Flashing Repair Mahwah, NJ
A roofer in Mahwah can repair or replace the step flashing, counter flashing, kickout flashing, valley metal and drip edge that seal the joints of a roof, with the wall sheathing checked for hidden rot. Dial (551) 351-0251 to talk with a local roofer about the flashing.
Flashing is the thin metal that seals every place the roof surface is interrupted. 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. When any piece is missing, loose or rusted through, water gets behind the roof covering.
A failed kickout or step flashing tends to rot wall sheathing long before it stains a ceiling. Without a kickout, roof runoff dumps against the siding where the wall meets the eave, soaking the sheathing and framing below it. That is why flashing deserves a close look on any house with walls rising above a roof.
Caulk is not flashing. Sealant can hold for a while, but it fails sooner or later, and the joint leaks once more. Proper flashing sheds water by gravity and lapping, so it keeps working even after any sealant ages.
Depending on what the roofer finds, flashing repair in Mahwah, NJ can go hand in hand with chimney flashing repair and roof leak repair.

Call nowThe process
What happens during a flashing repair
Good flashing work is mostly about the order things overlap.
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. Probing the wall below shows whether water has reached the sheathing.
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.
Install new flashing
Fresh step flashing goes in course by course with the shingles, starting with a kickout at the eave. Nails stay on the horizontal leg, high enough to be covered by the next shingle.
Seal the wall side
Housewrap is lapped over the vertical legs, then siding goes back on with a gap above the shingles so it does not wick water. The gap lets the joint dry and keeps trim from wicking water.
Seal the eaves
Damaged drip edge is renewed so water drips clear of the fascia. Correct laps at the edges keep water out of the fascia and soffit.
What is included
Flashing a roofer can repair
Cap flashing
Loose counter flashing is secured without relying on caulk alone.
Apron flashing
Apron flashing where a roof slope meets a wall above is renewed with proper laps over the shingles.
Sidewall flashing
Loose or rusted step flashing is renewed and woven with new shingles.
Diverter flashing
Kickouts are fitted at the bottom of roof-to-wall joints so runoff stops soaking the siding.

Roof Flashing Repair Mahwah, 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.
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 Mahwah, 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. Both need ice and water shield underneath, centered in the valley.
Common valley problems include rusted metal, debris dams, worn shingles and nails placed too close to the centerline. 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.

What the local climate does to a roof
Cold winters bring snow, ice and a long stretch of freezing nights. 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. Most homeowners in Mahwah, NJ have the roof checked in the fall and again after the snow melts.

Flashing Repair FAQ
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. The overlap carries water down the wall joint and out onto the shingle surface. A single long strip of metal along a wall cannot do that and tends to channel water behind the shingles.
Will caulk fix leaking flashing?
A bead of caulk may hold for a season or two, but it will fail. 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.
Is it possible to fix flashing without a new roof?
Most flashing problems are fixed without touching the rest of the roof. 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.
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. Missing kickouts are a common cause of hidden wall rot.
How do I know if my flashing is leaking?
Water showing up near a wall joint, skylight or valley points to flashing. Outside, check for metal that has pulled away, rust holes and old sealant patches. Rot at the base of a sidewall suggests water is getting behind the siding. A roofer reached at (551) 351-0251 can look at every joint.
