Why Is My Tile Roof Leaking?

When a tile roof leaks in Florida, the most common cause is not the tiles themselves but rather the underlayment beneath them. In older tile roofs—typically those over 20–25 years old—the underlayment degrades and fails, allowing water to penetrate even when the tiles appear intact. Other common causes of tile roof leaks include broken or displaced tiles, failed flashing around penetrations, deteriorated pipe boots, and cracked or missing ridge cap mortar. Ranger Roofing diagnoses and repairs tile roof leaks throughout Palm Beach County.
Most Common Causes of Tile Roof Leaks in Florida
Failed Underlayment: The #1 cause of tile roof leaks in Florida homes over 20 years old. The underlayment beneath the tiles deteriorates and allows water to enter the home even when tiles appear undamaged.
Broken or Displaced Tiles: Cracked, broken, or wind-displaced tiles create direct pathways for rain to reach the underlayment and roof deck.
Failed Pipe Boot Seals: The rubber boots around plumbing vent pipes are exposed to UV and typically fail after 10-15 years, creating a common leak point.
Flashing Failures: Metal flashing around chimneys, skylights, and roof-to-wall transitions can corrode or separate from the structure, allowing water entry.
Ridge Cap Mortar Failure: The mortar holding ridge cap and hip cap tiles can crack and deteriorate over time, particularly after freeze-thaw cycles or from UV exposure.
