Ice Dam Repair in North Reading from $300. A heat problem wearing a roofing costume. New shingles will not fix it. Free inspection and a written quote.
Simple accessible roofs are the easiest to put right, because the roof space is usually open and reachable. Where a dam keeps forming on a straightforward colonial, the cause is very often one fixable thing -- a blocked soffit run, or a bathroom fan discharging into the roof instead of out of it.
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. Large simple roofs price accurately and cheaply per square foot. What costs money here is everything the canopy causes: valley clearing, gutter capacity, and slopes that stay damp long enough to need attention before their age would suggest.
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.
Large simple roofs under heavy tree cover, which is a specific combination: the roofs themselves are cheap to price accurately, and the debris in the valleys and gutters is what actually ages them.
Tree cover here is the variable rather than the architecture -- shaded slopes hold damp long after the sunlit ones have dried.
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.
Large, simple, accessible roofs on wooded lots -- the best combination there is for pricing a replacement accurately.
Under this much canopy the recurring repair is a valley, not a hole.
Heavy tree cover is the hardest condition there is for cedar.
A flat roof under mature trees is a debris trap, and a blocked outlet on a low-slope deck does not overflow harmlessly the way a gutter does -- it ponds until it finds a seam, and in January it freezes there.
Under this canopy the inspection pays attention to shaded slopes, valleys and gutter runs, because that is where a roof here ages first.
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.
Almost nobody in this trade quotes roofing by the hour, and you should be wary of one who offers to. Replacement work is priced by the square -- 100 square feet of roof area -- because the quantity is measurable and the risk of the job running long sits with the contractor rather than with you. Hourly pricing turns delays into your problem. Small repairs and diagnostic work are the exception and may carry a call-out or minimum charge, which should be stated up front.
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.
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.
The HIC registration number on the paperwork, not just a website. A written contract, as this state requires over $1,000.
