Ice Dam Repair in Wilmington from $300. A heat problem wearing a roofing costume. New shingles will not fix it. Free inspection and a written quote.
Streets of similar post-war houses give a useful test: if some dam and others do not, the roofs are the same, so the difference is what has been done inside them since. Added insulation, converted attics and new bathroom fans are the usual suspects.
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. The most predictable pricing here. Simple shapes and good access mean the variables are visible: the layer count, and whether you are being quoted architectural at $6.75 to $11.50 or three-tab nearer $3.50 for a similar-looking total.
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.
The most straightforward roofing in this service area and the easiest to price honestly: moderate pitches, good access, little geometry. The variables are age and layer count, and two coverings is the ceiling before a tear-off stops being optional.
Simple roofs are where the difference between an architectural and a three-tab quote shows up most plainly, because nothing else in the price is complicated.
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.
The most straightforward replacement work in this service area -- moderate pitches, good access, little geometry.
Simple roofs fail simply, which is good news for a repair: a lifted course, a split pipe boot, a nail line backing out.
Post-war houses here were mostly built for asphalt, so cedar is a deliberate upgrade rather than a restoration.
Post-war attached garages and rear additions, generally large and easy to reach, which keeps this work cheap and predictable.
On simple post-war roofs an inspection answers two questions quickly: how many coverings are up there and how much life the top one has left.
We pull the permit. That is what keeps you eligible.
Lakeside and Victorian. Details, not area.
Big simple roofs under a lot of trees.
Large houses, complicated roofs, real cedar country.
Hilly, tight, and full of capes with rooms in the roof.
A city: every building type within one mile.
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.
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.
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.
It is a Florida rule and it has no force in Massachusetts. The 25% rule comes from the Florida Building Code Existing Building, where repairing or replacing more than a quarter of a roof within a year can require the whole roof to be brought up to current code. Massachusetts has no equivalent provision -- what governs here is the state building code and your own municipality's permitting. It turns up in searches because national content repeats it without saying which state it belongs to.
The HIC registration number on the paperwork, not just a website. A written contract, as this state requires over $1,000.
