What Is Chimney Flashing Repair?
Chimney flashing is the two-part sheet-metal system that seals the chimney to the roof, pairing base and step flashing woven into the shingle courses with a separate counter flashing set into the masonry. Chimney flashing waterproofs the chimney, the roof's largest penetration.
What Chimney Flashing Repair Is Available in Orange?
Chimney flashing repair on Orange's masonry chimneys restores the base, step, and counter flashing where aged brick, softened lime mortar, and the roof line meet across the city's older pre-1939 two- and three-family housing.

Orange's building stock frames the local problem: a township roughly 76% renter-occupied, with owner-occupancy near 23.8% per U.S. Census QuickFacts, dense with investor-owned two- and three-family buildings where one chimney often serves several units behind a single flashing perimeter. On masonry that is roughly half pre-1939, the brick chimney is the roof's largest penetration, so a failed counter flashing surfaces as the top-floor and shared-wall stains common across Orange's rental rows.
The step-and-counter rebuild answers that condition with the layered system the NRCA specifies: base and step flashing woven one piece per shingle course, then a separate counter flashing set into a reglet cut in a mortar joint. On the older detached homes of the Seven Oaks section and Orange's pre-1939 frame stock, a Newark Quality Roofing repair restores both layers into sound masonry rather than smearing sealant over the symptom — the reason flashing details, not the open shingle field, account for roughly 90–95% of roof leaks by an industry estimate attributed to the NRCA.
Counter flashing into aged mortar is what makes an Orange repair last: the metal locks mechanically into a reglet cut in the joint instead of relying on adhesive, because masonry-versus-roof differential movement and freeze-thaw crack surface caulk within a few years, per IIBEC. Where a wide chimney exceeds 30 inches measured parallel to the ridge, a cricket diverts water and snow around the upslope face, the saddle required under IRC Section R1003.20 — a frequent gap on Orange's older detached houses.
What Chimney Flashing Repair Problems Are Common in Orange?




Counter flashing on century-old chimneys loses its grip across Orange's roughly half pre-1939 housing, where the lime mortar joints have softened and surface re-caulking the reglet holds only briefly.
Softened mortar joints mean caulk or roofing cement alone over no underlying metal cracks within a few years from masonry-versus-roof movement and freeze-thaw, per IIBEC. A durable Orange repair rakes the joint, sets new counter flashing into the cut reglet, and locks the metal into the masonry per the NRCA two-part standard, restoring purchase the aged brick can no longer give to adhesive alone.
Tenant-occupied access shapes nearly every Orange chimney job, because the city's heavily renter-occupied two- and three-family buildings put a leak in one apartment while the failed transition sits over another behind the shared flashing perimeter. A Newark Quality Roofing job coordinates entry under New Jersey landlord–tenant notice, isolates the failed transition, and documents the work for the owner and any insurer.
Wide masonry chimneys on Orange's older detached homes often exceed 30 inches parallel to the ridge — the width at which IRC Section R1003.20 requires a cricket — yet many predate that provision and have none, so the upslope face dams meltwater, ice, and debris against the brick. Orange sits at the eastern foot of the first Watchung ridge, and the dense street-tree canopy plus the wooded slope to the west drop leaves and branches that collect behind a crowded chimney. Retrofitting the saddle cuts back shingles, frames and waterproofs the diverter, and re-shingles the field.

What Is Our Process for Chimney Flashing Repair in Orange?

Chimney flashing repair in Orange opens by diagnosing all four transitions on the masonry — the downslope apron, the two sidewall step runs, and the upslope head or cricket — tracing the entry point before any reseal.

The four-transition diagnosis matters most on Orange's aged brick, where it separates a spot reseal from a full rebuild and flags defective original work: a continuous one-piece metal strip at the sidewall marks a faulty installation, because step flashing seals only when woven one piece per shingle course, per InterNACHI and shingle-manufacturer guidance. On tenant-occupied stock the diagnosis isolates the failed transition before access is scheduled, and a written estimate documents it with photographs and sets scope, labor, materials, and timeline.

The two-part rebuild into the mortar strips corroded step flashing and loose counter flashing rather than layering new metal over old, weaves fresh step flashing one piece per shingle course, and sets the counter flashing into a reglet raked into the joint, the system the NRCA specifies. A self-adhering ice-and-water membrane that self-seals around fasteners protects the chimney base, per ASTM D1970, and a cricket is built where the chimney exceeds 30 inches parallel to the ridge, per IRC Section R1003.20.

Counter flashing, cleanup, and the local approval check close the project: every course locks into freshly raked reglet joints, the crew verifies a watertight result at each chimney face, runs a magnet sweep for nails, and photographs the finished system for the owner. A roof-covering repair on a detached one- or two-family Orange home is ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, per the NJ Uniform Construction Code; inside Orange's four designated historic districts, regulated exterior work requires a Certificate of Appropriateness first.
