Ice dams are not a Valdez problem so much as an Alaska one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Valdez winter roof services, crews handle commercial roof snow removal across Valdez Cordova County.
Why Valdez Roofs Dam Up: Altitude Sun on a Deep Pack
Mountain ice dams are a solar problem more than a temperature one. The sun works the pack from above while the air stays cold, so meltwater is produced and refrozen within the same afternoon.

That is why mountain roofs dam up on clear, cold weeks that look harmless. South and west faces melt, north-facing eaves and shaded valleys hold the ice, and the pack above keeps feeding it.
Ice-barrier practice in Valdez Cordova County
High-country Alaska codes typically call for extended ice barrier and, on metal roofing, snow guards above any door, walkway or parking area. Both exist because of what comes off these roofs.
Commercial Roof Snow Removal in Valdez: How The Work Runs
The cost of a shutdown against the cost of a clear
Clearing a large deck is a real number and it is easy to defer. The comparison that matters is not clearing against nothing, it is clearing against the day the building is closed while an engineer inspects it - lost trade, displaced tenants, and an insurer asking what was done beforehand. Ceiling Sagging or Bulging After Snow.
The load reading is what makes that decision for you rather than a feeling about how deep the snow looks.
Why large decks carry the most risk
A long-span steel or open-web joist roof has the least margin exactly where the drift is deepest — mid-span. Snow does not settle evenly either: it piles against parapets, behind rooftop units, in the lee of higher adjoining roofs, and in valleys between bays. The average depth across the roof is not the number that matters.
Crews survey depth and density at the drift points rather than the middle of the field, and calculate the working load from that against the structure's design capacity.
Reduction to a threshold, not a bare deck
The goal is bringing the load under the structure's capacity safely, with a cushion layer left on the membrane throughout.
Scraping a commercial Valdez roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.
Ponding after the clear
Taking the snow off a flat roof with frozen drains leaves meltwater with nowhere to go, and water that ponds and refreezes puts load back on a deck that was just relieved.
So drains and overflows are opened as part of the clear rather than afterwards, and the roof is left draining. A clear that stops at the snow is half a job.
What the documentation covers
Depth and density readings, calculated load, dated photographs and a written condition report per visit.
Preventing an imminent failure is treated as loss mitigation by most carriers, and that record is what supports the position if it is ever tested.

Nearest hub towns with their own commercial snow pages: Girdwood, Palmer, Wasilla, Anchorage, Soldotna, Kenai.
Crews cover Valdez and the surrounding Valdez Cordova County towns through the whole season, and during a freeze event they run from first light until dark.
Most jobs do not stop at one service. Commercial Snow in Valdez often runs alongside crane-assisted snow removal in Valdez, and both get written into one scope rather than billed as separate visits.
