Flashing Repair

Flashing repair replaces the metal that joins a roof to a chimney, a wall, a valley, or a penetration. Most roof leaks that are not a worn-out shingle field start at that metal.

The work

What is flashing repair?

The failed piece is identified. Step flashing, counterflashing, valley metal, or a boot around a vent each fails in its own way. Smearing roof cement over the gap is not the repair. The metal is reset so water sheds onto the shingles below it.

Flashing that belongs to the chimney is also described on chimney flashing repair. A leak whose source is still unknown starts as roof leak repair.

Why it matters

Why this work matters

Flashings move and rust while the shingles around them still look acceptable. Replacing a whole roof to fix one joint is the wrong scope. Re-caulking a joint that has already opened is also the wrong scope.

The repair replaces the metal that failed and ties it back into the roof that is staying.
