Ice Dam & Roof Snow Removal in Tewksbury, MA

If you're searching for ice dam removal near you in Tewksbury, Billerica, or a neighboring town, here's the short version: an ice dam is a solvable problem if it's handled the right way, and a roof-and-ceiling problem if it isn't. Senco is based right here in Tewksbury, MA, and our crews clear ice dams and roof snow safely, every winter, without the shortcuts that damage shingles or make the leak worse.

What Is An Ice Dam?

Heat escaping through your attic warms the upper roof deck just enough to melt the snow sitting on it. That meltwater runs down the roof until it reaches the cold overhang above your gutters — where there's no heat underneath — and refreezes. Layer by layer, that refreezing builds a ridge of ice at the eave. The ridge is the "dam": it blocks the water behind it from draining off the roof, so it has nowhere to go but sideways and backward, under your shingles.

How Ice Dams Damage Your Roof

Shingles are built to shed water running downhill, not to hold back standing water. Once an ice dam forces meltwater uphill under the shingle line, it finds every seam, nail hole, and lap in the underlayment. From there it soaks the roof sheathing, saturates attic insulation, and shows up inside your house as a stained ceiling, a bubbled wall, or water at a window trim — often nowhere near where the dam actually formed. If an ice dam has already caused a leak inside your home, our team handles the interior damage the same way we handle any storm leak — see our roof leak repair page.

Roof Snow Load Risk On New England Colonials

A lot of homes in Tewksbury and Billerica are older colonials, framed to snow-load standards from decades ago. A couple of feet of wet, heavy New England snow adds real weight — especially where it drifts against a valley, a roof-to-wall transition, or a lower roof pitch below a taller one. Add an ice dam already sitting at the eaves, and that combined weight stresses rafters, sheathing, and gutters at the exact same edge of the roof. If your roof is sagging, groaning under load, or you're just not sure it's holding up, we'll take a look — and if the roof itself is aging out, our roof replacement page covers what that looks like.

How To Get Rid Of An Ice Dam

Four methods get tried every winter, and they are not equally safe on a cold roof. Here is what each one actually does.

Steam. This is what a contractor brings, and it's the only method that clears a dam in an afternoon without touching the shingles. Low pressure, hot water, melting a drainage channel straight down to the roof surface.

A roof rake. You can do this yourself, from the ground. Pulling snow off the bottom three or four feet of roof takes away the fuel the dam needs to keep growing. Stay on the ground, keep the pole well clear of the power line coming into the house, and stop before you find yourself reaching.

Calcium chloride. Slow, but it buys you time. Fill a leg of old pantyhose, then lay it across the dam so it runs from the roof toward the gutter, and it will melt a drain channel through the ice over a day or two. Check the bag says calcium chloride. Rock salt corrodes shingles, gutters, fasteners, and whatever is planted underneath.

Chipping at it. Hammers, hatchets, chisels, and pressure washers are how roofs end up with holes in them. The ice is frozen to the shingle, so it comes away with granules and sometimes whole tabs attached, and none of that shows until the spring thaw. If a crew offers to chip your dam off, that is the wrong crew.

If water is already coming through a ceiling, skip all of it and call us. Every hour that water sits inside the wall costs more than the removal does.

Safe, Steam-Based Ice Dam Removal

We remove ice dams with low-pressure steam, not axes, hammers, or rock salt. Steam melts a clean channel through the ice down to the shingle line, giving trapped water a path to drain off the roof — without chipping shingles, stripping granules, or driving more water underneath, which is exactly what happens with a pick or a bag of salt. It's slower than hacking at the ice, and it's the only method we consider safe for an asphalt shingle roof.

Roof Snow Removal

Where excess snow is adding weight or feeding the next ice dam, we clear it from the roof edges, valleys, and problem areas with roof-safe tools — never a shovel dragged straight across shingles. The goal is to reduce load and starve the next dam before it forms, not to strip the roof bare.

What Ice Dam Removal Costs

Three things set the price: how much ice is up there, how many sides of the house it is on, and how hard the roof is to reach safely in February. One dam over a garage is straightforward. A full perimeter on a two-story colonial after a week of freeze and thaw takes longer and takes more crew.

You get the number before we start, and it does not move once we are on the roof.

Call your insurer either way. Policies differ on whether they cover the removal, but interior water damage from an ice dam is often covered, and we will document what we find if you need it for a claim.

Preventing Ice Dams Before They Start

Removal solves the emergency; two things actually prevent the next one. First, attic insulation and ventilation — keeping the whole roof deck a consistent cold temperature so snow melts evenly (or not at all) instead of melting up top and refreezing at the eaves. Second, clear gutters and downspouts — a clogged gutter holds meltwater right where an ice dam already wants to form, making a bad situation worse. Clean, well-sealed gutters are one of the simplest ways to cut ice dam risk; see our seamless gutter installation page.

Heat cables come up a lot, and they are worth understanding before you buy any. Run along the eave in a zigzag, they keep a drain channel open so meltwater has an escape route. They do not stop the dam from forming, they cost money to run all winter, and they need replacing every few years. On a roof with an insulation or ventilation problem underneath, a heat cable treats the symptom and leaves the cause alone. Worth it on one stubborn trouble spot, not worth it as a whole-roof plan.
