Flashing Repair Tenafly, NJ
A Tenafly roofer can stop leaks where the roof meets a wall, dormer, skylight or edge by renewing the flashing at that joint, with the wall sheathing checked for hidden rot. Call (551) 355-3330 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. Each of those pieces has one job, and when it fails, water finds the gap.
Flashing leaks are sneaky because the water often runs into the wall instead of the attic. A missing kickout is a classic example: water running down the roof edge pours behind the siding at the bottom of the wall, and the rot shows up later as soft trim, stained siding or a damp window below. Catching it early keeps the repair to the flashing instead of the wall.
One of the most common shortcuts on roofs is caulk in place of metal. Sealant can hold for a while, but it fails sooner or later, and the joint leaks once more. A real repair replaces the metal, often by removing a few courses of siding and shingles so the new flashing can be lapped correctly.
Depending on what the roofer finds, flashing repair in Tenafly, NJ can go hand in hand with chimney flashing repair and roof leak repair.

How flashing repair works
Here is how a roofer typically approaches a flashing repair.
Inspect the joint
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.
Expose the old metal
To replace step flashing properly, a few courses of siding and the shingles along the wall are carefully removed. New flashing has to tuck behind the housewrap, which means opening the wall a little.
Weave in the metal
New step flashing is installed one piece per shingle course, each lapping the one below, with a kickout diverter at the bottom. Each piece is nailed through the roof side only, so the wall and roof can move independently.
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. That clearance keeps the siding from soaking up water at the roof line.
Check drip edge
At the roof edges, drip edge is reset or replaced to protect the fascia and deck edge. Correct laps at the edges keep water out of the fascia and soffit.

Roof Flashing Repair Tenafly, 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.
Material matters too. Copper, galvanized steel and aluminum all show up on roofs, and each has spots where it works best. Dissimilar metals touching each other corrode, so repairs should match existing flashing or be separated.

Roof Valley Flashing Tenafly, NJ
Valleys are the gutters of the roof surface, collecting water from both sides. Valleys are either open, with exposed metal, or closed, with shingles running through them. A peel-and-stick underlayment down the valley is the backup layer in both styles.
Valley leaks often come from debris, worn shingles or nails driven too close to the center. Shingle corners cut square instead of clipped at the top can also steer water sideways under the valley shingles. Valley repair usually means removing the shingles along the valley, replacing the membrane and metal and reshingling with the right cuts.

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. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Tenafly, NJ have the roof checked in the fall and again after the snow melts.

Common questions about flashing repair
Will caulk fix leaking flashing?
Sealant is a short-term patch for flashing, not a lasting repair. Sun and temperature swings crack it, and water gets behind it again, sometimes trapped where it rots wood faster. 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. It throws runoff away from the wall and into the gutter. Leaving it out is one of the most common causes of rot in the wall under a roof edge.
How do I know if my flashing is leaking?
Leaks near walls, dormers, skylights or valleys are the strongest sign. Outside, look for rust, gaps, lifted metal, nails through the face and heavy caulk along the joint. Soft or stained siding at the bottom of a sidewall often means a missing kickout. Call (551) 355-3330 to reach a roofer.
Why does flashing need to be woven with the shingles?
Step flashing is a series of small L-shaped pieces, one for each course of shingles along a wall. That layering means every piece sheds water onto the shingle below it, the same way the shingles shed water down the roof. A single long strip of metal along a wall cannot do that and tends to channel water behind the shingles.
Is it possible to fix flashing without a new roof?
Flashing repair is a routine job on roofs that are otherwise sound. The roofer removes the shingles and siding along the joint, installs new flashing and reshingles that strip. For a worn-out roof, combining the work with a replacement avoids doing the joint twice.
