The bathrooms, the kitchen, the bedrooms?

How to fix a leak if the roof has cracks or fissures

  • Step 1. Spray the roof with water. Then prepare a mixture that should be as thick as baby food and includes: cement, marble, a sealant and water. Any building supply store can advise you on the best options for liquid sealant for waterproofing roofs.
  • Step 2. Make the mixture to seal or cover cracks. You need a 20 litre bucket that fills half of the water. Use 3 liters of sealant, 4 kilograms of marble and 4 kilograms of gray cement.
  • Step 3. Distribute the mixture. Once you have made the sealant mixture you must distribute it evenly with a broom over the entire surface of the roof. If it is only in small areas, a brush is enough to spread it.
  • Step 4. Wait for everything to dry. It will take about 12 hours.

The good thing about this mixture is that it will penetrate through the crack and seal deep down. Say goodbye to the leaks!

How to fix a leak if the roof has deteriorated tiles or sheets

  • Step 1. Check where the drip is coming from. Leaks may appear a few centimeters higher than where the leak falls in the case of roofs with a certain slope.
  • Step 2. Detect if there are broken or detached tiles. This is easy. Just touch them and pull them with medium force, if you see it moving... that's it. Once located, they must be removed.
  • Step 3. Waterproof. Underneath the tile you will probably find cracks. It is necessary to place a special waterproofing that they recommend in a construction shop.
  • Step 4. Place the tiles. Place the new or repaired tile on top of the waterproofing. Verify that it is in place and fits with the others before fixing it with cement.
  • Step 5. Check the joints and seal them. The most vulnerable areas on the roofs are those where antennae, skylights, ventilation systems and other applications involving caulking are attached. Putty deteriorates over time and needs to be reinforced. Remove the old putty with a spatula and spread the new putty with an applicator.

When performing these tasks, take the following precautions: gloves, non-slip rubber shoes, appropriate long-sleeved clothing that protects you from the sun, a ladder and safety cords.
