Chimney Flashing Repair in Union: what actually fails

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. That is the hardest detail on a suburban roof to get right and the most common place on a Union property for water to come in.

Standard roof flashing repairs run $300 to $900 in New Jersey, and flashing around a chimney, vent or skylight is $300 to $1,200. On pre-war housing with masonry chimneys this is the single most common leak there is, because a chimney is a structure moving independently of the roof it passes through.

  • The addition-to-house junction, where most leaks start
  • The garage roof, which is the oldest covering on the plot
  • Deck condition under any flat section nobody visits
  • The shaded slope, which ages ahead of the sunlit one

Chimney flashing repair cost in Union

Standard roof flashing repairs are $300 to $900 in New Jersey; flashing around a chimney, vent or skylight runs $300 to $1,200. On pre-war housing with masonry stacks this is the most common leak there is, because a chimney moves independently of the roof it passes through. 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.

01

Rebuild, not seal

Sealant over a failed flashing is a lid on the problem. It looks like work, costs less and lasts a season. Rebuilding the step and counter-flashing costs more and ends it.

02

What makes it cost more

A stack in a valley or at a junction between two roofs. A back gutter that was never installed. And masonry that has to be made good before metal can be let into it.

03

When it is not our job at all

A cracked crown, a failed liner or open pointing are masonry. If that is what is letting water in we will tell you, because flashing over failing masonry is work that looks like a repair and is not one.

Roofs in Union, and what that means for chimney flashing repair

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.

Before you choose

Four questions worth asking anybody who quotes a repair

Including us. On repair work the checks are different from the ones people apply to a replacement, and cheaper to make.

01

Did anybody go into the roof space

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.

02

Does the quote name the cause, not just the work

'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.

03

What happens if it leaks again

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.

Questions

The questions that decide this job, answered up front.

Questions

What homeowners here ask

Why does the leak come back after sealing around the chimney?

Because sealant is not a flashing. A chimney moves independently of the roof it passes through, so anything relying on adhesion across that joint fails within a season or two. The repair that lasts rebuilds the step flashing and lets counter-flashing into the masonry joint.

How do I know if it is the flashing or the chimney itself?

From where the damp is and what the masonry looks like. A cracked crown, open pointing or a failed liner put water inside the stack and it shows up lower down, often in a different pattern from a flashing leak. We will tell you which one you have, and masonry is not our trade.

Should I repair or replace?

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.

How do I find a reputable roofer?

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.

How much does it cost to repair a roof in New Jersey?

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.
