Diverter flashing
Missing kickout diverters are installed at the base of sidewalls which protects the wall below.
Most leaks at walls, dormers and roof edges in Rutherford 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. Dial (551) 380-1579 to talk with a local roofer about the flashing.
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. Each of those pieces has one job, and when it fails, water finds the gap.
A failed kickout or step flashing tends to rot wall sheathing long before it stains a 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. Catching it early keeps the repair to the flashing instead of the wall.
A bead of sealant along a joint is a warning sign, not a repair. Roofing cement and caulk shrink, crack and pull away under sun and temperature swings, then let water in again. A real repair replaces the metal, often by removing a few courses of siding and shingles so the new flashing can be lapped correctly.
Many flashing repair calls in Rutherford also turn up a need for chimney flashing repair or roof leak repair.

Call nowFlashing repair is a layering job, done from the bottom up.
The flashing is checked along its full length, from the eave up, along with the wall sheathing where it can be seen. Probing the wall below shows whether water has reached the sheathing.
To replace step flashing properly, a few courses of siding and the shingles along the wall are carefully removed. New flashing has to tuck behind the housewrap, which means opening the wall a little.
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.
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.
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.

The flashing across the top of a roof section is redone so water cannot run behind it.
Bent or missing drip edge is replaced at eaves and rakes so water drips clear of the fascia.
Cap flashing on masonry is reset into the mortar joint so the top edge of the step flashing stays covered.
Loose or rusted step flashing is renewed and woven with new shingles.
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. Ask the roofer which kind of repair your joint needs.
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.
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.
Valley leaks often come from debris, worn shingles or nails driven too close to the center. Uncut shingle corners can catch water and direct it under the roofing. A valley that leaks is generally rebuilt rather than patched.
Flashing repairs in Rutherford are common on houses with dormers, additions and second-story walls rising above lower roofs. Across Rutherford and nearby communities including East Rutherford, Wallington, Carlstadt and North Arlington, the age of the house and the number of roof-to-wall joints decide how much flashing work is likely, and each of those joints is a place worth checking.

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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. That is why roof repair in Rutherford 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 Rutherford know the roof types and weather wear common in local homes.
Ask the roofer about the cause, the options and the estimate before work starts.
