• Final Steps After the Inspection

In this article, we’ll walk you through a detailed roofing assessment in Illinois, tailored for local homeowners facing our unique Midwest climate.

What Is a Pre-Roof Replacement Inspection?

A pre-roof replacement inspection is a full evaluation of your current roof system. This step helps identify underlying issues like rot, leaks, and structural problems that may not be visible from the ground.

An inspection also:

• Confirms if a full replacement is needed
• Helps you choose the right materials
• Provides an accurate estimate
• Prepare your home for the new roof installation

Think of it as a health checkup before surgery. You wouldn’t want a contractor installing a brand-new roof over moldy decking or unstable rafters.

Who Should Perform the Roofing Assessment?

It’s tempting to climb a ladder and check things out yourself—but for safety and accuracy, it’s always best to hire a licensed roofing professional.

A qualified expert will understand:

• Illinois building codes
• Local climate effects on roofing systems
• Common signs of wear from ice dams, wind, or hail
• How to safely access steep or complex rooftops

Hiring a pro ensures nothing gets missed in your roofing assessment in Illinois.

Roof Inspection Checklist Illinois Homeowners Should Follow

Let’s dive into the full checklist. This is the process that most reputable contractors follow when inspecting your roof before a replacement.

1. Exterior Roof Evaluation

The first part of the inspection focuses on what’s visible from the outside.

Key points include:

• Shingle condition – Look for curling, cracking, or missing shingles
• Granule loss – Bare spots can mean the shingles are aging
• Flashing – Check metal pieces around chimneys, vents, and valleys
• Gutters and downspouts – Are they clogged, detached, or rusted?
• Rooflines – Sagging or uneven lines could mean structural problems
• Drip edge – This metal trim protects the roof’s edge from water—make sure it’s there and in good shape

These signs can give a strong indication of whether a full replacement is needed or if minor repairs will do the trick.

2. Interior Inspection: Attic and Ceilings

Next, inspectors will check inside your attic and ceilings for warning signs.

Common issues include:

• Water stains or mold – Clear signs of leaks or moisture buildup
• Daylight through boards – Indicates holes or cracked decking
• Sagging insulation – Could be saturated with water
• Unpleasant odors – Mildew from trapped moisture
• Ventilation check – Proper airflow prevents heat and moisture buildup

This part of the pre-roof replacement inspection is crucial. Often, the most expensive problems hide below the surface.

3. Decking Assessment

After checking the shingles and attic, the inspector will look at the decking—the wooden boards that make up the foundation of your roof.

Inspectors look for:

• Soft or spongy spots – Signs of rot or long-term water exposure
• Loose nails or lifted panels – Indicate age or moisture damage
• Warped wood – Can lead to future leaks or poor installation of new shingles

If decking problems are found, they’ll need to be replaced before installing a new roof. This impacts both the cost and roof installation duration.

4. Flashing and Sealant Condition

Flashing is the metal material installed around roof joints to keep water out. Sealants are used to close gaps or holes.

Inspectors will check:

• Metal flashing – Rusted, bent, or missing pieces
• Sealant cracks or gaps – Especially around skylights, vents, or chimneys
• Kickout flashing – Guides water away from siding; missing ones can cause serious wall damage

This step ensures your new roof will be watertight from every angle.

5. Roofing Accessories and Penetrations

A solid roof inspection checklist Illinois residents can trust also includes reviewing accessories and penetrations.

These are areas where leaks often form:

• Pipe boots – Rubber seals around plumbing vents should be intact
• Roof vents – Should be free of rust and damage
• Satellite dishes or solar mounts – Improper installations can cause leaks
• Skylights – Check the seals and glass for signs of wear or moisture

Your inspector should recommend removing, replacing, or re-flashing these areas before your new roof goes on.

6. Structural Review

This last part involves looking at the roof’s overall structure.

What to check:

• Roof slope – The pitch impacts drainage and roofing material options
• Support beams or trusses – Look for signs of shifting or cracking
• Load-bearing capacity – Important if switching to a heavier material like slate or tile

A strong structure ensures your new roof won’t just look good—it’ll last.

Why a Roofing Assessment in Illinois Is Different

Illinois homes face a wide range of weather: snow, ice, wind, hail, and summer heat. That’s why a roofing assessment in Illinois needs to be extra thorough.

Unique considerations include:

• Ice dam risks in winter – Make sure proper ventilation and insulation are in place
• Storm damage – Hail can cause bruising to shingles and flashing
• Wind uplift – Older shingles may not meet modern wind rating standards
• Heavy snow loads – Ensure your structure can handle it

Local roofing pros are familiar with these challenges and can offer better recommendations than out-of-state companies.

Final Steps After the Inspection

Once the inspection is complete, your contractor should:

• Provide a written report of findings
• Explain which parts of the roof need replacement
• Offer estimates for different materials
• Help with permits or insurance paperwork, if needed
• Schedule the replacement when you're ready

Taking time to do a full pre-roof replacement inspection saves money, time, and future headaches.
