Roof Repair in Union from $150. New Jersey repair prices, the cause found before the patch, and an honest answer when the cause is not the roof. Free inspection and a written quote.
Two roofs per property is normal here and the second one is the problem. An attached garage or a rear addition carries the oldest covering on the plot, gets looked at least, and joins the main roof at a junction that was made by somebody in a hurry decades ago.
Roof repairs in New Jersey run $350 to $1,800 for most jobs, with minor work from $150 to $600. Those are state figures. The reason the spread is that wide has almost nothing to do with the size of the hole and everything to do with whether anybody worked out what caused it.



Most New Jersey roof repairs land between $350 and $1,800, with minor work from $150 to $600. New Jersey sits above the national average on labor, so an online calculator will read low here. What moves a repair price is not the size of the hole, it is whether anybody established what caused it. The variable here is which roof. A repair to the house is priced normally; a repair to an attached garage or a rear addition often turns out to involve the deck as well, because nobody goes in there in winter and a leak runs unnoticed for weeks.
Calling at the first stain, an accessible roof, and a cause that is a single failed detail rather than a pattern. A straightforward flashing or a perished vent boot is at the bottom of every range on this page.
A leak that has already been patched, because now there is somebody else's work to undo. A steep roof needing staging. Wet decking. And a cause in the roof space rather than on the covering, which is a larger conversation.
If the same slope has been patched twice, we will say so rather than selling a third patch. A repair is worth its price when the covering around it still has life in it, and not otherwise.
The township north-west of the city, suburban in character and developed substantially after the war.
Detached and semi-detached single-family housing on proper plots, with attached garages and rear additions common.
Rear additions and attached garages are the recurring problem here, because the junction where an addition roof meets the original one is where water gets in. A garage roof is also the least-inspected roof on any property: it is usually the oldest covering on the plot and nobody notices until something stored under it is ruined.
A large share of the work on this site is second-time work, and the reason is almost always diagnosis rather than workmanship.
It enters at a junction -- a flashing, an upstand, a penetration, a lap -- then runs along the top of a rafter until it meets a low point and falls. On a shallow pitch that can be several feet from where it got in, so the wet ceiling is evidence of where the water ended up, not where it started.
Leaks in driving rain but not in vertical rain: an upstand or a lap. Leaks every time it rains: something genuinely open. Leaks during a thaw with no rain at all: an ice dam, and the covering above may be perfectly sound.
If the cause is heat escaping into the roof space, the fix is air sealing, insulation and ventilation. We will say so and write it down, rather than selling you a repair that buys one winter and comes back.
The classic Union ice dam is over an attached garage or a rear addition, because those roofs sit next to heated space on one side and unheated space below.
The junction between an addition and the original house is where most Union leaks start.
The flat roof in Union is typically over an attached garage, and it has a particular problem: nobody goes in there in winter, so a leak runs for weeks before it is noticed.
The shaded northern slope is the one to look at first on these plots, because mature planting around suburban houses keeps it damp for longer after every thaw.
Where a chimney sits at the junction of the house and an addition, there are two roofs and a masonry stack all meeting in one place.
If the water is coming into a garage or an addition rather than the house, say so -- it changes the urgency and what we bring.
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?
Post-war and often overlaid, so the eaves are buried.
Steep pitch. Specific details fail, not the field.
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.
Usually close, rarely exactly. Recent asphalt is widely available; older profiles and discontinued colors are not, and a new shingle never matches one that has had ten winters on it. Where a perfect match is impossible we take material from a low-visibility slope and put the near match there.
As long as the covering around it, if the repair was aimed at the right cause. That is the whole argument of this site: a good repair in a finished roof is money spent twice, and a good repair aimed at the wrong place fails whatever it cost.
Look away from the failure. If the covering across the rest of the slope still lies flat, still holds its granules and is not brittle, the roof has life in it and the repair is the right job. If the slope is generally spent, a repair is money spent twice. Then check the layer count: two coverings is the practical ceiling.
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.
Most New Jersey roof repairs run $350 to $1,800, with minor work from $150 to $600. A leak is usually $400 to $1,400 and a small isolated one $400 to $900. Flashing is $300 to $900, or $300 to $1,200 around a chimney, vent or skylight. New Jersey runs above the national average on labor, which is why online calculators read low.
The roof space walked as well as the roof, before any price. The cause named in writing, not just the work.
