Every Big Bear Lake winter produces the same two calls: the ones who see the ice early, and the ones who see the ceiling stain first. As part of our complete Big Bear Lake winter roof services, crews handle ice dam removal across San Bernardino County.
Big Bear Lake Ice Dams: Melting on Days It Never Thaws
Altitude makes the sun stronger and the air colder at the same time. A roof in Big Bear Lake can be producing meltwater on its south face at midday while the thermometer reads well below freezing.
Depth makes it worse. A San Bernardino County roof can carry several feet of pack, and all of that is a reservoir sitting above an eave that never sees sun.
Ice-barrier practice in San Bernardino County
Design snow loads in San Bernardino County are among the highest anywhere, and the membrane and retention requirements that go with them are not formalities. On an older Big Bear Lake cabin or chalet neither may be present.
Ice Dam Removal in Big Bear Lake: How The Work Runs
Working at night and during an active storm
Freeze events do not keep office hours, and the worst leaks tend to announce themselves in the evening when the day's melt refreezes. Crews run lit, and a roof that is actively collecting snow is worked anyway, because waiting for better weather means the dam is bigger when somebody finally gets to it. Water Stain on the Ceiling in Winter.
What does stop a crew is wind and lightning. Both are judgment calls made on site in Big Bear Lake, and a postponed start gets explained rather than dressed up.
Dormers, valleys and dead spots
Ice does not distribute evenly. It concentrates where two roof planes meet, behind dormers, in dead valleys that drain nowhere, and along the north face that never sees sun. Those pockets hold water deepest and leak first.
A crew working a roof in Big Bear Lake clears the full eave line and then goes back through the valleys and dormer pockets specifically, because clearing the easy straight run and calling it done is how a roof leaks again a week later.
What the crew does on arrival
Before anything is touched, the crew walks the eaves, valleys and gutter line and photographs every dam and every point where water is tracking inside. You get shown what they found. Then the dam comes off in sections, starting wherever water is actively backing up, so drainage opens early rather than at the end.
Downspouts and gutter troughs get cleared in the same visit where they are frozen, because a dam removed above a solid block of ice in the gutter just reforms in the next cold night.
Why the dam formed in the first place
Ice dams are a heat problem wearing a weather costume. Warm air escaping into the attic melts snow on the upper roof; that meltwater runs to the eave, which hangs past the heated envelope and stays below freezing; it refreezes there, and the ridge of ice grows a layer every cycle. Removal is the emergency fix. Before the crew leaves you will know which part of your attic is feeding it.
Why salt and ice melt make it worse
Calcium chloride opens a narrow channel and leaves the dam standing. The channel refreezes, the dam does not go anywhere, and in the meantime the runoff corrodes gutter seams, fasteners, flashing and anything growing underneath.
It is a stopgap at best. On a roof in Big Bear Lake with an active leak it buys hours, not days, and it adds a corrosion problem to the water problem.

Where We Dispatch Around Big Bear Lake
Crews working Big Bear Lake cover the adjoining communities on the same route — Big Bear City, Fawnskin, Sugarloaf, Angelus Oaks and Green Valley Lake — so a storm week usually means one truck handling several addresses in San Bernardino County rather than separate trips.
Nearest hub towns with their own ice dam removal pages: Mammoth Lakes, June Lake, South Lake Tahoe, Placerville, Tahoe City, Olympic Valley (Palisades).
During a cold snap Big Bear Lake gets worked alongside the neighboring San Bernardino County towns on the same route, with active interior leaks moved to the front of the list.
Most jobs do not stop at one service. Ice Dam Removal in Big Bear Lake often runs alongside water mitigation & dryout in Big Bear Lake, and both get written into one scope rather than billed as separate visits.
