The house is really scary if it leaks, which can cause mildew at least and peel off the wallpaper and discolor the paint. It is not easy to plug the water leakage, don't be afraid of the water leakage in the house, teach you how to check and deal with it: if the house is leaking, first of all, you should first clarify the following common leakage parts:

If the roof panel is made of waterproof layer, the waterproof layer may be aged and cracked, and rainwater seeps out through the waterproof layer and roof panel; If the roof panel is not waterproofed, it relies on its own concrete and surface mortar to waterproof, due to the influence of temperature difference, cracks will appear in the concrete and surface mortar of the roof panel, resulting in water seepage; The connection between the periphery of the roof panel and the parapet wall is not treated well, and it is easy to cause water seepage; The waterproofing of the connection between the roof and the drainage outlet is not in place, which may also cause water seepage (the technical term is called the detail is not well treated); The perimeter of the window is not done in accordance with the regulations, and there is water seepage between the perimeter of the window and the wall; There may be holes in the masonry of the exterior wall, such as the horizontal rod hole of the scaffold, which is not sealed and compacted during plastering, causing water seepage; During storms, rainwater may pour in from the bottom of the window sash. How to deal with water leakage in the house: when the outer wall of the rain stops slightly dry, pay attention to carefully check the external wall and roof, and the damp traces are the leakage parts, which can be photographed**; It is necessary to grasp the time well, observe diligently, and after being dried by the sun or the wind, you will not find any traces; It's important to take a close look at the cracks in the roof; You must pay attention to safety when viewing and do not take risks; After preliminarily confirming the leakage by yourself, ask a professional to carry out waterproof repair.

Professionals carry out waterproof repair, and it is recommended to contract labor and materials; According to the regulations, the waterproof warranty period is 5 years, and the roof is waterproof, which must be carried out after the roof is completely dried, and the residual water in the roof panel must be dried.

Water leakage on the top floor of a building can be divided into two main causes: external and internal. Some of them are due to external reasons, that is, because of the unreasonable roof structure, and in the past, the exterior walls of some old buildings were caused by water seepage after rain or mold on the walls due to their concrete slabs. Comparatively speaking, most of the internal causes of water leaks on the top floor of buildings are due to problems with the waterproofing layer or various pipelines.

The house is old, the house has been lived in for a long time and there are no good maintenance and maintenance measures, and the waterproof material of the roof layer of the house is aging and damaged, then the house leakage is also a normal reason. There are a lot of plants planted on the top floor of some houses, which actually has a certain impact on the waterproof materials of the house. It's not normal for builders to cut corners and use low-quality waterproofing materials so that the house doesn't leak, but with the current strict national construction quality supervision department, this happens less and less.

Most of the water leakage caused by decoration is caused by changing the layout of the house and drilling holes, and most of the water leakage in the building is caused by structural cracking and pipeline damage caused by external forces. If you want to distinguish the leakage, you can make an appointment with the decoration company and the property management office to check the site of your house, it is best to see the location of the leakage point, and confirm whether there is a hole punching and demolition around the leakage point during the decoration. If there is a crack in the wall near the leakage point, or a water leak in the position of the exterior wall, it is basically a crack in the building structure, which is a problem of the house, and if it is a new wall, it is definitely a decoration problem.

Roof leaks can be detected by:1Observe the roof:

On a rainy day or just after rain, look for water stains, water stains, or water droplets on the roof, which are signs of a water leak. 2.Check the ceiling:

If there is a leak on the roof, there will also be water stains, water marks or water droplets on the ceiling, and the leak can be determined by checking the ceiling. 3.Check the roof drainage:

Roof drainage systems include drain pipes, drain outlets, etc., which can also cause roof leaks if they are clogged or damaged. 4.Use the smoke test:

Lighting some smoke on the roof and observing where the smoke is flowing can determine the location of the leak. 5.Hire professional inspectors:

If the above method does not determine the location of the water leak, you can hire a professional inspector to use equipment such as an infrared detector to determine the location of the water leak.

To detect roof leaks, you can try the following:

1.Watch for water marks and water stains: After rain falls on your roof, carefully look for any water marks or signs of water stains in your room. These may manifest as water stains, fading spots, dripping marks, or mold growth.

2.Check the appearance of the roof: Using a ladder or climbing tool, check the appearance of the roof.

Look for any suspicious areas, such as broken tiles, detached roofing material, cracks, or defects. Watch out for possible water leaks** such as chimneys, ventilation ducts, skylights, ridges and corners.

3.Conduct a water test: When it's not raining, you can use a water pipe or water source to simulate the effect of rainfall.

An assistant stands on the roof and slowly injects water into the expected leaking area, while you watch indoors for potential signs of water seepage. This cover requires careful observation and patience to pinpoint the location of the water leak.

4.Hire a professional: If you're not sure how to detect or fix a roof leak, it's best to hire a professional roof repair company or architect to do an inspection.

They have the experience and professional equipment to detect water leakage problems more accurately and provide appropriate solutions.

Regardless of the method used, ensuring safety is paramount. If you need to climb or perform complex inspections, be sure to take appropriate safety measures and follow the relevant operating procedures.

Roof leaks can be detected by: Respectfully.

1.Observe the ceiling: If there is a leak in the roof, there are often traces such as water stains, water stains, or watermarks on the ceiling. These marks often indicate a hole or leak above the roof.

2.Check the roof drainage system: The roof drainage system includes drains and drainage pipes.

If there is a problem with the drainage system, such as a clogged drain or a damaged drain pipe, it can lead to a leak in the roof. Therefore, checking if the drainage system is working properly is also a way to detect roof leaks.

3.Check the roofing material: Aging, breakage or cracks in the roofing material can cause the roof to leak. Therefore, checking the condition of the roofing material is also a way to detect roof leaks.

4.Water Test: This method involves placing some water on the sloping part of the roof and observing whether the water flows into the house. If water flows into the house, it is a sign that there is a hole or leak in the roof.

In conclusion, detecting a roof leak requires a combination of factors, and if you can't determine the location of the leak yourself, it's best to ask a professional to detect and deal with it.

See if the roof has lines. 2. See if the old waterproof layer is aging. 3.

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.

1. Carefully find the seepage points and cracks on the roof, because the water flows to the low place, so the tomb is generally from the high to the low place to find the leak. Check whether there are cracks on the roof, whether the waterproof layer is aging, whether the waterproof effect is still there, and whether there are bubbles entering the waterproof Wang Ming membrane.

2. After finding the leakage point, you need to remove 3 cm from the leaky part of the roof, then clean the crack and dirt with water, and then use asphalt to water or scrape the seal. If the crack width is larger, you can chisel a V-shaped seam with an upper width of 20mm, and then fill it with waterproof material.

3. If the roof of the tile is leaking, you need to remove the moss or grass on the tile, replace the damaged tile, and pay attention to the joint part of the tile.

If the roof leakage area is too large and there are many leakage points, it is recommended to ask a professional waterproofing company to deal with it, which requires professional tools and techniques to fix it once and for all.

Roof leakage is a quality problem and is within the warranty period, and should be dealt with by the developer; If the warranty period is exceeded, it can be reported to the owners' committee or the property management unit to request compensation, which is generally handled by the owner of the house; If it is caused by the decoration and use of the upper and lower floors, it is generally handled by the residents of the upper and lower floors.
