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 North Caldwell?
Newark Quality Roofing repairs chimney flashing on North Caldwell's custom colonials, contemporaries, and Tudors on large wooded lots, rebuilding the metal that seals the chimney, the roof's largest penetration. Chimney flashing repair restores the apron, sidewall step, and upslope transitions where masonry meets the roof plane.
Chimney flashing is a two-part system, because the NRCA specifies base and step flashing woven one piece per shingle course plus a separate counter flashing set into a reglet cut in a mortar joint. A Newark Quality Roofing repair rebuilds both layers rather than smearing sealant over the symptom, and the chimney is where the roofing industry estimates roughly 90 to 95% of roof leaks originate at flashing details, an industry estimate attributed to the NRCA.
The borough's older custom stock carries the aging valley, chimney, and wall flashing that a North Caldwell repair addresses, on the natural-slate and copper period detailing of its Tudors and large estate homes. A Newark Quality Roofing crew matches new flashing stock to the existing color and product line, and sets a self-adhering ice-and-water membrane at the chimney base that self-seals around fasteners, per ASTM D1970.
What Chimney Flashing Repair Problems Are Common in North Caldwell?
Deteriorated mortar joints in North Caldwell's older custom and estate chimneys break the mechanical lock that holds counter flashing. Counter flashing depends on sound mortar to stay embedded in the chimney face, so when the joint crumbles, the cap separates and wind-driven rain runs behind the step flashing below.
The mature oak and maple canopy over North Caldwell's large wooded lots, dense near the Hilltop Reservation edge, drops leaf load, needles, and broken branches into the cricket behind a wide chimney. Trapped debris holds moisture against the cricket flashing and the masonry, accelerating deterioration and feeding leaks that surface inside the home away from the chimney itself.
Wide estate chimneys on North Caldwell's custom colonials and Tudors often measure more than 30 inches parallel to the ridge, where a cricket is required to divert water, ice, and snow around the upslope face, per IRC Section R1003.20. A chimney built without that saddle dams meltwater and debris against its uphill side, so a Newark Quality Roofing repair adds the cricket the code calls for.

What Is Our Process for Chimney Flashing Repair in North Caldwell?
Newark Quality Roofing inspects all four chimney transitions and traces the entry point before resealing. A crew checks the downslope apron, the two sidewall step runs, and the upslope head or cricket, starting at the chimney because it is the roof's largest and most leak-prone 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 system, weaving new step and base flashing one piece per shingle course and setting a counter flashing into a clean reglet cut in a mortar joint that locks the cap into the masonry. A crew repoints the joints at and above the roofline, applies a self-adhering ice-and-water membrane at the chimney base, per ASTM D1970, and builds a cricket where the chimney exceeds 30 inches parallel to the ridge, per IRC Section R1003.20.
The completed repair is verified watertight at every chimney-to-roof junction, with the work documented in timestamped photographs keyed to each chimney. A Newark Quality Roofing lead runs a magnet sweep for nails at cleanup and leaves a written workmanship warranty on the labor, separate from the manufacturer material warranty, along with a maintenance note on clearing cricket debris.
