Diverter flashing
A kickout is added where a roof edge ends against a wall which protects the wall below.
A Montvale roofer can stop leaks where the roof meets a wall, dormer, skylight or edge by renewing the flashing at that joint, so water is shed by the metal itself. Dial (551) 390-0362 to talk with a local roofer about the flashing.
Flashing is the thin metal that seals every place the roof surface is interrupted. 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. By the time it is visible, the repair may include some siding and wall sheathing too.
A bead of sealant along a joint is a warning sign, not a repair. 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 Montvale also turn up a need for chimney flashing repair or roof leak repair.

Each joint is examined for missing kickouts, loose step pieces and counter flashing that no longer covers the top. Damage in the wall changes the scope, so it is checked early.
Siding is lifted or removed along the joint so the old flashing and housewrap can be reached. That is the only way to lap new metal behind the wall weather barrier.
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.
The weather barrier laps over the step flashing, and siding is reinstalled with clearance above the roof surface. Siding pressed tight to the shingles stays wet and rots.
At the roof edges, drip edge is reset or replaced to protect the fascia and deck edge. The lap order differs at eaves and rakes, and getting it right matters.
A kickout is added where a roof edge ends against a wall which protects the wall below.
The flashing across the top of a roof section is redone with proper laps over the shingles.
Cap flashing on masonry is reset into the mortar joint without relying on caulk alone.
Drip edge is added where it was left off so water drips clear of the fascia.
Sidewall flashing is rebuilt one course at a time so water stays on the roof.
The scope of a flashing repair depends on the joint and on how much damage the water has done. 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. Mixing copper with aluminum or galvanized metal in contact can cause corrosion, so the roofer matches the metal to what is already there.
Roof valleys carry the runoff from two slopes, so they handle more water than any other part of the roof. 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.
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. Valley repair usually means removing the shingles along the valley, replacing the membrane and metal and reshingling with the right cuts.
In Montvale, many flashing problems date back to an old reroof where the original flashing was reused or caulked instead of replaced. Homes in Montvale and nearby towns like Park Ridge, Woodcliff Lake, Saddle River and Hillsdale range from older houses with aging galvanized flashing and no kickouts to newer homes with complex rooflines that rely on many wall joints, so a close look at every joint is worth asking for.

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. That is why roof repair in Montvale is busiest after a hard winter and before the next one.
A roof problem fixed early rarely spreads to the decking, the insulation or the ceilings.
Roofers in Montvale know the roof types and weather wear common in local homes.
