Snow can not only damage your exterior siding but it can cause extensive leaks causing even more interior damage. The reason why snow is not good for your exterior siding or roofing shingles is because the builds up against the exterior envelope and then slowly melts. Leaks like this can reach areas much higher than typical rain. Products like James HardiePlank Fiber Cement is incredible durable but the engineers still do not like water and snow resting on their product. A cut piece of Fiber Cement is prone to swelling vs factor sealed cut and primed edge. It will take many years for fiber cement to break down in moisture but will last a lifetime with proper maintenance.

Wood siding in the snow is a terrible idea. The snow builds up and then slowly melts creating more time for the wood siding to be saturated in water. This causes dry rot and structure damage much quicker.

Vinyl siding gets cold and brittle and can easily crack or get damaged. Vinyl siding also is an excellent insulator for your home.

Snow might not be as frequent in the Pacific Northwest compared to other regions, but when it does occur, it can pose several risks to siding, especially if the siding isn’t properly installed or maintained. Here are some potential dangers:

  1. Water Damage: Snow can melt and seep into the siding, especially if there are gaps or cracks. This can lead to water damage, rot, and mold growth over time.
  2. Freeze-Thaw Cycles: In areas where temperatures fluctuate around freezing, snow melting during the day can seep into small cracks in the siding. When temperatures drop again at night, this water can freeze, causing the cracks to expand and potentially damaging the siding further.
  3. Weight: Heavy snow accumulation can put significant weight and pressure on siding, especially if it’s already weakened or compromised. This can lead to warping, bending, or even cracking of the siding material.
  4. Ice Dams: In colder climates, snow melting on the roof can refreeze at the eaves, creating ice dams. These dams can force water under the shingles and eventually into the siding, causing damage.
  5. Impact Damage: Snowfall combined with strong winds can propel snow and ice against siding with significant force, causing dents, scratches, or even punctures.
  6. Mold and Mildew Growth: Snowmelt that seeps into siding can create a moist environment perfect for mold and mildew growth, which not only damages the siding but can also pose health risks.

To mitigate these risks, it’s essential to ensure that siding is properly installed, sealed, and maintained. Regular inspections can help identify any areas of concern before they become significant issues. Additionally, proper insulation and ventilation in the attic can help prevent ice dams, reducing the risk of water damage to the siding.
