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 South Orange?
Newark Quality Roofing repairs chimney flashing on South Orange's large pre-war Victorians, Colonial Revivals, and Tudor Revivals, plus the Colonials and Capes on the Village's tree-lined streets. Chimney flashing repair rebuilds the metal that seals the chimney, the roof's largest penetration, where the apron, sidewall step, and upslope transitions each shed water.
Pre-war chimneys carry the heaviest leak load on South Orange's mature stock, because over half the Village housing predates 1940 and 82% predates 1960, per the Township planning evaluation, and decades of thermal cycling and mortar deterioration pull the original flashing from the masonry. A Newark Quality Roofing repair starts at the failed transition rather than the visible drip.
The two-part system is what a lasting chimney repair restores, 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 continuous one-piece strip at the chimney is a defective installation, per InterNACHI and shingle-manufacturer guidance.
The Montrose Park district sets a separate approval step on a designated property, because exterior roofing work there requires a Certificate of Appropriateness under Village Code Chapter 185 before a construction permit. A Newark Quality Roofing scope on a Montrose Park home matches the new flashing to the period detailing so the chimney transition stays watertight.
What Chimney Flashing Repair Problems Are Common in South Orange?
Mortar deterioration drives most chimney flashing failure on South Orange's aging pre-war homes, because as the mortar joint ages it cracks and releases the counter flashing from its reglet, allowing water behind the step flashing below. Surface caulk alone over no underlying metal cracks within a few years from masonry-versus-roof movement and freeze-thaw, per IIBEC.
Period detailing on the large Victorians, Colonial Revivals, and Tudor Revivals of Montrose Park and the Wyoming sections shapes the flashing scope, because slate, metal, and copper roofs and decorative masonry demand counter flashing set cleanly into the mortar joint rather than a surface patch. A Newark Quality Roofing crew matches the new flashing stock to the existing roof color and product line.
Wide chimneys on the larger period homes require a cricket on the upslope side where the chimney measures wider than 30 inches parallel to the ridge, per IRC Section R1003.20, to divert water, ice, and snow around the masonry. The heavy South Mountain canopy that South Orange streets carry, over 8,000 shade trees across 181 Village streets per the Township Fast Facts, loads the upslope face with debris that dams meltwater without the cricket.

What Is Our Process for Chimney Flashing Repair in South Orange?
Newark Quality Roofing inspects all 4 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 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: 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 crew sets a self-adhering ice-and-water membrane at the chimney base that self-seals around fasteners, per ASTM D1970. Where a chimney exceeds 30 inches parallel to the ridge, a crew builds a cricket, per IRC Section R1003.20.
Newark Quality Roofing fills the reglet, resets the surrounding slate, shingle, or metal against the new flashing, and documents the completed transition with photographs. A lead verifies watertight execution at every chimney transition and runs a magnet sweep for nails before leaving the property, and the photo record supports a South Orange homeowner's maintenance file or any insurance claim.
