Ice dams are not a Ketchikan problem so much as an Alaska one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Ketchikan winter roof services, crews handle roof shoveling across Ketchikan Gateway County.
Why Ketchikan Roofs Dam Up: Altitude Sun on a Deep Pack
At Ketchikan'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.
Volume is the other factor. A Ketchikan Gateway County roof carrying several feet of pack has an enormous reservoir above an overhang that never sees direct sun, and the supply does not run out until spring.
Ice-barrier practice in Ketchikan Gateway County
Mountain jurisdictions across Ketchikan Gateway 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.
Roof Shoveling in Ketchikan: 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 Ketchikan lot that sometimes means carrying material to the street rather than dropping it, which costs hours and gets quoted that way.
How crews work without wrecking the roof
Plastic-bladed shovels only, never steel. Snow is cut and lifted in layers rather than scraped, and a cushion layer stays on the surface at all times so the blade never contacts shingle, membrane or seam. Discharge is aimed away from walkways, decks, shrubs and mechanical units.
Everyone on the roof is harnessed to a rated anchor. On an icy pitch that is not a formality — it is the whole reason this is not a homeowner job.
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 Ketchikan 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.
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 Ketchikan roof can look mostly clear from the street and still be carrying two feet of drifted pack in the valleys.
Metal roofs and sudden releases
A standing-seam or corrugated roof holds snow until it does not. Warmth from below lubricates the pan, and the whole slab can release at once - several hundred pounds arriving on a driveway, a deck, a parked car or whoever is under it.
Crews work metal from the ground wherever the pitch allows, clear and mark the drop zone first, and never put a person below a loaded panel. Snow guards get noted where they are missing, because a release will keep happening every winter until something holds it.

Where We Dispatch Around Ketchikan
Crews working Ketchikan cover the adjoining communities on the same route — Coffman Cove and Ward Cove — so a storm week usually means one truck handling several addresses in Ketchikan Gateway County rather than separate trips.
Nearest hub towns with their own roof shoveling pages: Sitka, Juneau, Valdez, Girdwood, Palmer, Wasilla.
Crews cover Ketchikan and the surrounding Ketchikan Gateway County towns through the whole season, and during a freeze event they run from first light until dark.
Most jobs do not stop at one service. Roof Shoveling in Ketchikan often runs alongside roof snow removal in Ketchikan, and both get written into one scope rather than billed as separate visits.
