Homeowners across Bonneville County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Ammon winter roof services, crews handle commercial ice dam removal across Bonneville County.
Why Ammon Roofs Dam on Days It Never Thaws
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 Bonneville County
Design snow loads up here are among the highest in the country, and the membrane and retention details that come with them are not paperwork. On an older Ammon cabin neither is likely to be present.
Commercial Ice Dam Removal in Ammon: How The Work Runs
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
Multiple buildings on one site
Campuses, retail strips and multi-building properties get walked together and prioritized by which deck is closest to trouble, rather than worked in the order the calls came in.
One scope, one invoice, one contact. It is a meaningfully different job from nine separate ones.
Internal drains fail differently from gutters
A residential gutter overflows when it blocks. An internal roof drain just stops, and the water stays on the deck at depth until it finds a seam, a flashing detail or a pitch pocket.
Crews open the drain throat and then confirm flow in the leader below before calling it clear. An open drain over a frozen leader is not an open drain, and on an Ammon building that distinction shows up as a tenant ceiling two floors down.
Parapets hold the water in
A parapet is why a commercial deck ponds instead of shedding. Scuppers through the parapet are the only exit, and they are narrow, exposed on three sides and the first thing to freeze solid.
Steaming a scupper throat open is often the single highest-value twenty minutes of a commercial Ammon call.
The pitched sections nobody plans for
Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.
Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.

Neighborhoods and Towns We Reach From Ammon
Crews working Ammon cover the adjoining communities on the same route — Iona, Ucon and Shelley — so a storm week usually means one truck handling several addresses in Bonneville County rather than separate trips.
Nearest hub towns with their own commercial ice dams pages: Idaho Falls, Rexburg, Driggs, Pocatello, Sun Valley, Ketchum.
Ammon sits inside the regular Idaho service area, so a crew is usually scheduled the same day or the following morning.
Most jobs do not stop at one service. Commercial Ice Dams in Ammon often runs alongside commercial roof snow removal in Ammon, and both get written into one scope rather than billed as separate visits.
