The ice along a roof in Erieline is the symptom. The cause is warm air escaping into the attic, and it is still running right now. As part of our complete Erie winter roof services, crews handle commercial roof snow removal across Boulder County.
Sun on Cold Snow: The Erie Pattern
Thin air at altitude means intense direct sun even in deep cold. A Erie roof can be melting on its south face at midday in air that never gets near freezing, and all of that water has to go somewhere.

Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Erie to a shaded eave that has not been above freezing for weeks, and that is where the ice builds into a wall.
Ice-barrier practice in Boulder County
Mountain jurisdictions across Boulder County generally require ice-barrier membrane well up the roof plane, not just the first course, along with snow retention on metal roofs above entries and walkways.
Commercial Roof Snow Removal in Erie: How The Work Runs
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. Ceiling Sagging or Bulging After Snow.
Scraping a commercial Erie roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.
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.
The load reading is what makes that decision for you rather than a feeling about how deep the snow looks.
Mid-span is where the margin runs out
Long-span steel and open-web joist roofs carry least where the drift is deepest. The average depth across the field is not the number that matters; the depth over the longest unsupported span is.
That is where crews measure on an Erie building, and it is why two roofs with the same snowfall can be in very different trouble.
Drains and overflows come first
Before anything else comes off, the drains, scuppers and overflow outlets get opened. Otherwise the melt from the clearing has nowhere to go and the roof trades a snow problem for a ponding one.
On a deck in Erie with internal drains that means confirming flow below, not just clearing the grate.
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.

Boulder County Coverage From Erie
Crews working Erie cover the adjoining communities on the same route — Niwot, Frederick, Dacono, Firestone and Hygiene — so a storm week usually means one truck handling several addresses in Boulder County rather than separate trips.
Nearest hub towns with their own commercial snow pages: Lafayette, Louisville, Boulder, Longmont, Broomfield, Northglenn.
When a storm hits Boulder County, crews are dispatched by severity rather than by call order — water already inside the house goes first.
Most jobs do not stop at one service. Commercial Snow in Erie often runs alongside crane-assisted snow removal in Erie, and both get written into one scope rather than billed as separate visits.
