The storm has passed. Here is a safe, ordered way to check the house, from the roof line to the drains.
After a big storm, check the house in a set order: make it safe first, then walk round the outside looking at the roof, gutters, trees, awnings and gates from the ground, then go inside to check ceilings, windows, power and electronics, and finally the drains. Record what you find before anything is moved, for insurance. Small fixes are often modest: ClickBina's roof leak guide puts clearing valleys, gutters and downpipes at RM150 – RM500 (indicative 2026, Klang Valley).
Work from the outside in, and from the top down. The table is a checklist you can follow on your phone.
| Area | What to look for | Next step |
|---|---|---|
| Roof, from the ground | Slipped or missing tiles, lifted metal sheets, bent flashing | Arrange a roof check; do not climb |
| Gutters and downpipes | Overflowing, sagging, full of leaves, detached brackets | Clear and re-fix |
| Trees and branches | Cracked limbs, leaning trunk, lifted roots, branches on the roof | Prune or remove; TNB if near wires |
| Awning, car porch, gate, fence | Loose sheets, twisted frames, gate off its track | Secure loose parts; get them checked |
| Aircon outdoor units | Debris in the fins, bracket movement, water around the unit | Clear debris; test before running for long |
| Ceilings and walls inside | New stains, sagging ceiling boards, damp patches | Trace the leak before repainting |
| Windows and doors | Water on sills, wet curtains, leaks at frames | Check seals and drainage slots |
| Power and electronics | Tripped breakers, dead sockets, devices not working | Reset once; if it trips again, call an electrician |
| Drains and floor traps | Slow drains, debris, sewage rising | Clear debris; check the inspection chamber |
Most storm leaks come from three places: overflowing gutters and valleys, slipped or cracked tiles, and flashing that has lifted at walls and edges. ClickBina's roof leak in heavy rain guide explains why a roof may only leak in heavy rain and why a stain can appear metres from the actual entry point. Look along the roof from the street, and from an upstairs window if you can see across it.
Wind-driven rain is the other storm culprit: water blown sideways under tiles that keep ordinary rain out. Our wind-driven rain guide covers the sarking and underlay fix. If the storm season is still running, the monsoon roof checklist sets out what to fix before the next one.
Storms find the weak points in trees: cracked unions where two main stems join, dead branches, and roots loosened in saturated soil. A tree that has started to lean after a storm, or has lifted the ground at its base, needs assessing before the next one. Branches lying on the roof can crack tiles and block gutters, so have them removed rather than left to slide off.
Inside, look up. New brown stains, bubbling paint and sagging ceiling boards all point to water above. A plasterboard ceiling that is sagging and heavy with water should be kept clear underneath, because it can come down. Check window sills, the bottom of sliding door tracks and curtains on the windward side; water that got in only during the storm often points to blocked drainage slots or failed seals rather than broken glass.
Do not repaint a stain straight away. Let it dry and watch whether it returns in the next rain, which tells you whether the leak is still active. If the source is hidden, ClickBina's leak detection is a separate paid visit at RM300 – RM800.
Lightning nearby can send a surge through power, phone and data cables. A breaker that trips once and resets may be nothing; one that trips again, a burning smell, or sockets that stay dead need an electrician. For CCTV, ClickBina's CCTV lightning and surge guide gives a clear after-storm routine: check every channel on the recorder, not just the app, confirm it is still recording, play back the storm period, and check the router, because it sits on the same paths and fails quietly. Write down the date; a part that fails weeks later may still be storm damage.
Clear leaves and debris from aircon outdoor units, and check that brackets have not moved. If a unit was sitting in water or will not cool properly after the storm, ClickBina's aircon diagnostic is RM120 – RM400. Look at awnings and car porch roofs for lifted sheets and loose fixings, and at auto-gates for a motor that stalls or a gate that has come off its track. Loose sheets can become flying debris in the next storm, so secure or remove them.
Storms wash leaves, silt and sand into drains and floor traps. Clear the grating over outside drains and check that water runs away freely. If sewage rose in a ground-floor toilet or floor trap during the storm, that is a sign the sewer line was full; our guide to sewage backing up in heavy rain explains how to check the inspection chamber and what fixes it.
Before moving or repairing anything, record the damage: what, where, and when you found it, with notes of the date and time of the storm. Keep damaged items until the insurer has seen them or said you can discard them. ClickBina's guide to fire insurance and water damage perils explains which kinds of storm and water damage a home policy may or may not cover.
These are ranges from ClickBina's guides (indicative 2026, Klang Valley). Larger damage, such as a roof section torn off or a fallen tree through a structure, is quoted after a look.
| Repair | Indicative price | Notes |
|---|---|---|
| Clear valleys, gutters and downpipes | RM150 – RM500 | Often solves leaks that are really overflows |
| Replace cracked or slipped tiles | RM300 – RM1,000 | Access and tile matching drive the price |
| Repair or renew flashing | RM500 – RM2,000 | A common heavy-rain culprit on tiled roofs |
| Aircon diagnostic | RM120 – RM400 | Unit not cooling or tripping after the storm |
| Leak detection (ClickBina) | RM300 – RM800 | Separate paid visit |
