A full roof replacement near Highland Park is a structured project with defined steps, documented material requirements, permit requirements, and inspection checkpoints. Homeowners who understand what that process involves are better equipped to evaluate contractor proposals, hold crews accountable, and get the most from their insurance coverage.
This guide covers the complete replacement process from the initial inspection through the final permit closure, cost ranges by project type, what insurance covers and what it doesn’t, and what to verify before and after the work is done.

Replacement is the correct choice over repair in the following situations:
- The roof is 20 or more years old and showing widespread granule loss or shingle cracking across multiple slopes
- Two layers of shingles are already present — Illinois building code does not allow a third layer on most residential roofs
- The decking shows moisture damage across multiple sections — not isolated to one zone
- Storm damage has been assessed as a total replacement event by an insurance adjuster
- The cost of repairs needed over the next 3 to 5 years approaches or exceeds the replacement cost
- The homeowner is planning to list the property for sale within 3 to 5 years
A professional inspection determines which option applies to your specific roof condition. JSMM Inc provides free on-site inspections with a written report before any recommendation is made.

The Pre-Replacement Inspection
A roof replacement begins with a complete inspection — not a quote. The inspection covers:
Exterior Surface
All slopes are assessed for shingle condition, granule coverage, ridge and hip integrity, and visible structural deflection. Photographs are taken of every slope.
Attic Interior
Moisture readings are taken on decking, rafters, and insulation. Ventilation is evaluated — net free ventilation area is calculated against code minimums. Daylight visible through the deck is documented.
Decking Condition
Walking the roof surface identifies soft spots. Any decking damage found after tear-off is separately documented and quoted at a per-sheet rate that should be established before the contract is signed.
Flashings and Penetrations
All existing flashing is assessed for condition. On a full replacement, JSMM Inc replaces all flashings — reusing old flashing on a new roof system undermines the warranty and creates early leak points.
The inspection report is delivered in writing. No replacement estimate is prepared without completing all four inspection components.

The Roof Replacement Process — Step by Step
Step 1: Permit Filing
The City of Highland Park requires a building permit for full roof replacements. JSMM Inc files the permit before work begins. Work does not start until the permit is issued.
Step 2: Site Protection
Protective tarps are laid over landscaping, air conditioning units, and all areas below roof edges before tear-off begins.
Step 3: Tear-Off
All existing roofing layers are removed down to the decking. Debris is removed continuously to a dumpster positioned in the driveway. Two-layer tear-offs take more time and generate more disposal volume than single-layer jobs.
Step 4: Deck Inspection and Repair
Once the deck is exposed, every section is inspected. Soft or damaged panels are replaced. The homeowner is notified and authorization is obtained before any deck repair proceeds.
Step 5: Ice and Water Shield
Ice and water shield membrane is installed at all eaves, valleys, and penetration zones. In Highland Park, code requires a minimum 24-inch ice and water shield coverage at eaves due to ice dam exposure.
Step 6: Synthetic Underlayment
Synthetic underlayment is installed across the full deck surface over the ice and water shield. This provides a secondary moisture barrier behind the shingles.
Step 7: Drip Edge
Metal drip edge is installed at eaves first, then at rakes after underlayment. Drip edge directs water away from the fascia into the gutter system.
Step 8: Shingle Installation
Starter course, field shingles, and ridge cap are installed per manufacturer specifications. Nailing patterns, offset spacing, and sealing requirements are specified by the shingle manufacturer and are required for warranty coverage.
Step 9: Flashing Installation
All new flashing is installed at chimney, dormers, skylights, pipe penetrations, and valleys. Counter flashing is embedded in chimney mortar. Step flashing is woven into shingle courses.
Step 10: Final Inspection and Cleanup
A post-installation walkthrough confirms all work meets manufacturer specifications and city code. Magnetic nail sweeps are run across the full property. All debris is removed before the crew departs.
Roofing Materials for Replacement in Highland Park
Architectural Asphalt Shingles
The most common residential replacement material in Lake County. GAF Timberline HDZ and similar products carry 30-year warranties, 130 mph wind ratings, and Class A fire ratings. Class 4 impact-resistant versions of these products qualify for insurance premium discounts in Illinois and perform better under hail conditions.
Metal Roofing
Standing seam steel or aluminum systems carry 40 to 70 year lifespans. They handle snow loads and ice conditions significantly better than asphalt. Installation cost is higher — typically $22,000 to $45,000 for a mid-size Highland Park home — but maintenance costs over the full lifespan are lower.
Cedar Shake
Treated cedar shake is common in older Highland Park neighborhoods. Fire-rated treated products meet current code requirements. Cedar requires cleaning and retreatment every 5 to 7 years to maintain performance.
TPO and EPDM Membrane
Used for low-slope and flat roofs on additions and commercial properties. TPO is the current standard — it is heat-welded at seams and offers energy-reflective surface properties.
Material selection for replacements is covered through our roof replacement in Highland Park service page.

What Roof Replacement Costs in Highland Park
Replacement cost depends on roof size, pitch, material, and the scope of deck and flashing work required. These are realistic ranges for Highland Park residential projects:
- Small home up to 1,500 sq ft — architectural shingles: $8,000 to $13,000
- Medium home 1,500 to 2,500 sq ft: $13,000 to $20,000
- Larger home 2,500 to 3,500 sq ft: $20,000 to $30,000+
- Class 4 impact-resistant shingles: adds $1,500 to $3,000 over standard architectural
- Metal standing seam: $22,000 to $45,000 depending on size and profile
- Deck replacement: $80 to $150 per sheet of 4x8 OSB or plywood installed
These figures include tear-off, deck inspection, underlayment, flashing, and cleanup. Permit fees, which vary by scope in Highland Park, are either included in the JSMM Inc contract or stated separately upfront.
How Long Roof Replacement Takes
Most residential replacements in Highland Park are completed in 1 to 3 days:
- Standard residential re-roof — 1,500 to 2,000 sq ft: 1 to 2 days
- Larger or more complex roofs — 2,500 sq ft or more: 2 to 4 days
- Projects with significant deck replacement: 1 additional day
- Commercial flat roof replacement: quoted per project scope
Weather delays are common in Illinois. JSMM Inc does not install asphalt shingles below 40 degrees Fahrenheit — below this temperature, shingle adhesive does not seal properly. Weather delays are addressed in the contract before work begins.
Insurance and Roof Replacement — What Is Covered
Standard Illinois homeowner’s policies cover roof replacement caused by sudden weather events. Coverage applies to:
- Hail damage — documented impact strikes that compromise the shingle system
- Wind damage — mechanical uplift or shingle removal caused by wind events
- Storm damage — including falling trees and wind-driven debris
Coverage does not apply to:
- Age-related wear and granule loss — this is considered maintenance, not a covered event
- Pre-existing damage not caused by a covered weather event
- Roofing installed without permits that fail at a later date
Deductibles in Illinois typically range from $1,000 to $2,500 flat, or 1 to 2 percent of the dwelling coverage value for wind and hail events. Review your policy declarations page before filing to understand your specific deductible.

How to Document Storm Damage for a Replacement Claim
The documentation prepared before and during an insurance inspection determines whether a claim is approved for full replacement or reduced to partial coverage:
For step-by-step claim guidance, see our guide: how to apply for roof replacement assistance or free estimates.
- Photograph all damage from the ground and roof surface before any work begins
- Have the contractor prepare a written scope of all damage found during inspection
- File the claim as a specific weather event with the date and storm record
- Request that your contractor attend the insurance adjuster’s inspection
- Compare the adjuster’s scope against the contractor’s documentation — supplemental items are standard
- File a supplement for any items the adjuster’s scope omits before accepting the settlement

What the Permit Process Covers for Replacements
The Highland Park permit for a full roof replacement is filed by the licensed contractor — not the homeowner — and covers:
- Confirmation that the replacement scope meets City of Highland Park building code
- Verification that the installing contractor is licensed
- A permit record attached to the property that is visible in future real estate transactions
- The option for a city inspection upon completion
Replacements completed without permits create complications at resale and can result in insurance coverage issues for the new roof system. Buyers’ home inspectors check for permit records — a replacement without a permit on record is a red flag in any transaction.
What to Verify After a Roof Replacement
Before final payment is made, confirm the following:
- Drip edge is installed at all eaves and rakes
- Ridge vent or other ventilation components are properly seated and unobstructed
- All flashing is visible and tight at every penetration
- No exposed nails anywhere on the roof surface
- Shingles are straight and aligned across all slopes
- Gutters are clean and properly refastened
- Magnetic nail sweep was completed — lawn and driveway are clear
- Written completion report and warranty documentation have been provided
- Permit closeout has been confirmed or is pending city inspection
JSMM Inc provides written completion documentation with photographs before the project is closed.

Frequently Asked Questions
How many layers of shingles can I have in Highland Park?
Illinois building code permits a maximum of two layers of asphalt shingles on most residential roofs. If two layers are present, the next installation requires full tear-off.
What is the difference between RCV and ACV in a roof replacement claim?
RCV — Replacement Cost Value — pays the full cost of replacing the roof with like materials at current prices. ACV — Actual Cash Value — depreciates the settlement based on the age of the existing roof. Most standard homeowner’s policies in Illinois pay RCV. Review your policy to confirm which applies.
Do I need to be home during a roof replacement?
You do not need to be home during most of the project. JSMM Inc recommends being available by phone in case the crew discovers unexpected deck damage requiring authorization.
How long will a new asphalt shingle roof last in Highland Park?
Architectural asphalt shingles installed with proper ventilation and code-compliant underlayment in Illinois conditions typically last 25 to 35 years. Class 4 impact-resistant products extend toward the upper end of that range.
Will a roof replacement increase my home's value?
A new roof removes a common buyer objection in Highland Park real estate transactions and prevents the price reductions that an aging roof typically triggers during inspection-contingency negotiations. Class 4 shingles may also qualify for homeowner’s insurance premium reductions.
