Chimney & Flashing Repair in Juneau, Alaska

Chimney & Flashing Repair in Juneau, Alaska

The chimney is a roof penetration that moves differently than the rest of the roof. The chimney settles, the roof shifts, and the flashing that seals the gap loosens. In the City and Borough of Juneau, the constant rain finds that loosened gap fast. Chimney and flashing repair in Juneau means re-sealing the joint that keeps the rain out.

Signs Your Juneau Chimney Flashing Is Leaking

• Water stains on the ceiling near the chimney — the classic sign
• Damp insulation in the attic near the chimney — the rain is dripping onto it
• White deposits on the chimney — mineral residue from water that evaporated
• Visible gaps in the flashing — the step flashing has pulled away from the chimney
• Rust or corrosion on the flashing — the metal is failing

Why Chimney Flashing Fails in Juneau

The chimney sits on its own foundation, and the roof sits on the house foundation. In the borough’s wet climate, the two foundations move differently, and the gap between them opens and closes. The step flashing, which seals that gap, works loose over time.

The constant rain makes it worse. The moisture runs down the chimney and finds the loosened flashing, and the water goes straight through into the attic.

The repair is a careful job. The step flashing has to be integrated into the chimney’s counter flashing, which is set into the masonry. A sealant-only fix doesn’t last in the rainforest.

Preventing Chimney Flashing Problems in Juneau

• Check the flashing each spring — catch a loose seal before the heaviest rain
• Clear debris from the chimney base — reduce the moisture against the flashing
• Watch for white deposits — the first sign of a water path
• Keep the chimney cap in good shape — a cap diverts water from the flashing

Chimney note: the flashing is the chimney’s only defense against water entry. If the chimney is leaking, the flashing is the cause, and a sealant-only fix won’t last in the borough.
