Quick Answer
To address moisture issues inside a tree well shelter, use a waterproof tarp to cover the top and sides, ensure good ventilation through a hole or gap, and install a roof that allows snow to slide off while keeping rain out. This will help reduce condensation and prevent water accumulation.
Waterproofing the Shelter
When building a tree well shelter, ensure that the waterproof tarp is securely fastened to the tree with ropes or clips, and that the edges are tucked under a few inches of snow or dirt to prevent water from seeping underneath. Use a waterproof sealant to seal any gaps or holes around the tarp, and consider adding a plastic or metal sheet to cover the entrance to prevent snow from coming in.
Ventilation and Snow Removal
Adequate ventilation is crucial in a tree well shelter to prevent moisture buildup and reduce the risk of mold and mildew. Drill a hole or create a gap in the tarp to allow stale air to escape, and ensure that the shelter has a slight overhang to allow snow to slide off. To prevent snow from accumulating inside the shelter, use a snow rake or shovel to clear the entrance and interior regularly.
Roofing and Snow Load Management
A roof that allows snow to slide off while keeping rain out can be achieved by using a slightly pitched design or a corrugated metal roof. Ensure that the roof is securely attached to the tree and that the tree can support the weight of the roof and accumulated snow. Consider adding a snow load management system, such as a snow fence or a snow weight-rated roof, to prevent the roof from collapsing under the weight of heavy snowfall.
