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?
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.
