Salt Lake City roofs face a winter challenge shaped by the mountains: heavy snow and the ice dams that follow. For homeowners in Federal Heights, Holladay, The Avenues, and the canyon-adjacent neighborhoods, understanding both is the key to a dry winter.
Snow load
Foothill and canyon-adjacent homes accumulate real snow load over a Wasatch winter. A sound roof structure, proper materials, and good drainage handle it; problems show up on under-built additions and older roofs. Standing-seam metal sheds snow well, which reduces load and ice-dam risk — though snow guards should be planned so a sudden snow slide doesn't damage landscaping, gutters, or people below.
How ice dams form
Attic heat melts snow on the upper roof; the water runs to the cold eaves and refreezes, building a ridge of ice. Water then pools behind the dam and backs up under the roofing into the home. Older Salt Lake homes with minimal attic insulation and ventilation are especially prone.
The real fix is the attic
Keeping the roof deck cold prevents dams. Air-seal and insulate the attic floor so heat stays in the house, and provide balanced intake and exhaust ventilation. During any re-roof, ice-and-water membrane at the eaves and valleys is the backup layer that keeps backed-up water out.
Don't attack the ice
Chipping at an ice dam damages the roof. Address active leaks and then fix the root cause — insulation, ventilation, and eave protection — before the next storm cycle.

Frequently Asked Questions
Why do Salt Lake City roofs get ice dams?
Heat escaping into the attic melts snow on the upper roof; the meltwater refreezes at the cold eaves and builds an ice dam that backs water up under the roofing. Foothill and canyon-adjacent homes with heavy snow and older attics are most prone.
Does metal roofing help with snow?
Yes. Standing-seam metal sheds snow readily and resists ice dams, which is why it's popular in the Salt Lake foothills — though snow-guard placement should be planned so shedding snow doesn't damage what's below.
