What is Ideal Shape for a Quinzhee Roof?

Designing the Quinzhee Roof

When building a quinzhee, it’s essential to create a stable and waterproof roof. The ideal shape for a quinzhee roof is slightly convex, with the highest point in the center. This curvature helps to redistribute the weight of the snow and prevents it from accumulating in one spot and causing collapse.

Measuring the Roof Slope

To achieve the right slope, use a string and stakes to create a diagonal line from the top of the quinzhee to the ground. Measure the angle of this line using a protractor or a clinometer. A slope of 30-40 degrees is ideal for a quinzhee roof, as it allows snow to slide off and prevents water from seeping in. You can also use a technique called “the two-stake method,” where you drive two stakes into the ground, one on either side of the quinzhee, and tie a string between them. This will help you to create a consistent slope and ensure that the roof is even.

Shaping the Roof

To shape the roof, start by packing the snow down with your feet or a shovel. Then, use a long, flat tool, such as a snowboard or a large piece of plywood, to shape the roof into a convex curve. Start at the center of the quinzhee and work your way outwards, applying even pressure to create a smooth, curved surface. Be careful not to apply too much pressure, as this can cause the roof to collapse. Once you’ve shaped the roof, use a shovel or a snowboard to create a slight overhang around the edges, which will help to prevent snow from accumulating and causing the roof to collapse.
