Beyond the Shingles: 5 Dirty Secrets of 'Cheap' Roofing Estimates in Chicago

In the Windy City, we’re used to looking for a deal. But when it comes to your roof—the only thing protecting your family from Illinois’ brutal winters and summer hailstorms—"cheap" often ends up being the most expensive mistake you’ll ever make.

If you’ve received a quote that’s significantly lower than the others, here is what that contractor isn't telling you:

1. "We’re Reusing Your Old Flashing"

Flashing is the metal material used to direct water away from critical areas like chimneys and valleys. Cheap contractors often skip replacing it to save on labor and materials.

• The Illinois Reality: With our freeze-thaw cycles, old flashing becomes brittle. If it’s not replaced, your "new" roof will leak in its very first winter.

• 
  

2. "We’ll Cover Up Rotten Decking"

A professional estimate includes a per-sheet price for plywood replacement. A cheap estimate assumes everything is fine. If they find rot, they might simply "shingle over it" to keep their low-price promise.

• The Risk: Shingles need a solid base. Nailing into rotten wood means your roof could literally peel off during the next high-wind warning at O'Hare.

• 
  

3. "We Don't Carry Workers' Comp Insurance"

Insurance is one of the highest overhead costs for legitimate Illinois roofers. By hiring "Chuck with a truck" who lacks proper coverage, you lower the bid.

• The Risk: If a worker falls on your property in Illinois without the contractor having Workers' Comp, the legal and medical liability could fall directly on your homeowner's insurance.

• 
  

4. "We’re Mixing and Matching Systems"

To cut costs, some contractors buy "seconds" (slightly defective shingles) or use a high-quality shingle with a bottom-barrel underlayment and starter strip.

• The SEO Fact: Most major manufacturers like GAF or Owens Corning require a complete system (using their specific branded components) to honor their 30-year or Lifetime warranties. Mixing brands kills your warranty.

• 
  

5. "We Won't Be Around for the Warranty Call"

Price-cutting contractors usually have a lifespan of 2–3 years before they go out of business due to low margins.

• The Result: A "10-year labor warranty" is only as good as the company behind it. If they aren't around to pick up the phone when a leak happens in 2028, that paper is worthless.

The Homeowner’s Checklist: 5 Questions to Ask Before Comparing Roofing Estimates in Chicago

Don't just look at the bottom number. Ask these five questions to see if they are cutting corners:

1. On Flashing: "Will you provide a line item for new flashing for my chimney and valleys, or are you planning to reuse the old metal?"

2. On Decking: "What is your specific price per sheet if you discover rotten plywood during the tear-off?"

3. On Liability: "Can you provide a COI (Certificate of Insurance) showing active Workers' Compensation and General Liability for the state of Illinois?"

4. On Warranty: "Are you a 'Certified' or 'Master Elite' installer for the brand you are using? Does the warranty cover the entire system or just the shingles?"

5. On Stability: "How many local projects have you completed in Chicago in the last 24 months, and can I speak to two of those homeowners?"
