Winter is one of the best seasons to enjoy an outdoor sauna — but it also requires a bit of extra care. One critical maintenance step is making sure the sauna roof is cleared of snow on a regular basis.
Snow accumulation can become much heavier than most people expect. When snow mixes with ice or becomes wet and compacted, the weight increases dramatically. Under heavy snow conditions, it is possible for a roof to deform — or in extreme cases, even collapse — if the load is not removed in time.
Even a well-built sauna is designed with specific load limits. Leaving large amounts of snow and ice on the roof for extended periods puts unnecessary stress on the structure and roofing materials. This can lead to leaks, membrane damage, structural warping, and costly repairs.
Freeze–thaw cycles can also create ice layers that trap moisture and block proper drainage, further increasing weight and risk of damage.
Best practices for winter sauna care:
-
Inspect the roof after major snowfalls
-
Remove accumulated snow early before it compacts
-
Use a soft, non-metal tool to avoid damaging the roof surface
-
Avoid sharp shovels or aggressive scraping
-
Pay special attention when snow turns wet or icy
A few minutes of preventive maintenance can prevent serious damage and keep your sauna safe, strong, and ready to use all winter long.
