Flashing Repair Randolph, NJ
Most leaks at walls, dormers and roof edges in Randolph come down to flashing, and a roofer can fix it by replacing the failed metal rather than caulking over it, with the wall sheathing checked for hidden rot. One call to (973) 858-1826 reaches a nearby roofer who repairs flashing.
Shingles handle the open field of a roof; flashing handles the joints. 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. A single missing or loose piece is enough to send water behind the shingles or into the wall.
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.
Caulk is not flashing. Sealant smeared where flashing should be dries and cracks in a few seasons, and it can trap water instead of shedding it. Lasting flashing repair means new metal installed in the right order, with sealant only as a backup.
If the problem goes deeper than it first looked, a Randolph roofer may also recommend chimney flashing repair or roof leak repair.

Call nowThe process
What happens during a flashing repair
Flashing repair is a layering job, done from the bottom up.
Find the failure
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
To replace step flashing properly, a few courses of siding and the shingles along the wall are carefully removed. That is the only way to lap new metal behind the wall weather barrier.
Weave in the metal
Fresh step flashing goes in course by course with the shingles, starting with a kickout at the eave. Fasteners go into the roof deck only, never through the vertical leg into the wall.
Add counter flashing
Housewrap is lapped over the vertical legs, then siding goes back on with a gap above the shingles so it does not wick water. 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. Correct laps at the edges keep water out of the fascia and soffit.
What is included
Flashing a roofer can repair
Sidewall flashing
Step pieces along walls and dormer cheeks are replaced behind the housewrap.
Edge flashing
Bent or missing drip edge is replaced at eaves and rakes so water drips clear of the fascia.
Counter flashing
Counter flashing over step pieces is refitted or replaced so the top edge of the step flashing stays covered.
Apron flashing
Headwall metal at the top of a slope is replaced so water cannot run behind it.

Roof Flashing Repair Randolph, 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.
The metal used should suit the house. Copper, galvanized steel and aluminum all show up on roofs, and each has spots where it works best. Matching metals avoids corrosion where new and old flashing meet.

Roof Valley Flashing Randolph, NJ
A valley is where two roof slopes meet, and it channels a large share of the roof water toward the eave. 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.
Leaves and needles that pile up in a valley hold water and wear the shingles or rust the metal. Uncut shingle corners can catch water and direct it under the roofing. 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
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, 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. Most homeowners in Randolph, NJ have the roof checked in the fall and again after the snow melts.

Flashing Repair FAQ
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. The overlap carries water down the wall joint and out onto the shingle surface. A long single strip sends water under the roofing, which is why step pieces are the standard.
Is it possible to fix flashing without a new roof?
Most flashing problems are fixed without touching the rest of the roof. 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.
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. Stained trim where a roof edge meets a wall is a common clue too. Call (973) 858-1826 to have a roofer check it.
Will caulk fix leaking flashing?
Caulk can slow a flashing leak but almost never fixes it. 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.
Why does my roof need kickout flashing?
Kickout flashing sits where a roof eave dies into a sidewall. It turns water that runs down the step flashing outward into the gutter instead of letting it pour behind the siding. Leaving it out is one of the most common causes of rot in the wall under a roof edge.
