Chimney Flashing Repair in Roselle Park from $300. $300 to $1,200 around a chimney, vent or skylight -- and the commonest leak on this housing stock. Free inspection and a written quote.
A chimney on a steep roof collects more water against its upslope face than one on a shallow roof, which is why the back gutter behind the stack is the detail that fails here. It is also the one most often missing entirely on older work.
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.



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. Steeper pitch means staging rather than walking the roof, and that is genuine labor rather than padding. Against that, steep roofs shed well, so the repair itself is more often a single specific detail than a general problem -- which keeps the scope small.
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.
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.
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.
Steeper pitch changes the repair rather than the price. A steep roof sheds well, so leaks here are less often about standing water and more often about a specific failed detail -- a valley, a chimney, a vent. It also means staging rather than simply walking the roof, and that does belong in the quote.
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.
Steep pitches shed water well, which means a Roselle Park leak is usually a specific failed detail rather than a general problem -- a valley, a chimney, a vent boot.
Deeper eaves make ice dams worse, not better.
On a steep roof the valley is the usual culprit.
There is less low slope here than anywhere else covered on this site, so when it appears it is a small porch or bay roof -- and a small roof has the worst ratio of edge detail to field.
Steeper pitch means shingle lasts longer here than on the shallower post-war roofs, because water spends less time on it.
A steep roof is not a roof to put a temporary cover on in the dark in the wet.
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.
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.
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.
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.
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.
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.
No. The inspection is free, it covers the roof space as well as the roof, the written quote is free, and neither carries an obligation. The written cause is yours to keep even if you use somebody else. What we will not do is give you a price at the curb without going up.
The roof space walked as well as the roof, before any price. The cause named in writing, not just the work.
