Structural Snow Loads in Nikiski

Calculating truss dimensions and roof pitch guidelines for heavy winters in Nikiski.

Truss Load Calculations

Nikiski receives heavy winter snow. Roof systems are engineered for 50-70 lbs per square foot, utilizing double-plated spruce trusses.

Ventilation and Ice Dam Prevention

Heat leakage warms the roof, melting snow that refreezes at the gutters. Continuous soffit-to-ridge venting keeps the attic cold, stopping ice dams.
