Chimney Flashing Repair Pequannock, NJ
A Pequannock 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. Call (862) 458-0110 to reach a local roofer.
Few places on a roof leak as often as the gap around a chimney. 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. 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. Counter flashing that is only caulked onto the brick face is one of the most common causes of chimney leaks.
Water near a chimney can also come through the chimney itself. Leaks that continue after new flashing often trace back to the crown, the cap or the brick itself. A careful look covers both the flashing and the visible masonry above it.
Many chimney flashing repair calls in Pequannock also turn up a need for flashing repair or roof leak repair.

Call nowThe process
What happens during chimney flashing repair
The work follows the path water takes, front to back.
Check the joint
Before anything comes off, the roofer checks the flashing, the brick, the crown and the wood around the chimney. A hose test on one side at a time can confirm the source.
Remove old metal
Shingles around the chimney are removed along with the old flashing, tar and caulk. Any decking that has gone soft from years of leaks is replaced.
Add step flashing
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.
Install the back pan
Behind the chimney, a metal back pan or a framed cricket keeps water and debris from piling up. Wide chimneys need a cricket under most residential codes.
Cut in the counter flashing
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

Side flashing is woven in with new shingles nailed to the deck, not the brick.
Apron flashing
A one-piece apron is installed across the downhill face with counter flashing over it.
Rot repair
Water-damaged wood at the chimney is cut out before the new flashing goes in.
Chimney saddle

Chimney Flashing Replacement Pequannock, 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. Matching the metal to the masonry avoids early corrosion.

Chimney Leak Repair Pequannock, 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. A careful water test, one side at a time, can tell the two apart.
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
In Pequannock, many chimney flashing problems show up on homes with wide brick chimneys and no cricket behind them. From Pequannock out to neighboring towns such as Pompton Plains, Lincoln Park, Towaco and Riverdale, 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, so expect the roofer to ask which type is on your house.

What the local climate does to a roof
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, 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. That is why roof repair in Pequannock is busiest after a hard winter and before the next one.

Chimney Flashing Repair questions
How do I know if my chimney flashing is leaking?
Water marks beside the chimney inside the house are the usual first clue. From the attic, stained rafters and decking around the brick confirm water is getting in. On the roof, rusted metal, loose counter flashing and heavy tar are warning signs. Call (862) 458-0110 to reach a local roofer.
What causes a chimney leak if the flashing is new?
Water can still get in through the top or sides of the chimney. 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 (862) 458-0110 is a good next step.
Who fixes chimney flashing, a roofer or a mason?
The flashing belongs to the roof, so a roofer is the right call for it. 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.
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. Another coat of tar is a short-term patch.
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. Wide chimneys need one under most building codes.
