Quick Answer
A durable and waterproof roofing material such as corrugated metal or asphalt shingles is ideal for a root cellar, providing protection from the elements and extending the storage life of the root cellar's contents. These materials are also relatively low maintenance and can withstand the weight of snow.
Choosing the Right Roofing Material
When selecting a roofing material for a root cellar, consider the climate, budget, and desired level of maintenance. Corrugated metal roofing is a popular choice due to its durability and affordability. It can withstand heavy snow loads and is resistant to rot, mold, and mildew. Asphalt shingles are another option, offering a more traditional look and better wind resistance.
Considerations for Root Cellar Roofing
The root cellar’s roof should be designed to prevent water entry and maintain a consistent temperature. A minimum slope of 4:12 is recommended to ensure water runs off and doesn’t accumulate on the roof. Consider adding a waterproof underlayment to the roofing material to provide an extra layer of protection against leaks. For areas with heavy snowfall, consider using a roofing material with a high snow load rating, such as corrugated metal with a thickness of at least 26 gauge.
