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 Cedar Grove?
Newark Quality Roofing repairs chimney flashing on Cedar Grove's postwar ranches, split-levels, and colonials and on Pompton Avenue / Route 23 storefronts, rebuilding the metal sealing the chimney, the roof's largest penetration, at the apron, sidewall, and upslope transitions.
Chimney flashing repair starts at the transition metal, because the roofing industry estimates that roughly 90–95% of roof leaks originate at flashing details and only 5–10% at the open shingle field, an industry estimate attributed to the NRCA. The NRCA specifies a two-part chimney flashing system, so a repair restores both layers rather than smearing sealant over the symptom.
The apron, sidewall step, and upslope transitions all carry water past the chimney, and a single failed counter flashing or cracked caulk joint admits water into the chase on Cedar Grove's tree-shaded single-family stock. A repair rebuilds the failed transition rather than chasing the visible drip.
The Pompton Avenue / Route 23 storefronts and the older period homes on Cedar Grove's higher ground carry masonry chimneys whose galvanized step and counter flashing corrode at the mortar joint, and a repair sets a new cap into a clean reglet cut in the masonry.
What Chimney Flashing Repair Problems Are Common in Cedar Grove?
Surface caulk smeared over no underlying metal is the most common failed repair on Cedar Grove chimneys, because masonry-versus-roof differential movement and freeze-thaw crack the sealant within a few years, per IIBEC. A lasting repair rebuilds the metal beneath rather than recaulking the joint.
Counter flashing pulled loose from the mortar joint breaks the mechanical lock the NRCA two-part system sets into a reglet, so meltwater and rain run behind the cap into the chase. A repair cuts a clean reglet into a horizontal mortar joint and locks a new cap into the masonry rather than relying on adhesive.
A missing cricket on a chimney wider than 30 inches dams ice, snow, and reservation-edge canopy debris against the upslope face on Cedar Grove's tree-shaded slopes, accelerating flashing deterioration. The cricket, a saddle IRC Section R1003.20 requires on a wide chimney, diverts water and debris around the masonry.
Deteriorated step flashing woven into the shingle courses on older Cedar Grove chimneys corrodes and lifts, exposing the sidewall to wind-driven rain, and a continuous one-piece strip at a chimney marks a defective installation, per InterNACHI and shingle-manufacturer guidance. A repair reweaves the metal one piece per shingle course.

What Is Our Process for Chimney Flashing Repair in Cedar Grove?
Newark Quality Roofing diagnoses the chimney flashing at all four transitions — the downslope apron, the two sidewall step runs, and the upslope head or cricket — tracing the entry point before resealing. A diagnosis starts at the chimney because it is the roof's largest penetration, and a continuous one-piece strip at the sidewall flags a defective original installation, per InterNACHI and shingle-manufacturer guidance.
Newark Quality Roofing rebuilds the NRCA two-part flashing system: step and base flashing woven one piece per shingle course, plus a separate counter flashing set into a reglet cut in a mortar joint. The counter flashing locks into the masonry mechanically rather than relying on adhesive that masonry-versus-roof differential movement and freeze-thaw crack within a few years, per IIBEC, and a crew installs a self-adhering ice-and-water membrane that self-seals around fasteners at the chimney base, per ASTM D1970. Where a chimney measures wider than 30 inches parallel to the ridge, a crew builds a cricket to divert water and snow, per IRC Section R1003.20.
Newark Quality Roofing verifies watertight execution at every chimney transition, runs a magnet sweep for nails at cleanup, and documents the repair with photographs for your records and any insurance claim. A repair on a detached one- or two-family home counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, no inspection, and no notice, per the NJ Uniform Construction Code.
