Chimney flashing

The metal flashing that seals where a chimney passes through the roof.

On a real claim

Chimney flashing is the metal that seals the roof where it meets the chimney, including step flashing, counter flashing, and a cricket on wide chimneys. On a claim it is a frequent source of hidden leaks and a common supplement because it is fiddly and easy to leave off a first estimate. What goes wrong: a crew re-roofs up to the chimney and reuses old, pitted flashing, and the leak comes back. Check the flashing condition and price the full rebuild rather than a patch.
