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 Glen Ridge?
Newark Quality Roofing rebuilds the metal that seals the chimney on Glen Ridge's pre-WWII Victorian, Edwardian, Colonial Revival, Tudor, and Dutch Colonial homes, where one, two, or three masonry chimneys each create the roof's largest penetration. Chimney flashing repair restores the apron, sidewall step, and upslope transitions that shed water around the chase.
The chimney is the most leak-prone detail on these steep, multi-gable rooflines, because the roofing industry estimates that roughly 90–95% of roof leaks originate at flashing and only 5–10% at the open shingle field, an industry estimate attributed to the NRCA. The corbelled brick and ornamental profiles on Glen Ridge's high-style houses demand flashing fit to each chimney rather than a continuous one-piece strip, which is a defective installation, per InterNACHI and shingle-manufacturer guidance.
The two-part system the NRCA specifies pairs base and step flashing woven one piece per shingle course with a separate counter flashing set into a reglet cut in a mortar joint, so a Newark Quality Roofing repair rebuilds both layers rather than smearing caulk over the symptom. Surface caulk or roofing cement alone cracks within a few years from masonry-versus-roof differential movement and freeze-thaw, per IIBEC.
Period detailing on Glen Ridge's slate, copper, and complex multi-gable roofs makes a chimney repair a preservation matter as well as a waterproofing one. A Newark Quality Roofing repair matches copper and non-ferrous flashing stock to the existing roof so the work blends into the surrounding slate or shingle field, the in-kind standard the Glen Ridge Historic Design Guidelines call for on regulated properties.
What Chimney Flashing Repair Problems Are Common in Glen Ridge?
Deteriorated mortar joints on Glen Ridge's century-old chimneys complicate counter flashing, because the cap locks into a reglet cut in clean, sound mortar, yet eroded or repointed joints break that mechanical hold. A Newark Quality Roofing repair restores the mortar joint before setting new counter flashing, rather than relying on adhesive that masonry-versus-roof movement cracks within a few years, per IIBEC.
Wide and multiple-flue chimneys on the larger high-style homes dam debris and meltwater on the upslope side without a cricket, the saddle IRC Section R1003.20 requires where a chimney measures wider than 30 inches parallel to the ridge. Many original Glen Ridge chimneys were built without one, so a Newark Quality Roofing repair builds or rebuilds the cricket as part of the lasting flashing repair.
Mature street-tree debris from the borough's heavy oak, maple, and elm canopy collects on the upslope face of a chimney and in the adjoining valleys, trapping moisture against the flashing and the masonry it anchors to. A Newark Quality Roofing repair clears the debris path and reseals the transitions where water concentrates on Glen Ridge's fully built-out, tree-lined lowland streets.

What Is Our Process for Chimney Flashing Repair in Glen Ridge?
Newark Quality Roofing diagnoses 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. The chimney is the roof's largest penetration, and the roofing industry estimates that roughly 90–95% of roof leaks originate at flashing, an industry estimate attributed to the NRCA, while 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 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 that locks the cap into the masonry. 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 and documents the completed repair, matching copper and non-ferrous flashing to the existing slate or shingle field, running a magnet sweep for nails at cleanup, and recording the work with photographs for the owner. On a regulated property in the Glen Ridge Historic District, a change in roofing material requires a Certificate of Appropriateness before the work, addressed below.
