Ice dam restoration involves mitigating and repairing interior water damage caused by ice dams — ice formations at roof edges that trap melting snow water, forcing it under shingles and into the building envelope. The scope includes water extraction, structural drying, drywall and insulation removal, and in some cases roofing and insulation remediation — with specific scope items that are frequently missed by restoration companies unfamiliar with the job type.
In northern markets, winter storm season is either a growth event or a chaos event, depending on how prepared your company is. A single significant ice event can produce 50–100 new jobs in 72 hours. Prepared restoration companies staff up, mobilize fast, and execute profitably. Unprepared ones chase calls at margins they haven’t calculated.
Ice dams form when heat escaping from the building warms the roof deck, melting snow above. Melt water runs to the cold eave overhang, refreezes, and water backs up under shingles into the building envelope. Where it goes determines the scope: attic insulation (saturated batt insulation typically must be removed), attic structure (moisture content must be measured and monitored), interior ceilings and walls (the moisture migration path must be traced with moisture meters), and window wells and exterior walls (ice dam water frequently runs along exterior walls before finding entry points).
(1) Attic access and working conditions — cold temperatures, low clearance, and insulation make attic work significantly more time-consuming than office assumptions. (2) Full attic insulation removal and replacement — code-required R-values, air sealing at penetrations, and thermal bypass correction all add scope. (3) Mold assessment timeline — ice dam damage discovered weeks or months later may have supporting mold growth; every job should include an attic mold assessment. (4) Exterior damage documentation — document roofing, gutters, and fascia before any exterior work to establish pre-existing condition. (5) Thermal imaging — identifies moisture migration paths that moisture meters alone miss; a legitimate scope item that supports adjuster documentation.
Ice dam damage is typically covered under homeowners’ insurance as sudden and accidental water damage. Coverage varies — some policies exclude the cost of ice dam removal itself (roofing work) while covering the interior water damage restoration. Confirm coverage with the carrier before committing scope.
Ice dam removal is the roofing trade work of removing the ice formation — typically performed by a roofer using heat cables, steam lancing, or mechanical methods. Ice dam damage restoration is the interior water damage mitigation and structural restoration performed by a restoration contractor. These are typically separate scopes performed by different contractors.
Yes. Attic moisture from ice dam intrusion, if not properly mitigated, creates conditions that support mold growth. The combination of organic material, moisture, and the temperature ranges typical of northern building envelopes in winter are all conducive to mold development.
