What Moves the Final Number on a McHenry County Roof Replacement
1. Tear-off vs overlay ($1.50 – $3.00 per sq ft added if tearing off)
Illinois code allows a maximum of 2 layers of shingles. If you already have 2 layers, both come off. Even with 1 layer, IHC recommends tear-off so we can inspect and replace any rotted sheathing. Homes in Woodstock, Harvard, and Marengo built pre-1970 often have decking damage from decades of ice dams.
2. Decking replacement ($75 – $100 per 4×8 sheet)
Once the old shingles come off, plywood decking underneath might be rotted, warped, or soft. A typical roof might need 5 to 15 sheets replaced. Pre-1960 homes in Harvard and original-grid Woodstock can need 30 – 40% more decking work — sometimes 40 sheets at $85 each.
3. Flashings ($1,500 – $3,000 for complex rooflines)
Every pipe vent, chimney, skylight, and wall junction needs new flashing. A simple ranch with one pipe boot is minimal cost. A two-story colonial with a chimney, three skylights, and a dormer adds $1,500 – $3,000 to the flashing line. Homes in Barrington and Lake Zurich tend to have more complex rooflines than McHenry County ranches.
4. Permits (every McHenry County municipality requires one)
Crystal Lake charges ~$125 (call (815) 356-3605). Harvard’s office is at 201 W Diggins St. Most cities are $75 – $200. The Illinois Roofing Contractor License (#104.015093 for IHC) is required to pull the permit — DIY is only allowed on your own primary residence. IHC handles all permits — you never go to city hall.
5. Insurance vs out-of-pocket pricing
Insurance-claim roof replacements use Xactimate pricing (insurance industry standard). Retail/out-of-pocket pricing is usually 10 – 20% lower because there’s no claim processing overhead. If your roof has storm damage from the August 2025 or April 2026 hail events, get a free inspection — many adjusters miss documentation that swings the claim.
McHenry County Roof Replacement — Frequently Asked Questions
How much does an asphalt roof cost in McHenry County?
In 2026, asphalt shingle roofs in McHenry County run $5.50–$11 per square foot installed. A standard 2,000 sq ft home with CertainTeed Landmark architectural shingles costs $12,000–$22,000 fully installed including tear-off, underlayment, flashings, and disposal.
How long does a roof replacement take in McHenry County?
A typical 2,000 sq ft McHenry County home takes 3–5 working days for an asphalt re-roof, 5–7 for synthetic or composite, and 7–10 for standing-seam metal. Weather delays add 1–3 days during spring/fall rain.
Do I need a permit for a roof replacement in McHenry County?
Yes — every McHenry County municipality requires a roofing permit. Crystal Lake’s permit fee is ~$125 (building department: (815) 356-3605). Other cities range $75–$200. Only Illinois-licensed roofing contractors (License #104.xxxxxx) can pull the permit; DIY is allowed only on your own primary residence.
Can I have a new roof installed over my existing roof?
Illinois code allows a maximum of 2 shingle layers. If you already have 2 layers, both come off. Even with 1 layer, IHC recommends tear-off so we can inspect and replace any rotted plywood sheathing — common on McHenry County homes pre-1970 from decades of ice dam damage. Tear-off adds $1.50–$3.00 per square foot.
My roof was damaged by the August 2025 or April 2026 hail storm — will insurance cover replacement?
Probably, if damage is documented within your policy’s filing window (typically 1 year from date of loss) and shows functional damage rather than cosmetic only. Adjusters often deny first claims — a re-inspection with a contractor present succeeds about 60% of the time. IHC’s sister company, IHC Public Adjusters (separately licensed under 215 ILCS 5/1575), can help reopen denied claims.
What’s the difference between a CertainTeed ShingleMaster and a regular roofing contractor?
A ShingleMaster is a CertainTeed-credentialed contractor. When a ShingleMaster installs CertainTeed Landmark shingles, the SureStart PLUS warranty covers material AND labor for 50 years, non-prorated. The same shingle installed by a non-certified contractor only gets material-only coverage. IHC is a credentialed CertainTeed ShingleMaster.
How long do asphalt roofs typically last in northern Illinois weather?
CertainTeed Landmark architectural shingles last 30–50 years in McHenry County. 3-tab shingles last 15–20 in our freeze-thaw climate. The biggest lifespan-killer here isn’t UV exposure — it’s ice damming, which a properly insulated and ventilated attic prevents.
