As winter gives way to spring across Chicago and Northwest Indiana, property managers and business owners should take the opportunity to assess one of their most important assets: the roof. Commercial buildings face year-round exposure to the elements, and after months of snow, ice, and fluctuating temperatures, spring is the ideal time to identify and address any issues caused by winter weather. 

Regular roof maintenance in spring helps prevent minor issues from turning into larger, more disruptive problems down the line. It also supports the long-term performance of your building and helps avoid water intrusion that can damage interiors or equipment. 

The Impact of Winter on Commercial Roofs 

Flat and low-slope roofs common on commercial buildings are especially affected by Midwest winters. Heavy snow, ice buildup, and wind-driven debris can put pressure on drainage systems and roofing materials. Frequent freeze-thaw cycles—where melting snow or ice refreezes at night—can worsen existing vulnerabilities. This repeated expansion and contraction stresses roofing membranes, loosens flashing, and may lead to cracks or separation at seams. 

As spring temperatures rise and rainfall increases, roofs that haven’t been cleared or inspected may struggle to manage water flow, increasing the risk of leaks and water damage. 

Common Debris and Why It Matters 

One of the biggest issues seen in spring is the accumulation of leaves and organic material on the roof surface. When left in place, leaves absorb and hold moisture, especially after rain. This moisture sits directly on the roof membrane, which can lead to deterioration over time. On flat roofs, this damp buildup is often found around drains, corners, or around rooftop units where airflow is reduced. 

In addition to moisture retention, this debris can block roof drains, scuppers, and gutters, making it difficult for water to move off the roof. This increases the chance of pooling water, which adds weight to the structure and may eventually penetrate roofing layers. 

Wind-blown branches, trash, and other debris also commonly collect around mechanical equipment or in low-lying areas. If not removed, these materials can mask signs of damage and make it harder to inspect the roof later in the season. 

Spring Cleaning Tips for Commercial Properties 

Property teams should begin by inspecting the roof for debris buildup, standing water, or visible damage. Clear off leaves, sticks, and any other material that may be holding moisture. Be cautious not to push debris into drains or seams. Clean all gutters and downspouts, and make sure internal roof drains are not clogged. 

Check flashing, seams, and any areas where water may have frozen repeatedly during the winter. Signs of blistering, cracking, or separation may indicate that freeze-thaw cycles have stressed the system. Any such findings should be evaluated by a roofing professional. 

Trimming back overhanging branches now can also help reduce new debris accumulation during spring and summer storms. 

Call in a Trusted Roofing Partner 

While basic cleaning and visual checks can be done by facility staff, a thorough spring inspection by a qualified contractor offers a more complete picture. A professional can spot early signs of trouble, test drainage flow, and recommend repairs if needed—especially after a rough winter.
