The old house is the kind of folk house left over from ancient times, with wooden structure, brick enclosure and two floors. The floor is all wood, and the beams are under the boards.

Hello! Yours should be on the roof, right? The reason for water leakage is that the tiles on the roof are broken, or individual tiles have slipped for a long time, resulting in gaps between tiles, so that rainwater will penetrate along the gaps in rainy days. Because the roof is a slope, the commonly seen water leakage point below (in the house) is below, and the real water leakage point is somewhere above.

In this case, maintenance should not be complicated, and ordinary bricklayers can do it. First look at the approximate location of the water leakage point in the house, then climb on the roof to carefully check the possible water leakage location, rearrange the tiles and replace the damaged tiles.
