Tile usually needs new underlayment, not new tile
Your tile will outlast the sheet beneath it, and that sheet is the underlayment. It keeps water off the decking, so trouble starts there, not in the tile. We lift the tile off in sections, then pull the failed underlayment out from underneath.
We repair whatever decking rotted under that sheet.
Our tile roofing page covers the relay in full.
How water leaves a San Marino roof
Rain leaves a roof through the valleys and the edge metal. We check both on every San Marino roof we quote. One slipped tile is a roof repair; leaks that keep opening in new spots point to a replacement instead.

How to tell if a roofer is lying?
Check the license number yourself on the state Check a License lookup. Then ask for a written scope naming underlayment, flashing, decking, and tile handling. Ask what the contractor will do about rot found under your tile, and get that in writing.
What is the 25% rule for roofing?
California code has no 25 percent rule for roofing. The real threshold applies in the High and Very High fire hazard severity zones on the state map. Replace half the covering there within twelve months, and that replacement must satisfy requirements for new construction.
What is the cheapest time of year to get a new roof?
Price follows the measurements we take on your roof, and the calendar month you call changes nothing. Roofing demand picks up around October and peaks from December through February. Dry weather still helps, because the deck sits open while we work in San Marino.
