Roof leakage causes, roof leakage what causes

Roof leakage is caused by natural aging, cracking, shrinkage, or quality problems during construction, resulting in short-term roof leakage, and there are many reasons for roof leakage. If the waterproofing material is laid without taking into account the drainage problem; Secondly, before brushing the waterproof coating, the base layer is not treated as required, resulting in a gap in the waterproof layer.

Solutions to roof leaks

Roof leakage solution, waterproof paste repair. Partial repair with waterproof paste is the easiest way to do it yourself. Specifically, we buy finished waterproofing paste for outdoor use and repair the leaky parts of the roof.

In this repair method, we first need to find the specific location of the roof leakage, and the common location is the crack in the roof.

You can focus on checking the root of the parapet wall of our roof, and if the roof has pipes, check the roots of the pipes. Once you have found these locations, apply waterproofing paste to the gaps, fill the gaps with waterproofing paste, and then paint the flat surface again. In this way, the partial repair with waterproofing paste is completed.

Asphalt oil. In fact, the most traditional way to repair the leakage on the roof of a bungalow is to fill with bitumen oil. I'm sure many friends have seen it.

In many waterproofing repairs, asphalt is boiled on site, and then the asphalt is melted into an oil state, and then the joint treatment is carried out. This is also a more traditional and achievable method of repairing a leak in the roof of a bungalow.

Specifically, we first find the cracks in the roof, which is the location that causes the water leakage, and then fill the melted asphalt in the area. After the gap is filled, it is recommended that you spread a layer of asphalt oil on the plane to achieve the overall closure. The effect of this repair is also very good.

1. After a long time in the house, the top floor of the house is very prone to water leakage, this is because the house is too long, resulting in the loss of waterproof protection done before, so the rainwater will leak down from the cracks in the wall. In particular, the leakage of the old house will become more and more serious, if it is not treated, it will be heavy rain outside, and it will rain lightly in the house.

2. Some residents will build vegetable gardens and flower stands on the top floor, but when designing these, they do not do a good job of waterproof isolation layer, so the water floods through the floor, which will cause water leakage on the lower floor, and some people even make a pool on the roof, if this is not waterproof, the erosion of the lower layer will be very serious.

3. If there is a leak on the roof of the new house, it may be a problem with the quality of the project, due to cutting corners in the building materials, or the waterproof project may not meet the standard. In addition to water leakage, there must be other quality problems in this situation, which will be more troublesome to solve.

Answer: 1. It is because of the aging of the waterproof layer, thermal expansion and contraction that leads to the destruction of the waterproof layer, the deformation of the socks under the foundation, the cracking of the roof, the poor drainage, the solar water leakage, the roof has a thermal insulation draft to let the layer lead to string water, and the waterproof leakage treatment is not in place, resulting in more serious water leakage, etc., which is the common eight warning of roof leakage.

There are many reasons why a roof can leak, and here are some possible ones:

1.Poor quality of building materials: In order to reduce costs, developers use poorer quality building materials, resulting in poor roof waterproofing performance.

2.Damage to the roof waterproofing layer: The waterproofing layer of the roof is damaged, such as long-term exposure to ultraviolet rays, the impact of storms, etc., resulting in the aging and cracking of the waterproof layer, resulting in water leakage.

3.Poor roof drainage: Clogged or poor roof drainage can cause rainwater to accumulate on the roof and cause water leaks.

4.Improper roof joint construction: Improper roof joint construction, such as telescopic hall joints, cornices and other places are not properly treated, will lead to roof leakage.

5.Poor construction quality: Poor roof construction quality, such as not doing a good job of waterproofing layer, not having a perfect drainage system, etc., can also lead to house fibrillation and hidden roof leakage.

As for the solution to a leaky roof, different measures can be taken depending on the specific situation. For example, replacing building materials, repairing waterproofing, improving the roof drainage system, and improving the roof node structure. At the same time, it is recommended that users pay attention to waterproofing when decorating the house and try to avoid water leakage.

When it rains in a self-built house, it rains lightly outside the house and locally rains heavily inside the house; Heavy rain outside the house, waterfall inside the house; Commercial house, upstairs bath, downstairs rain! The roof is not done, the water seepage is light, and the leakage is the most worrying. Especially in commercial housing, the roof leakage is generally the bathroom and kitchen, and the leakage upstairs is domestic sewage, not to mention how disgusting it is.

Other people's houses can not only maintain on the roof, grow vegetables, raise fish, and build swimming pools, but the most frustrating thing is that they actually row a boat on the roof, but your house leaks into a dog?

Zhejiang rooftop fish ponds, fountains, boating.

There are generally two reasons for the leakage of self-built houses: one is that they did not do waterproofing, and the other is that the construction quality of the contractor is not good and he is pitted.

There are generally two reasons for the leakage of the roof of the commercial house: one is that the waterproofing upstairs is pitted by the construction team, and the construction is not done; The other is that the developer's floor construction is not up to standard, and the waterproofing of the hardcover house is not done or the construction is not up to standard.

Today, I will teach you how to prescribe the right medicine and remedy the leakage of the roof of commercial houses and self-built houses.

1. There are 3 ways to repair roof leakage.

1. The first is to repair the surface of the water.

To put it simply, it is to open the roof, find the leakage, and then redo the waterproofing membrane and then fill the rigid roof. The most difficult thing is to find the leakage, because the leak of your home is not necessarily the place where the roof leaks, the water will be free between the roof slab and the waterproof layer of your house, and the leakage point of your home can only represent that point's own concrete is not compact, and the water is free to that point and leaks down. It doesn't mean that the leak in the roof is in that place.

So most of the roof needs to be turned over to be done once and for all. You need to use the property for maintenance**, and the cost is too great.

2. The second method is backwater repair.

The only solution is to inject waterproof glue (commonly known as waterproof injection) into the leaky place of your home, so that the concrete in that place is dense and there is no problem in the short term. But more and more water on the roof will drift away from the top, and one day it will leak somewhere else.

2. Two kinds of remedies for roof leakage of commercial housing:

Compared with self-built houses, once the leakage of commercial housing occurs, it is living in heavy rain every day, however, in fact, the remedy method of water leakage of commercial housing is relatively simple.

Roof leakage in commercial housing mainly occurs in bathrooms and balcony kitchens. Generally, there are two situations: one is serious leakage around the pipeline; Another is the irregular leakage of the entire top in various positions, and obvious cracks can be seen in serious cases.

1. Water leakage around the pipe.

There is a leak around the pipe, and of course the water is not because the pipe is ruptured, but because the pipe is not plugged. Some construction workers plug leaks and make some asphalt perfunctory, and the money is too ambiguous.

The only way to do this is to find a property and go to the upstairs neighbor to make his house waterproof again. But people who have had the experience of finding neighbors to solve problems, especially those who have to spend thousands or tens of thousands of dollars on troublesome problems.

As we all know, finding neighbors and finding a property to solve it is quite a troublesome and long process. So you can treat the symptoms by yourself first, and then grind the property all the time.

1. What should I do if the roof is leaking?

1. If the roof has not been waterproofed before, the leakage should be chiseled into a groove with a depth of about three centimeters, then the groove should be cleaned, and then the asphalt should be poured into the groove, and finally wait for it to dry naturally.

2. If the roof has been waterproofed before, the waterproof layer and leveling layer at the leakage position should be removed first, and the specific leakage location should be found, and the hollow drum should be chiseled clean. The leak is then cleaned up and a millimetre-thick polyurethane coating is applied. If possible, you can also lay another layer of heat insulation board, if you don't want to, you can lay another layer of steel wire mesh fine stone concrete.

3. If the roof is a flat roof, and there are obvious gaps in the roof, the gaps should be chiseled into a "V" shaped groove first, and then the groove should be filled with caulking ointment, and then a layer of waterproof membrane can be laid above and around the position. If you want to strengthen the leak prevention effect, you can lay another layer of waterproofing membrane.

2. What are the precautions for roof waterproof leakage repair.

1. Before construction, the roof must be kept dry, if the moisture of the roof is not evaporated, it will lead to the bulging phenomenon of the newly made waterproof layer, which will affect the waterproof effect of the waterproof layer. For this reason, it is recommended that you do not carry out roof waterproofing and leakage repair construction on rainy days, and should wait for the sun to dry the roof before construction.

2. In order to ensure the waterproof leakage repair effect, it is recommended that you must choose to use regular high-quality waterproof materials for construction, and you should ask a regular and experienced professional team to help with the construction. After the construction is completed, the waterproof test should also be carried out, and the leakage can be considered successful after the test is qualified. 

Water is pervasive, and water flows downward. If you block this place, the water will continue to accumulate and continue to flow, and you will find a way out, and if you encounter a cracked floor slab, it will leak down again. For example, if water leaks somewhere on the top of the balcony, the back water surface is partially blocked, the water may leak down from other places, and the entire balcony roof is blocked, and it may leak from the roof of the living room.

1. Roof leakage caused by poor pipeline contact. There are pipes on each floor, and there is no seal in the contact between the pipe and the floor slab, which causes the roof to leak. 2. Artificially damaged the waterproof material.

Many people like to raise a lot of plants on the roof, so the waterproof material of the roof will be destroyed, and the rain will cause water leakage. 3. The construction of waterproofing is unqualified. In the process of applying waterproof materials, there is no all-round coverage, and there is an uneven phenomenon, resulting in water leakage in the later stage.

Roof leakage is in disrepair, need to be re-covered or tile, just like people will get old with age, the house or machine will slowly age all year round, it is best to repair it as soon as possible, otherwise it will become more and more serious, I hope it can help you.
