Do I have a leak?
If there are brown stains on the ceiling you definitely have a leak. Whether this is caused by a leaky roof or a geyser overflow pipe, you will need to find the source of the problem as soon as possible.
Mould on the ceiling is not always an indication of a leaky roof. Ceiling mould can also be caused by damp, especially in a bathroom or laundry room. However, it is better to be safe and take a look in the attic or roof space.

Into the attic or roof
Use the access panel to get into the attic or roof space to inspect from underneath. Look for areas where sunlight is coming through tiles to locate a slipped or broken tile.
Major leaks caused by multiple broken tiles, loose ridge caps or corroded flashings are best left to the professionals.

Most minor roof leaks are caused by a loose/
slipped tile which is fairly easy to repair.
Shift a tile back into position using a piece of stiff wire with a self-made hook at the end. Use the hook to pull the tile back along the laths (timber cross beams that support the tiles).
If more than one tile has slipped, use wooden battens to lift
the two overlapping tiles immediately above the tile or tiles you need
to move.

Replacing a cracked or broken tile
Use wooden battens to lift the two overlapping tiles above the broken tile. Try to pull out the damaged tile through the gap created. You may need to wiggle from side to side if the tile has been nailed into position. As a final resort, wear gloves and goggles and break the tile to remove it.
Position the new tile by manoeuvering it into place and making sure that it is bedded on the support laths.

Slipped, cracked or broken ridge cap
This job requires that you get onto the roof to replace and cement a new ridge cap in place. If in any doubt, call in the professionals.

Leaks around skylights and domes
Annual inspection of the condition of skylights and domes to correct any corrosion or wear and tear will ensure that these fittings do not leak in the future. Where you suspect a leak in this region, apply a waterproofing product and membrane around the fitting.
