Winter in Chicagoland brings serious risks to commercial roofing systems. Snow accumulation, freezing temperatures, and repeated thaw cycles can create dangerous ice buildup across flat and low-slope roofs. And when drainage systems become blocked by ice, water can back up and pond on the roof surface, increasing the risk of leaks, structural stress, and interior damage.
This guide explains how ice-related problems develop on commercial roofs and how professional ice removal using an Arctic Steamer provides a safe, effective solution for Chicagoland properties.
Commercial buildings face a serious winter challenge with ice blocking drainage pathways and trapping water on the roof surface.
Flat and low-slope roofs rely on drains, scuppers, and internal piping to move water off the building. When freezing temperatures interfere with these systems, melted snow can refreeze and prevent proper drainage. The result is water that backs up, ponds, and eventually freezes again.
Several conditions commonly contribute to ice-related problems on commercial roofs.
When snow melts due to solar heat or building heat loss, water flows toward roof drains. If those drains freeze or become blocked by snow and ice, water cannot escape the roof.
This can lead to ponding water that later freezes into thick ice layers, increasing structural load and placing additional stress on the roofing system.
Water leaving the roof can freeze where it exits through scuppers or at parapet edges. As ice builds up, it can trap additional meltwater behind it, forcing water to remain on the roof surface longer than intended.
Repeated freeze–thaw cycles in these areas can weaken flashings and roofing seams.
Inconsistent insulation or air leakage can create warm and cold zones across the roof surface. Snow may melt in warmer areas but refreeze when it reaches colder parts of the roof.
These ice ridges often develop around mechanical curbs, skylights, expansion joints, and perimeter walls.
Wind-driven snow can accumulate unevenly across commercial roofs. When drifted snow melts and refreezes in colder areas, localized ice buildup can form near drains or roof transitions.
These conditions increase the risk of blocked drainage and excessive ponding.
Ice buildup is a direct threat to building integrity and safety. Water infiltration caused by ice can damage insulation, ceilings, walls, and electrical systems, creating costly repairs and potential liability issues.
For businesses, these problems often translate into operational disruptions, tenant complaints, and emergency repair expenses. In severe cases, prolonged moisture exposure can lead to mold growth and compromised indoor air quality.
Ignoring ice buildup or delaying removal increases the likelihood of long-term roof damage. That’s why removal of ice should always be treated as a priority during winter months, especially for flat and low-slope commercial roofs common throughout Chicagoland.
Many property managers are tempted to handle ice removal in-house, but common DIY methods often create more problems than they solve. Tools like axes, hammers, or shovels can puncture roofing membranes, damage flashings, and void warranties.
Chemical solutions such as salt or calcium chloride may melt ice temporarily, but they can corrode metal components and degrade roofing materials over time. Additionally, uneven melting can refreeze water in other areas, worsening the problem.
Without proper training and equipment, DIY ice removal increases the risk of personal injury and accidental roof damage. For commercial properties, these risks usually outweigh any perceived cost savings.
The Arctic Steamer is a specialized ice removal system manufactured by American Pressure. It uses low-pressure, high-temperature steam to melt ice safely and precisely without damaging roofing materials.
Unlike mechanical methods, steam penetrates ice gradually, allowing controlled removal without impact or abrasion. The steamer melts channels through the ice, creating pathways for trapped water to drain properly off the roof.
As an ice steamer, this system is especially effective on commercial roofs where delicate membranes, seams, and drainage systems must be protected during removal.
Ice removal with steam offers several advantages over conventional techniques. The Arctic Steamer operates at low pressure, which means it won’t force water under roofing materials or compromise seals.
Steam also eliminates the need for chemicals that can damage roofs and surrounding components. Because the process is controlled and precise, technicians can target problem areas without disturbing intact sections of the roof.
For commercial buildings, using a steamer for ice removal significantly reduces the risk of accidental damage while delivering faster, more reliable results.
Professional ice removal offers a level of safety and effectiveness that DIY methods simply can’t match. When performed by trained technicians, steam-based removal protects the roof while resolving the underlying issue.
Key benefits include:
For property managers responsible for large or multi-tenant buildings, these benefits make professional ice removal a practical and responsible choice.
When Showalter Roofing performs ice removal using an Arctic Steamer, the process begins with a thorough roof assessment. Technicians identify ice buildup patterns, drainage points, and vulnerable roof components before starting removal.
The steamer is then used to carefully melt channels through the ice, restoring proper water flow. Throughout the process, care is taken to protect roofing materials and ensure no additional moisture intrusion occurs.
Once removal is complete, the roof is inspected to confirm drainage is functioning correctly and no damage has occurred. This methodical approach ensures safe, effective removal without unnecessary risk.
Recurring ice buildup is often a sign of broader roof or drainage issues. Learn how ongoing commercial roof maintenance from Showalter Roofing can help identify insulation gaps, drainage problems, and wear that contribute to ice formation.
While ice removal is essential when problems arise, prevention is the most cost-effective long-term strategy. Preventing ice building involves addressing the conditions that allow them to form in the first place.
Common prevention measures include improving insulation, sealing air leaks, ensuring proper roof drainage, and maintaining gutters and downspouts. Regular roof inspections before winter can identify vulnerabilities that increase ice risk.
For commercial buildings, proactive maintenance combined with professional assessments helps reduce the frequency and severity of ice issues year after year.
Ice removal requires experience, training, and an understanding of commercial roofing systems. Showalter Roofing brings all three to every winter service call.
By using professional-grade tools like the Arctic Steamer by American Pressure, we ensure ice buildup is removed safely and effectively. Our team understands Chicagoland weather conditions and how winter impacts commercial roofs specifically.
If your commercial property is dealing with ice buildup, don’t risk damage with improper removal methods. Professional ice removal using an Arctic Steamer provides a safe, non-invasive solution designed for commercial roofing systems.
