Leaks at parapet — the most missed terrace detail

Water enters where parapet wall meets terrace slab — a detail often skipped by local waterproofers. In Guwahati high-rises, this causes chronic top-floor ceiling damage.

Symptoms

• Stains along top floor exterior wall
• Leak at ceiling-wall junction
• Cracks at parapet base
• Rust stains on exterior facade

Diagnosis

Visual and flood test focused on parapet upturn, coping, and counter-flashing details.

Do I need to rebuild parapet?

Rarely. Proper upturn membrane and coping repair usually fixes it.
