Try to first determine the location of the leak, from the attic.Although it rarely happens, but sometimes you can see a ray of sunlight streaming through the
hole.However, most of the leak at such inspection is not found.
Try searching skin moist areas, but rather look for the leak in the rain.In this case, you can do only a lantern or lamp cord (if you're lucky, of course).Wet spots darker than dry wood.Although leakage is not usually the case where there are wet spots, but at some distance from them.The moisture in this case simply flows over the casing or the rafters and then drips onto the ceiling somewhat below the actual spill area.Do not forget to check the insulation in place the potential for leaks or damage wet areas.
Once the spill area, measure the distance from this point to the edge of the roof, as well as to the gable or to the nearest exterior wall.Measure the distance on the tiles, in order to find the damage.
Keep in your mind that if wiring sewer pipes, water or water heating is done through the attic, the cause of damp stains on the ceiling can be leakage of pipes, not the roof.
Damaged place you need to look outside.Inspect the roof, looking primarily cracked or broken tiles.Then check the waterproofing of joints for its lag from the wall of the chimney or dormer.You can ask anyone in the family to help you.To do this, let it climbs into the attic and monitors the location from which will flow water while you are watering the roof with a hose.
