Rot repair
Rotted decking around the chimney opening is replaced while the area is open.
A roofer in Randolph 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) 858-1826 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. 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. 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.
Water near a chimney can also come through the chimney itself. 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.
Depending on what the roofer finds, chimney flashing repair in Randolph, NJ can go hand in hand with flashing repair and roof leak repair.

Call nowHere is how a roofer typically handles chimney flashing.
The roofer looks at the flashing on all four sides, the mortar joints, the crown and cap and the attic framing around the chimney. If the masonry is clearly the source, the roofer will say so.
Old flashing and sealant come off, and the shingles next to the brick are lifted or removed. Soft or rotted decking around the chimney is replaced at this stage.
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.
The upslope side gets a saddle or, for wide chimneys, a small peaked cricket that sheds water to both sides. Wide chimneys need a cricket under most residential codes.
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. The overlap allows movement while keeping water out.

Water and debris are steered around the chimney and covered with metal or membrane and shingles.
Step pieces up both sides of the chimney are replaced one piece per course.
Cap flashing is cut into the masonry instead of caulked to the face.
The base flashing on the front is renewed to shed water onto the roof.
Full replacement of chimney flashing is the answer when the existing pieces are rusted, missing or held on by caulk. If the original flashing was installed incorrectly, more sealant cannot correct the lapping. Adding a cricket during replacement solves the uphill pooling at the same time.
Chimney flashing has to tolerate mortar and moisture for decades. 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.
A chimney can leak at the roof line or from the top down, and the fix is different for each. A leak that keeps going after the rain ends often means water stored in the masonry is draining out. Testing the flashing and the masonry separately pins down the source.
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. Those repairs are often done alongside new flashing so the whole leak is solved.
Chimney flashing calls in Randolph come mostly from older brick chimneys that have been reflashed with tar more than once. From Randolph out to neighboring towns such as Dover, Wharton, Succasunna and Rockaway, 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, which is why the roofer starts by looking at how the chimney is built.

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. Most homeowners in Randolph, NJ have the roof checked in the fall and again after the snow melts.
Small roof problems caught early usually stay small repairs.
