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.
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.

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.
