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 Maplewood?
Newark Quality Roofing repairs chimney flashing on Maplewood's architect-designed early-20th-century Tudor, Colonial Revival, and Italian Revival homes and the masonry chimneys above Maplewood Village and Springfield Avenue storefronts. 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.

Chimney flashing fails first on Maplewood's older architect-designed stock, where galvanized step flashing corrodes, counter flashing pulls from the mortar joint, and surface caulk cracks under masonry-versus-roof movement and freeze-thaw, per IIBEC. A Newark Quality Roofing repair 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 two-part transitions all shed water on a Maplewood chimney: the downslope apron, the two sidewall step runs woven one piece per shingle course, and the upslope head or cricket. The NRCA specifies a two-part chimney flashing system — base and step flashing 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.
Reservation-edge canopy loads the chimney transitions on western Maplewood homes, because the South Mountain Reservation reaches into the wooded Wyoming section and drops leaf and branch debris that dams against the upslope chimney face and holds moisture in the valleys, accelerating corrosion of the flashing metal. A Newark Quality Roofing repair clears the upslope debris and rebuilds the failed transition before resealing.
What Chimney Flashing Repair Problems Are Common in Maplewood?




Deteriorated mortar joints complicate counter flashing on Maplewood's older architect-designed chimneys, because a reglet cut into a sound mortar joint locks the cap into the masonry, per the NRCA two-part standard, while crumbling mortar gives the metal no anchor. A Newark Quality Roofing repair cuts the reglet into a sound joint and avoids the adhesive that masonry-versus-roof movement and freeze-thaw crack within a few years, per IIBEC.
Wide chimney faces on Maplewood's larger period homes dam debris, ice, and meltwater on the upslope side, because a chimney measuring wider than 30 inches parallel to the ridge requires a cricket to divert water around the mass, per IRC Section R1003.20. A Newark Quality Roofing repair builds the cricket where the width crosses that threshold so the upslope face sheds water instead of trapping it.
Reservation-edge tree canopy intensifies chimney flashing failure on Maplewood's western Wyoming slopes, where the South Mountain Reservation drops leaves and branches that collect on the upslope chimney face and hold moisture against the metal and mortar. A Newark Quality Roofing repair clears the debris dam and addresses the corroded step flashing before installing the rebuilt two-part system.

What Is Our Process for Chimney Flashing Repair in Maplewood?

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 the chimney is the roof's largest penetration, and the roofing industry estimates that roughly 90–95% of roof leaks originate at flashing details, an industry estimate attributed to the NRCA. 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 on the Maplewood chimney: 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 installs a self-adhering ice-and-water membrane that self-seals around fasteners at the chimney base, per ASTM D1970. Where the chimney measures wider than 30 inches parallel to the ridge, a crew builds a cricket, 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 finished flashing with photographs for the owner record. A repair of the roof covering on a detached one- or two-family Maplewood home counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, no inspection, and no notice, per the NJ Uniform Construction Code, while a Village or Springfield Avenue commercial building exceeding 25% of the roof area in a 12-month period files with the Township of Maplewood Construction Division.
