Fixing a Roof Tile Crack

Access the cracked roof tile on a ladder. Wearing a hard hat and skid-proof shoes while walking over the tiled roof locating the damaged tile reduces the chances of injury.

Brushing the tile surface with a wire brush removes scale, debris and rust, so the crack is visible. Ensure the tile is completely clean before making any repairs. Wipe the tile with a clean cloth.

Load a caulking gun with roofing cement. Position the nozzle directly above the crack on one end of the tile. Insert the caulk into the crack until you reach the other end of the tile, sealing the crack completely.

Insert a putty knife’s tip into the container of roofing cement and scoop a small amount. Rub the cement over the crack’s surface, pressing it gently with your gloved hand pushing it in the gap, removing trapped air. Let the cement cure.

Sanding the cured cement’s edges around the crack with fine-grit sandpaper smoothes and blends it with the surrounding tile surface. Wipe the surface with a damp cloth.
