1, the house is old, it has lived for a long time, the maintenance measures are not done well, and the waterproof material of the roof layer of the house is aging and damaged, so the water leakage of the house is also a normal reason. 》》》》》》》》》》》》》》》》》》》

It is not normal for builders to cut corners and use inferior waterproof materials to make the house watertight. However, with the strictness of the national construction quality supervision department, this situation is becoming less and less.

3. Many plants are planted on the top floor of some houses, which actually has a certain influence on the waterproof materials of houses.

4. Because the roof has the characteristics of thermal expansion and cold contraction, it leads to "temperature cracks". As a floor in direct contact with the outside world, it is also obvious that the roof is prone to water leakage.

5. The quality problems of the top floor, especially water leakage, are common in house inspection, and the flue, ventilation pipe, gutter and other parts are prone to water leakage. If the roof is flat-topped, there is a greater chance of water leakage.

How to repair the top leakage;

When there is water seepage and water leakage at the top of roof tile, the source of water and the reason of water leakage should be clarified first. If the tile leaks and there is no concrete interlayer in the middle, carefully check the tile and repair it in place; If there is a concrete interlayer, the interlayer should be waterproof again while repairing the surface of the tile. ""how to repair the roof leakage """

If water seeps in from the outer wall, the outer wall should be waterproof again if conditions permit. If conditions do not allow, the whole inner wall should be waterproof and moisture-proof. Usually, the leakage of the original waterproof house is mostly caused by the poor quality of the waterproof layer, aging failure, rupture and other reasons, so before strengthening the waterproof treatment, the cracks and other parts should be repaired with the plugging king first.

In the case of interlayer, if obvious and few water leakage points can be found on the ceiling, high-pressure grouting method can be used for waterproofing and plugging. In waterproof construction, it is recommended to choose brand waterproof materials, and the construction must be meticulous and comprehensive to avoid future troubles.

Responsibility for building water leakage:

1. For commercial housing, the warranty period of roof waterproof layer is 5 years. Therefore, if the top floor of the purchased building leaks during the waterproof warranty period, it is the responsibility of the developer. Developers have the obligation to maintain for free, and they must contact the developers as soon as possible and ask them to maintain immediately, so as to avoid the delay of the developers beyond the warranty period and lead them to bear the maintenance costs. During the warranty period, if the roof leaks and the developer fails to fulfill his obligations, he should complain to the Consumers Association, the housing construction department and the quality supervision department. If the other party still fulfills its obligations after the complaint, it should find the news media to expose it and prepare to take judicial measures to solve it.

2. For commercial housing, if the roof leaks due to man-made damage, even during the warranty period, the developer is not obliged to give free maintenance, and even if he is willing to pay, the developer often will not give maintenance. In this case, we can only find the destroyer to provide maintenance services, or the property provides maintenance, so that the destroyer can bear the maintenance costs. Specific maintenance services and costs can be discussed and decided with the saboteur. If the other party refuses to compensate for the loss, it will take judicial channels. If the destroyer can't be found, only the owner of the whole building will share the maintenance cost.

For commercial housing, if the roof leaks after the warranty period, the developer is fine. Since the roof is shared by the public, it is the responsibility of all owners. If the water leakage is not serious, minor repairs can be made, and then all owners will discuss the sharing of maintenance costs, and after reaching an agreement, they will collect money to find a property to repair it. If the water leakage is serious, such as the roof cracking, it needs to be overhauled. First, apply for overhaul fund. If you apply, you don't have to bear the maintenance fee yourself. If the application for maintenance fund is not approved, then only all owners of the building will share the maintenance cost.

4. If the property right belongs to the welfare house of the unit and the self-built house leaks, find the logistics department of the unit or the department responsible for housing management and welfare, and apply for maintenance; Some units are inefficient. If you can't wait for the logistics maintenance, you can apply to the logistics department to hire someone to repair it, and then go through the formalities and submit an expense account in the logistics department, which will submit an expense account in the financial department of the unit. This alternative method is effective in some units and ineffective in others.

Top leakage repair

If it is a rented house, the maintenance of roof leakage is entirely the responsibility of the landlord. Therefore, we should contact the landlord in time and urge the other party to complete the maintenance as soon as possible. Some landlords are lazy or ill-intentioned, and will negotiate with tenants to let them hire someone to repair them themselves, and the maintenance cost will be paid by the landlord. Try not to agree to this situation, lest the landlord find fault with it in the future.

6. For self-built houses, if there is water leakage, they must be responsible for maintenance. Minor repairs, you can do it yourself. First, find the leaking place. If the gap at the water leakage is small and it is impossible to pour waterproof materials, dig a V-shaped pit at the water seepage joint with a chisel or grinder, and then pour concrete slurry mixed with fine sand and cement (waterproof coating can also be used) into the pit. The water seepage is slightly higher than other normal floors. If the roof cracks seriously and needs to be overhauled, it is generally only necessary to hire professional leak-trapping personnel to repair it.
