Flashing & Vent Repair in Northridge, CA

Quick answer

Renewal of the metal details where Northridge roofs let water in: chimneys, walls, valleys, and vent stacks.

Flashing repair is where Northridge roofs actually leak: chimney saddles from the earthquake era housing stock, wall and valley flashing, and vent boots that the Valley sun embrittles years before the field of the roof fails. Renewal replaces the metal and seals the joint in materials chosen for a sun exposure inland counties never test, and it is priced as the detail work it is.

Signs you need flashing & vent repair

A leak that tracks to a chimney, skylight, or wall junction
Rubber vent boots cracked or split around plumbing pipes
Rust streaks or open joints at a valley
Caulk smeared over a joint by a prior repair, now split again
Water entering at the same corner after every hard rain

What the job involves

1. The joint is opened and read: flashing fails by corrosion, by movement, and by being installed as one flat piece where step flashing belonged.

2. Failed metal is replaced in kind and in sequence: step flashing woven with each shingle course, counter flashing cut into mortar or siding as the wall requires.

3. Vent boots are replaced, not sealed; the rubber collar is a wear part with a known life shorter than the shingles around it.

4. The finished detail is checked against wind driven rain direction, which is the rain that finds flashing.

5. Interior stains below the detail are checked for drying needs before the file closes.

What affects the price

Which detail failed and how many penetrations share its age
Wall material the counter flashing must meet (brick, stucco, siding, stone)
How much roofing must be lifted to do the detail as a system
Whether chimney masonry itself needs a mason alongside

When it is an emergency

A flashing leak is a this week call that becomes a today call when drywall starts going soft. Do not let anyone sell you a tube of sealant as a flashing repair: sealant is a dressing, and the joint underneath keeps moving. The cheap correct fix is the part replaced once.
