Ice dams are not a Portola problem so much as a California one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Portola winter roof services, crews handle roof shoveling across Plumas County.
Elevation, Aspect and Ice: The Plumas County Pattern
At Portola's elevation the air can stay below freezing all day while direct sun still melts the top of the snowpack. That meltwater runs down under the pack, reaches a shaded eave, and refreezes — on a day the thermometer never rose above freezing.
Aspect decides which eaves suffer. A sunny plane sheds water across a roof in Portola 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 Plumas County
Snow retention above doors, walkways and parking is a requirement in most Plumas County jurisdictions for good reason: a release off a metal mountain roof is a serious event, not an inconvenience.
Roof Shoveling in Portola: How The Work Runs
What happens to the ground below
Several tons of snow has to land somewhere. Shrubs, railings, air conditioning condensers, downspout extensions, low roofs over porches and anything made of lattice are all easy to flatten with material coming off a roof above. Ceiling Sagging or Bulging After Snow.
The drop zones get chosen before the clear starts and anything fragile is either moved or worked around. On a tight Portola lot that sometimes means carrying material to the street rather than dropping it, which costs hours and gets quoted that way.
Clearing to let the drains work
On anything flat, the job is not finished when the snow is off. Drains, scuppers and overflow outlets have to be opened so the melt that follows has somewhere to go.
A cleared Portola deck with blocked drains just ponds and refreezes, and ponded water on a membrane finds seams.
Where hand clearing is the only option
A roof rake reaches the first several feet from the edge and nothing beyond it. Dead valleys between roof planes, the pockets behind dormers and chimneys, low-slope and flat sections, and upper roofs on anything over a story and a half all need someone on the roof with a shovel.
Those are also the places snow collects deepest, because wind deposits it there and nothing sheds it. A Portola roof can look mostly clear from the street and still be carrying two feet of drifted pack in the valleys.
Working around what is up there
Rooftop units, exhaust fans, conduit runs, gas lines, solar racking, skylights and safety railing all have to be cleared around rather than over. The drift shadow behind a unit is usually the deepest snow on the roof.
Skylights in particular get flagged and worked around deliberately — a shovel through cold glass is a bad afternoon for everyone.
Timing a clear against the forecast
Clearing a roof the day before eight more inches arrive is money spent twice. Clearing it the day before a thaw, or ahead of a rain-on-snow event, is money that prevents a claim.
Scheduling in Portola is built around the forecast rather than the order calls came in, and a job gets moved - with a reason - when the weather makes a different day obviously better.

Neighborhoods and Towns We Reach From Portola
Crews working Portola cover the adjoining communities on the same route — Beckwourth, Clio, Blairsden-graeagle and Calpine — so a storm week usually means one truck handling several addresses in Plumas County rather than separate trips.
Nearest hub towns with their own roof shoveling pages: Truckee, Tahoe City, Olympic Valley (Palisades), Nevada City, Grass Valley, South Lake Tahoe.
Portola sits inside the regular California service area, so a crew is usually scheduled the same day or the following morning.
Most jobs do not stop at one service. Roof Shoveling in Portola often runs alongside roof snow removal in Portola, and both get written into one scope rather than billed as separate visits.
