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 Livingston?
Newark Quality Roofing repairs chimney flashing on Livingston's post-war split-levels, raised ranches, and center-hall colonials, rebuilding the metal that seals the chimney where the apron, the sidewall step runs, and the upslope head or cricket each shed water. Chimney flashing repair restores the chimney, the roof's largest penetration.

Chimney flashing repair starts at the transition metal, because the roofing industry estimates that roughly 90 to 95% of roof leaks originate at flashing details and only 5 to 10% at the open shingle field, an industry estimate attributed to the NRCA. The NRCA specifies a two-part system: base and step flashing woven one piece per shingle course, plus a separate counter flashing set into a reglet cut in a mortar joint.
The masonry chimney on Livingston's mid-century blocks compounds the failure, because mortar joints open over decades of freeze-thaw cycling where the counter flashing was originally embedded, and a continuous one-piece strip at the sidewall flags a defective original installation, per InterNACHI and shingle-manufacturer guidance. A Newark Quality Roofing repair rebuilds both layers rather than smearing sealant over the symptom.
Counter flashing locks into the masonry mechanically rather than relying on adhesive, because caulk or roofing cement alone over no underlying metal cracks within a few years from masonry-versus-roof differential movement and freeze-thaw, per IIBEC. A Newark Quality Roofing crew sets a new cap into a clean reglet and integrates an ice-and-water membrane that self-seals around fasteners at the chimney base, per ASTM D1970.
What Chimney Flashing Repair Problems Are Common in Livingston?




A missing cricket behind a chimney is frequent on Livingston's older split-levels and colonials, where the upslope face dams mature-canopy leaf debris, holds standing water, and concentrates ice against the masonry. A cricket is required on the upslope side of a chimney wider than 30 inches parallel to the ridge, per IRC Section R1003.20.
Counter-flashing reglet cutting in aging Livingston chimney masonry requires diamond-blade equipment and careful technique to channel the cap into a horizontal mortar joint without cracking the brick, and deteriorated joints add tuck-pointing before the new cap seats, the masonry restoration that accompanies a lasting flashing repair on the township's mid-century stock.
Addition-transition flashing failures cluster where 1990s-to-2000s additions meet the original framing on Livingston colonials and split-levels, so a chimney that sits at a reworked roof plane needs its apron, sidewall step runs, and upslope head integrated with the addition valley rather than patched in isolation.

What Is Our Process for Chimney Flashing Repair in Livingston?

Newark Quality Roofing inspects all four chimney transitions — the downslope apron, the two sidewall step runs, and the upslope head or cricket — and traces the entry point before resealing. A crew starts at the chimney because it is the roof's largest penetration, and a continuous one-piece strip at the sidewall flags a defective 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, with deteriorated joints tuck-pointed first. A crew applies a self-adhering ice-and-water membrane at the chimney base that self-seals around fasteners, per ASTM D1970, and builds a cricket where the chimney exceeds 30 inches parallel to the ridge, 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 rebuilt apron, step, counter flashing, and cricket with photographs for the homeowner's record and any insurance claim.
