Merrimack County sees the same pattern every winter: snow on the roof, warm air in the attic, and a line of ice building along the eave where the two meet. As part of our complete Franklin winter roof services, crews handle mold remediation across Merrimack County.
Franklin Ice Dams: What a Five-Month Snow Pack Does
A roof in Merrimack County spends most of the year's coldest months under continuous load. That is a different problem from a single heavy storm, and it produces a different kind of ice.

The ice that comes off a roof in Franklin in February is rarely one event's worth. It is a laminated record of the whole season, which is why it is thick, dense and firmly bonded to the shingle.
Ice-barrier practice in Merrimack County
In the colder New Hampshire jurisdictions the membrane requirement extends well up the roof plane rather than stopping at the first course, precisely because the ice here does not stay near the edge.
Mold Remediation in Franklin: How The Work Runs
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. Mold in the Attic After an Ice Dam.
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.
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 Franklin. Disturbing mold without it spreads spores to rooms that were clean.
The attic is the usual starting point
On most ice dam jobs in Franklin 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.
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.
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.
The clearance result goes into the claim file along with the before photographs, the removal photographs and the moisture log.

Neighborhoods and Towns We Reach From Franklin
Crews working Franklin cover the adjoining communities on the same route — Salisbury, Tilton, East Andover, Lochmere and Andover — so a storm week usually means one truck handling several addresses in Merrimack County rather than separate trips.
Nearest hub towns with their own mold remediation pages: Laconia, Concord, Goffstown, Manchester, Lebanon, Claremont.
During a cold snap Franklin gets worked alongside the neighboring Merrimack 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 Franklin often runs alongside water mitigation & dryout in Franklin, and both get written into one scope rather than billed as separate visits.
