What are the methods for repairing roof leaks?

Repair method for roof leakage:

1. In rural areas, there are still a large number of tile houses. When roof leakage occurs due to tile damage, simply replace the tiles. This step is also known as "flipping leakage". For some buildings with red tiles that have roof leakage, simply remove the grass, moss, or dust on the tiles and replace them, and the leakage prevention effect is the same.

2. For flat roofs with obvious cracks, use tools to mortise and tenon the cracks into a zigzag shape, apply sealant, and wrap them with waterproof rolls above and around the cracks. If the cracks are relatively small, only using the "Leak King" after cleaning the roof can achieve the purpose of repairing the leaks. To enhance the leak prevention effect, another layer of waterproof membrane can be laid. If there is a large area of water leakage or multiple leakage points on the roof, professional personnel should first check for cracks. After dealing with the cracks according to the previous plan, waterproof membrane can be laid on the entire roof. To enhance the waterproof effect, insulation board can also be laid. Due to the height of the insulation board being more than 20 centimeters, it can achieve the dual effect of protecting the waterproof layer and thermal insulation. Families who are unwilling to use insulation panels can consider using steel wire mesh concrete (known as steel wire mesh fine aggregate concrete in professional terms), which also has a good leak proof effect.

If there are cracks or water seepage on the wall, a professional construction team will usually use a suspended basket and have maintenance personnel carry out the construction on the exterior wall. The solution for dealing with roof leaks is: for large cracks, you can use Leak King, and for small cracks, you can use glass glue to repair the leak. When repairing, use exterior wall waterproofing agent and spray it a few times before it works. Due to the need for high-altitude work to repair cracks on the exterior walls, citizens must hire a professional construction team to handle it in order to prevent safety accidents.

4. Foundation subsidence leads to wall cracking, which is still developing. The subsidence of the foundation is a relatively slow process, with an annual variation of about a millimeter, but when reflected onto the roof, although it has little impact on the overall structure of the house, a few millimeters can cause rain leakage. Suggest adding a layer of insulation on top. In addition, waterproofing agents are mainly used for walls, and the effect on roofs is not very good. So if the roof leaks, asphalt and felt should be used, which is easy to operate, but the service life is short, and it needs to be redone every 3-5 years. Actually, using the method of three oils and two felts for overall paving is better. Adding insulation layer is costly, equivalent to adding another layer of simple house.

5. Note that before waterproofing and leak repair construction, the roof must be dry because the moisture on the roof does not evaporate, which will lift up the new waterproof layer and immediately render the waterproof effect ineffective. Therefore, construction should not be carried out on rainy days, and construction can only be carried out after the sun has dried the moisture.

I get annoyed when it rains, with water leaking from the ceiling, windows, and windowsills. Prepare a basin to fetch water, you can't even sleep well at night. I repaired it several times, but it didn't work. The house has become damp and the walls often grow hair, which is a troublesome issue. Is there any way to solve this problem.
