Storm Damage Guide: Ice Dam Prevention After Severe Weather in Newmarket
Here's how Newmarket homeowners actually approach ice dam prevention in 2026, based on what our field crews see every week. Deeper freeze depths mean liner condensation and cap ice-loading. Below: what to expect, real numbers, and the questions worth asking before you book.
Quick answer
The three signs Newmarket homeowners keep missing on ice dam prevention: smell changes, staining above the firebox, and unusual sound. Any one means schedule; two together means stop-use.
Typical
$352–$564
Duration
3–5 hrs
Freeze-thaw
70/yr
The 90-second self-check
Look at the cap for gap or crushing, walk the crown for hairline cracks (70 freeze-thaw days a year here will find any weakness), and shine a light up the flue for glazing. Photograph anything unclear and text it over.
When to stop using the appliance
Any active water ingress, visible flame licking outside the firebox opening, or the smell of gas products in the room means shut down and call. Insurance coverage on damage during "known unsafe operation" is thin.
Signs the ice dam prevention can't wait
The most reliable early warnings on Newmarket homes: smell changes near the appliance, staining above the firebox or on interior ceilings, unusual soot at the cap, and any water inside the smoke chamber. Any one of these is a call — two together is a stop-use.
