The most common problem with tile, concrete tile, fiber cement, and other types of masonry roofing is cracking. For anything but an occasional cracked or broken tile, hire a roofer.
To repair small holes or cracks in tile:
1) Scrub the area with a wire brush.
2) Fill the area with plastic roofing cement to seal or join the crack.
To replace a tile that is severely cracked or broken:
1) Carefully pry up the tile (or tiles) just above the cracked or broken one.
2) Break the faulty tile, and remove the pieces. Also pry or force out any nails.
3) Spread a small amount of roofing cement along the underside of the replacement, and slide it into place. Adhesive, rather than nails, will hold this tile.
