The Hidden Dangers of Ice and Snow on Chicago Roofs: A Guide by Raincoat Roofing

Winter in Chicago is a season of breathtaking beauty but also one of significant challenges, especially for property owners. The heavy snowfalls and icy conditions characteristic of the Windy City can wreak havoc on commercial roofs. At Raincoat Roofing, we’ve seen firsthand the damage winter weather can cause and the costly repairs that follow if issues are ignored. Here, we break down the risks, signs of trouble, and preventative measures to protect your investment.

Common Roof Problems Caused by Ice and Snow

1. Ice Dams: Ice dams form when warm air from the interior rises to the roof’s surface, melting the snow. As the melted water flows to colder edges, it refreezes, creating a dam that traps further meltwater. This trapped water can seep under roofing materials, leading to leaks and water damage within the structure.
2. Snow Load Stress: Chicago’s heavy snowfalls can place excessive weight on roofs. Older structures or roofs not designed for significant loads may begin to sag or develop structural issues. For flat commercial roofs, ponding water from melting snow can also exacerbate this problem.
3. Freeze-Thaw Cycles: The fluctuating temperatures common during Chicago winters cause water to freeze and thaw repeatedly. This cycle can widen existing cracks or create new ones in roofing materials, including flashing and sealants.
4. Gutter Damage: The weight of ice and snow can strain or detach gutters, leading to drainage issues. When gutters fail, melting snow can cascade directly onto walls or foundations, causing further damage.

Warning Signs to Watch For

Property owners should stay vigilant for signs of roof distress during winter. Key indicators include:

• Persistent ice dams along the edges of the roof
• Sagging rooflines or interior ceiling cracks
• Water stains or leaks on walls and ceilings
• Detached or damaged gutters

Proactive Steps to Protect Your Roof

1. Ensure Proper Insulation and Ventilation: Proper insulation and ventilation help maintain a consistent roof temperature, preventing the formation of ice dams.
2. Clear Snow Safely: Regular snow removal from roofs can prevent excessive loads. For commercial properties, professional snow removal services are a safer option to protect roofing membranes.
3. Inspect Regularly: Conducting routine roof inspections before and after the winter season can help identify potential vulnerabilities.
4. Invest in Gutter Protection: Installing heated gutter systems or guards can prevent ice buildup and improve drainage efficiency.
5. Schedule Professional Maintenance: Partnering with a trusted roofing company like Raincoat Roofing ensures that small issues are addressed before they become major problems.
