Tile Roof Valley Leak Repair Done Right

A small leak is rarely just a small leak. What looks like a minor drip inside can trace back to a valley that's been quietly failing for a while - debris packs in, water backs up, and the underlayment underneath starts breaking down. That's exactly what we found on this tile roof.

The valley was the culprit. Years of buildup had worn through the underlayment, and water was finding its way in. We pulled the tiles from the affected area, stripped out the damaged underlayment, and got a clear look at what we were actually dealing with. The deck and valley metal both needed attention before anything else went back on.

Fresh underlayment went down first - clean, flat, no shortcuts. Then we reinstalled the valley metal and carefully reset the tiles. The whole point of doing it in this order is so every layer is doing its job. Skip a step and you're just covering up the problem instead of fixing it.

This kind of roof repair is about more than stopping water today. It's about making sure the repair holds. Tile roofs are built to last, but only when the system underneath them is sound. Underlayment is what stands between the tiles and your home, and it doesn't announce when it's failing - that's why ignoring even a small leak is a gamble.

If you've noticed a water stain on the ceiling or tracked down a drip after a storm, don't let it sit. The longer a roof leak repair gets put off, the more the damage spreads - and the more expensive it gets. We've seen it enough times to know: catching it early makes all the difference.
