repair broken roof tile

If you don’t have any spares – can you repair a broken roof tile?

If you have a tiled roof – then sooner or later, you will have a broken roof tile. As a rule, tile roofers in Sydney leave behind spare roof tiles on every roof that they do. So, if this is the case, then you can simply change the roof tile.

But older roofs and even some of the newer roofs don’t have a stack of spare roof tiles stored in a corner. So, what happens if you get a cracked roof tile?

These types of silicone repair work are NOT 100% effective

In a pinch, a properly executed silicone repair can be effective as a temporary (or even permanent) solution to this problem. However, I have seen so many broken roof tiles repaired with silicone and still leak. This is because the roof repairer did not know the basics of how a roof tile function.

Most unsuccessful roof tile repairs are done without removal of the broken tile. This means that the visible crack is siliconed up but the all important drainage course that is hidden under the lap is left broken and un-sealed. This means that while the roof tile does not leak as bad – it still leaks.

It is critical that the full width of the roof tile is repaired – not just the exposed portion. If done correctly, the repair will be serviceable for a long time. It may not look great – but it is effective.

Hi how can you tell the difference between a tile that’s been broken from the inside rather then the outside? Why i ask is that my wife says that the tiles on the roof where broken from the inside not the outside, how can i know if this is true. Do you have pictures that you could show me the difference between standing on a tile and cracking it and a broken tile that’s been damaged from the inside. I’m finding this quite confusing, could you shine some light on this being a professional thanks toni.
