How Flashing Fails — 5 Steps

The Flashing Failure Sequence on Augusta Road Ranch Chimneys

Flashing failure on post-war ranch chimneys is not random — it follows a predictable sequence. Understanding where the failure is in the sequence determines the correct scope of repair.

1

Caulk Shrinks

Original sealant at step flashing laps dries and pulls away from the masonry face — first gap opens

2

Counter-Flash Lifts

Mortar holding counter-flashing into the chimney joint softens; the metal lifts and gaps behind the step flashing

3

Water Tracks In

Rain runs behind the lifted counter-flashing, soaks the brick-to-shingle joint, and begins wetting the roof deck

4

Deck Saturates

Repeated wetting saturates the roof deck and rafter ends; staining or mold appears in the attic or at the ceiling

5

Interior Signs

Homeowner notices staining on living room ceiling or drywall — often mistaken for a roof leak rather than chimney flashing

Original Flashing vs. Correct Flashing — What the Repair Changes

Original Ranch-Era Flashing — Common Problems

  • One-piece base flashing without interwoven step flashing — creates a continuous gap under water pressure
  • Counter-flashing set in mortar joint without a cut reglet — mortar softens and the metal lifts out
  • Caulk-only sealing at lap joints — sealant has a 10–15 year service life; fails long before the brick
  • No saddle (cricket) behind a wide chimney — water pools behind the chimney on low-slope roof sections

Correct Repair Standard

  • Individual step flashing pieces woven with each shingle course — no continuous gap possible
  • Counter-flashing embedded in a cut reglet in the mortar joint and sealed with elastomeric sealant
  • No exposed caulk joints at the primary water barrier — mechanical lapping carries the water load
  • Saddle assessment for chimneys wider than 30 inches on Augusta Road low-slope roof sections
FAQ

Chimney Repair Questions — Augusta Road Greenville

Post-war ranch homes on Augusta Road were built with low-slope roofs and chimneys that penetrate at a shallow angle — geometry that puts continuous pressure on the flashing seal. After 60–80 years, step flashing has lifted, counter-flashing mortar has softened, and caulk joints have long since cracked. The result is a leak path at the chimney-to-roof joint that runs water into the attic or ceiling with every significant rain.
Step flashing is the L-shaped metal pieces that alternate with each shingle course up the side of the chimney, directing water onto the shingle below. Counter-flashing laps over the top of the step flashing and is embedded into the chimney mortar joints, preventing water from running behind the step flashing at the top. Both must be intact and properly lapped. The most common Augusta Road failure points are counter-flashing that has pulled from the mortar joint and step flashing that has lifted at the upper courses.
Flashing repair or replacement approximately $400–$1,100 depending on chimney perimeter and whether counter-flashing reglets need to be cut. Crown repair approximately $250–$700. Tuckpointing approximately $350–$850. Full scope and pricing confirmed on-site before work begins.
