Chimney Flashing Repair Lodi, NJ
A Lodi roofer can rebuild the flashing around a leaking chimney so the joint between brick and shingles sheds water on its own, and check whether the crown or brick is part of the problem. One call to (551) 394-0610 reaches a nearby roofer who handles chimney flashing.
Few places on a roof leak as often as the gap around a chimney. Masonry and wood framing expand, shrink and settle at different rates, which is why chimney flashing is built in two parts that can slide past each other. Tar and caulk alone cannot handle that movement for long.
A correctly flashed chimney uses a system, not a single piece. Along the front sits a one-piece apron, step pieces run up each side with the shingles, a saddle or cricket diverts water behind, and counter flashing ground into the mortar covers the top edges. 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. Brick and mortar absorb rain, and a cracked crown or open joints can let water travel down through the masonry to the roof line. 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 Lodi, 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.
Check the joint
Before anything comes off, the roofer checks the flashing, the brick, the crown and the wood around the chimney. If the masonry is clearly the source, the roofer will say so.
Remove old metal
The roofer removes the existing metal, layers of tar and the nearby shingles. Any decking that has gone soft from years of leaks is replaced.
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. The step flashing is nailed to the roof deck only, never to the brick.
Build a cricket
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. Without one, a wide chimney acts like a dam.
Seal the top edge
The roofer grinds a slot into a mortar joint, bends the counter flashing into it and seals it, so it laps down over the step flashing. That two-part design lets the chimney and roof move without tearing the seal.
What is included
What chimney flashing repair covers
Apron flashing
A one-piece apron is installed across the downhill face to shed water onto the roof.
Side flashing
Step pieces up both sides of the chimney are replaced lapped so water runs downhill.
Chimney saddle
A saddle diverts water around the uphill side so water cannot pond against the brick.
Cap flashing
New counter flashing is let into the brick instead of caulked to the face.

Chimney Flashing Replacement Lodi, 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.
Not every flashing metal suits brick. Lime in mortar corrodes bare aluminum, so copper, coated steel or coated aluminum are common choices. Matching the metal to the masonry avoids early corrosion.

Chimney Leak Repair Lodi, NJ
Chimney leak repair starts by finding out whether water comes through the flashing or through the chimney itself. Water that appears only in hard rain at the base points to flashing, while a slow leak that lingers after rain hints at soaked brick or a cracked crown. A careful water test, one side at a time, can tell the two apart.
Leaks through the chimney body need masonry work rather than flashing. Typical fixes are crown repair, a new cap and repointing of open mortar joints, sometimes followed by a vapor-permeable masonry water repellent. A roofer can point out these problems while checking the flashing.

Chimney Flashing Repair Near Me
Chimney flashing calls in Lodi come mostly from older brick chimneys that have been reflashed with tar more than once. From Lodi out to neighboring towns such as Hasbrouck Heights, Garfield, Maywood and Hackensack, older brick chimneys tend to need counter flashing reset into worn mortar, while newer framed chases more often leak at the chase top or siding joint, which is why the roofer starts by looking at how the chimney is built.

How the weather here affects roofs around Lodi
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. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Lodi 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. In the attic, wet or dark framing around the chimney opening points the same way. From the yard, heavy tar around the base is a good hint that the flashing has been patched before. Call (551) 394-0610 to have a roofer check it.
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. Condensation in an unlined or oversized flue can also cause damp spots. A call to (551) 394-0610 is a good next step.
Who fixes chimney flashing, a roofer or a mason?
A roofer handles the flashing, because it has to be woven into the roof. 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?
A single loose section of counter flashing can be reset without replacing everything. When the metal is rusted, missing pieces or was never installed correctly, replacement is the lasting fix. Adding more tar on top only delays the next leak.
Why does my chimney need a cricket?
A cricket is a small ridge framed on the upslope side of a 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.
