The slips nobody plans for: Winter fall hazards that catch roofing crews off guard

By Cotney Consulting Group. 

Cold weather demands a different pace, different planning and different expectations

Most roofing companies prepare for winter by considering shorter days, material limitations and weather delays. What often gets less attention is how cold weather quietly changes jobsite conditions, making slips and falls more likely. 

Winter falls don’t always happen during storms. They occur on clear mornings, during routine access and while crews are doing tasks they’ve done hundreds of times before. That’s what makes them dangerous and preventable. 

Cold weather changes the jobsite before work even starts 

One of the biggest mistakes crews make in winter is assuming conditions are safe just because the roof looks dry. Frost, condensation and overnight moisture don’t always show up from the ground. By the time a worker realizes footing is compromised, they’re already committed to the step. 

Common winter slip hazards include: 

• Frost on membranes and metal surfaces 
• Condensation on roof decks and ladders 
• Ice forming near drains, curbs and edges 
• Snow melt refreezes overnight 
• Slick access points that weren’t an issue the day before 

These hazards don’t announce themselves. They require intentional inspection before anyone steps onto the roof. 

Morning access is one of the highest-risk moments 

Many winter falls happen before production even begins during access. Ladders, scaffold platforms and roof hatches are often colder and slicker than the work surface itself. Gloves reduce grip. Boots stiffen. Hands are cold. Balance is compromised. 

Safe winter access requires: 

• Clearing and inspecting ladders before use 
• Ensuring rungs are dry and free of ice 
• Confirming tie-offs are secure despite cold-induced material stiffness 
• Slowing down entry and exit 

Rushing access in winter is one of the fastest ways to get hurt. 

Materials behave differently in the cold 

Roofing materials don’t respond the same way in winter. Membranes stiffen. Granules loosen. Sealants cure more slowly. Walking paths that feel stable in summer may not offer the same traction in cold conditions. This creates a false sense of confidence. Workers step where they usually would only to find the surface reacts differently. 

Crews should: 

• Establish designated walk paths early 
• Avoid stepping near edges, penetrations or transitions without testing footing 
• Use temporary walk pads where possible 
• Adjust expectations for speed and movement 

Winter work requires deliberate movement, not muscle memory. 

Footwear and traction matter more than ever 

Footwear is often overlooked until something goes wrong. In winter, worn boots, hardened soles or slick tread patterns significantly increase the risk of falls. Cold temperatures reduce traction even on “non-slip” footwear. Add moisture, and the margin for error disappears. 

Supervisors should reinforce: 

• Inspecting boots for wear 
• Replacing footwear that has lost grip 
• Using traction aids when conditions warrant 
• Avoiding smooth-soled or hardened boots 

Sound footing is one of the simplest and most effective fall prevention tools. 

Housekeeping is a winter safety tool 

Debris that might be manageable in warm weather becomes hazardous in winter. Loose materials, dust, granules and scraps freeze into slippery patches when moisture is present. 

Winter housekeeping should include: 

• More frequent cleanup 
• Removing loose materials promptly 
• Clearing snow and ice from work areas 
• Keeping walk paths clean and visible 

Clean sites aren’t just professional, they’re safer when temperatures drop. 

The pressure to “push through” makes winter risk worse 

Winter roofing often comes with schedule pressure. Short daylight hours, backlog and customer urgency can push crews to work when conditions aren’t ideal. This is where leadership decisions matter most. 

Crews need clear guidance on: 

• Go/no-go decisions 
• When to delay access 
• When surfaces are unsafe regardless of the schedule 

Stopping or delaying work due to winter conditions is not overreacting; it’s managing risk responsibly. 

Toolbox talks should shift with the season 

Winter safety can’t be an afterthought. Toolbox talks should change with the conditions crews are facing. 

Practical winter talks cover: 

• Morning surface inspections 
• Access hazards 
• Changes in material behavior 
• Weather forecasts and temperature swings 
• End-of-day cleanup to prevent overnight freezing 

Seasonal communication keeps crews alert to risks they might otherwise overlook. 

End-of-day decisions affect tomorrow’s safety 

Many winter slip hazards form after crews leave the site. Water left in low spots freezes overnight. Debris traps moisture. Poor cleanup becomes tomorrow’s accident. 

Before leaving, crews should: 

• Remove standing water where possible 
• Clear loose materials 
• Secure access points 
• Consider overnight weather conditions 

A few extra minutes at the end of the day can prevent a serious injury the next morning. 

Final thoughts

Winter slip-and-fall hazards don’t come from dramatic storms alone. They come from small, predictable changes in conditions that crews stop noticing because the work feels familiar. 

Cold weather demands a different pace, different planning and different expectations. The companies that recognize this and adjust accordingly keep their crews safer and their projects moving. 

In winter roofing, the most dangerous step is the one taken without thinking.
