Does the roof leak belong to the scope of property maintenance?

Roof leakage belongs to property maintenance. Roof leakage belongs to the warranty scope of the construction unit and is solved by the property or developer. If there are other reasons that can't be solved, it should be paid from the housing maintenance fund and the money should be applied to the housing management department. If there is no money, it will be shared equally by all the owners of the leaky building.

The expenditure of property maintenance costs depends on the agreement of the property service contract. The maintenance of the * * * parts of the property and the facilities and equipment used by * * * after the warranty period expires, if there is an agreement in the property service contract, such agreement shall prevail. There is no agreement, from the property special maintenance funds charged. The same is true for repairing leaking roofs.

What are the causes of roof leakage?

1, the pipeline caused the roof to leak. Because every floor has to be connected by pipes, it may be because the contact between the pipes and the floor is not completely closed, resulting in water leakage on the roof. If it is the problem of superstructure construction, find the other party and let them do waterproofing.

2. Floor structure problems. It may be because of age or quality that the floor has problems in use, which leads to water leakage.

3, the upper structure construction damage waterproof layer. The solution is to negotiate with the other party to repair the waterproof layer, which can solve the roof leakage problem.

What waterproof material is used to make up for the roof leakage?

1, elastomer polymer modified asphalt waterproofing membrane SBS, the waterproof performance of this material is not bad, the service life is about 15 years, but the actual service life is related to the construction level, so it is no problem to use 10 years well. If you can't do it well, you will fail in two or three years. If this material is exposed and needs metal or rock side, PE film is not recommended to be exposed, otherwise the waterproof life is only about 4 years. This material is mainly used in cold areas in the north.

2. Plastic modified asphalt waterproofing membrane. The difference between this material and SBS is that SBS is suitable for northern cities and APP is suitable for southern regions. The aging resistance of APP is better than SBS.

3.Tpo waterproofing membrane is characterized by exposure, light weight, good weather resistance and material life of 30 years. However, the waterproof life is related to the construction technology. If the roof shape is too complicated, it is not recommended. There are two construction methods of this material: full bonding and mechanical fixation. If it is fully bonded, the requirements for adhesives are higher.

4, PVC waterproofing membrane, the comprehensive performance of this membrane is not as good as TPO, first, it is not environmentally friendly, and second, it will release plasticizer after a long time, and the material will become more and more brittle.

5. The service life of EPDM waterproofing membrane is as long as 40 years, and it has excellent weather resistance, but it is not widely used. Because this material is sticky, it has extremely high requirements for glue, and there is very little glue that can meet the requirements, so it often bubbles and degums soon and loses its waterproof function.

6, polyurethane waterproof coating, waterproof performance is good, but it can't be exposed to the sun, and its life is generally not more than 2 years. It is usually used in conjunction with high-scoring waterproofing materials, such as TPO waterproofing materials, PVC waterproofing materials, EPDM waterproofing materials, etc.

7. Creep asphalt waterproof coating. When this material is used in combination with modified asphalt waterproofing membrane, the defects can complement each other and improve the waterproofing performance.

8, acrylic waterproof coating, this material is mainly used for metal roof, color steel tile roof, iron roof leakage point maintenance, simple and convenient construction, low cost. Transparent acrylic waterproof coating is used for leakage maintenance of external wall.
