Given the end of the season occurred in mid March, makes you wonder if they laid off workers and hence didn't stay on top of clearing snow from the roof for the last month when you're in a winter weather.
That was the first thing to occur to me as well. They're in a big snow year, but not the biggest ever. Snowpack at or near peak, no one doing any snow removal, or minimal at best. Data attached is from the Mission Creek snow station, 15-20 km north of BW and at 1780 m, slightly higher elevation than the village and similar aspect.
