    The minimum slope or pitch for a tile roof will depend on the exact profile of tile you are using. The lowest any tile can usually go is about 15 degrees, but some must be steeper. Check with the manufacturer as to their recommendation.
  • Question
    What is the main cause of leaks on a tile roof?
    Community Answer
    Cracked mortar allows a tile (or more often, several) to break loose, exposing areas near the top to water flow. As with any leak, try looking from underneath your roof to find the precise source/location.

    If you have moss or specific debris you are trying to remove from the surface, yes. Otherwise it is unnecessary.
  • Question
    My tile roof is 2 years old and has always left a thin coating of mud (the color of the tile) on the inside courtyard floor after a rain. It seems to be getting worse. Is this a common characteristic?

    Is your roof concrete tile or clay tile? This typically means that your tile is eroding, which is generating debris and depositing it on your courtyard floor. Depending on the age and style of the tile and the level of degradation, you may be able to further preserve the existing tile with a sealer/coating.
