Tile roofs are a striking choice for many buildings in Los Angeles and Phoenix. Their lines and profiles add character, and their mass often offers good coverage against extreme sun. But like any roofing material, tile comes with vulnerabilities. Understanding the problems that can arise and how they are addressed helps you guard against damage before small faults turn into major repair needs.

Cracked or Broken Tiles

Tiles may crack when objects fall on them, when someone walks on the roof carelessly, or when thermal stress causes expansion and contraction. A single broken piece might seem minor, but it often becomes a starting point for leaks. Fixing cracked tiles generally means removing the broken piece carefully and slipping a matching tile into place. The surrounding tiles must remain unshifted so you do not break adjacent units. For severe cracking across many tiles, you may need a partial re‑tiling of the affected area.

Issues with Underlayment or Waterproofing

Tile itself does not always provide full waterproofing. The underlayment beneath the tile (felt, membrane, or synthetic layers) plays a critical role. Over time, moisture, heat cycles, or improper installation can degrade that layer. When water infiltrates, you may see staining, mold, or wood rot on the decking below. Solving this kind of damage often means removing tiles, replacing or repairing the underlayment and flashing, and then restoring the tile surface. That work demands precision, because the seal must be tight under and around each tile.

Flashing Failures Around Penetrations

Roof penetrations, such as vents, chimneys, skylights, and plumbing stacks, are highly common spots for leaks. Flashing is the metal or membrane detail that bridges tile and structure transitions. If flashing is corroded, has gaps, or shifts over time, water will find a path in. Repair involves removing or adjusting adjacent tiles, resetting or replacing flashing, and sealing interfaces properly. The tile must be reinstalled in a way that restores the intended drainage path.

Sliding or Displaced Tiles

Tiles may slip from their original position due to gravity, wind uplift, or poor fastening. When a tile slides out, its neighbors may shift to fill the gap, compromising alignment and sealing. The roof begins to show uneven edges or visible cracks. Repairing this means repositioning the tiles carefully, adding clips or anchors where needed, and making sure adjacent tiles remain level and aligned. If tiles have shifted enough to damage mortar beds or locking features, those may need rebuilding.

Moss, Algae, and Surface Stains

Though less common in dry climates like Phoenix and Los Angeles, shaded or humid corners may still show moss, algae, or staining over time. Such growth can trap moisture, increase wear, and mar the appearance. Light cleaning using soft brushes or low‑pressure washing can clear it. In extreme cases, chemical treatments may be applied, but care is needed to protect tile surfaces and adjacent landscaping. Often, the presence of growth signals moisture retention in other parts, so cleaning is only one part of the solution.

Efflorescence or Mineral Deposits

Some tile types, especially concrete tiles, may show white, powdery deposits on the surface. This happens as moisture evaporates and leaves behind mineral salts. Though mostly cosmetic, it can indicate recurring moisture issues or high salt content in the exposure environment. Low‑abrasion cleaning or mild acid washes may remove deposits, but you also check for sources of repeated wetting, such as poor drainage or adjacent surfaces spraying water onto the roof.

Structural or Support Issues

Tile roofs are heavier than many other roof coverings. If the roof structure was not designed or reinforced to carry weight with dead loads and live loads (snow, maintenance walking, debris), sagging or cracking may appear over time. In those cases, repairs may include reinforcing rafters, replacing damaged decking, or reducing weight in the system. Tile sections may be reset after the structure is stabilized.
