What Does the Freeze/Thaw Cycle do to Your Roof?

Mild winter weather may seem harmless to your roof but can actually damage it. When snow or rainwater on your roof freezes before it can run off, the ice can damage roofing materials. During a mild winter, water on the roof can freeze and thaw over and over. This can eventually damage the roofing materials or separate flashing from around the chimneys, ducts, and vents. That kind of damage can lead to leaks. In harsher winters, it can lead to ice dams. 

The freeze/thaw cycle is just one reason it’s important to inspect your roof for cracks and other existing damage before the temperatures drop. If your roof already has cracks, they will get worse with every freeze/thaw cycle.

If your roof has damage, if it’s old, or if you’re just not sure about its condition, it’s not too late to call Roofman for an inspection. We can inspect, repair, and even replace your roof year-round, even in winter!

Mild Winters Can Be Hard On Your Roof, Too!

Warm one day, cold the next. If you’ve lived in Michigan for long, you’re no stranger to temperature extremes. This winter has been especially mild so far with very little snow, and that’s mostly good news for your roof. Little to no snow means no snow load to stress your roof, and less chance of an ice dam forming. But that doesn’t mean a mild winter is easy on your roof.

When it rains or when snow melts, water runs down into seams and cracks in your roof. When the temperature drops and that water freezes, it expands, widening those seams or cracks slightly. It’s called the freeze/thaw cycle, and each time it happens, it can damage your roof a little bit more.
