The most leaky source and the most seepage is the roof. These are roof problems that often occur.
Improper Roof Construction
Generally caused by the slope of the roof that is too gentle (less than 25˚). Strong winds will push rainwater into the house through the cracks of the bottom of the tile, wet the ceiling, and even water can drip through the walls.


• Rearrange roof slope construction by completely removing the roof. The ideal roof slope to flow rainwater smoothly is 30˚- 40˚.
• Give plastic or aluminum foil anti-leak coatings to the bottom of the tile. With this layer, the water will be held back by a layer of plastic and then flowed down to the gutter. This solution is usually temporary.
Broken or Broken Tile
• Broken or broken tiles can be crushed by trees, crushed by wood, or trampled on.
• Other causes are the age of roof tiles (especially concrete roof tiles), so that the surface of the concrete roof is eroded and cracks.


If the tile breaks, it must be replaced with a new tile. However, if it is cracked, there are 3 treatments that can be done.
• If the crack is not too large it can be overcome by coating waterproofing (anti-leak coating). Use waterproofing plus fiber. Cut the fiber in the tile area according to size, then spread with a waterproofing solution.
• If the crack is large enough, you should replace it with a new tile.
• Give plastic leak proof sheets or the like at the bottom of the tile. With this layer, the water will be held back by a layer of plastic and then flowed down to the gutter.

Suction tiles

• The roof is too tilted (slope is greater than 40˚) and causes the tile to detach from the batten stand.
• Installation of tile is not appropriate, so that when there is vibration (for example due to heavy rain or strong winds) the tile sags from the batten holder.
• The roof frame is porous because it is eaten by age or eaten by termites, which causes the lath where the tile holder is broken.
• Rearrange roof construction by totally disassembling so that the roof slope is ideal, ranging from 30˚ to 40˚.
• If the architectural design of the house requires the slope of the roof to be made more than 40˚, choose a tile equipped with nail holes to lock the position of the tile so as not to sag.
• If the roof frame is partially porous, replace it with a new roof frame on the porous frame. If everything is porous, then dismantle it completely.
• If the condition of the batten and tile is still good, but the roof tile is loose due to the carelessness of the craftsman who does not connect the tile to the batten, then the solution is to return the tile to its original position.
