Counter flashing
Cap flashing on masonry is reset into the mortar joint so the top edge of the step flashing stays covered.

Flashing Repair Cresskill, NJ
Most leaks at walls, dormers and roof edges in Cresskill come down to flashing, and a roofer can fix it by replacing the failed metal rather than caulking over it, woven correctly with the shingles and tucked behind the siding. One call to (551) 395-0321 reaches a nearby roofer who repairs flashing.
Shingles handle the open field of a roof; flashing handles the joints. Step flashing is a series of small bent pieces woven in with each course of shingles along a sidewall, counter flashing laps over it from the wall side, a kickout at the bottom of the wall throws water into the gutter, and drip edge lines the eaves and rakes. A single missing or loose piece is enough to send water behind the shingles or into the wall.
A failed kickout or step flashing tends to rot wall sheathing long before it stains a ceiling. At the base of a roof-to-wall joint, water with nowhere to go runs behind siding and soaks the wall framing. That is why flashing deserves a close look on any house with walls rising above a roof.
A bead of sealant along a joint is a warning sign, not a repair. Roofing cement and caulk shrink, crack and pull away under sun and temperature swings, then let water in again. A real repair replaces the metal, often by removing a few courses of siding and shingles so the new flashing can be lapped correctly.
Many flashing repair calls in Cresskill also turn up a need for chimney flashing repair or roof leak repair.

How flashing repair works
Flashing repair is a layering job, done from the bottom up.
Inspect the joint
The flashing is checked along its full length, from the eave up, along with the wall sheathing where it can be seen. Soft siding or stained trim below the joint suggests the wall needs a look too.
Expose the old metal
Siding is lifted or removed along the joint so the old flashing and housewrap can be reached. That is the only way to lap new metal behind the wall weather barrier.
Install new flashing
Fresh step flashing goes in course by course with the shingles, starting with a kickout at the eave. Each piece is nailed through the roof side only, so the wall and roof can move independently.
Add counter flashing
On masonry walls, counter flashing is set into a cut joint; on framed walls, the housewrap and siding cover the flashing. That clearance keeps the siding from soaking up water at the roof line.
Finish the edges
Damaged drip edge is renewed so water drips clear of the fascia. At eaves the underlayment goes over the drip edge; at rakes the drip edge goes over it.

Roof Flashing Repair Cresskill, NJ
Roof flashing repair ranges from resetting a single loose piece to rebuilding a full sidewall. A lifted counter flashing on a masonry wall may only need resetting into the mortar joint, while a leaking sidewall usually means new step flashing, new shingles along the wall and some siding work. Knowing the scope up front avoids surprises once siding comes off.
Not every flashing metal works in every spot. Aluminum is common and easy to form, galvanized steel is stiffer, and copper lasts a very long time; aluminum should not sit directly against fresh mortar or certain treated lumber, which can corrode it. Mixing copper with aluminum or galvanized metal in contact can cause corrosion, so the roofer matches the metal to what is already there.

Roof Valley Flashing Cresskill, NJ
A valley is where two roof slopes meet, and it channels a large share of the roof water toward the eave. An open valley uses a strip of metal, often a W-shaped valley pan with a center rib, with the shingles cut back on each side; a closed valley has the shingles woven or cut across it with no metal showing. Both need ice and water shield underneath, centered in the valley.
Valley leaks often come from debris, worn shingles or nails driven too close to the center. Small installation details, like clipping the upper corners of the cut shingles, keep water flowing down the valley instead of across it. A valley that leaks is generally rebuilt rather than patched.

Flashing Repair Near Me
Around Cresskill, flashing leaks tend to show up wherever a roof runs into a wall, a dormer or a skylight. Across Cresskill and nearby communities including Demarest, Tenafly, Dumont and Closter, the age of the house and the number of roof-to-wall joints decide how much flashing work is likely, so a close look at every joint is worth asking for.

What the local climate does to a roof
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, which is how ice dams form and back water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Cresskill is busiest after a hard winter and before the next one.

Flashing Repair questions
Is it possible to fix flashing without a new roof?
Most flashing problems are fixed without touching the rest of the roof. Only the shingles and siding next to the joint come off while new metal goes in. If the roof is near the end of its life, it can make sense to replace flashing as part of a reroof instead.
How do I know if my flashing is leaking?
Leaks near walls, dormers, skylights or valleys are the strongest sign. Outside, check for metal that has pulled away, rust holes and old sealant patches. Rot at the base of a sidewall suggests water is getting behind the siding. Call (551) 395-0321 to have a roofer check it.
Can I just seal the flashing with caulk?
Caulk can slow a flashing leak but almost never fixes it. Over time, it hardens, splits and lets the joint leak again, often worse than before. A proper repair replaces the metal so it sheds water without depending on sealant.
Why does my roof need kickout flashing?
A kickout is a small diverter at the bottom of a roof-to-wall joint, where the roof edge ends against a wall. It throws runoff away from the wall and into the gutter. Missing kickouts are a common cause of hidden wall rot.
What is step flashing and why does it matter?
Step flashing uses individual bent pieces that interleave with each shingle course. Because each piece laps the one below, water is passed down the wall joint from piece to piece and onto the roof. A long single strip sends water under the roofing, which is why step pieces are the standard.
