Overview
Newark Quality Roofing delivers expert chimney flashing repair in Millburn — with prices starting from $400–$1,500 and free estimates available today. Chimney flashing repair on Millburn estates addresses the single most leak-prone junction on any residential roof -- the point where a masonry chimney penetrates the roof plane. The homes throughout Short Hills, Wyoming, and Glenwood feature substantial masonry chimneys, often multiple chimneys per residence, built from brick, stone, or stucco-over-block construction that creates large penetrations requiring step flashing, counter-flashing, cricket fabrication, and base flashing on all four sides. When any element of this multi-component system fails, water finds the path of least resistance into the building interior, typically emerging as ceiling stains, wall discoloration, or moisture damage to the framing around the chimney chase.
The chimney flashing on Millburn's older estates was originally installed using techniques and materials appropriate to their era -- hand-formed lead or copper step flashings set into mortar joints with lime-based pointing, fabricated crickets directing water around the uphill face. Decades of thermal cycling, mortar deterioration, and the freeze-thaw action that Millburn's climate imposes have fatigued these installations to varying degrees. Our chimney flashing repair practice evaluates the complete chimney-roof junction rather than addressing only the visible symptom, because partial repairs on chimney flashings are the most common source of recurring leak callbacks in residential roofing.
Properties in Montclair and Bloomfield share similar chimney-flashing challenges, but Millburn's typically larger chimneys -- some incorporating multiple flues, decorative corbeling, and substantial mass -- create proportionally more complex flashing assemblies. A Short Hills estate chimney measuring four feet wide and three feet deep generates roughly twenty-eight linear feet of flashing perimeter, and the cricket required on the uphill face must divert water around a larger obstruction than standard chimney dimensions present.

Local Challenges in Millburn




Mortar-joint deterioration is the primary failure mechanism for chimney counter-flashings in Millburn. The counter-flashing -- the upper piece that is embedded in the mortar joint and overlaps the step flashing below -- relies on sound mortar to hold it in position and seal the joint against water intrusion. When the mortar deteriorates from decades of freeze-thaw cycling, the counter-flashing loosens, creating gaps that admit wind-driven rain directly into the step-flashing system. Repairing the flashing requires not just resetting the counter-flashing but repointing the surrounding mortar joints with material compatible with the original masonry -- a dual-trade skill combining sheet-metal and masonry expertise.
Cricket deterioration behind large chimneys creates ponding conditions that accelerate flashing failure. The cricket -- a small peaked structure on the uphill side of the chimney that diverts water around the obstruction -- is subject to the same material fatigue as the primary roof surface, but its position in a low-visibility area means deterioration often goes unnoticed until water is actively entering the building. On Millburn's larger chimneys, the cricket surface area is substantial enough to warrant the same material quality as the primary roof -- copper sheet on slate roofs, matching shingle material on asphalt roofs -- rather than the sheet-metal expedients that some contractors install.
Multi-chimney properties require coordinated assessment across all chimney-roof junctions. A Short Hills estate with three chimneys -- master fireplace, living room fireplace, and kitchen -- may show flashing deterioration at different stages on each, but the underlying causes are the same: age, thermal cycling, and mortar deterioration. Addressing only the chimney with the active leak while leaving the others to fail within the next few seasons results in repeated mobilization costs and disruption that a comprehensive assessment and phased repair plan would avoid.

Our Chimney Flashing Repair Process

Chimney flashing assessment begins with interior inspection of the spaces surrounding each chimney chase, looking for evidence of current or past water intrusion -- staining, mold, soft drywall, and moisture meter readings that indicate active moisture migration. This interior evidence, combined with exterior inspection of the flashing, mortar joints, chimney crown, and cricket condition, produces a diagnostic picture that identifies all contributing failure points rather than just the most visible one.

Repair fabrication occurs in our sheet metal shop based on field measurements taken during assessment. Step flashings are cut and bent to match the coursing pattern of the roof material -- slate, shingle, or shake -- with dimensions specific to each chimney face. Counter-flashings are formed to the profile required for embedding in the specific masonry joint identified during assessment. Crickets are fabricated from copper or coated steel depending on the primary roof material. All components are finished before the installation crew arrives on site, eliminating field fabrication that introduces quality variability.

Installation follows a sequence dictated by the overlapping relationship between components. The existing flashing is carefully removed -- preserving adjacent roofing material wherever possible. Base flashing is installed first, lapping onto the roof deck and up the chimney face. Step flashings are woven into the roof coursing on the sides. The cricket is installed on the uphill face and integrated with the step flashings at each side. Counter-flashings are set into prepared mortar joints and sealed. The completed assembly is water-tested before the crew demobilizes, verifying that no path remains for water to bypass the new flashing system.
