Chimney Flashing Repair Dumont, NJ
A Dumont roofer can rebuild the flashing around a leaking chimney so the joint between brick and shingles sheds water on its own, so the leak does not come back next season. One call to (551) 374-2031 reaches a nearby roofer who handles chimney flashing.
The joint between a chimney and the roof is one of the most leak-prone spots on any house. Because the chimney and the roof are separate structures, the flashing has to bridge a joint that never stops moving. That is why a single strip of metal glued to the brick with sealant does not last.
A correctly flashed chimney uses a system, not a single piece. An apron covers the downhill face, step flashing pieces weave in with the shingles along both sides, a back pan or cricket handles the uphill side, and counter flashing set into the mortar joints laps down over everything. The counter flashing is where shortcuts usually show up: instead of being cut into the mortar, it is glued to the face of the brick.
Before replacing flashing, it helps to know whether the chimney above the roof is letting water in. A cracked crown, a missing cap, porous brick or failed mortar joints can soak the masonry, and the water then runs down inside the chimney and shows up exactly where a flashing leak would. A roofer checks the flashing and can point out masonry problems that need a mason.
Depending on what the roofer finds, chimney flashing repair in Dumont, NJ can go hand in hand with flashing repair and roof leak repair.

Call nowThe process
The chimney flashing process
Chimney flashing is rebuilt from the bottom up, like the rest of a roof.
Find the source
The roofer looks at the flashing on all four sides, the mortar joints, the crown and cap and the attic framing around the chimney. A hose test on one side at a time can confirm the source.
Strip the old flashing
Shingles around the chimney are removed along with the old flashing, tar and caulk. Rotted sheathing next to the chimney is cut out and renewed.
Set the apron
After a self-adhered membrane wraps the base of the chimney, the apron goes on the downhill face and step pieces are woven up both sides with new shingles. Nothing is fastened to the masonry at this stage, so the roof and chimney can move.
Build a cricket
The upslope side gets a saddle or, for wide chimneys, a small peaked cricket that sheds water to both sides. Building codes call for a cricket behind chimneys wider than about thirty inches across the slope.
Cut in the counter flashing
A groove is cut into the mortar, and the counter flashing is set into it, either in one piece or stepped to follow the slope. The overlap allows movement while keeping water out.
What is included
Parts of a chimney flashing job
Cap flashing
New counter flashing is let into the brick instead of caulked to the face.
Cricket installation
Water and debris are steered around the chimney so water cannot pond against the brick.
Front flashing
A one-piece apron is installed across the downhill face lapped over the shingles below.
Step flashing
Each side gets new step flashing lapped so water runs downhill.

Chimney Flashing Replacement Dumont, NJ
Full replacement of chimney flashing is the answer when the existing pieces are rusted, missing or held on by caulk. When the basic design is wrong, repairs only delay the next leak. Replacement is also the natural time to add a cricket if the chimney lacks one.
The metal choice matters around masonry. Lime in mortar corrodes bare aluminum, so copper, coated steel or coated aluminum are common choices. Ask which metal the roofer plans to use and why.

Chimney Leak Repair Dumont, NJ
Chimney leak repair starts by finding out whether water comes through the flashing or through the chimney itself. Flashing leaks show up during rain at the roof line, often worse on the uphill side, while masonry leaks can appear on any side and may continue for a while after the rain stops as soaked brick drains. Testing the flashing and the masonry separately pins down the source.
If the masonry is the source, the fix may involve the crown, the cap or the brick. A cracked crown needs sealing or rebuilding, a missing cap lets rain straight down the flue, and porous brick can be treated with a breathable water repellent made for masonry. A roofer can point out these problems while checking the flashing.

Chimney Flashing Repair Near Me
Chimney flashing calls in Dumont come mostly from older brick chimneys that have been reflashed with tar more than once. Homes in Dumont and nearby towns like Haworth, New Milford, Bergenfield and Cresskill range from older houses with full masonry chimneys to newer ones with framed chases wrapped in siding, which are flashed more like a sidewall, so it helps to know which kind you have when you call.

Roofs in this climate
Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, building ice dams that push water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. That is why roof repair in Dumont is busiest after a hard winter and before the next one.

Common questions about chimney flashing repair
Who fixes chimney flashing, a roofer or a mason?
Chimney flashing is roofing work, since it ties into the shingles, underlayment and step flashing. Roofers routinely grind the mortar joint and set counter flashing. Problems with the chimney itself, like a cracked crown, call for a mason.
Can chimney flashing be repaired without replacing it?
Small issues, like counter flashing that has pulled out of its mortar joint, can be reset and resealed. If the flashing is corroded or relies on caulk instead of proper lapping, replacing it is the better repair. Adding more tar on top only delays the next leak.
Why does my chimney need a cricket?
A cricket, also called a saddle, is a small peaked structure built behind a chimney on the uphill side. Water flowing down the slope hits the cricket and is steered around both sides. Codes generally require one once a chimney is wider than about thirty inches across the slope.
What causes a chimney leak if the flashing is new?
When new flashing does not stop the leak, the masonry is the usual suspect. A cracked crown, a missing cap, open mortar joints or porous brick can let water travel down inside the masonry to the roof line. In some cases, condensation inside the flue is the cause. Call (551) 374-2031 to have the source traced.
How do I know if my chimney flashing is leaking?
Stains on the ceiling or wall next to the chimney after rain are the most common sign. From the attic, stained rafters and decking around the brick confirm water is getting in. Outside, look for loose or rusted flashing and old sealant patches. Call (551) 374-2031 to have a roofer check it.
