Clogged Gutter Causing Roof Leak or Overflow — Causes, Fixes & Cost in KL
Water overflows from gutter during rain, causing wall or ceiling leaks.
Estimated professional fix: RM280–RM1,200+ depending on cleaning + repair scope
Gutters overflow in Malaysian downpours when leaves and debris block the channel or the downpipe, and sagging sections let water pool instead of draining. The overflow then runs down fascia and walls, and can find its way into the ceiling.
