When there is water leakage in our house, it will have a great impact on our living room, especially long-term water leakage will also have a certain impact on the house.

Therefore, after water leakage occurs in the house, we need to repair it immediately. This is the best way.

Let’s talk about how much does it cost to repair a roof leak?

How to repair roof leaks?

How much does it cost to repair a roof leak? 1. The cost of repairing a roof leak mainly depends on whether it is a partial repair or an overall repair. The cost and cost of the overall repair are higher than that of the partial repair. If the overall repair is used, SBS rolls are usually used.

The specific cost is fixed based on the quality of the rolled material. Regular companies charge 25-50 yuan per square meter, or they can use sunburn to waterproof. This type of waterproof material is a kind of heat insulation and waterproof material.

The cost of integrated materials is between 25-35 yuan per square meter.

2. For commercial buildings, the warranty period of the waterproof layer on the roof 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. The developer is obliged to repair it free of charge. You must contact the developer as soon as possible.

, requiring them to repair it immediately to prevent the developer from delaying it beyond the warranty period and causing them to bear the repair costs themselves.

3. If the roof leaks during the warranty period and the developer fails to fulfill its obligations, then complain to the Consumers Association, Housing and Urban-Rural Development Department, Quality Supervision Department, etc. If the other party still fulfills its obligations after complaining, find the news media to expose them. At the same time,

Be prepared to resolve the matter through judicial means.

4. If the roof leaks after the warranty period is exceeded, the developer will have nothing to do. Since the roof is publicly owned, it is the responsibility of all owners.

If the leak is not serious and can be repaired with minor repairs, then all owners will discuss how to share the repair costs. Once they agree, they will collect the money and find the property management company to repair the problem.

If the water leakage is serious, such as the roof of the building is severely cracked, then major repairs are required. First apply for the major repair fund. If the application is approved, the owner will not have to bear the repair costs.

Roof leakage repair method 1. Repair the seams. Most roof leaks are caused by cracked seams. You need to fill the seams with Yijia leak-proofing paste and wait for them to dry before proceeding to the next step.

(If the seam is less than 1MM, no sealing paste is required.) 2. Water-based waterproof paint or wall-penetrating transparent waterproof material can be applied twice, completely. If the seam is only painted, the width should be more than 20 cm.

This ensures adhesion.

Waterproof coatings are penetrating and bonded, and have good elasticity, so they have a long service life.

3. You cannot get exposed to rain within 12 hours.

If the roof material is special, if it is rubber or other materials that are not suitable for waterproof coating, you can choose other waterproof materials.

For example, if the surface of the ceramic tile is a waterproofing agent that will not continue to break and crack, you can use a waterproofing agent to waterproof the surface, and use a leak-proofing paste at the gap for combined waterproofing.

4. It has not been done before and it is a new cement roof. The appropriate method is to apply primer first and then choose a more qualified SBS waterproofing membrane to lay it over.

5. We have done it before. Most of them were paved with SBS waterproof membrane. If it is more than six or seven years ago and the surface is severely damaged, we can only re-pave it with SBS.

If the time is short and the damage is not severe, then buying one or two barrels of oil-based polyurethane waterproof coating and applying it over the damaged area will last another two or three years, saving time, money and effort.

6. Generally, the leakage points on the roof are at the drain openings, joints and other modeling parts. These details must be taken care of during construction, which will be much safer.

If you do it yourself, the effect will not be good, and later maintenance will be troublesome and affect the overall effect. If there are any problems, you need to find a professional maintenance team to deal with them.
