Can the roof be repaired if it leaks?

The leaking roof can be repaired. In fact, with the development of this society, there is no need to use such complicated methods to fill the leakage of houses. As long as you know where the leak is, you can choose many waterproof materials to fill the leak.

If it is a large area of cracks, just choose some suitable waterproof materials with good quality. After cleaning the roof with a broom, you only need to brush the leaking place evenly with a brush or roller, and brush it several times after the first time. In this case, it can basically be solved in 5- 10 years.

In addition, if there are not many cracks and only obvious big cracks, it will be easier. There is no need to brush waterproof materials at all, so you can choose to use fire-free baking waterproof coiled material. Just like taping, directly find the location of cracks, shovel off the surroundings with a shovel, then sweep off the dust with a broom, and directly paste the fire-free baking waterproof coiled material to achieve waterproof effect.

What are the solutions to roof leakage?

1. If there is local water seepage on the external wall of a high-rise building, scrape the putty on the internal wall to find out the water seepage, and then remove all the loose mortar in the brick joints. After the cracks are washed clean, caulk them with 1:2.5 cement mortar.

2. When the roof leaks in a large area, but no cracks can be seen, the decorative surface of the external wall should be washed clean first, and then the cationic neoprene polymer should be stirred evenly according to 1: 1 after drying, and then the jointing treatment should be carried out with cement mortar.

3. If there is water leakage under the beam, first clean the cracks in the external wall, scrape off the mortar in the cracks, rinse it off, and then embed it with iron sheets. Then use 1: 2.5 cement mortar for joint filling, and be sure to recess the wall of 10 mm, and finally evenly apply flexible waterproof sealant to decorate the external wall.
