The Freeze and Thaw Cycle

Freezing and Thawing Temperatures Aggravate Roof Issues

As winter weather shifts and temperatures begin to rise, these fluctuations can aggravate existing roofing issues. It’s common to encounter new leaks, largely as a result of the freeze/thaw cycle.

As temperatures rise, water makes its way into small cracks or holes in the roof. Then, when the thermometer drops again, the water freezes and expands, creating a void between the surrounding roofing materials. This allows more water to collect, continually growing and worsening the problem.

The Longer The Cycle Continues, The Worse The Damage Gets

This cycle affects all types of roofing systems, from shingles to membranes and metal. It can also affect any part of the roof that has collected moisture, including the gutters, decking, and insulation. Watch for changing coloration on your ceiling, which could alert you to a roof leak.

The freeze/thaw cycle can happen daily. Warm, sometimes sunny days, can be followed by colder overnight temps. The damage to your roof could spiral out of control quickly. Clear the snow away from around your gutters to help the melt run-off and prevent ice dams from forming under the snow.
