Ice Dam Repair in Stoneham from $300. A heat problem wearing a roofing costume. New shingles will not fix it. Free inspection and a written quote.
This is the worst combination in the service area for damming: capes with rooms in the roof, where there is very little space between the ceiling and the deck to get insulation and a ventilation path into. Honest advice here sometimes means saying the problem can be reduced rather than eliminated.
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. Access and staging appear as real lines on a hilly, tightly built lot. And where a cape has rooms in the roof, the ventilation work that stops it damming is a separate job from the covering -- priced separately, and worth doing.
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.
Hilly ground and close-set lots make access and staging a real part of the price rather than an afterthought, and the capes here frequently have rooms in the roof, which changes the ventilation picture completely and is the commonest cause of a dam that keeps coming back.
Where there are rooms in the roof, the roof is part of the heated building rather than a lid over a cold void, and it behaves differently every winter.
Worth knowing before you start ringing round, particularly if this started in February.
Wet heavy snow north of Boston does not blow off a roof -- it sits. The melt-refreeze cycle runs at the eaves for weeks, and the ceiling below reports the whole winter's work during the first proper thaw. Which is why the calls arrive in a cluster, in the same two weeks, right across the town at once.
Hilly ground and tight lots put access and staging into the price as a real line rather than an afterthought.
In a cape with finished rooms upstairs there is no attic to catch a leak and very little to inspect from inside.
Close-set lots on hilly ground mean shaded slopes and limited airflow, which is exactly what cedar does not want.
Shed dormers on capes create low-slope areas directly above living space, which is the least forgiving place to have one.
In a cape, most of what an inspection would normally look at is behind a finished ceiling.
We pull the permit. That is what keeps you eligible.

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.
For a standard asphalt roof on an average house, it is at the top of the range -- most Greater Boston single-family replacements land at $12,000 to $22,000. It is entirely reasonable for a large or steeply pitched house, a roof with a lot of dormers and valleys, or cedar shake at $12 to $20 a square foot. The number alone does not answer the question; what the quote itemizes does. If it does not break out area, tear-off, decking and the ice barrier, no figure can be judged.
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.
Yes in almost every municipality, and here is the part that matters far more than the answer: DO NOT PULL IT YOURSELF. Obtaining permits is the registered contractor's responsibility under M.G.L. c. 142A. A homeowner who pulls their own permit falls into the homeowner exemption, which disqualifies them from recourse under c. 142A and from the Guaranty Fund -- the fund that compensates eligible homeowners up to $25,000 toward unpaid judgments against a contractor. So when a roofer suggests it would be quicker if you pulled it, what is actually being proposed is that you give up your protection to save somebody an afternoon.
The HIC registration number on the paperwork, not just a website. A written contract, as this state requires over $1,000.
