What Homeowners in Robinson, IL Should Check Now

Flood warnings classified as Severe by the National Weather Service can produce standing water, saturated ground, drainage backups, and water intrusion into structures. Even if your home did not experience visible flooding, the conditions that accompany a Severe Flood Warning can stress roofing systems, foundations, drainage pathways, and exterior materials in ways that are not always immediately visible.

Once it is safe to do so, homeowners in Robinson and throughout Crawford County should walk their property and check the following areas:

Roof

• Look for missing, lifted, or displaced shingles from any wind-driven rain that accompanied the event.
• Inspect ridge caps and flashings around chimneys, vents, and skylights for gaps or separation — these are among the most common points of water entry.
• Check attic spaces for moisture, water stains on rafters or roof decking, or any daylight visible through the deck.
• Note granule accumulation in gutters or downspout discharge areas, which can indicate shingle erosion.

Gutters and Downspouts

• Clear any debris — leaves, branches, sediment — that may have washed into gutters during the storm. Blocked gutters are a leading cause of fascia rot and water intrusion at the roofline.
• Confirm that downspouts are properly attached and directing water at least four feet away from the foundation.
• Look for gutter sections that may have pulled away from the fascia under the weight of standing water or debris.

Siding and Exterior

• Walk the full perimeter of your structure looking for cracked, buckled, or missing siding panels.
• Check window and door frames for signs of water infiltration, warping, or failed caulking.
• Inspect trim boards at and near ground level for soft spots or swelling that may indicate water absorption.

Trees and Landscaping

• Assess trees near the structure for uprooted root systems, split or cracked limbs, or significant lean — all of which can present delayed hazards after ground saturation.
• Remove or clearly flag any large debris that came to rest against the home’s exterior.

Water Intrusion and Interior

• Check basement walls and floors for seepage, new cracks in masonry, or efflorescence — the white mineral deposits that signal water movement through concrete or block.
• Inspect window wells on below-grade windows, which can become collection points during flood conditions.
• Check crawl spaces if accessible and safe, looking for standing water or saturated insulation.
• Examine interior ceilings and upper walls for staining, discoloration, or soft drywall, which may indicate roof or wall penetration.

Do not enter any portion of your home where standing water is present until you have confirmed that electrical systems serving that area are de-energized. If you are uncertain, contact your utility provider before re-entering. Ready.gov offers guidance on staying safe after a flood event, including steps for returning to a flooded property.

If You Find Damage

Discovering storm or flood damage can feel overwhelming, but a methodical approach in the first 24 to 72 hours can significantly affect the outcome of a property insurance claim and the speed of your overall recovery.

Document Before Any Work Begins

Before removing debris, making repairs, or allowing anyone to begin work on your property, photograph and video every area of visible damage. Capture wide-angle shots for context and close-up images for detail. Record the date and time. This documentation is the foundation of any insurance claim and typically the first item an adjuster will request.

Take Reasonable Steps to Prevent Further Loss

If a portion of your roof has been compromised, temporary protective measures — such as a professionally installed tarp — are typically covered under most homeowner policies as emergency mitigation. Keep all receipts for emergency services and materials. Avoid committing to permanent repairs before your insurance company has had an opportunity to inspect the damage and document the scope.

Notify Your Insurance Company Promptly

File your claim as soon as possible. Most policies carry notice requirements, and delays can complicate coverage decisions. Have your policy number, a description of affected areas, and your photographic documentation ready when you call. Your insurer will assign an adjuster who will schedule an on-site inspection.
