Chimney Flashing Repair Tenafly, NJ
A roofer in Tenafly can stop most chimney leaks by replacing the flashing where the chimney meets the roof: step flashing along the sides, counter flashing cut into the mortar, an apron at the front and a back pan or cricket behind, with a cricket behind wide chimneys to keep water from piling up. Call (551) 355-3330 to reach a local roofer.
Few places on a roof leak as often as the gap around a chimney. 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. 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.
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. Sorting out which one is leaking avoids paying for the wrong repair.
Depending on what the roofer finds, chimney flashing repair in Tenafly, NJ can go hand in hand with flashing repair and roof leak repair.

Call nowThe process
What happens during chimney flashing repair
The work follows the path water takes, front to back.
Inspect the chimney
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
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.
Handle the back side
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.
Set counter flashing
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.

Chimney Flashing Replacement Tenafly, 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.
Not every flashing metal suits brick. Copper is a long-lasting choice for counter flashing, while aluminum needs protection from contact with lime in the mortar. Matching the metal to the masonry avoids early corrosion.

Chimney Leak Repair Tenafly, 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. Hose testing each side and then the chimney top separately settles the question.
If the masonry is the source, the fix may involve the crown, the cap or the brick. Typical fixes are crown repair, a new cap and repointing of open mortar joints, sometimes followed by a vapor-permeable masonry water repellent. Those repairs are often done alongside new flashing so the whole leak is solved.

Chimney Flashing Repair Near Me
Around Tenafly, chimney leaks often date back to a reroof where the old chimney flashing was reused or covered in sealant. From Tenafly out to neighboring towns such as Cresskill, Englewood, Englewood Cliffs and Demarest, 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 it helps to know which kind you have when you call.
For chimney flashing repair in Tenafly, NJ or nearby towns like Cresskill, Englewood, Englewood Cliffs and Demarest, call (551) 355-3330 to reach a roofer who covers your street.
What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder 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 Tenafly, NJ have the roof checked in the fall and again after the snow melts.

Chimney Flashing Repair questions
What causes a chimney leak if the flashing is new?
Water can still get in through the top or sides of the chimney. Rain soaks through porous brick or a cracked crown and runs down inside the chimney. Condensation in an unlined or oversized flue can also cause damp spots. A call to (551) 355-3330 is a good next step.
How do I know if my chimney flashing is leaking?
Water marks beside the chimney inside the house are the usual first clue. 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) 355-3330 to reach a local roofer.
Is it possible to just reseal chimney flashing?
Minor problems such as a loose counter flashing piece can be refastened into the mortar. 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.
Should a roofer or a mason repair my chimney flashing?
A roofer handles the flashing, because it has to be woven into the roof. Roofers routinely grind the mortar joint and set counter flashing. If the crown, cap or brick is damaged, a mason handles that part.
What is a chimney cricket?
A cricket, also called a saddle, is a small peaked structure built behind a chimney on the uphill side. It splits the water and debris coming down the roof and sends them around the chimney instead of letting them pile up against the brick. Wide chimneys need one under most building codes.
