Chimney Flashing Repair Fairview, NJ
Most leaks around a chimney in Fairview come from the flashing, and a roofer can fix them with new step and counter flashing set into the brick instead of tar, and check whether the crown or brick is part of the problem. Call (551) 378-0045 to reach a local roofer.
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. 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. 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. Counter flashing is the piece that most often fails or is skipped, replaced by surface-mounted metal and a bead of caulk.
Not every leak around a chimney is a flashing leak. 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.
If the problem goes deeper than it first looked, a Fairview roofer may also recommend flashing repair or roof leak repair.

How chimney flashing repair works
Here is how a roofer typically handles chimney flashing.
Find the source
Every side of the chimney is checked, along with the masonry above the roof and the decking around the opening from the attic. That separates true flashing leaks from water coming through the chimney itself.
Clear the joint
The roofer removes the existing metal, layers of tar and the nearby shingles. Rotted sheathing next to the chimney is cut out and renewed.
Set the apron
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.
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.
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.
What is included
What chimney flashing repair covers
Side flashing
Each side gets new step flashing lapped so water runs downhill.
Counter flashing
New counter flashing is let into the brick so it overlaps the step flashing.
Decking repair
Soft sheathing next to the chimney is renewed so the shingles have solid nailing.
Chimney saddle
A saddle diverts water around the uphill side which stops one of the most common chimney leaks.

Chimney Flashing Replacement Fairview, NJ
Chimney flashing replacement makes sense when the metal is rusted, the counter flashing is only glued to the brick or the joint has been tarred over several times. Patching a system that was installed wrong rarely works, because the problem is in how the pieces overlap. It is also the right moment to add a cricket or back pan.
Not every flashing metal suits brick. Copper and lead-coated copper last a very long time and form neatly to brick, galvanized steel is durable when painted, and aluminum should be coated or kept out of direct contact with mortar, which can corrode it. Matching the metal to the masonry avoids early corrosion.

Chimney Leak Repair Fairview, 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. Hose testing each side and then the chimney top separately settles the question.
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. Those repairs are often done alongside new flashing so the whole leak is solved.

Around Fairview, chimney leaks often date back to a reroof where the old chimney flashing was reused or covered in sealant. From Fairview out to neighboring towns such as Cliffside Park, Ridgefield, Edgewater and Palisades Park, 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.

How the weather here affects roofs around Fairview
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, 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. Most homeowners in Fairview, NJ have the roof checked in the fall and again after the snow melts.

Chimney Flashing Repair FAQ
Is it possible to just reseal chimney flashing?
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. More sealant over a failing system buys a little time at best.
What are the signs of a chimney flashing leak?
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 (551) 378-0045 to have a roofer check it.
Why is my chimney still leaking after new flashing?
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. Sometimes moisture inside the flue itself is to blame. A call to (551) 378-0045 is a good next step.
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.
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. Problems with the chimney itself, like a cracked crown, call for a mason.
