If you have a tile roof, it’s not a matter of IF it will leak, it’s a matter of WHEN it will leak.
Most people don’t know that tile roofs require maintenance in order to avoid leaks.
Flashings: Must be kept clean to avoid debris dams which lead to leaks
Broken/slipped tiles: Broken tiles need to be replaced & slipped tiles need to be reset and sealed
Seals & Gaskets: Seals and gaskets for pipe vents, and junction points in the roof also have a lifespan and will need replacing at certain intervals throughout the life of the roof to avoid possible leaks
