Protecting Your Roof from Midwest Thunderstorms and Heavy Rain

The Midwest is no stranger to unpredictable weather, especially during the spring and summer months when thunderstorms and heavy rainfall are most common. For commercial property owners, this presents an ongoing challenge: keeping roofing systems resilient and watertight in the face of increasingly volatile conditions. The key to minimizing damage and avoiding costly repairs lies in preparedness and regular maintenance.

Understanding the Impact of Midwest Storms on Roofing Systems

Midwest thunderstorms bring more than just rain—they come with high winds, hail, and rapid temperature shifts, all of which can strain even the most durable roofing materials. Flat and low-slope commercial roofs are particularly vulnerable to water pooling and drainage issues.

Common issues caused by severe storms:

• Membrane punctures from wind-blown debris or hail.
• Clogged drains that cause water buildup and interior leaks.
• Loosened flashing and seams that allow moisture infiltration.
• Structural stress from prolonged standing water.

Steps to Prepare Your Roof for Storm Season

1. Schedule a Pre-Storm Inspection

Having a professional inspect your roof before storm season begins is one of the most effective ways to identify and address vulnerabilities. An experienced roofing contractor will check for loose materials, clear debris, and assess the condition of drainage systems and flashings.

2. Keep Drains and Gutters Clear

Stormwater must flow freely off your roof to prevent leaks and water damage. Regularly cleaning and maintaining roof drains, gutters, and scuppers ensures water doesn’t pool and add stress to the roof structure.

3. Secure Flashing and Roofing Materials

Strong winds can lift flashing or loosen seams around roof penetrations such as vents and HVAC units. Ensuring these areas are sealed and secure helps prevent wind-driven rain from getting into your building.

Benefits of a Professional Maintenance Plan

While one-time inspections are helpful, enrolling in a professional roof maintenance program offers long-term protection. Regular check-ups after severe weather events can identify emerging issues before they escalate, reducing the risk of unexpected damage and repair costs.

Great Lakes Roofing offers tailored preventative maintenance plans that include scheduled inspections, detailed reporting, and timely repairs—designed to meet the needs of each unique roofing system.

What to Do After a Storm Hits

Even with preparation, some storms are too intense to avoid damage entirely. After a major weather event:

• Visually inspect the interior for signs of leaks, water stains, or bubbling paint on ceilings and walls. These could be early indicators of roof compromise.
• Check for exterior damage if it’s safe to do so. Look for missing flashing, debris accumulation, or sagging areas on the roof.
• Report any visible damage to your contractor as soon as possible. Quick documentation—photos and notes—can help with insurance claims and ensure priority response.
• Avoid DIY fixes, as temporary patches may worsen the problem or void warranties. Professional repairs are not only safer but also ensure the longevity of your roofing system.
• Request a professional post-storm inspection to catch issues that may not be immediately visible but could worsen over time.
