Such an inspection should be carried out immediately after rain.
- Next, inspect the structure outside. Explore tiles for cracks and shifts. Inspect all joints and junctions of tiles to other roof elements (antennas, chimneys, multiple ribs).
- Lift edges of adjacent tiles (above and right ones) with the help of easy driving in wooden wedges. With the help of a trowel hook the damaged tile and pull it out of its row through efforts "to the left and up to yourself".
- Place a new tile instead of the old one, setting it back in the "lock". Remove wedges. The operation can be carried out by two people, when your assistant lifts adjacent tiles at the bottom (attic), you can easily pull out the damaged one and make the replacement.
