Leaking water and moisture from the roof

Locating the spot on the roof from which rain filters in is a difficult task. You can try by measuring the distance between the spot and the corners of the ceiling and looking for the match on the covering surface. Going up the slope, you should find the place of infiltration.

  • The connections between the tiles, if they are not performed in a workmanlike manner;
  • The frame of the skylights, if not installed correctly;
  • The ridgeline, if the mantle is not homogeneous;
  • The perimeter of the flue, if it is not well sealed.

To remedy serious infiltrations on the flat roof, it is necessary to further widen the edges of the crack using, if necessary, a chisel. It fits fibreglass adhesive tape and fills it with sealing putty. For a better seal, it is advisable to apply a layer of waterproofing paint.

If it is an association, contact it to have the repairs carried out otherwise if the responsibility is yours, you can safely proceed to repair your roof yourself.

Step 2: Carefully identify the correct position in which the point is located. In fact, the water could drip into a very different area from that where the leak is located. For this reason, enter the attic or under the roof and try to identify the hole from which the water starts to drip.

Step 3: If the roof is concrete, it may be flat. It is necessary to remove the tiles and eventually replace the plywood.

Step 4: Lift the tiles from the roof with the help of a metal or wooden rod. Remove the tar paper and inspect the plywood.

Step 5: If the plywood is visually damaged, you will need to replace it. To do this, cut out the damaged part of the plywood. Remove the old plywood and carefully measure the affected area. Cut the new plywood to the exact size of the hole we previously cut. Position the new plywood carefully making sure there is no gap in the cover or overlapping edges. Cover with tar paper and carefully reposition the tiles.

Attention: As usual, our advice is to pay the utmost attention when using the ladder and when you are on top of a roof!
