In Oviedo’s 1990s homes, the original galvanized chase cover is often the first part of the chimney to fail, and the long wet season is when it shows. Here’s what that means for leaks.
Top, sides or roof line
Chimney leaks come from three places. The top: a cracked crown, a missing cap or a rusted chase cover lets rain fall straight in; see a rebuilt crown and a new chase cover. The sides: brick and open mortar joints soak up wind-driven rain, and on a chase, siding seams let water behind. The roof line: step and counter-flashing that were cut short, left loose or only caulked; see step and counter-flashing repair.
Each needs a different repair, which is why the entry point comes first. On the top alone, caps versus chase covers decides which part is at fault.
Why Oviedo chimneys let water in
In a factory-built fireplace, water in the firebox usually runs down the flue from the top: a failed storm collar, a damaged termination cap or a rusted chase cover.
How the entry point is found
Map the symptom
Where the water shows up, after what kind of rain, and how long after it starts.
Check inside first
Firebox, damper and, where accessible, the attic around the chimney.
Check the top and the roof line
Crown, cap or chase cover, storm collar, flashing and the masonry or siding.
Isolate if needed
Water is run on suspect areas one at a time to confirm which one leaks.
Repair that point
Then watch the next heavy rain to confirm it’s dry.
Leaks that start after a reroof
Many chimney leaks begin the season after a new roof. If the old flashing was reused, cut short or only caulked instead of being properly set into the chimney, the first wind-driven storm finds it.
Some flashing leaks are roofing work and some are chimney work, so tracing tells you which trade you need. See reroofing and chimney flashing and how flashing leaks show up.
Water now, damage later
A leak left for years turns into masonry damage: eroded joints, spalling brick, rusted dampers and rotted chase framing. Once that has happened, the job includes repair for damaged masonry as well as stopping the water, and the yearly inspection shows how far it has gone.
