An annual roof inspection can help you avoid costly roof repairs by identifying roof leaks early.
Most minor roof leaks are caused by a tile that has come loose or slipped, and this is fairly easy to repair.Here’s what to look for…
Does my roof 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’ll 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 as it can be caused by damp, especially if it’s in a bathroom or laundry room. To rule out roof leaks, take a look at the attic or roof space.
Inspect the attic or roof space
Use the access panel to get into the attic or roof space to inspect the roof above. Look for areas where sunlight is coming through the 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.
Replace a slipped tile
Replace cracked or broken tiles by positioning the new tile into place and making sure that it is bedded on the support laths.Most minor roof leaks are caused by a tile that has come loose or slipped, and this is fairly easy to repair.
A bad storm, especially with high winds, can sometimes cause a tile to slip out of place. This can be rectified by shifting the tile back into position.
Get a piece of stiff wire (or wire coat hanger) and bend it to create a hook at the end. Use the hook to pull the tile back into position 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.
Replace cracked or broken roof tiles
For a cracked or broken tile, use wooden battens to lift the two overlapping tiles above the cracked or broken tile.
Try to pull out the damaged tile through the gap. If the tile has been nailed into position, you may need to twist it out. If the tile is stuck in place, as a final resort, you may have to break the tile to remove it. Remember to wear gloves and goggles to protect your hands and eyes.
Age, bad weather and poor installation can often result in leaks around skylights, solar domes and other installed fittings that are attached to the roof.Position the new tile by manoeuvring it into place and making sure that it is bedded on the support laths.
Fix slipped, cracked or broken ridge cap
This job requires you to get onto the roof to replace and cement a new ridge cap. If in doubt, call the professionals.
Leaks around skylights and domes
Age, bad weather and poor installation can often result in leaks around skylights, solar domes and other installed fittings that are attached to the roof. Regular inspection can help identify leaks early.
Annually inspecting the condition of the skylights and domes to correct any corrosion or wear and tear will ensure that these fittings don’t leak in the future.
Where you suspect a leak in this region, apply a waterproofing product and membrane around the fitting.
