A roof in Massachusetts fails in ways a roof in a warm climate never will. It carries the weight of accumulated snow, it goes through freeze and thaw cycles dozens of times each winter, and it has to stop meltwater that is being pushed uphill under the shingles by an ice dam. We repair and replace asphalt, slate, rubber and flat roofs across Greater Boston, and we build for the winter rather than for the day the work is done.
Ice dams are the defining New England roofing problem, and they are misunderstood constantly. An ice dam is not caused by bad shingles. It is caused by heat escaping from the living space into the attic, melting the underside of the snowpack, and letting that water run down to the cold eave where it refreezes into a ridge. Water then backs up behind that ridge and finds its way under the shingles — which no shingle is designed to resist, because shingles shed water downhill and nothing more. That is why the real fix involves attic insulation, air sealing and ventilation as much as it involves the roof surface.
Freeze-thaw is the slower killer. Water gets into a hairline crack in flashing or a chimney mortar joint, freezes, expands, and makes the crack fractionally larger. Repeat that forty times a winter for a decade and a detail that looked fine becomes a leak. This is why chimney flashing, step flashing along dormers, and valley detail are where most Boston-area leaks actually originate, not in the middle of the field.
Boston has a great deal of old housing stock, and it comes with roofing specifics: slate roofs on Victorians that can be repaired rather than torn off, low-slope rubber roofs on triple-deckers that need entirely different treatment than pitched roofs, and complex multi-level roof lines with more valleys and penetrations than modern construction. We work on all of them and we will tell you when a hundred-year-old slate roof is worth another twenty years of targeted repair instead of a replacement quote.
We also handle the paperwork side. Massachusetts requires a licensed Construction Supervisor for structural roofing work, and most municipalities in the Greater Boston area require a permit for a full replacement. Some neighbourhoods add historic-district review on top of that. It is worth knowing before you start rather than after the material has been delivered.

- Experience with Boston-area housing stock: triple-deckers, Victorians, slate and complex roof lines
- Photographs of what we find before you get a quote, so nothing is taken on trust
- Serving Boston, Cambridge, Somerville, Quincy, Newton, Brookline, Medford, Malden and surrounding towns
- Reachable seven days a week, including during and after winter storms
What affects the cost
Roofing quotes in Massachusetts vary widely and for real reasons. What actually moves the number:
- Roof type — asphalt, slate, rubber and metal are very different jobs
- Square footage, pitch, and the number of valleys, dormers and chimney penetrations
- Condition of the deck beneath, which is often only visible once the old roof is off
- How much ice-and-water shield coverage the roof geometry and local code require
- Whether attic insulation and ventilation work is included to address ice dams properly
- Access and staging — a three-decker on a tight urban lot costs more to set up than a suburban ranch
- Permit and, in some neighbourhoods, historic district review requirements
- Season, since winter work is slower and more weather-dependent
Every quote is free and specific to your property — we do not price this kind of work over the phone without understanding what is actually there.

Frequently asked questions
What actually causes ice dams, and can a new roof stop them?
Ice dams are caused by heat escaping into the attic, melting the snowpack from below, and that meltwater refreezing at the cold eave. A new roof alone does not fix that. Ice-and-water shield along the eaves protects the roof from the water that does back up, which is essential, but the real cure is attic air sealing, insulation and ventilation. Any roofer who tells you shingles alone will solve it is not being straight with you.
Should I have snow removed from my roof?
Sometimes. Very heavy wet snow on a low-slope roof is a genuine load concern, and clearing the lower few feet of the roof can interrupt an ice dam. But roof raking done carelessly damages shingles, and getting on an icy roof is dangerous. If you are worried about the load on your roof, call and we will look at it rather than guess.
Can my old slate roof be repaired instead of replaced?
Very often, yes. Slate itself commonly outlasts the nails and flashing holding it, which means a roof that looks finished is sometimes a flashing and fastener job. We assess honestly. Replacing a serviceable slate roof with asphalt is a loss of both value and character, and we will say so.
Do you work on flat roofs on triple-deckers?
Yes, and it is a large part of what we do around Boston. Low-slope roofs fail at seams, drains, parapet walls and roof penetrations rather than in the middle. We repair and replace EPDM rubber, TPO and modified bitumen systems.
Can roofing work be done in winter in Massachusetts?
Emergency repairs, yes, and we do them. Full replacements are possible in cold weather but asphalt shingles need adequate temperature to seal properly, so the sealing sometimes completes when the weather warms. If your roof can safely wait for spring, we will tell you that instead of selling you a winter job.
Do I need a permit to replace my roof?
In most Greater Boston municipalities, yes, and Massachusetts requires a licensed Construction Supervisor for the work. Some neighbourhoods also fall under historic district review, which affects material choices. We handle the permit process and tell you up front if your property has additional requirements.
