Early warning signs of a failing roof

A roof usually gives you plenty of notice before it lets the rain in. The trick is knowing what to look for — ideally before the wet season.

By the time water drips onto your floor, it has often been getting in for weeks. These five clues let you act while a repair is still small.

1. Faint ceiling stains

A yellow-brown halo on the ceiling or cornice is the classic first sign. It may dry out between rains, which fools people into ignoring it — but the water path is already there and will only widen.

2. Slipped or cracked tiles

Take a look from the ground with binoculars after a windy day. Tiles that have shifted out of line, cracked or gone porous are open invitations for water to get beneath them.

3. Blocked or overflowing gutters

When gutters clog with leaves and silt, rain backs up under the roof edge instead of draining away. Overflow marks down your exterior wall are a quiet warning worth heeding.

4. Peeling paint or bubbling plaster

Moisture trapped in the ceiling or upper walls lifts paint and bubbles plaster long before it drips. If a patch of your upstairs ceiling looks blistered, water is likely behind it.

5. A musty smell upstairs

Persistent damp has a smell. If a room under the roof develops a mustiness that airing doesn’t clear, there may be moisture sitting in the roof space feeding mould.

Don’t wait for the drip

Caught early, most roof issues are a targeted repair or a re-coat. Left until the ceiling sags, they become a much bigger job. If any of these signs sound familiar, send us a photo and we’ll take a look.
