Older Housing, Heavy Snow: The Middlesex County Case
Coastal snow is heavy with water, and a roof in Waltham can take a foot of it in a night. That pack is a full reservoir from the moment it lands, not something that becomes one slowly.
Older Middlesex County housing stock makes it worse. Shallow eave returns, knee-wall attics and additions built over unheated space all put warm air against a cold roof deck with very little insulation in between.
Ice-barrier practice in Middlesex County
Coastal Massachusetts jurisdictions generally require the membrane to extend past the interior wall line. On a house in Waltham with a deep overhang that is further up the roof than a single course.
What a Crew Does on a Waltham Roof
The first pass is assessment: eaves, valleys, gutter line and any interior staining, all photographed with timestamps. You see what the crew sees, and the rate and likely hours are agreed before work begins.
Steam then takes the dam off in sections, prioritizing wherever water is actively backing up behind it. The gutter trough and downspout are cleared through to daylight on the same visit, because a clear eave over a frozen gutter is a temporary fix.
Why the gutter has to be cleared in the same visit
A dam sitting above a gutter packed solid with ice is only half the problem. Clear the eave and leave the trough frozen, and the next day's meltwater has nowhere to run — it backs up onto the roof and the dam rebuilds from the bottom.
Crews steam the trough and the downspout through to daylight on the same visit. It adds time, which is why the hour estimate given on the phone accounts for it, and it is the difference between a fix and a repeat visit in Waltham the following week.
What the dam has already done to the gutter and fascia
Ice expands as it forms, and a trough packed solid pushes the gutter away from the fascia a little more every cycle. By the time the dam is thick enough to leak, the hangers are often pulled, the back of the trough has lifted, and the fascia board behind it has been wet for weeks.
None of that is visible until the ice is off. It gets photographed when it appears, because a bent gutter found in February is a great deal easier to argue about with a carrier than one discovered in May.
What steam actually does
A steam unit delivers water at roughly 290°F at a pressure low enough to rest your hand in the plume. It cuts a channel straight through the ice and lifts the dam off in sections, right down to the shingle. The heat does the work, not force, so granules, seal strips and flashing come through untouched.
That is the whole difference between steam and the hot pressure washers often sold as steam. A pressure washer cuts ice fast because of its pressure — and that same pressure strips the granules off asphalt shingles and drives water up under the courses. One method removes ice. The other removes ice and roof.

Middlesex County Coverage From Waltham
Crews working Waltham cover the adjoining communities on the same route — North Waltham, West Newton, Auburndale, Nonantum and Weston — so a storm week usually means one truck handling several addresses in Middlesex County rather than separate trips.
Nearest hub towns with their own crew pages: Newton, Lexington, Arlington, Cambridge, Medford, Somerville.
Scheduling for Waltham tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
If water is already inside a property in Waltham, call (888) 561-9664 rather than filling in a form — the phone is faster and leaks jump the line.
