The expense and difficulty of installing a tile roof is not to be taken lightly. The earlier problems are discovered, the easier they are to fix. Keeping the roof clean and in good repair is the key to making it last. "When you have your tile roof cleaned, you may want to consider taking some extra steps which can prevent a very tragic outcome. Often times moss, dirt, pine needles or whatever else it may be, start to build up underneath the tiles along the walls and in the valleys," according to the tile roof cleaners at Practical Pressure.

Use a hammer to lightly tap a chisel along the grout holding the broken roofing tile in place. Run the chisel along areas of adhesive until the tile is free and can be thrown away.

Clean out the area that held the tile with a small broom or cleaning brush. Remove any chunks of adhesive or grout to prepare for a new tile.

Spread a layer of tile glue 3 mm (1/8 inch) thick along the underside of the tile using a putty knife. Leave the last 1.2 cm (1/2 inch) at the edge of the tile free of adhesive.

Press the new tile into place. Apply gentle pressure to evenly spread the glue.

Give the glue 24 hours to dry. Apply a new border of grout using a small trowel.


Work carefully around the other roofing tile. It breaks easily.


Use caution when working from the roof level.
