Performance Standard: Chimney flashing shall not leak.
Corrective Measure: The remodeler will repair leaks in chimney flashing.
Discussion: Chimney flashing leaks can be prevented. Possible causes include:
- Failure to install a small valley behind the chimney to divert water around the chimney, or
- Depending on tar to seal the flashing to the chimney instead of building the flashing into the chimney mortar joints.
