Whether you're planning ahead or dealing with an emergency replacement, understanding the roofing timeline in Illinois helps you prepare your home and your schedule.

What Impacts Roof Installation Duration?

Every home is different, and no two roofing projects are exactly the same. That’s why there’s no universal answer to how long it takes.

But here are the main factors that affect the roof installation duration:

• Size of your roof – Larger roofs take more time to remove and replace.
• Pitch (steepness) – Steeper roofs require more safety equipment and time.
• Material used – Asphalt shingles are quicker to install than tile or slate.
• Weather conditions – Rain, wind, or snow can delay installation.
• Structural damage – Rotten decking or framing issues may extend the project.
• Crew size – More workers usually mean faster completion.

So, depending on these variables, a typical replacement could take anywhere from one day to several days.

Average Roofing Timeline in Illinois

Now let’s break down the roofing timeline in Illinois so you can get a better idea of what happens each day.

1. Inspection and Estimate (1–3 Days)

Before the physical work begins, a roof inspection is performed by a contractor.

This includes:

• Assessing the condition of shingles, decking, and flashing
• Identifying leaks or structural concerns
• Recommending replacement or repairs

After the inspection, you’ll receive an estimate. Most contractors can provide this within 24–72 hours.

2. Permits and Scheduling (2–7 Days)

In many Illinois cities, a permit is required before roof work begins. The contractor typically handles this process. Depending on the municipality, permit approval can take 2–7 business days.

During this time, your project will be added to the roofing company’s schedule. The wait time may be longer during peak seasons (spring and summer).

3. Roof Material Delivery (1–2 Days Before Project)

Once the date is set, roofing materials are ordered and delivered to your home. Delivery usually happens 1–2 days before installation begins. Materials are either placed on the ground or directly on the roof, depending on space and weather.

4. Tear-Off Phase (1 Day)

The tear-off is when the old roofing system is removed down to the decking.

This includes:

• Removing old shingles or tiles
• Disposing of underlayment and flashing
• Inspecting the exposed decking

This process generally takes one full day for average-sized homes (2,000–3,000 square feet).

5. Decking Repairs (0.5–1 Day)

If your contractor finds soft spots or rot in the decking, those sections must be replaced. Minor repairs might add half a day. If extensive repairs are needed, expect an additional full day.

How Long Does Roof Replacement Take in Illinois (By Material Type)?

The material you choose for your roof has a direct impact on the roof installation duration. Here's a rough estimate by material:

• Asphalt shingles: 1–2 days (most common in Illinois)
• Metal roofing: 2–4 days
• Wood shakes or shingles: 3–4 days
• Slate or tile roofing: 5–7+ days (due to weight and complexity)

In Illinois, asphalt shingles dominate the market because they’re durable, budget-friendly, and fast to install.

Weather Delays Are Common in Illinois

Illinois weather is no joke. Between sudden thunderstorms in spring and icy conditions in winter, expect possible delays.

Roofers may pause work due to:

• Rain or lightning
• High winds
• Snow accumulation or ice
• Extreme heat

Pro Tip: Always have a buffer in your schedule. Even if the crew says 2 days, give it 3–4 to be safe.

Additional Factors That May Extend the Timeline

Sometimes, unexpected issues arise. Here are a few things that can add time to the roofing timeline in Illinois:

• Change orders – Deciding to switch materials or add skylights mid-project
• Insurance delays – If the roof is part of a storm damage claim, paperwork may slow things down
• Hidden damage – Mold, pests, or structural damage found during tear-off
• Special features – Chimneys, valleys, dormers, or solar panels can complicate installation

Being aware of these ahead of time helps avoid surprises.

What You Can Do to Speed Up the Process

While you can’t control the weather, you can take steps to help your contractor stay on schedule:

• Clear your driveway and yard so the crew has space for equipment
• Secure pets indoors and inform your neighbors
• Ask questions early—don't wait until the work starts
• Choose an experienced, licensed contractor who knows Illinois building codes
• Stick to your original plan to avoid delays from last-minute changes

By being proactive, you can help ensure a smoother experience.

Final Clean-Up and Inspection (0.5–1 Day)

After installation is complete, your contractor will clean up the job site. This includes:

• Removing debris and leftover materials
• Sweeping your lawn with a magnetic roller for nails
• Final inspection of the roof and gutters
• Walking through the project with you

This phase usually wraps up in less than a day.

Realistic Roofing Timeline for Illinois Homeowners

So, let’s put it all together. For an average roof replacement in Illinois, here’s what you can realistically expect:

Total Estimated Time: 5 to 10 working days (weather permitting)

This estimate covers the full roof installation duration from inspection to clean-up, not just the installation days.
