You just need a flat pry bar which should be used to lift the tiles on either side of the damaged tile. Now you can easily take out the damaged tile. In case the tile is nailed down, then remove the nail with the help of a hammer before you slide out the tile. After removing the damaged tile, place the new tile in its place and now remove the flat pry bars which are holding the tiles and let it fall in its place.
This can also be done as an added protection from severe heat and cold. In some countries, either the heat is unbearable or the cold. This roofing would not only give the building a new look, but also protect you from the unbearable heat or cold. Tile roof repair can be easily done instead of tile replacement if it is just a small crack thereby saving you money and time. You can mix some mortar and fill in your crack and just coat it with the tile colour paint.
