Chimney Flashing Repair Emerson, NJ
A Emerson 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) 398-0015 reaches a nearby roofer who handles chimney flashing.
A chimney is a large masonry box punched through the roof, and sealing around it takes several pieces of flashing working together. The brick and the roof framing move independently as the house settles and seasons change, so the seal between them has to allow for movement. Tar and caulk alone cannot handle that movement for long.
Proper chimney flashing has four main parts. 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. Brick and mortar absorb rain, and a cracked crown or open joints can let water travel down through the masonry to the roof line. Sorting out which one is leaking avoids paying for the wrong repair.
Chimney Flashing Repair is often paired with flashing repair and roof leak repair, depending on the cause.

How chimney flashing repair works
Here is how a roofer typically handles chimney flashing.
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. That separates true flashing leaks from water coming through the chimney itself.
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
A membrane underlayment goes around the chimney, then the front apron and the side step flashing are installed with the shingles. Each step piece laps the one below it.
Install the back pan
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.
Seal the top edge
Counter flashing is let into a ground-out mortar joint and sealed, overlapping the base flashing below. The overlap allows movement while keeping water out.
What is included
What chimney flashing repair covers
Rot repair
Water-damaged wood at the chimney is cut out so the shingles have solid nailing.
Cricket installation
A cricket is framed behind wide chimneys so water cannot pond against the brick.
Counter flashing
Counter flashing is set into ground-out mortar joints instead of caulked to the face.
Step flashing
Each side gets new step flashing lapped so water runs downhill.

Chimney Flashing Replacement Emerson, 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. Adding a cricket during replacement solves the uphill pooling at the same time.
The metal choice matters around masonry. 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 Emerson, NJ
A chimney can leak at the roof line or from the top down, and the fix is different for each. 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. 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. Crown cracks, open joints and missing caps are repaired by a mason, and a breathable sealer can cut down how much water the brick absorbs. The roofer can spot many of these from the roof and tell you who should fix them.

Chimney Flashing Repair Near Me
In Emerson, many chimney flashing problems show up on homes with wide brick chimneys and no cricket behind them. From Emerson out to neighboring towns such as Westwood, Oradell, Haworth and Hillsdale, 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.

Roofs in this climate
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, which is how ice dams form and back water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Emerson, NJ have the roof checked in the fall and again after the snow melts.

Chimney Flashing Repair questions
How do I know if my chimney flashing is leaking?
Look for damp spots near the chimney after rain, both in the house and in the attic. In the attic, wet or dark framing around the chimney opening points the same way. Outside, look for loose or rusted flashing and old sealant patches. Call (551) 398-0015 to have a roofer check it.
What is a chimney 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. Most residential codes call for one behind chimneys wider than about thirty inches.
Can chimney flashing be repaired without replacing it?
A single loose section of counter flashing can be reset without replacing everything. If the flashing is corroded or relies on caulk instead of proper lapping, replacing it is the better repair. Another coat of tar is a short-term patch.
Why is my chimney still leaking after new flashing?
When new flashing does not stop the leak, the masonry is the usual suspect. Rain soaks through porous brick or a cracked crown and runs down inside the chimney. Sometimes moisture inside the flue itself is to blame. A call to (551) 398-0015 is a good next step.
Should a roofer or a mason repair my chimney flashing?
Chimney flashing is roofing work, since it ties into the shingles, underlayment and step flashing. Cutting the counter flashing into the mortar joint is part of that job. Damage to the crown, brick or mortar beyond that is masonry work.
