Flashing Repair Short Hills, NJ
Most leaks at walls, dormers and roof edges in Short Hills 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. Call (862) 424-5211 to reach a local roofer.
Shingles handle the open field of a roof; flashing handles the joints. Along a sidewall, individual step flashing pieces interleave with every course of shingles, counter flashing covers their tops, and a kickout diverter at the lower end turns water away from the siding. 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. At the base of a roof-to-wall joint, water with nowhere to go runs behind siding and soaks the wall framing. By the time it is visible, the repair may include some siding and wall sheathing too.
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. Proper flashing sheds water by gravity and lapping, so it keeps working even after any sealant ages.
Flashing Repair is often paired with chimney flashing repair and roof leak repair, depending on the cause.

Call nowThe process
What happens during a flashing repair
Flashing repair is a layering job, done from the bottom up.
Check the flashing
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.
Open the joint
The shingles next to the wall come up, and the lowest siding courses come off to expose the flashing. New flashing has to tuck behind the housewrap, which means opening the wall a little.
Install new flashing
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. 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. The lap order differs at eaves and rakes, and getting it right matters.
What is included
Flashing a roofer can repair
Cap flashing
Counter flashing over step pieces is refitted or replaced without relying on caulk alone.
Edge flashing
Drip edge is added where it was left off 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.
Step flashing
Step pieces along walls and dormer cheeks are replaced behind the housewrap.

Roof Flashing Repair Short Hills, NJ
The scope of a flashing repair depends on the joint and on how much damage the water has done. 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.
Material matters too. 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 Short Hills, 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. 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. 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.

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, 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 Short Hills is busiest after a hard winter and before the next one.

Flashing Repair questions
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. Missing kickouts are a common cause of hidden wall rot.
Can flashing be repaired without replacing the 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. 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?
Water showing up near a wall joint, skylight or valley points to flashing. Outside, look for rust, gaps, lifted metal, nails through the face and heavy caulk along the joint. Rot at the base of a sidewall suggests water is getting behind the siding. A roofer reached at (862) 424-5211 can look at every joint.
Can I just seal the flashing with caulk?
Caulk can slow a flashing leak but almost never fixes it. It shrinks and pulls away, then lets water in where nobody can see it. A proper repair replaces the metal so it sheds water without depending on sealant.
What is step flashing and why does it matter?
Step flashing is a series of small L-shaped pieces, one for each course of shingles along a wall. Because each piece laps the one below, water is passed down the wall joint from piece to piece and onto the roof. One continuous piece along a sloped wall lets water run under the shingles instead.
