Overview
Newark Quality Roofing delivers expert chimney flashing repair in Newark — with prices starting from $400–$1,500 and free estimates available today. Newark's skyline from Branch Brook Park reveals thousands of brick chimneys rising from brownstone rooftops across the North Ward, Forest Hill, and Roseville -- silent witnesses to a century of coal heat, oil conversion, gas retrofits, and now, in many cases, decorative obsolescence. Whether your chimney still vents a furnace, serves a working fireplace, or stands as an architectural relic on a building that switched to forced air decades ago, the flashing where masonry meets roofing material is the single most leak-prone junction on any Newark roof.
Chimney flashing failure accounts for roughly a third of all residential roof leak calls we receive from Newark homeowners. The reason is mechanical: a chimney is a rigid masonry column penetrating a flexible roof plane, and every temperature cycle, wind gust, and settling event drives micro-movement between the two. In Newark's dense urban environment, this natural stress is compounded by the urban heat island effect -- chimney bricks absorb and radiate heat at rates that accelerate mortar deterioration and sealant breakdown faster than identical installations in surrounding suburbs.
The wide chimneys on Newark's pre-war brownstones -- often thirty inches or more across the slope -- create a particular hydraulic challenge that smaller suburban chimneys don't face. Water running down the roof plane hits the upslope face of a wide chimney and pools behind it, creating hydrostatic pressure that forces water under base flashing and into the building. The solution is a cricket, also called a saddle: a peaked diverter built behind the chimney to shed water around rather than against it. Many of Newark's original chimney installations never included crickets, and retrofitting them is one of our most impactful chimney flashing repairs.
Our chimney flashing work in Newark integrates roofing expertise with masonry knowledge, because the two disciplines are inseparable at the chimney junction. We repoint deteriorated mortar joints in the courses immediately adjacent to flashing embedments, rebuild crumbling chimney crowns that allow water to enter from above and bypass flashing entirely, and install stainless steel chimney caps that prevent rain entry into the flue. This holistic approach eliminates the common Newark scenario where a homeowner pays for flashing repair only to discover that water was also entering through the chimney crown or deteriorated mortar above the flashing line.
Local Challenges in Newark
Cricket installation behind wide brownstone chimneys is the most significant chimney flashing challenge unique to Newark's housing stock. A thirty-inch-wide chimney without a cricket creates a dam that traps water, ice, and debris on the upslope side. During Newark's freeze-thaw season from November through March, ice accumulates behind these wide chimneys and exerts lateral force on base flashing, eventually breaking the seal. Retrofitting a cricket onto an existing roof requires cutting back shingles, building a framed saddle structure, waterproofing with membrane, and re-shingling -- a substantial but essential repair that prevents the annual cycle of winter leaks that plague many North Ward brownstones.
Mortar reglet integrity on century-old chimneys presents a constant challenge. The lime mortar used in Newark's pre-war chimneys has softened over decades of exposure, and counter-flashing embedded in these deteriorated joints loses its purchase. Standard practice of simply re-caulking the reglet provides temporary relief at best. Proper repair requires raking out deteriorated mortar to a depth of three-quarters of an inch, installing new counter-flashing with stainless steel wedges, and repointing with mortar that matches the original lime composition -- not modern Portland cement, which creates a hard edge that cracks the surrounding soft brick.
Multi-flue chimneys on Newark's larger brownstones and converted multi-family buildings add complexity that single-flue residential chimneys don't present. A chimney serving three or four units may have separate flue liners, each with its own cap and crown condition, while sharing a single flashing perimeter. Deterioration in one flue's crown can send water behind flashing that serves all units, creating leaks in apartments far from the actual point of failure. Diagnosing which pathway is responsible requires systematic water testing of each flue and crown section independently.

Our Chimney Flashing Repair Process
Chimney flashing repair in Newark begins with a comprehensive chimney condition assessment, not just a flashing inspection. We examine the chimney from cap to base: crown condition, mortar joint integrity in the top eight courses, flue liner visibility, counter-flashing embedment depth, step flashing condition along each side, base flashing at the front and rear faces, and cricket presence or absence behind wide chimneys. This full assessment prevents the costly scenario where a homeowner pays for flashing repair while the actual water entry point is a cracked crown or deteriorated mortar six courses above the flashing line.
Flashing removal and surface preparation follow the assessment. We strip existing counter-flashing and step flashing completely rather than layering new material over old -- a shortcut that traps moisture and accelerates corrosion. Masonry surfaces are cleaned of old sealant, loose mortar is raked to sound depth, and any damaged brick faces are addressed before new flashing installation begins. On the roof side, we remove shingles back far enough to install ice-and-water shield membrane as secondary protection beneath the new step flashing courses.
Installation proceeds in sequence: base flashing at the front face, step flashing up each side in alternating courses with shingles, rear base flashing integrated with the cricket if one exists or is being added, and finally counter-flashing embedded in freshly raked and repointed reglet joints. Every piece overlaps the one below it by a minimum of four inches, and every reglet joint receives flexible polyurethane sealant compatible with the existing mortar chemistry. The finished system creates a continuous water barrier with no path for wind-driven rain to penetrate.
Post-installation testing and documentation close every chimney flashing project. We run controlled water from a garden hose across each face of the chimney in sequence, starting at the top and working down, to verify no penetration at any flashing course. Interior inspection confirms dry conditions at the ceiling below. The homeowner receives annotated before-and-after photographs, a diagram of the installed flashing system, and a maintenance schedule that flags the specific inspection points most vulnerable to Newark's thermal cycling and freeze-thaw conditions.
