About this service
Chimney Flashing Repair in Galloway, New Jersey
Chimney flashing repair in Galloway, New Jersey means replacing or resealing the metal that bridges your roof and your chimney. Flashing is the stepped, layered metal that sheds water away from the chimney chase. When it rusts through, lifts at the shingle line, or gets smeared with tar by a previous roofer, water runs straight down the masonry. We remove the failed metal, cut a clean reglet into the brick, and install new copper or stainless steel with proper counter-flashing.
Galloway homes take a beating from nor'easters, salt air near the coast, and freeze-thaw cycles that open seams every winter. Most of the flashing failures we see in Galloway Township and Smithville start as a small rust stain on the ceiling, then turn into soaked insulation and spalling brick within a season. If you have been searching for chimney flashing repair near me in Galloway, we handle the diagnosis, the metal work, and the roof tie-in in one visit.

What's included
What Our Flashing Repair Includes
Every flashing job includes the diagnosis, the metal work, and the water test. We list what is covered up front so you know exactly what you are paying for. Add-ons like crown repair or tuckpointing are quoted separately if we find them.
✓
Roof and Attic Leak Diagnosis
We inspect the roof, the flashing detail, and the attic with an inspection camera. You get photos of the failure point and a written explanation of what is leaking and why. This step alone saves customers from paying for the wrong repair.
✓
New Step and Counter-Flashing
We install new copper or stainless steel step flashing and counter-flashing cut into a fresh reglet. Fasteners are stainless, and we use ChimneySaver or HomeSaver sealant rated for masonry. This is the core of the repair and the part that stops the leak.
✓
Reglet Cut and Seal
A masonry chisel and angle grinder cut a clean 1-inch reglet into the brick. We pack it with refractory mortar and seat the counter-flashing into it. A proper reglet is what separates a real repair from a tar patch that fails in a year.
✓
Shingle Reset and Roof Tie-In
We lift and reset the shingles around the chimney, replace any torn underlayment, and tie the new flashing into the roof course correctly. No exposed nails, no smeared roof cement, no shortcut that shows up as a leak next spring.
✓
Water Test and Photo Report
We run a 15 to 20 minute hose test on the roof and check the attic for moisture. If it is dry, we photograph the finished work and email you the report. You get a 5-year workmanship warranty on the flashing.
How it works
How Our Flashing Repair Process Works
01
Roof and Attic Inspection
We start on the roof and finish in the attic. An inspection camera shows us exactly where water is entering, and we check the flashing, counter-flashing, step flashing, and the roof-to-chimney transition. This takes about 45 minutes on a typical Galloway ranch or two-story colonial.
02
Written Scope and Price
You get a written scope before we touch anything. It lists the metal type, the reglet depth, whether we need to reset shingles, and the total price. No surprise add-ons after the fact. Most flashing repairs land between $350 and $950 depending on chimney size and roof pitch.
03
Remove Failed Metal
We pull the old flashing, tar, and any roofer's patch. A masonry chisel and angle grinder cut a clean reglet into the brick so the new counter-flashing seats properly. We inspect the roof deck and replace any soft sheathing while it is open.
04
Install New Flashing
New copper or stainless steel step flashing goes in first, then counter-flashing set into the reglet with masonry-grade sealant. We use ChimneySaver and HomeSaver components on most jobs. Everything gets fastened with stainless screws, not nails, so it holds through coastal wind.
05
Water Test and Cleanup
We run a hose test on the roof for 15 to 20 minutes and check the attic for any sign of moisture. If it is dry, we seal the reglet, reset shingles, and clean the gutters of debris. You get before-and-after photos and a 5-year workmanship warranty on the flashing.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Inspection camera
We run a camera into the attic and flue to see exactly where water is entering. It turns a guessing game into a documented diagnosis.
Masonry chisel and angle grinder
Used to cut a clean 1-inch reglet into the brick so the new counter-flashing seats properly. A sloppy reglet is the number one cause of repeat leaks.
Tuckpointing trowel and mortar hawk
We repack the reglet and any deteriorated mortar joints with refractory mortar. These tools let us work fast without smearing mortar on the brick face.
Chimney brush and rods
On combined sweep-and-flashing calls we clean the flue first so we can inspect the liner for water damage. Creosote and water damage often show up together.
Power drill and stainless fasteners
We fasten flashing with stainless screws, never nails. Nails back out of coastal roofs, and that is how flashing lifts in the first place.
Damper clamp
Installed during inspections to keep the damper from fully closing on a gas log set. It is a small code item that comes up on almost every Galloway inspection.
Real results
Before and after.
Rusted Flashing on a Smithville Ranch
Before
A 1970s ranch in Smithville had a ceiling stain that returned every rain. The original steel step flashing was rusted through, and a previous roofer had smeared tar over the seam. The attic insulation was damp across a 4-foot section.
After
We removed the tar and rusted metal, cut a new reglet, and installed copper step and counter-flashing. A 20-minute hose test showed no moisture in the attic. The homeowner patched and painted the ceiling two weeks later.
Storm-Damaged Counter-Flashing in Pomona
Before
A nor'easter peeled the counter-flashing back on a Pomona colonial, and water was running down the chimney chase into the living room. The homeowner called on a Sunday with an active leak.
After
We tarped and sealed the chimney the same day. Two days later we installed new stainless counter-flashing and step flashing, reset the shingles, and ran a hose test. The leak stopped completely.
Inspection Fail in Galloway Township
Before
A Galloway Township home sale stalled when the inspector flagged rusted, lifted flashing. The buyer wanted it fixed before closing, and the seller needed it done fast.
After
We gave a written price within 24 hours and installed new stainless flashing in one afternoon. We photographed the finished work for the inspector. The sale closed on schedule.
Problems we solve
Chimney Leaks We Fix in Galloway
Flashing failures show up in a handful of predictable ways. Here is what we see most often on Galloway roofs and how we handle each one.
Ask a pro →↗
Tar-patched flashing from a previous roofer
We strip the tar, expose the original flashing detail, and rebuild it correctly with metal. We do not add more tar on top. The result is a code-correct repair that passes inspection and holds through coastal weather.
Lifted counter-flashing after a storm
We reset the counter-flashing into a fresh reglet and fasten it with stainless screws, not nails. If the metal is bent or torn, we replace it. Emergency calls get tarped the same day and repaired within 24 to 48 hours.
Cracked crown letting water behind the flashing
We repair the crown with chimney crown mix and then address the flashing detail. On every flashing call we check the crown, cap, and damper so you are not paying for a second visit a month later.

Most chimney flashing repair in Galloway runs $350 to $950 in 2026, depending on chimney size, roof pitch, and whether we need to reset shingles. Full chimney flashing replacement cost Galloway New Jersey with new copper or stainless steel typically lands between $700 and $1,400. We give you a written price before any work starts.
Thrive Sharp does. We are a Galloway-based chimney company, licensed in New Jersey and CSIA certified, and we handle both repair and full replacement.

The most common causes are rusted-through step flashing, lifted counter-flashing, and tar patches that cracked after a freeze-thaw cycle. Coastal salt air near Smithville and Oceanville speeds up rust. Once the metal fails, water runs down the chase and shows up as a ceiling stain. We trace the exact entry point with an inspection camera before we quote the repair.
Yes, in most cases. If the metal is rusted but the brick and roof deck are sound, we can cut a new reglet and install fresh counter-flashing without a full rebuild. If the flashing has been leaking for years and the masonry is spalling, we may recommend chimney masonry repair or crown work at the same time. We tell you honestly which one you need.
