Chimney and flashing leaks in Washburn

Flashing fails more often than shingles do, and the chimney is where it fails first. Masonry and roof framing move at different rates, which over years opens the joint where counter-flashing is set into the mortar. Step flashing up the sides, counter-flashing into the brick, and the cricket behind the stack are the usual suspects on a leak where the roof itself looks fine. On older chimneys the mortar joint holding the counter-flashing is often the actual failure rather than the metal.

What the job involves

  • Inspection of step flashing, counter-flashing, apron and cricket
  • Assessment of the mortar joint holding the counter-flashing
  • Removal and rebuild of failed flashing rather than sealant over the top

Signs you need it

  • Staining on the ceiling near the chimney breast
  • Damp on the chimney breast itself, inside the house
  • Rust streaks on the shingles below the stack

Why roofs fail in Washburn and Woodford County

Washburn gets the full range — freeze-thaw cycling through winter, severe convective storms with hail and straight-line wind in spring and summer, and enough temperature swing between them to work every joint on the roof loose. Freeze-thaw is the quiet one: water finds a hairline gap in flashing, freezes overnight, expands, and opens it slightly wider, repeating through a Woodford County winter until a joint that was watertight in October is leaking by March. Spring brings the loud damage, and derechos have put straight-line wind through this region at speeds that take ridge caps and whole shingle courses. Housing stock here is older than average, which means a lot of roofs where the flashing has already been through several decades of that cycle.

Washburn has a population of about 1,032, and the housing stock here sets the pattern for what fails first on a roof.

Questions about chimney and flashing leaks in Washburn

Can you just seal it rather than rebuild the flashing?

Sealant buys a season at most. It is applied over a joint that is moving, so it cracks at the first full temperature cycle. Where flashing has genuinely failed, rebuilding it is the repair; caulk is a way of paying twice.

Could the water be coming through the brickwork rather than the roof?

It can. A cracked crown, a missing cap, or spalled brick lets water into the stack and it shows up inside looking exactly like a flashing leak. Worth checking both — they are different trades and different fixes.
