Decking repair
Soft sheathing next to the chimney is renewed so the shingles have solid nailing.
A Newton 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. Dial (973) 858-9950 to talk with a local roofer about the chimney leak.
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. That is why a single strip of metal glued to the brick with sealant does not last.
A correctly flashed chimney uses a system, not a single piece. 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. Counter flashing is the piece that most often fails or is skipped, replaced by surface-mounted metal and a bead of caulk.
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. A careful look covers both the flashing and the visible masonry above it.
Many chimney flashing repair calls in Newton also turn up a need for flashing repair or roof leak repair.

Call nowChimney flashing is rebuilt from the bottom up, like the rest of a roof.
Before anything comes off, the roofer checks the flashing, the brick, the crown and the wood around the chimney. That separates true flashing leaks from water coming through the chimney itself.
Old flashing and sealant come off, and the shingles next to the brick are lifted or removed. Any decking that has gone soft from years of leaks is replaced.
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.
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.
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.

New counter flashing is let into the brick and sealed at the joint.
Step pieces up both sides of the chimney are replaced lapped so water runs downhill.
A saddle diverts water around the uphill side and covered with metal or membrane and shingles.
The base flashing on the front is renewed lapped over the shingles below.
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. 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. Ask which metal the roofer plans to use and why.
Leaks around a chimney have two main sources: the flashing at the roof and the masonry above it. A leak that keeps going after the rain ends often means water stored in the masonry is draining out. A careful water test, one side at a time, can tell the two apart.
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. The roofer can spot many of these from the roof and tell you who should fix them.
Chimney flashing calls in Newton come mostly from older brick chimneys that have been reflashed with tar more than once. Across Newton and nearby communities including Andover, Hopatcong, Allamuchy and Franklin, 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 expect the roofer to ask which type is on your house.

Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder 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 Newton, NJ have the roof checked in the fall and again after the snow melts.
A roof problem fixed early rarely spreads to the decking, the insulation or the ceilings.
Roofers in Newton know the roof types and weather wear common in local homes.
