Written by ADMIN_TEAM in Moline, Illinois | Published: February 27, 2026

Technical Brief

The recent storm in Moline, Illinois, has posed severe risks primarily due to the threat of ice damming and freezing leak risk. With temperatures dropping to -1.8°C, the buildup of ice can lead to significant structural issues if not addressed promptly. Homeowners are urged to Request a Professional Roof Inspection to evaluate potential vulnerabilities in your roofing system.

Damage Analysis

Ice damming can occur along the eaves of your roof, leading to meltwater intrusion beneath shingles. This intrusion, coupled with possible membrane flashing failures, poses risks of extensive water damage. Although wind speeds reached only 18.4 km/h, fastener pull-through can still be a concern, especially in older roofing systems. Additionally, with minimal precipitation, the underlayment saturation is a lesser issue but still warrants inspection to ensure flashing integrity is maintained.

Local Neighborhood Impact

Areas particularly at risk in Moline include:

• South Park
• Historic Downtown Moline
• Green Valley
• Broadway Historic District

Residents in these neighborhoods should be vigilant, as the combination of freezing temperatures and potential ice dams can lead to serious leak issues.

Protective Measures

To mitigate the risks associated with ice damming, homeowners should consider the following protective measures:

• Ensure proper attic insulation and ventilation to prevent heat buildup.
• Regularly clear gutters and downspouts to facilitate proper drainage.
• Install heated cables on roof edges to prevent ice buildup.
