Ice Dam Removal Near Greater Boston

If you can see a ridge of ice hanging off your eaves, you already have a leak in progress, not just an ugly icicle. That ridge blocks meltwater from draining off the roof, and the water backs up under the shingles looking for a way in. It doesn’t need to be dripping in your kitchen yet for the damage to be underway inside the wall.

How a dam forms

An ice dam forms when the upper part of your roof sits above freezing while the eaves stay below it. Snow melts higher up, runs down, and refreezes the moment it hits the cold edge. Heat escaping from the house into the attic is the usual reason the roof warms unevenly like that. A run of direct sun on an otherwise cold roof can add to it too. Either way, once water is ponding behind that ice, it can travel sideways and upward under the shingles, well past the edge you can see from the ground. It shows up in valleys and around chimneys too, not just at a straight eave line. Left alone, trapped water in the sheathing and insulation turns into the kind of damp that grows mold, and the drywall repair costs more than the roof work would have.

The steam visit, and what it is not

This is not a project for a homeowner with a garden hose and a Saturday afternoon, and it is not a job to do from the roof yourself. Please do not climb up on a snow or ice covered roof to deal with this. KMK Roofing uses low-pressure steam to melt a channel through the ice so water can drain again. That is the method that works without wrecking the roof. Cold shingles are brittle. A hammer or chisel cracks them. A salt line eats the granules and the gutters underneath it. A pressure washer does both, plus it can drive water further under the shingles than the ice dam already did. Steam melts the ice without hitting the roof deck with force, which is the whole point of bringing in someone with the right equipment instead of tackling it yourself.

What actually stops it from coming back

Clearing the ice gets the water moving again this week. It does not change the reason the dam formed in the first place, which is heat escaping into the attic and warming the underside of the roof deck. That’s an attic problem, not a roof-edge problem, and it usually means looking at air leaks around fixtures, ductwork, and the attic floor before anything else. If you’re seeing the same dam every winter, the fix isn’t more steam visits, it’s an attic ventilation assessment.

Not a snow removal job

Ice dam removal and roof snow removal solve two different problems, even though a heavy snow year makes them show up together. Taking snow off the roof reduces the meltwater feeding a dam and eases the load on the structure, but it’s a separate visit with separate tools, and it doesn’t reopen drainage once an ice ridge has already formed at the eave. If your roof is carrying a heavy load and you’re not sure which call to make, just contact us and we’ll tell you which one you actually need.
