Commercial properties in Lansing face some of the toughest winter conditions in Michigan. Heavy snow, accumulating ice, freezing temperatures, and fluctuating weather patterns all place significant stress on commercial roofing systems. Each winter, property managers across Michigan experience leaks, structural concerns, and emergency repairs that could have been prevented with a strong winter roof preparation plan.
Preparing a commercial roof before the first snow arrives is one of the most important steps a building owner can take to protect the structure, interior assets, and ongoing operations. Even minor vulnerabilities can turn into major issues once snow and ice settle on the roof. When temperatures drop, small cracks can expand, weak seams can open, and blocked drainage can trap water beneath snow loads. These problems do not stay isolated for long. Winter has a way of revealing every weakness.
This blog explains the essential steps for effective winter roof preparation, why it matters for Lansing’s climate, and how commercial property managers can reduce risks, prevent damage, and keep their buildings protected all season long.
Why Winter Preparation Matters for Commercial Roofs in Lansing
Winter in Lansing brings long periods of snow coverage, frequent freeze-thaw cycles, and sharp temperature drops. These conditions challenge even the strongest commercial roofing systems. Unlike light rain or short-term storms, winter weather places continuous stress on materials for months at a time.
Heavy snow creates extra weight that the roof must support. Ice can form around drains or equipment, block outlets, and cause water intrusion as temperatures fluctuate. Wind can push snow into vulnerable seams. Moisture can accumulate beneath old or damaged membranes and freeze, causing expansion that weakens the roof from the inside.
Without proper winter roof preparation, these seasonal conditions can lead to:
- More frequent leaks
- Damaged insulation
- Structural strain or sagging
- Ice buildup around equipment or edges
- Emergency repair costs during the coldest months
A proactive approach reduces the likelihood of breakdowns and strengthens the roofing system before conditions become severe.

Start with a Professional Pre-Winter Inspection
The most important step in any winter roof preparation strategy is a detailed inspection completed before snowfall begins. Even commercial roofs that appear to be functioning well may have hidden problems that only a trained roofer will catch.
During a pre-winter inspection, a qualified roofing contractor can identify concerns such as:
- Early membrane deterioration
- Weak seams or punctures
- Areas showing sagging or unevenness
- Blocked or restricted drainage
- Loose or compromised flashings
- Damage around rooftop HVAC units
Addressing these issues early prevents them from worsening under snow and ice. A pre-winter inspection also creates a baseline understanding of the roof’s overall condition, helping property managers plan maintenance and manage long-term budgets.
By The Square Roofing routinely performs these inspections for commercial properties in Lansing to ensure every roof is winter-ready before the first major snowfall.
Repair Existing Damage Before Snow Arrives
Once weaknesses are identified, completing repairs early in the season is critical. Winter temperatures make roofing materials less flexible, and adhesives or sealants do not perform well in extreme cold. Snow can also hide damage, making it harder to reach or repair safely.
Taking time to repair issues before the season changes is a key part of effective winter roof preparation. Small problems that go unresolved in fall often transform into larger, more costly issues during winter.
Address Drainage Issues to Prevent Ice Build-Up
Drainage is one of the most important factors in winter roof performance. Flat and low-slope commercial roofs must efficiently move water off the surface. If drains, scuppers, or gutters become blocked or slow, meltwater cannot escape. When temperatures drop again, this trapped water freezes and expands, which increases pressure on the roofing membrane.
This cycle of melting and refreezing can damage membranes, loosen flashings, and cause water to back up into the building during thaw periods.
A proper winter roof preparation plan includes clearing and testing drainage systems. Property managers should ensure:
- Drains are free of debris
- Gutters and downspouts are clear and functional
- Scuppers and overflow drains are unobstructed
- Protective screens are intact and not restricting water flow
If drainage is not working properly before winter, it will be even less effective during snow and ice.
Check Flashings and Edge Details
Flashings protect the most vulnerable parts of a commercial roof, including edges, transitions, walls, curbs, and penetrations. These areas are also the most prone to leaks during winter.
Cold temperatures cause materials to contract. When flashings or metal details are already loose or aging, this contraction increases the risk of separation. Snow and ice then push into these gaps, allowing water to migrate beneath the roof system.
During winter roof preparation, all flashings should be inspected closely for cracks, gaps, separation, and deterioration. Securing these components before winter maintains a watertight barrier where the roof needs it most.
Prepare for Heavy Snow Loads
Lansing routinely experiences heavy snowfall, and accumulation on a commercial roof adds significant weight. While buildings are designed to support snow, older or weakened roofs may struggle to handle prolonged snow loads.
Winter roof preparation should include reviewing the roof’s structural condition. Areas with sagging insulation, soft spots, or uneven surfaces may not support heavy loads as safely. Property managers should have a plan for snow removal if accumulation reaches dangerous levels.
Snow removal must be performed by trained professionals using the correct tools. Improper removal or DIY removal can damage membranes, puncture the roof, or loosen seams. A safe removal plan ensures the roof stays protected without creating new problems.
Protect Rooftop Equipment
Commercial roofs in Lansing often support HVAC units, ventilation systems, generators, satellite equipment, and electrical components. These units can create snow traps, increase ice buildup, and cause additional wear around their bases.
During winter roof preparation, property managers should:
- Inspect all equipment curbs for tight seals
- Ensure panels are closed and secure
- Confirm that exhaust vents and air intakes are clear
- Make sure no loose components may shift during storms
Equipment that is not properly sealed or maintained becomes a major source of winter leaks.
Monitor for Ice Dams and Icicles
Ice dams form when snow melts during the day and refreezes near the roof edge at night. This is especially common in Michigan due to frequent freeze-thaw cycles. Ice dams prevent water from draining properly and push moisture back toward vulnerable areas of the roof.
Icicles are another sign of drainage issues and can add dangerous weight to gutters. When icicles grow too large, they may pull gutters away from the building or create safety risks for pedestrians below.
Part of winter roof preparation involves keeping an eye on these conditions throughout the season. Consistent monitoring helps prevent larger problems from forming and allows property managers to respond quickly when necessary.

Evaluate Insulation and Heat Loss
A commercial roof that loses heat can contribute to snow melting unevenly, which leads to ice buildup, ponding, and freeze-thaw damage. Inadequate insulation also increases energy costs during winter.
Improving insulation as part of winter roof preparation helps:
- Maintain interior temperatures
- Reduce HVAC strain
- Prevent unnecessary heat loss
- Minimize uneven melting across the roof surface
Better insulation provides long-term benefits beyond winter, making it a cost-effective improvement for many Lansing properties.
Create a Winter Maintenance Plan
Winter conditions in Lansing change quickly. Snow, freezing rain, and cold temperatures can all affect the roof differently at various points in the season. Having a maintenance plan in place keeps property managers proactive rather than reactive.
A solid winter roof preparation plan includes:
- Scheduled mid-winter checkups
- A snow removal strategy
- A list of emergency contacts
- Instructions for on-site staff
- Regular monitoring after each significant weather event
This blueprint keeps the roof protected and helps avoid emergency calls during severe weather.
Know When It Is Time to Consider Replacement
Even with strong winter roof preparation, some roofs are too aged or damaged to perform reliably through the season. Lansing’s winters will expose existing weaknesses quickly. If the roof already shows signs of widespread membrane cracks, recurring leaks, ponding, or severe aging, the better long-term solution may be replacement rather than seasonal maintenance.
Winter is not always the best time for a full replacement due to weather limitations, but planning ahead ensures the roof can be replaced as soon as the weather allows in spring.
