More than half of Winter Park homes predate 1980, so many chimneys are brick with crowns and flashing that have been through several roofs and decades of summer storms. It explains most of the leak calls.
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 chimney crown work and replacing the 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 roof-line flashing repair.
Each needs a different repair, which is why the entry point comes first. On the top alone, how caps and chase covers differ decides which part is at fault.
Water entry, Winter Park style
Summer storms bring the heaviest, most wind-driven rain of the year, and that is what exposes small crown cracks, open mortar joints and flashing that was only caulked at the last reroof. The leak point on the chimney is often not directly above the stain inside.
Reading where the water shows up
| Where you see water | Often points to | Checked first |
|---|---|---|
| Ceiling or wall beside the chimney | Water at the roof line | Flashing and any cricket |
| Inside the firebox or on the damper | Water coming down the flue | Cap, crown or storm collar |
| High on the chimney breast | Water through the brick or crown | Crown and mortar joints |
| Rust streaks down a chase | Water pooling on the chase top | Chase cover |
Water can travel before it shows, so this is a starting point; see how to read stains beside a chimney.
Leak or condensation?
Not all water in a chimney is rain. A flue that is oversized or poorly insulated for a gas appliance can condense moisture from exhaust, leaving stains that appear with no rain at all. That is fixed with liner work, not flashing or a crown.
If stains line up with rain, it’s a leak; if they don’t, the flue is checked instead. the common causes of water in a fireplace explains how to tell.
If the repair changes the exterior
If the house is designated or in one of the city’s historic districts, ask the City of Winter Park’s historic preservation staff before crown, cap or brick work begins.
