How Cold Weather Can Damage Roofing

Oct 26, 2023

Cold weather, while a sign of festive times and cozy evenings, can also spell trouble for your roofing system. Fluctuating temperatures, snow accumulation, and icy conditions can cause a multitude of problems that affect the integrity of your roof. In this Cloud Roofing blog post, we explore how cold weather can impact your roofing and underscore the importance of routine maintenance and prompt repairs.

Ice Dams

  • Formation: Ice dams occur when snow on the roof melts, flows down, and refreezes at the eaves. This forms a ridge of ice that prevents subsequent meltwater from draining off the roof.
  • Implications: The trapped water can seep beneath shingles, causing leaks, damaging the roof structure, and potentially affecting the interiors of your home.

Freeze-Thaw Cycles

  • Process: With temperatures oscillating around the freezing point, water can enter tiny cracks in the roof during the day and freeze at night, expanding the cracks.
  • Implications: Over time, repeated freeze-thaw cycles can widen these fissures, leading to significant damage to shingles, tiles, or other roofing materials.

Snow Accumulation

  • Weight Concerns: Accumulated snow, especially the wet and heavy kind, can exert significant pressure on your roof.
  • Implications: The added weight can strain the roof structure, potentially leading to sagging or, in extreme cases, collapse.

Icicle Formation

  • Causes: Icicles often form from the same conditions that lead to ice dams - melting snow and re-freezing at the roof's edge.
  • Implications: Apart from being a potential hazard if they fall, icicles can also indicate poor roof insulation or ventilation. Persistent icicles can damage gutters and roofing over time.

Reduced Flexibility of Materials

  • Material Behavior: Roofing materials, particularly asphalt shingles, become more brittle in cold temperatures.
  • Implications: Brittle materials are more susceptible to cracks and breaks, especially if burdened by snow or walked upon. This can lead to exposure of the underlying layers and potential leaks.


  • Formation: When warm indoor air meets a cold roof, condensation can form.
  • Implications: Over time, this moisture can lead to mold, mildew, and rot, compromising the roof's structural integrity and the home's air quality.
