Ice Dam Repair in Linden from $150. If the ceiling stains during a thaw rather than during rain, this is almost certainly what you have. Free inspection and a written quote.
On an overlaid post-war roof the ice-barrier question has a single honest answer: nobody added one during the overlay, because adding one means stripping the eaves. So if this is a recurring thaw leak in Linden, the conversation is about heat loss and ventilation rather than about the shingles on top.
An ice dam is a heat problem wearing a roofing costume. Warm air escaping into the roof space melts the snow lying on the upper roof. That meltwater runs down to the eaves, which are cold because nothing heated sits under them, and refreezes there. Repeat for a week and you have a ridge of ice holding water behind it.



The roofing element prices like any other repair, $350 to $1,800. But be clear about what you are buying: an ice dam is caused by heat escaping into the roof space, and the repair that ends it is air sealing, insulation and ventilation. That is not roofing, we do not pretend it is, and no published New Jersey figure for it exists to quote you honestly. Generally the cheapest place on this list: simple post-war roofs, driveways to work from and somewhere to put a ladder. The one thing that can move it is an existing overlay, which buries the eaves and limits what a repair down there can do.
The roof side: an ice barrier membrane at the eaves where the covering is coming off anyway, the damaged courses, and the flashing or valley the water has been getting past.
Insulation and air sealing work in the roof space, which is the part that actually stops the melting. We will tell you what needs doing and that it is somebody else's trade rather than inventing a number.
One winter, usually. That is a legitimate thing to buy if you are selling or if money is tight this year, and it should be sold as what it is rather than as a fix.
Post-war roofs are simpler to diagnose and cheaper to reach, so a Linden repair is usually a straightforward job -- but many of these roofs are now on their second covering, and a second covering hides the eaves detail. If the leak is at the eaves on an overlaid roof, the useful question is whether there is anything under the first three feet at all.
Including us. On repair work the checks are different from the ones people apply to a replacement, and cheaper to make.
The single most useful question on this page. A repair quoted from the roof alone is a repair quoted without knowing where the water traveled, and that is how a patch ends up in the wrong place. It costs nothing to ask and it separates most quotes immediately.
'Repair roof' is not a scope. 'Rebuild step flashing to the chimney, replace two vent boots, re-lap the valley' is -- and it can be checked when it is finished, which is the point.
Ask before, not after. A repair aimed at a named cause can be stood behind; a patch aimed at a stain cannot, and a contractor who is vague about the cause will be vague about this too.
Straightforward post-war roofs, easy access, and one specific complication: a lot of this stock is on its second covering.
Post-war roofs with simple geometry have fewer places to leak, which makes the ones that do fairly predictable: the vent boots, the bathroom stack and the junction with any later extension.
Flat sections in Linden are almost always over a later addition, and they are usually the newest roof on the property and the worst detailed.
Layer count is the first thing to establish on a Linden shingle roof, because a great deal of this stock has been overlaid once.
Post-war houses often have no chimney at all, so the equivalent detail here is the plumbing stack and the bathroom vent.
Easier access than most of this list -- driveways, frontages and somewhere to put a ladder -- which usually makes a Linden make-safe quick.
Pre-war chimneys, and eaves with no ice barrier.
Flat roofs behind parapets. Access is the first problem.
Low ground, open water. Which way is the water going?
Steep pitch. Specific details fail, not the field.
Rear additions and garages, and their junctions.
Built as a set, so the street is a reliable guide.
The widest age spread. Age decides where to look.
The questions that decide this job, answered up front.
We can clear it, and sometimes that is the right emergency step. But it will be back within the week, because the cause is heat escaping into the roof space and nothing about clearing ice changes that. Steam removal and chipping both risk the covering, and chipping frequently does real damage.
They can keep a channel open and stop water pooling behind a dam, which is a legitimate holding measure on a roof that cannot be improved this year. They do not stop the melting, they cost money to run every winter, and anybody selling them as the solution is selling a symptom.
Usually not. New Jersey treats repair or replacement of an existing roof covering on a DETACHED one- or two-family dwelling as ordinary maintenance under N.J.A.C. 5:23-2.7 -- no permit, no notice, no inspection. Attached houses, buildings with three or more units and anything structural are the exceptions, and we tell you which you are at the survey.
It is Florida Building Code, Existing Building, section 706.1.1: not more than 25 per cent of a roof area repaired, replaced or recovered in any twelve-month period unless the whole system is brought up to current code. It gets quoted nationally because it sounds universal. It is not New Jersey law, and it is not what decides whether your roof should be repaired.
Ask for the New Jersey HIC registration number and check it on the public register. Then ask whether they will look in the roof space, and whether the quote will name the cause rather than just the work. Those three questions cost nothing and they separate most of a shortlist immediately.
The roof space walked as well as the roof, before any price. The cause named in writing, not just the work.
