Chimney Flashing —

is a layered system of metal and waterproofing that seals where a brick chimney meets the roof.

When chimney flashing is missing or installed improperly, water can travel behind the metal and cause recurring leaks around the chimney.

QUICK ANSWERS

  • Damaged, cracked metal flashing around a brick chimney on an asphalt shingle roof

Warning signs: Ceiling stains near the chimney, damp brick, deteriorated caulking, rusted flashing, or leaks that repeatedly return

​

Typical solution: Remove the shingles and old flashing, repair damaged decking, and install new membrane, step flashing, and custom counter flashing

Expected longevity: Life of the surrounding roof when properly installed

​

Pricing: Inspection required (dependent on chimney size, roof pitch, accessibility, and hidden wood damage)

Concerned About Your Chimney Flashing?

Schedule an evaluation to determine whether the flashing—or the surrounding shingles and roof decking—needs repair.
