Chimney Flashing Repair Sparta, NJ
A roofer in Sparta 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. Dial (973) 858-1854 to talk with a local roofer about the chimney leak.
The joint between a chimney and the roof is one of the most leak-prone spots on any house. 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. 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. 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. 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. A cracked crown, a missing cap, porous brick or failed mortar joints can soak the masonry, and the water then runs down inside the chimney and shows up exactly where a flashing leak would. Sorting out which one is leaking avoids paying for the wrong repair.
Many chimney flashing repair calls in Sparta also turn up a need for flashing repair or roof leak repair.

What happens during chimney flashing repair
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. A hose test on one side at a time can confirm the source.
Strip the old flashing
Shingles around the chimney are removed along with the old flashing, tar and caulk. Soft or rotted decking around the chimney is replaced at this stage.
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.
Build a cricket
Behind the chimney, a metal back pan or a framed cricket keeps water and debris from piling up. Without one, a wide chimney acts like a dam.
Cut in the 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
Chimney flashing parts
Step flashing
Side flashing is woven in with new shingles lapped so water runs downhill.
Counter flashing
Counter flashing is set into ground-out mortar joints instead of caulked to the face.
Apron flashing
A one-piece apron is installed across the downhill face lapped over the shingles below.
Cricket installation
A saddle diverts water around the uphill side and covered with metal or membrane and shingles.

Chimney Flashing Replacement Sparta, NJ
Full replacement of chimney flashing is the answer when the existing pieces are rusted, missing or held on by caulk. Patching a system that was installed wrong rarely works, because the problem is in how the pieces overlap. 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. The roofer can explain the options that suit your chimney.

Chimney Leak Repair Sparta, NJ
Leaks around a chimney have two main sources: the flashing at the roof and the masonry above it. 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. Testing the flashing and the masonry separately pins down the source.
When water comes through the chimney, the repair moves up above the roof. 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 Sparta come mostly from older brick chimneys that have been reflashed with tar more than once. Across Sparta and nearby communities including Lake Hopatcong, Hopatcong, Andover and Newton, the chimney type decides the fix: masonry needs counter flashing cut into the brick, and a framed chase needs step flashing behind the siding, so it helps to know which kind you have when you call.
For chimney flashing repair in Sparta, NJ or nearby towns like Lake Hopatcong, Hopatcong, Andover and Newton, call (973) 858-1854 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. 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 Sparta, NJ have the roof checked in the fall and again after the snow melts.

Chimney Flashing Repair FAQ
Why does my chimney need a 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.
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.
Is it possible to just reseal chimney flashing?
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. More sealant over a failing system buys a little time at best.
Why is my chimney still leaking after new flashing?
A leak that continues after new flashing usually comes from the chimney itself. 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. Call (973) 858-1854 to reach a roofer.
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. From the attic, stained rafters and decking around the brick confirm water is getting in. From the yard, heavy tar around the base is a good hint that the flashing has been patched before. Call (973) 858-1854 to have a roofer check it.
