Malaysia’s heavy rains find every weak point in a roof. A tile that’s been slightly out of place for a year suddenly lets water in; a gutter half full of leaves overflows back under the eaves. The faults were there all along — the monsoon just tests them. A short check beforehand keeps small problems small.
Clear the gutters and downpipes
Blocked gutters are the single most common cause of monsoon leaks. Water backs up, overflows and works its way under the roof edge and into the fascia. Clear out leaves and grit, and flush the downpipes to make sure they run freely.
Look for slipped or cracked tiles
From the ground with binoculars, or safely from a window, scan for tiles that have slipped, cracked or gone missing. Even one displaced tile is an open door for driving rain.
Check the flashing and ridge caps
Flashing seals the joins around chimneys, walls and valleys, and ridge caps sit along the peak. These are prime leak spots. Look for rust, gaps or cracked mortar bedding on the ridge line.
Inspect the ceiling from inside
Go into the roof space if you can, on a bright day. Daylight coming through where it shouldn’t, or dark water stains on the underside of the roof, tell you exactly where water has been getting in.
Consider a protective coating
If your roof is sound but ageing, a heat-reflective protective coating seals hairline cracks and adds years of life. It’s far cheaper than a re-roof and it keeps the house cooler too.
Know when to call in help
Roof work is high, awkward and easy to get wrong. If you spot damage, or you’d simply rather not climb up, a proper inspection is inexpensive and gives you a clear list of what — if anything — needs doing before the rains.
