coordination at no extra charge. Many homeowners don't realize their roof qualifies until we inspect it.

WHAT AFFECTS PRICING
Factors That Influence Your Quote
Pitch & Complexity
Steeper or more complex rooflines require additional safety equipment, specialized techniques, and more time. A simple ranch is less expensive than a multi-gabled two-story of the same square footage.
Tear-Off vs. Layover
Complete removal of existing layers is required by Illinois code in most cases and gives new materials the solid, flat foundation they need. Layovers are cheaper upfront but void warranties and hide problems.
Decking Condition
After tear-off, we inspect every board for rot, soft spots, and water damage. Any damaged decking must be replaced before installation — this is non-negotiable for a roof that lasts.
Local Permits
Municipal permit costs vary across the SW Suburbs. We pull all required permits as part of every job — no shortcuts that could void your insurance or complicate a future home sale.
Attic Ventilation
Proper attic ventilation is required by both building code and shingle warranties. We assess your ventilation during the estimate — improper ventilation can cut shingle lifespan in half.
Material Selection
GAF Timberline HDZ (our standard) to designer and Class 4 impact-resistant lines — material choice is the biggest variable in your quote. We walk you through every option with real samples.
