Flashing Repair Millburn, NJ
A Millburn roofer can stop leaks where the roof meets a wall, dormer, skylight or edge by renewing the flashing at that joint, woven correctly with the shingles and tucked behind the siding. Call (973) 858-1841 to reach a local roofer.
Flashing is the thin metal that seals every place the roof surface is interrupted. 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. When any piece is missing, loose or rusted through, water gets behind the roof covering.
Flashing leaks are sneaky because the water often runs into the wall instead of the attic. 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. Sealant smeared where flashing should be dries and cracks in a few seasons, and it can trap water instead of shedding it. Proper flashing sheds water by gravity and lapping, so it keeps working even after any sealant ages.
If the problem goes deeper than it first looked, a Millburn roofer may also recommend chimney flashing repair or roof leak repair.

How flashing repair works
Flashing repair is a layering job, done from the bottom up.
Check the flashing
The roofer checks the joint from the roof and the attic, looking for missing pieces, rust, face nails and caulk hiding a gap. Soft siding or stained trim below the joint suggests the wall needs a look too.
Open the joint
The shingles next to the wall come up, and the lowest siding courses come off to expose the flashing. Working the new pieces in correctly depends on access behind the siding.
Replace the pieces
Each new step piece overlaps the one beneath it, and the kickout at the base sends water into the gutter. Fasteners go into the roof deck only, never through the vertical leg into the wall.
Seal the wall side
On masonry walls, counter flashing is set into a cut joint; on framed walls, the housewrap and siding cover the flashing. Siding pressed tight to the shingles stays wet and rots.
Seal the eaves
Drip edge along eaves and rakes is checked and replaced where it is bent or missing, lapped correctly with the underlayment. At eaves the underlayment goes over the drip edge; at rakes the drip edge goes over it.
What is included
Flashing a roofer can repair
Step flashing
Sidewall flashing is rebuilt one course at a time and woven with new shingles.
Cap flashing
Counter flashing over step pieces is refitted or replaced so the top edge of the step flashing stays covered.
Edge flashing
Edge metal is renewed along the roof perimeter so water drips clear of the fascia.
Diverter flashing
A kickout is added where a roof edge ends against a wall to steer water into the gutter.

Roof Flashing Repair Millburn, NJ
Roof flashing repair ranges from resetting a single loose piece to rebuilding a full sidewall. Some repairs take an hour at one corner; others mean opening a whole wall joint and replacing the metal course by course. 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. Matching metals avoids corrosion where new and old flashing meet.

Roof Valley Flashing Millburn, NJ
Roof valleys carry the runoff from two slopes, so they handle more water than any other part of the roof. In an open valley, a band of metal stays exposed down the center, while in a closed or woven valley the shingles cover the valley and the underlayment beneath does the heavy lifting. A peel-and-stick underlayment down the valley is the backup layer in both styles.
Common valley problems include rusted metal, debris dams, worn shingles and nails placed too close to the centerline. Shingle corners cut square instead of clipped at the top can also steer water sideways under the valley shingles. Fixing a valley usually involves stripping it, relining it and installing new metal or reshingling.

Roofs in this climate
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. 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. That is why roof repair in Millburn is busiest after a hard winter and before the next one.

Flashing Repair FAQ
What is step flashing and why does it matter?
Along a sidewall, each shingle course gets its own small flashing piece that overlaps the one below. Because each piece laps the one below, water is passed down the wall joint from piece to piece and onto the roof. A single long strip of metal along a wall cannot do that and tends to channel water behind the shingles.
How do I know if my flashing is leaking?
Water showing up near a wall joint, skylight or valley points to flashing. From outside, rusted, loose or caulked-over flashing is a warning sign. Rot at the base of a sidewall suggests water is getting behind the siding. Call (973) 858-1841 to reach a roofer.
Will caulk fix leaking flashing?
A bead of caulk may hold for a season or two, but it will fail. Over time, it hardens, splits and lets the joint leak again, often worse than before. Real repairs use new metal lapped in the right order.
Why does my roof need kickout flashing?
Kickout flashing sits where a roof eave dies into a sidewall. Its job is to keep the water coming down the joint off the siding and out of the wall. Without one, the wall below that joint often rots quietly for years.
Is it possible to fix flashing without a new roof?
Most flashing problems are fixed without touching the rest of the roof. The work stays local to the joint, with new shingles woven in along it. On an old roof, it may be smarter to plan the flashing with a full replacement.
