Homeowners across Blair County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Altoona winter roof services, crews handle mold remediation across Blair County.
Wet Snow, Swinging Air: Altoona Ice Dams
Coastal snow is heavy with water, and a roof in Altoona can take a foot of it in a night. That pack is a full reservoir from the moment it lands, not something that becomes one slowly.

Older Blair County housing stock makes it worse. Shallow eave returns, knee-wall attics and additions built over unheated space all put warm air against a cold roof deck with very little insulation in between.
Ice-barrier practice in Blair County
Historic district review in parts of Blair County adds a step on materials and sometimes on color, which is worth knowing before a re-roof is scheduled rather than after the permit is refused.
Mold Remediation in Altoona: How The Work Runs
Attic mold: the sheathing, the rafters and the insulation
Most ice dam mold is in the attic. Meltwater backs up under the shingles at the eave, wets the roof deck from above, and runs down onto the insulation. Black spotting on the underside of the OSB or plywood along the eave line, darkened rafters and matted, stained insulation are the signs. Mold in the Attic After an Ice Dam.
Wet insulation comes out and is bagged inside the containment. Affected sheathing and framing are HEPA vacuumed, cleaned and treated, or cut out and replaced where the wood has lost strength. Then the attic is dried to a measured number before anything goes back in.
The attic is the usual starting point
On most ice dam jobs in Altoona the worst growth is on the underside of the roof deck in the first few feet above the eave, exactly where the meltwater backed up. It often looks like a band of dark spotting running along the eave line.
Insulation along the same line is usually matted and stained. Both come into the scope together, because drying the deck while leaving wet insulation against it does not work.
Why drying comes before rebuilding
Closing up a wall or ceiling over damp framing is how mold comes back. Air movers and dehumidifiers run until moisture readings on the framing and sheathing reach a dry standard for that material.
Only then does insulation and drywall go back in. In an Altoona winter, with cold cavities, that can take longer than people expect, and the daily readings show exactly where it is up to.
Containment and negative air
Before anything moldy is disturbed, the work area gets sealed off with poly sheeting and put under negative air pressure with an HEPA air scrubber exhausting it. Air flows into the work area, not out of it.
That is the step that keeps a contained attic or ceiling problem from becoming a whole-house problem in Altoona. Disturbing mold without it spreads spores to rooms that were clean.
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.
