New copper counter-flashing and step flashing sealed at the chimney base on a Paterson roof

Chimney flashing is the layered metal system that keeps water out of the seam where masonry meets the roof plane. On Paterson rowhomes, that seam opens as mortar cracks and old roof cement dries out and flakes away.

We start with a roof condition survey, then remove the failed flashing and any rotted decking beneath it. New step flashing, counter-flashing, and an apron flashing are set over a self-adhered ice-and-water shield, fastened with ring-shank nails, and hand-sealed at every lap.

A typical chimney reseal runs a few hundred dollars when the masonry is sound. Full flashing rebuilds with new underlayment, drip edge, and sheathing repairs cost more, and we quote each line item before any tear-off starts.

On flat porch roofs and low-slope sections near the chimney, we also apply reflective silicone coatings or acrylic elastomerics. Primer systems from Henry, GAF Unisil, or Tropical Roofing extend membrane life and cut summer heat gain on the rooftop.

What's Included

A full roof condition survey of the chimney base, counter-flashing, and surrounding field course before we quote.
Careful removal of the old flashing, tar, and roof cement without breaking the shingles, slate, or clay tile around it.
New copper or aluminum counter-flashing cut and bent to fit the actual chimney footprint, not a stock size.
Step flashing woven into each staggered course along the chimney sidewall so the laps shed water downhill.
An apron flashing at the low side plus a cricket where the roof pitch meets the brick, which is where water stalls.
Replacement of any rotted sheathing, plywood, or OSB we find once the old metal is off the substrate.
Self-adhered ice-and-water shield run along the chimney and the eave before the flashing is fastened down.
A bead of polyurethane sealant at the masonry joint, plus a hose test on the chimney before we pack up.

Our Chimney Flashing Process

What Our Chimney Flashing Process Includes

We photograph the chimney from the ladder and check the counter-flashing, step flashing, and masonry joint before quoting.
We look at the surrounding field course for granule loss, curling, and blistered shingles that would shorten the repair's life.
We set a tarp over the chimney opening when rain is forecast, so the interior stays dry while we work.
We cut out the old metal, tar, and failed caulk with a pry bar and roofing shovel, then bag every bit of debris.
We replace rotted plywood or OSB sheathing and inspect the rafters and truss ends before covering them again.
We install new copper or aluminum flashing over ice-and-water shield, using ring-shank nails at each lap and stagger.
We seal the masonry joint with polyurethane caulk or roof cement and hose-test the assembly before we leave.
We haul away the old shingle and metal in a dumpster, then walk the finished lap with you if you want to see it.

Signs You Need Chimney Flashing

Signs Your Chimney Flashing Needs Attention

Brown or rust-colored stains on the chimney breast or the ceiling below, which usually show up a day after a heavy nor'easter.
Rust streaks running down the brick or along the roofline, a sign that counter-flashing has corroded through.
Cracked or missing sealant at the masonry joint, where freeze-thaw cycles open the gap a little wider every winter.
Lifted, curled, or missing step flashing along the chimney sidewall after a windstorm peels it back.
Granule loss and bald spots on the shingles nearest the chimney, where runoff erodes the asphalt surface.
Damp, spongy roof deck or stained decking near the chimney, which means water has wicked past the underlayment.
Ice damming above the chimney, forming when attic heat melts snow that refreezes at the eave and gutter.
Algae-stained or mossy brick on the shaded side, which holds moisture and keeps the flashing wet.

Chimney Flashing — Frequently Asked Questions

What does chimney flashing cost in Paterson?

Chimney flashing costs a few hundred dollars when the masonry is sound and we only reset the metal and sealant. A full rebuild with new underlayment, decking repair, and custom counter-flashing runs higher, and we itemize the estimate before any tear-off begins.

How long does a chimney flashing repair take?

Chimney flashing repair is normally a one-day job on a standard pitched roof. If we find rot in the sheathing or have to replace plywood and a rafter, the work can stretch into a second day.

Will insurance cover chimney flashing damage?

Chimney flashing damage from wind, hail, or a falling limb is often covered, and we help with insurance claim assistance. We photograph the damage, note the storm date, and hand you a line-item scope an adjuster can read.

Can you fix chimney flashing without replacing the roof?

Chimney flashing can usually be repaired on its own if the surrounding field course still has life left in it. When the shingles are curled, buckled, or at end-of-life wear, we say plainly that a repair will not hold.

Do you repair chimney flashing on flat and commercial roofs?

Chimney flashing on flat roofs uses different materials, including TPO, EPDM, and PVC membrane systems, modified bitumen, and built-up roof assemblies. Those buildings also have parapet walls, scupper drains, and coping metal, so we survey the whole roof first.

When is the best time to service chimney flashing in Paterson?

Chimney flashing can be serviced in almost any month, but late spring and early fall give the sealant the best curing weather. We handle emergency roof repair and tarp a chimney any time water is coming inside.

Don't just take our word for it — hear from our satisfied customers.

"We had a brown stain spreading on the ceiling below our chimney for two winters. The crew pulled the old tar, found rotted sheathing, and rebuilt the step flashing and counter-flashing in a day. No leak since." — Maria G., Eastside

"Rain ran down the brick during every thunderstorm and pooled on our porch roof. They replaced the apron flashing and resealed the joint with polyurethane caulk. Fair price and a clear explanation of what failed." — David R., Hillcrest

"Our 1920s rowhome near South Paterson had a chimney leak two other roofers missed. They ran a roof condition survey first and showed us photos of the corroded counter-flashing before quoting a number." — Ana P., South Paterson
