Technical Guide
What Katy Property Owners Need to Know
Chimneys penetrate both the roof deck and the exterior weather envelope, requiring an intricate multi-layer flashing system. Step flashing along the roof slope and counter-flashing cut into masonry joints must expand and contract independently; when caulking dries or step metal rusts, leaks immediately enter fireplace walls and living room ceilings.
Common Failure Triggers
Primary Causes of Chimney Flashing Repair in Katy
Understanding what causes this component to fail in our local subtropical climate:
Rusted or Missing Step Flashing
Individual metal step tins between shingle courses corrode or were improperly nailed during initial installation.
Backpan & Cricket Failure
Chimneys wider than 30 inches without a properly flashed cricket pool water on the uphill side, rotting decking.
Masonry Brick Porosity
Unsealed brick mortar absorbs driving rain, allowing water to bypass flashings entirely and drip into attics.
