Roof Flashing Repair for Mechanicsburg homes

Flashing is the metal that seals the joints where a roof meets something else: a chimney, a wall, a skylight, a valley, or a vent. These transitions are where water most often finds a way in.

Flashing can rust, loosen, lose its sealant, or be installed incorrectly from the start. A proper repair often means lifting nearby shingles and rebuilding the detail rather than just adding caulk.

Signs of flashing trouble

  • Water stains near a chimney on the ceiling or in the attic
  • Rust streaks or gaps along chimney metal
  • Dried, cracked sealant where metal meets brick or siding
  • Leaks along a wall where a lower roof meets a second story
  • Drips around a skylight frame during wind driven rain

The process

How roof flashing repair works, step by step

  1. 1

    Confirm the source

    It is worth confirming the flashing is really the cause before taking anything apart.

  2. 2

    Open the detail

    Shingles around the area are lifted to expose the old flashing.

  3. 3

    Rebuild in layers

    New flashing is installed so each piece directs water over the next.

  4. 4

    Close and seal

    Shingles are reset and counter flashing or sealing completes the detail.

Why caulk alone is not a repair

Sealant can buy time, but it breaks down under sun and temperature swings. Properly layered metal flashing keeps working because it relies on gravity and overlap rather than adhesive.

On brick chimneys, counter flashing is commonly set into the mortar joints. That detail is often the difference between a tight chimney and a seasonal leak.

Common questions

Can flashing be repaired without a new roof?

Usually, yes, as long as the surrounding shingles are in reasonable condition.

What is kickout flashing?

A small angled piece at the bottom of a roof to wall joint that steers water into the gutter instead of behind the siding.
