Ice Dam Repair in Lynnfield from $300. A heat problem wearing a roofing costume. New shingles will not fix it. Free inspection and a written quote.
On a large house with several planes and an attached garage, dams form where the heated envelope meets the unheated one -- typically over the join between house and garage, or above a room built out into the roof. Those are the places to look first.
An ice dam forms when heat escaping into the roof space melts the underside of the snowpack, the meltwater runs down to the cold overhang beyond the heated building, and freezes there. The ridge of ice that builds holds the next lot of meltwater back until it finds a way under the courses -- which, on an old house with no ice barrier, it will.



Clearing a dam safely is generally $300 to $900 depending on access and how much of it there is. That stops the water. It does not stop the dam, because an ice dam is a heat problem rather than a roofing one, and the work that ends it is insulation, air sealing and ventilation. Bigger houses, more roof planes, and the only part of this service area where cedar at $12 to $20 a square foot is a live option rather than a theoretical one. Expect the quote to be built from details outward rather than from a rate.
More than the ceiling. Repeated damming works water under the courses at the eaves winter after winter, so a roof that dams every year is being aged prematurely from the bottom up.
Because the covering was rarely the cause. Plenty of people in this town have paid $15,000 or more for a roof that dammed again the following February, because the warm roof space and the cold eaves were never addressed.
Insulation carried properly to the wall plate, air leaks from the house sealed, soffit ventilation opened up, any fan discharging into the roof taken outside, and ice barrier that runs far enough up the slope to sit inside the heated envelope.
Larger houses mean larger roofs and more of them are complicated -- hips, dormers, attached garages and ells all on one building. Cedar shake turns up here more than anywhere else on this site, and cedar wants ventilation and sun, neither of which a wooded lot supplies.
This is the part of the service area where the cedar versus asphalt conversation is a real one rather than a theoretical one.
The first two are free, checkable, and worth $25,000 between them.
Past the wall plate, into the heated envelope -- not a token strip along the eaves. This is the detail that decides whether a new roof solves your winter problem or simply looks better while it continues.
Nobody knows how much deck has softened until the covering is off. A rate per sheet is honest; a lump sum gets revisited upwards once the roof is open.
If the roof has been damming, the covering was probably not the cause. A quote that replaces shingles and says nothing about the roof space is quoting for the symptom.
Bigger houses with more going on: hips, dormers, attached garages and ells all on one building, which means the price is built from details outward rather than from a square-foot rate.
On a large house with several roof planes, water can enter at one junction and appear below another entirely.
This is the real cedar territory on this site: larger houses, more open plots, and the kind of architecture cedar suits.
Flat sections on large houses are usually small, awkward and visible from somewhere -- a porch roof, a deck over a room, the flat behind a parapet on an ell.
On a large multi-plane roof every plane gets looked at rather than the one somebody is worried about, because they age at different rates depending on exposure.

What is worth knowing before you book this.
Usually not, and it is the most expensive misunderstanding in this market. A dam forms because heat escaping into the roof space melts the snow above it and the water refreezes at the cold overhang. New shingles change none of that. Plenty of people here have paid $15,000 or more and dammed again the next February.
No. Chipping takes granules and sometimes whole tabs off with it, and people fall doing it. Clearing is done carefully from a position that is safe to work from -- and it is a holding action either way, because the actual fix is insulation, air sealing and ventilation.
Not on age alone. Twenty years is well inside the normal service life of architectural asphalt and at the end of it for three-tab, so the first question is which you have. Then it is condition: granule loss, brittleness, how flat the covering lies, whether the deck is sound. North of Boston, add one more -- whether it has been damming. A roof with twenty winters of meltwater under its bottom courses is considerably older at the eaves than it is anywhere else, and that is where it will fail.
Rarely the full term in this climate. The rating describes the material under test conditions, not a roof on a particular house north of Boston. What shortens it here is the melt-refreeze cycle at the eaves, roof space ventilation, and how well the thing was nailed on day one. A 30 year product commonly gives 20 to 25 real years here, and a roof with proper ice barrier coverage and a working ventilation path will beat one without by several of them.
Nobody selling roofs is a neutral source on that, so here is what is known rather than a forecast. Roofing prices follow asphalt input costs, freight and local labor availability, and in this region they spike every spring because an entire winter's worth of damage gets reported in the same two weeks after the first real thaw. The practical consequence is not about the year -- it is that the cheapest time to replace a roof is when you choose to, and the most expensive is the month everybody else has decided at once.
The HIC registration number on the paperwork, not just a website. A written contract, as this state requires over $1,000.
