Can I find a property repair for the water leakage on the top floor?

You can find a property repair if the top floor leaks. But we should pay attention to determine whether it is within the warranty period. The waterproof warranty period of a building is generally five years.

1. If the top floor leaks during the waterproof warranty period of the building, you can directly find the real estate developer to fill the leak.

2. If the waterproof warranty period of the building has expired, the property can be responsible for the top-level leak-patching, and the expenses arising from the leak-patching will be deducted from the house maintenance fund, because the roof leak-patching belongs to the scope of use of the house maintenance fund.

Causes of roof leakage

1. Many plants are planted on the top floor of some houses, which actually have a certain impact on the waterproof materials of houses.

2. The house is very old: if you have lived in the house for a long time and have not taken proper maintenance measures, the waterproof material of the roof layer of the house is aging and damaged, then the water leakage of the house is also a normal cause.

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.

Maintenance method of roof leakage

1, joint repair, most of the water leakage on the top floor is cracks, so it is necessary to fill the gaps with Yijia patch, and then proceed to the next step when it is dry. (If the joint is less than 1MM, no leakage sealant is needed. )

2. Brush it twice with water-based waterproof coating or transparent waterproof material with wall permeability, which is comprehensive. If the gap is polished, the broadband should reach more than 20 cm. This ensures adhesion. Waterproof coating is permeable and bonded, with good elasticity and long service life.

3. If it has been done before, most of them are paved with SBS waterproofing membrane. If it has been more than 67 years and the surface is seriously damaged, SBS can only be resurfaced. If the time is short and the damage is not very severe, then buy one or two barrels of oily polyurethane waterproof paint and apply it on the damaged place once, which can be used for two or three years, saving time, money and labor.

4. The leaking point of the roof is generally the shape of water outlet and joint. These details must be handled well during construction, which will be much safer. The effect of self-made is not good, and the later maintenance is troublesome, which affects the overall effect. If there is any problem, I need to find a professional maintenance team to deal with it.

5. 12h is not allowed to get caught in the rain. If the roofing material is special and rubber is not suitable for waterproof coating, you can choose other waterproof materials. Such as waterproofing agent, if it is the surface of ceramic tile, it will not continue to break and crack. Waterproofing agent can be used to make the surface waterproof, and leak-trapping paste can be used to combine waterproofing at the crack.

6. If it has not been done before, and it is a new cement roof, it is appropriate to coat the bottom oil first, and then choose a more qualified SBS waterproofing membrane to pave it again.
