Every Ketchikan 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 Ketchikan winter roof services, crews handle mold remediation 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.
Mold Remediation in Ketchikan: How The Work Runs
What it looks like from the homeowner side
Most people stay in the house. The affected room or attic is sealed off, the equipment runs for a few days, and the crew comes and goes through a zippered door in the containment. Mold in the Attic After an Ice Dam.
The noise is the air scrubbers and dehumidifiers running around the clock. Placement can usually be worked around bedrooms, and the timeline is set out before anything starts.
The smell is a symptom
A musty smell upstairs in winter, in a closet on an exterior wall, or coming out of a ceiling light usually means growth somewhere you cannot see, most often the attic or a wall cavity under the eave.
It is worth investigating rather than masking. Air fresheners and ozone machines do nothing about the growth or the moisture behind it.
Why ice dam water turns into mold
Ice dam water does not arrive like a burst pipe. It seeps in over days or weeks, into places nobody looks: the underside of the roof sheathing, the insulation along the eave, the top of an exterior wall. Those spaces are dark, they are full of wood and paper, and in winter they barely dry at all.
That is the whole recipe. Give mold a damp organic surface and a couple of days and it starts. The cold slows it down, the spring warm-up speeds it up, and by the time there is a musty smell upstairs it has usually been growing for weeks.
What comes out and what gets cleaned
Porous material that has grown mold, such as wet insulation, drywall paper and ceiling tile, cannot be reliably cleaned, so it comes out, bagged inside the containment.
Structural wood is different. Rafters, joists and sheathing with surface growth are HEPA vacuumed, cleaned and treated. Where the wood has gone soft or lost strength from repeated wetting, it gets cut out and replaced.
Remediation, then the rebuild, from one company
Removing mold is only half a job if you then have to find someone else to hang drywall, re-insulate and paint. Ice Dam Now does the interior repair as well: new insulation, drywall, texture, trim and paint, so the ceiling that came down to get the mold out goes back up under the same scope and the same claim.
That also means one set of photographs and moisture readings runs from the first visit to the finished room, which is what an adjuster wants to see.

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 mold remediation pages: Sitka, Juneau, Valdez, Girdwood, Palmer, Wasilla.
During a cold snap Ketchikan gets worked alongside the neighboring Ketchikan Gateway 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. Mold Remediation in Ketchikan often runs alongside water mitigation & dryout in Ketchikan, and both get written into one scope rather than billed as separate visits.
