Chimney Flashing Repair in Midtown: what actually fails

On commercial and mixed-use buildings the penetration through a flat roof is usually not a chimney but a flue, a duct or a vent, and each needs a proper curb and a flashing worked into the membrane. Sealant around a pipe is not a flashing, and it is what we find most often.

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.

  • Who can give access to the top floor and the roof
  • The parapet coping and upstand before the membrane field
  • Whether the outlet is clear, because everything drains internally
  • How far the water has traveled inside before it showed

Chimney flashing repair cost in Midtown

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. Expect access to appear as a line. A roof reached through an occupied unit, or a frontage on a busy street, is time before any work starts -- and on a parapet roof the outlet and coping are part of the job whether or not they are what you called about.

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.

Buildings in Midtown

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

Parapets are the Midtown story. A building with a flat roof behind a street-facing parapet fails at the coping and the upstand, not in the field, and the water appears inside on the top floor a long way from where it entered. Access is the other constraint: a roof reached only through an occupied unit changes how the work has to be arranged.

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.

My roof has been repaired twice and still leaks. Why?

Almost certainly because the repair went where the ceiling was wet rather than where the water entered. Water gets in at a junction, runs along a rafter and drops at the first low point, which on a shallow pitch can be several feet away. That is why the roof space gets inspected here before anything is quoted -- the underside of the deck shows the direction of travel.

The ceiling stains when it has not rained. Is that the roof?

That is an ice dam, and it is the opposite of a rain leak. Heat escaping into the roof space melts snow on the upper roof; the meltwater refreezes at the cold eaves and dams; water then backs up behind it and goes in above the line the covering sheds from. It shows up during a thaw. The lasting fix is insulation and ventilation, not shingles.

What is the 25% rule for roofing?

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.
