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 Caldwell?
Newark Quality Roofing rebuilds chimney flashing on Caldwell's Victorian-era and Colonial Revival cores, interwar and postwar Capes and ranches, and the masonry chimneys that penetrate those older built-out roofs. Chimney flashing repair restores the metal that seals the chimney, the roof's largest penetration, where the apron, sidewall step, and upslope transitions each shed water.
Chimney flashing 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 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, so a Newark Quality Roofing repair restores both layers rather than smearing sealant over the symptom.
The masonry chimneys on Caldwell's older built-out blocks fail first at corroded or lifted step flashing, counter flashing pulled from the mortar joint, and surface caulk cracked by freeze-thaw. Mature street-tree debris collects against a chimney lacking a cricket, dams meltwater on the upslope face, and accelerates the deterioration that admits water into the chase.
What Chimney Flashing Repair Problems Are Common in Caldwell?
Mature street-tree debris against the upslope chimney face is the defining Caldwell chimney-flashing condition, because the borough's older built-out blocks sit under a heavy oak and maple canopy that drops leaf load against the masonry. The trapped debris dams meltwater, holds moisture against the flashing, and corrodes the metal that seals the chimney.
Deteriorated mortar joints on Caldwell's older masonry chimneys complicate a counter flashing reglet, because the cap locks into a reglet cut in a sound mortar joint, per the NRCA two-part standard, and a crumbling joint cannot hold the metal. A Newark Quality Roofing scope repoints the joint before setting the counter flashing rather than building a flashing system on a failing substrate.
Surface caulk and roofing cement smeared over the chimney base mark a temporary fix on many Caldwell roofs, because sealant alone over no underlying metal cracks within a few years from masonry-versus-roof differential movement and freeze-thaw, per IIBEC. A lasting repair rebuilds the woven step flashing and the reglet-set counter flashing the surface patch covered.
Wide multi-flue chimneys on Caldwell's larger Victorian-era homes amplify every flashing transition, because a chimney wider than 30 inches measured parallel to the ridge requires a cricket to divert water and snow, per IRC Section R1003.20. The wider the chimney, the longer the step runs and the more critical the upslope cricket becomes.

What Is Our Process for Chimney Flashing Repair in Caldwell?
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 diagnosis starts at the chimney because the chimney 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 movement and freeze-thaw crack within a few years, per IIBEC, and a self-adhering ice-and-water membrane 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 and documents the completed flashing, confirming watertight execution at every chimney transition, running a magnet sweep for nails at cleanup, and photographing each component. The documentation gives a Caldwell owner-occupant or a Bloomfield Avenue mixed-use owner a baseline record for future inspections and any insurance claim.
