Longmont sits at the mouth of the St. Vrain corridor, which channels strong downslope wind and gives the city noticeably harsher wind events than towns just east of it.
Wind: St. Vrain canyon outflow produces some of the strongest sustained winds on the Front Range, and wind-related door damage is a routine Longmont call.
Hail: Boulder County hail is frequent and often large; Longmont neighborhoods see clustered panel damage.
Snow and ice: Heavy upslope snow loads doors and strains older springs. Regular winter thaw days with hard refreeze overnight.
Across Boulder County at 4,979 ft, these are the failures that fill our Longmont schedule: Wind-damaged and off-track doors; Hail panel damage; Undersized springs on mid-century garages; Older openers without battery backup during outages.
That list is not generic. It reflects Longmont's specific housing stock — Mid-century ranches with attached single-car garages; 1990s–2000s two-story homes; Newer east-side builds with three-car garages; Historic Old Town homes with detached garages.
Steady infill and east-side growth, with strong demand for insulated and wind-rated doors after repeated Front Range wind events.
We work throughout Longmont and the surrounding Boulder County, including the areas around Longs Peak views, Union Reservoir, St. Vrain Greenway, Downtown Main Street, Vance Brand Airport.
