Flashing Repair Rahway, NJ
A Rahway 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 (908) 562-6861 to reach a local roofer.
Wherever a roof meets a wall, a dormer, a skylight, a valley or an edge, it relies on flashing to keep water out. The main types are step flashing at sidewalls, apron flashing at headwalls, counter flashing over the top, kickouts at the bottom of walls, valley metal and drip edge at the edges. When any piece is missing, loose or rusted through, water gets behind the roof covering.
Flashing problems often hide inside the wall rather than on the ceiling. 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. That is why flashing deserves a close look on any house with walls rising above a roof.
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. Lasting flashing repair means new metal installed in the right order, with sealant only as a backup.
Many flashing repair calls in Rahway also turn up a need for chimney flashing repair or roof leak repair.

The flashing repair process
Here is how a roofer typically approaches a flashing repair.
Check the flashing
Each joint is examined for missing kickouts, loose step pieces and counter flashing that no longer covers the top. Probing the wall below shows whether water has reached the sheathing.
Remove siding
To replace step flashing properly, a few courses of siding and the shingles along the wall are carefully removed. Working the new pieces in correctly depends on access behind the siding.
Replace the pieces
New step flashing is installed one piece per shingle course, each lapping the one below, with a kickout diverter at the bottom. Nails stay on the horizontal leg, high enough to be covered by the next shingle.
Add counter flashing
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.
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.
What is included
What flashing repair covers
Step flashing
Step pieces along walls and dormer cheeks are replaced behind the housewrap.
Drip edge
Edge metal is renewed along the roof perimeter to protect the deck edge.
Headwall flashing
Apron flashing where a roof slope meets a wall above is renewed so water cannot run behind it.
Kickout flashing
A kickout is added where a roof edge ends against a wall so runoff stops soaking the siding.

Roof Flashing Repair Rahway, NJ
Roof flashing repair ranges from resetting a single loose piece to rebuilding a full sidewall. Minor work includes refastening loose metal or adding a missing kickout; bigger jobs mean pulling siding and replacing every step piece along a wall. The roofer should explain which applies before work begins.
Not every flashing metal works in every spot. Copper outlasts most roofs, galvanized steel is durable and aluminum is light and easy to bend, though it corrodes in contact with wet masonry. Dissimilar metals touching each other corrode, so repairs should match existing flashing or be separated.

Roof Valley Flashing Rahway, 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. Either way, a self-adhered membrane should line the valley under everything else.
Leaves and needles that pile up in a valley hold water and wear the shingles or rust the metal. Small installation details, like clipping the upper corners of the cut shingles, keep water flowing down the valley instead of across it. Fixing a valley usually involves stripping it, relining it and installing new metal or reshingling.

In Rahway, many flashing problems date back to an old reroof where the original flashing was reused or caulked instead of replaced. From Rahway out to neighboring towns such as Avenel, Colonia, Linden and Iselin, older homes often have rusted or face-nailed flashing, while newer ones sometimes lack kickouts entirely, which is why roofers pay extra attention to walls, dormers and additions.

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

Common questions about flashing repair
Is it possible to fix flashing without a new roof?
Flashing is repaired on existing roofs all the time. Only the shingles and siding next to the joint come off while new metal goes in. For a worn-out roof, combining the work with a replacement avoids doing the joint twice.
Can I just seal the flashing with caulk?
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. The lasting fix is new flashing installed and lapped correctly.
What are the signs of bad roof flashing?
Look for stains or drips that line up with a roof-to-wall joint. From outside, rusted, loose or caulked-over flashing is a warning sign. Stained trim where a roof edge meets a wall is a common clue too. Call (908) 562-6861 to have a roofer check it.
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.
Why does my roof need kickout flashing?
It is a bent piece of flashing at the lower end of a sidewall joint. 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.
