Roof Valley Replacement: When Melbourne Valleys Need Replacing, What Materials Last Longest, and What the Process Involves
Roof valley replacement is one of the most common and most important repairs on a tiled roof. Valleys handle more water than any other part of your roof. Every time it rains, the water from two entire roof slopes converges into the valley and funnels down to the gutter. When a valley fails, the water goes into your ceiling instead. Replacing a valley is not a patch job. It involves lifting the surrounding tiles, removing the old valley iron, installing new flashing, and relaying the tiles with correct overlap and sealant. Done properly, a replaced valley lasts 25 to 40 years.
