Ice dams are not a Keene problem so much as a New Hampshire one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Keene winter roof services, crews handle mold remediation across Cheshire County.
Why a Keene Roof Dams Between Storms
Coastal snow is heavy with water, and a roof in Keene 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.
Retrofits often made it worse rather than better. Insulation laid on an attic floor without sealing the bypasses underneath it keeps the living space warm and sends the same warm air straight to the roof deck.
Ice-barrier practice in Cheshire County
In most coastal New Hampshire towns the eave membrane requirement extends past the interior wall line rather than stopping at the first course. On a roof in Keene with a deep overhang, that is further up than it sounds.
Mold Remediation in Keene: How The Work Runs
Clearance before the room is closed up
Before rebuild starts, the cleaned area is inspected again and, where appropriate, tested to confirm it is clear. Containment stays up until that point. Mold in the Attic After an Ice Dam.
The clearance result goes into the claim file along with the before photographs, the removal photographs and the moisture log.
Mold in the walls below an ice dam
Water that gets past the attic runs down the inside of exterior walls, wetting the top plate, the insulation in the stud bays and the back of the drywall. It is common to find growth inside a wall where the only visible sign was a faint stain at the ceiling line.
Those cavities get opened, the wet insulation and drywall come out, the studs are cleaned and dried, and the wall is rebuilt once readings are at standard.
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.
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.
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.
Interior repair by the same crews
Once the readings are at standard, the rebuild starts: new insulation to current R-value, drywall, tape, texture matched to the existing ceiling, trim and paint.
Doing the repair in-house keeps it in one scope and one claim, avoids the gap where a cleared room sits open waiting for another contractor, and keeps the documentation continuous from the first photo to the last coat of paint.

Keene Coverage and the Adjoining Communities
Crews working Keene cover the adjoining communities on the same route — Swanzey, West Swanzey, Marlborough, Sullivan and Spofford — so a storm week usually means one truck handling several addresses in Cheshire County rather than separate trips.
Nearest hub towns with their own mold remediation pages: Claremont, Goffstown, Bedford, Merrimack, Manchester, Concord.
Coverage runs across Keene and the nearby towns all winter, and capacity is surged into whichever New Hampshire market the storm actually hits.
Most jobs do not stop at one service. Mold Remediation in Keene often runs alongside water mitigation & dryout in Keene, and both get written into one scope rather than billed as separate visits.
