The Roofing
Knowledge Hub
This is the definitive technical resource for homeowners in Naperville, Lisle, Wheaton, and the surrounding Western Suburbs. From the nuances of Illinois Matching Laws to the unit-cost of Xactimate® pricing, we’ve documented the answers you need to protect your home's equity.
Does insurance pay for the whole roof if only one slope has hail?
In Illinois, the answer is governed by the "Line of Sight" Matching Rule. If your shingles are discontinued (which we verify via ITEL technical reporting), and the carrier cannot provide a "reasonable match" for the existing material, they are often legally obligated to replace the entire roof to maintain architectural uniformity. This is especially relevant in Naperville subdivisions like White Eagle or Green Trails where custom 1990s-era shingles are no longer manufactured.
How does the "Recoverable Depreciation" check work?
On an RCV (Replacement Cost Value) policy, the insurer splits your payment into two checks. The first is the Actual Cash Value (ACV)—the current value of your old roof. The second is the Recoverable Depreciation—the difference between the old roof's value and the cost of a new one. This second check is only released *after* we submit a final invoice and "Certificate of Completion" to the carrier. We handle all the paperwork to ensure your depreciation is released within 72 hours of project completion.
Will my premiums go up if I file a storm claim?
Under Illinois law, a weather-related claim is a "No-Fault" loss. While an insurance company cannot raise your individual rates for a single storm claim, they often raise rates for an entire **ZIP Code** after a major event like the 2020 Derecho. If your neighbors are filing claims and you aren't, you are essentially paying for their roofs through your rate increase while your own home remains damaged.

Is a Class 4 Impact-Resistant shingle worth the extra cost?
Absolutely. While Class 4 shingles (like GAF ArmorShield II) cost about 15–20% more, they trigger a permanent 20–28% premium discount with carriers like State Farm, Allstate, and Farmers. For a typical Naperville home, the upgrade pays for itself in premium savings in under 5 years—and protects your roof from stones up to 2 inches in diameter.
See the ROI Math Guide →What is an "Ice Dam" and how do I prevent them?
Ice dams occur when attic heat melts snow on your roof; the water refreezes at the cold eaves, creating a dam that forces water under your shingles. The fix isn't just shingles—it's Attic Ventilation. We install high-flow Ridge Vents and ensure your soffit intakes aren't blocked by insulation, aiming for a 1:150 ventilation ratio to equalize your roof temperature with the outside air.

We use the Equipter RB4000—a specialized mobile debris container that lifts up to the roofline to catch old shingles as they are removed. This prevents thousands of pounds of debris and nails from ever touching your flowerbeds, AC unit, or lawn. This is essential for the heavily landscaped properties common in Lisle's Arboretum neighborhoods.
