A common cause of a leaky roof can begin with the valleys. Old rusty valley irons will start to leak as they rust out.
There could also be the common problem of an over bedded valley. Usually, the best option is to replace the whole valley with new zinc or colorbond one. Then depending on the owner's request, the valley can then be left dry (no cement work) with the option of adding a tar-based material called valley seal.
An old valley iron. As can be seen, it was starting to rust and the cement work was falling out causing the valley to leak.
We begin the valley replacement process by removing all the tiles.
We now remove all the old cement work from the valley.
Next up we remove and dispose of the old valley iron.
The new Colorbond valley iron is installed. When installing it is important to put a weather fold on the top and bottom of the valley iron.

The valley tiles are re-installed. Any tiles that are broken or short are re-cut as required.
We install the valley seal under the tiles. The valley seal will help to form a barrier against water, insects, birds and leaves.
The valley replacement is now complete. The ridge above are bedded and pointed and the roof is ready for paint.
