Chimney Flashing Repair Leonia, NJ
Most leaks around a chimney in Leonia come from the flashing, and a roofer can fix them with new step and counter flashing set into the brick instead of tar, with a cricket behind wide chimneys to keep water from piling up. Call (551) 348-8956 to reach a local roofer.
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. Any flashing that is rigidly glued to both the brick and the roof tends to crack loose within a few years.
Each side of a chimney gets its own kind of flashing. The front gets an apron, the sides get step flashing, the back gets a pan or cricket, and counter flashing tucked into the brick seals the top of it all. 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.
Water near a chimney can also come through the chimney itself. 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. Sorting out which one is leaking avoids paying for the wrong repair.
Many chimney flashing repair calls in Leonia also turn up a need for flashing repair or roof leak repair.

Call nowThe process
The chimney flashing process
The work follows the path water takes, front to back.
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.
Clear the joint
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.
Add step flashing
Ice and water shield goes down first, then the apron across the front and step flashing up each side, one piece per shingle course. Each step piece laps the one below it.
Handle the back side
On the uphill side, a back pan or saddle is fitted, and on wider chimneys a cricket is framed to split the water around it. Building codes call for a cricket behind chimneys wider than about thirty inches across the slope.
Set 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.

Chimney Flashing Replacement Leonia, 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. It is also the right moment to add a cricket or back pan.
The metal choice matters around masonry. Lime in mortar corrodes bare aluminum, so copper, coated steel or coated aluminum are common choices. The roofer can explain the options that suit your chimney.

Chimney Leak Repair Leonia, 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.
Leaks through the chimney body need masonry work rather than flashing. 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
In Leonia, many chimney flashing problems show up on homes with wide brick chimneys and no cricket behind them. Across Leonia and nearby communities including Palisades Park, Fort Lee, Ridgefield Park and Englewood, the chimney type decides the fix: masonry needs counter flashing cut into the brick, and a framed chase needs step flashing behind the siding, which is why the roofer starts by looking at how the chimney is built.

How the weather here affects roofs around Leonia
Cold winters bring snow, ice and a long stretch of freezing nights. When warm attic air melts the snow, the meltwater runs down and freezes again at the 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 Leonia is busiest after a hard winter and before the next one.

Common questions about chimney flashing repair
What are the signs of a chimney flashing leak?
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. From the yard, heavy tar around the base is a good hint that the flashing has been patched before. Call (551) 348-8956 to reach a local roofer.
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. Flashing that was installed wrong or has rusted through needs to be replaced, not resealed. More sealant over a failing system buys a little time at best.
Who fixes chimney flashing, a roofer or a mason?
The flashing belongs to the roof, so a roofer is the right call for it. Roofers routinely grind the mortar joint and set counter flashing. Problems with the chimney itself, like a cracked crown, call for a mason.
Why is my chimney still leaking after new flashing?
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. A call to (551) 348-8956 is a good next step.
Why does my chimney need a cricket?
It is a little roof-like peak that sits behind the chimney. 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.
