Who to contact for a roof leak? What should I pay attention to when waterproofing roofs?

Generally speaking, if there is a leak on the roof of the house, it is first necessary to find out the cause of the leakage, and clarify the responsible party, which includes the owner, the developer, and the property company. If it is due to water leakage due to the quality of the house, then the developer is required to be responsible for repairs.

If the house has passed the waterproof water warranty period (generally waterproof is five years), then the property management company can apply to the housing management department for the use of the house maintenance ** maintenance. If the roof leakage is widespread and the warranty period of the house has passed, then all owners or the owners' committee should take the lead in asking technicians to solve the repairs, and the cost should be shared equally by all owners.

1. Before the roof waterproofing, the bottom layer should be eliminated neatly, and no dirt, oil stains, etc., until the bottom layer is dry, the waterproof raw materials of architectural coatings can be used, if the natural environment is relatively wet and cold, it is necessary to increase the drying time to prevent the raw materials from peeling. And the waterproof coating should be divided into layers during construction, and generally the lower part can be carried out only after the upper part is dry.

2. When the roof is waterproofed, it can not be carried out in rainy days or rainy and snowy days, it is best to choose sunny weather construction, and pay attention to the construction temperature, generally in summer construction, to ensure that the construction temperature can not be higher than 35 degrees, otherwise the water evaporates too quickly, and the coating film will crack. In winter construction, the temperature is best above 5 degrees, and too low a temperature is very easy to freeze and crack the coating layer, which will endanger the waterproof quality.

3. When the waterproof coating is used and distributed, it must be based on the operation manual, such as the black and white waterproof coating needs to be applied separately and cannot be mixed together to prevent the quality of the material from being endangered. In addition, before the coating film dries, do not crawl on it.

4. If there is a relatively large total area of water leakage or multiple leakage points on the roof, the professional and technical personnel shall first check whether there are any gaps, and after the gaps are dealt with according to the previous plan, the waterproof waterproof membrane shall be paved on all roofs, and the insulation material can be paved again if the waterproof effect is strengthened, because the relative height of the thermal insulation material is about 20 cm, which can achieve the dual effect of protecting the waterproof layer and thermal insulation. If there are cracks and leaks on the wall, under normal circumstances, the technical professional construction team will use the electric hanging basket and the maintenance personnel will work on the wall.

Roof leakage to find a renovation company to solve. Roof waterproofing should pay attention to the selection of material waterproofing membrane and the paving method of waterproof selection. The waterproofing membrane is cost-effective, and the paving method should follow the direction of the flowing water.

If the roof leaks, you should find a developer to solve it effectively; Roof waterproofing must pay attention to the choice of word-of-mouth, better quality assurance of waterproof coatings, and to keep the roof dry before construction, after the completion of the waterproof test.

If the roof is leaking, then you can find a property to solve this problem, you must find a professional master when doing waterproofing, and then the materials used must also be excellent.

Roof leakage, the common method is to lay asphalt, this is generally for the leakage area is relatively small, the construction is simple, and it is relatively cheap. However, asphalt is not subject to the thermal expansion and contraction of the climate, and it is not recommended to repair with asphalt oil in the case of quality requirements; If the roof leaks, if the area is relatively large, the waterproof layer can no longer play the waterproof effect, then it can only be re-waterproofed.

The best material to repair leakage cracks in the roof is to have the following three characteristics:

1. The adhesion ability is particularly strong;

2. Aging resistance, high and low temperature resistance, corrosion resistance;

3. Anti-ultraviolet, acid and alkali resistance.

Your situation should be that there is a crack in the roof, which is why the water seeps. So your roof should be waterproofed. If your home is a new house and has not yet passed the warranty period, it is easy to do, call ** to the property and ask him to call ** to the developer to be responsible for maintenance.

If it is an old house, it is common for the roof of the old house to leak, so please do not panic. If you find obvious cracks, then you can first use plugging materials such as plugging king to plug the cracks, and then use cement-based waterproof paint to coat a waterproof layer around it, and appropriately expand the scope of painting, and then use cement mortar to lay a certain thickness of protective layer. Now there are many waterproof coatings on the market, and the quality is uneven, so we must choose products with better quality, such as Leibangshi's JS flexible waterproof slurry.

If you use fake and shoddy products, you will generally have to repair them soon, so you must pay attention to them and don't be fooled. During construction, we should also pay attention to the construction in strict accordance with the product requirements, and pay attention to protect it after the incident, and do not trample on the waterproof layer.

Choose Raybons flexible waterproof slurry. It can be painted multiple times and fortified in multiple ways. The complete waterproof layer is painted twice, and the total thickness cannot exceed 2mm, and then the cement mortar is applied as a protective layer.

After the protective layer is dried, a complete waterproof layer is applied again, and then cement mortar is used as the protective layer. Then apply a flexible waterproofing paste. This can be repeated 3-4 times to ensure the waterproof effect.

However, the base surface must be treated well, and the outermost layer must be made of cement mortar as a protective layer.

Regarding the question of **, you can first select the material to be used, and then calculate it according to your roof area, mainly to calculate the amount of product. Hope it helps.

Roof leakage, mostly cracks and leakage, it is best to choose waterproof materials with strong flexibility, good adhesion and strong weather resistance, and it is best to choose water-based non-curing rubber asphalt waterproof coating, but it is more expensive to 400 pieces of 20kg a bucket, which can be used in 20 square meters.

Roof leakage, it is recommended to find the cause of the leakage first, then check the number, area, and severity of the leakage points, and then decide whether to partially repair or completely re-do waterproofing according to the specific situation.

There are two commonly used methods for roof waterproofing, one is to use waterproofing membrane, and the other is to combine waterproof coating and mortar waterproofing agent together, but the latter is the most commonly used.

Because the roof has to be eroded by the sun and rain for a long time, if the mortar waterproofing agent is simply used to do it, it is not flexible, and cracking may occur after long-term sun and rain, so it is necessary to paint a flexible K11 waterproof slurry flexible type first, and then make a protective layer of mortar waterproofing agent, so as to meet the needs of waterproofing.

Generally speaking, if there is a water leak on the roof of a house, it is first necessary to find out the cause of the water leakage and determine the responsible party, which includes the owner, the developer, and the property company.

1. If it is due to water leakage due to the quality of the house, then the developer is required to be responsible for maintenance.

2. If the house has passed the waterproof warranty period (generally waterproof is five years), then the property can apply to the housing management department for housing maintenance. If roof leakage is a common phenomenon and the warranty period of the house waterproofing has passed, then all owners or owners' committees should take the lead in asking professionals to handle the repairs, and the cost should be shared by all owners.

What do you need to pay attention to when waterproofing your roof?

1. Before the roof waterproofing, the base should be cleaned first, and there can be no debris, oil stains, etc., and the waterproof material can be coated only after the base is dry. Moreover, the waterproof coating should be layered during construction, and the upper part of the construction can only be carried out after the lower part is dried.

2. Secondly, when the roof is waterproofed, it can not be carried out in rainy or snowy days, it is best to choose sunny weather construction, and also pay attention to the construction temperature, generally in summer, to ensure that the construction temperature can not be higher than 35 degrees, otherwise the water evaporates too quickly, which will make the coating film crack. In winter, the temperature should be above 5 degrees, and too low a temperature is easy to freeze and damage the coating layer, which will affect the waterproof quality.

3. Finally, when the waterproof coating is used and blended, it must be used according to the operation manual, such as the black and white waterproof coating needs to be used separately and cannot be stirred together to avoid affecting the quality of the material. In addition, the coating film must not be stepped on until it has dried.

4. If there is a large area of water leakage or multiple leakage points on the roof, first check whether there are cracks by professionals, and after dealing with the cracks according to the previous plan, the waterproof membrane is laid on the entire roof, if you want to strengthen the waterproof effect, you can also stare at the branches and pave the heat insulation board, because the height of the heat insulation board is more than 20 cm, it can achieve the dual effect of protecting the waterproof layer and heat insulation. If there is cracks and water seepage on the wall, under normal circumstances, the professional construction team will use hanging baskets and maintenance personnel will work on the outer wall.

Owners who live on the top floor should have encountered roof leakage, once the house leaks water, it will affect the wall and ground, causing a certain loss, which is a very headache. So, how to deal with a roof leak? What should I pay attention to when making a roof waterproof?

Let's find out!

1. How to deal with roof leakage.

1. When the roof leaks, the first time to find the leakage location, but also to see whether the waterproof of the roof is aging, such as the former cover fruit is waterproof material has been blistered, then it means that it is a waterproof material and there is no waterproof effect. Then look at whether the gutter on the roof is blocked, if the gutter is blocked, it will also form roof water seepage.

2. Because some houses, when the roof is built, there may not be waterproof materials, which will lead to roof seepage, so at this time we have to do waterproof construction on the roof, and this construction is also very simple, that is, the roof is coated with asphalt, after the sun is exposed, the coating film made of asphalt is completely dry, and it has a waterproof effect. If the waterproof layer of the roof waterproofing is no longer useful, we have to smash the old waterproof layer, and then re-do a layer of waterproof coating, in the construction of the best professional construction personnel to carry out the construction, so that the waterproof effect has a certain guarantee.

Second, what should be paid attention to when the roof is waterproofed?

1. Environmental requirements for construction.

In order to ensure the quality of construction operation and membrane paving, it is suitable for construction at a temperature of +50C to +350C, and the polymer is changed to asphalt and polymer waterproofing membrane can not be constructed below negative temperature, if it is a hot melt method to pave the membrane, it can be constructed at a temperature of about -100C, because this membrane can withstand low temperatures and will not be easily frozen at negative temperatures. If it is rainy, foggy or humidity, and windy weather, it is not possible to work in the open air, otherwise corresponding technical measures must be taken.

2. Requirements for roof drainage slope.

The drainage slope of the flat roof is 2% to 3%, if the slope is less than or equal to 2%, the material should be used to find the slope. If the slope is greater than 3%, choose to use the structure to find the slope. The longitudinal slope of the roof gutter and the eaves gutter should not be less than one hundredth, the drop at the bottom of the ditch should not exceed 200 mm, and the diameter around the water drop should be 500 mm, and the slope should not be less than five hundredths of a hundredth.

The roof is often exposed, and it is easy to leak when exposed to the wind and sun, so it is very important to make up for the leakage of the roof. And there are many steps to repair the leakage of the roof waterproofing, thenWaterproof roof leakageWhat should I pay attention to in how to construct and repair waterproof leakage? Let's take a look at it together.

How to construct the roof waterproof leakage

First of all, make preparations

Before we can repair the roof leaks, we must first make corresponding preparations. It is necessary to carefully review the drawings of the roof waterproofing project, determine all the structural manufacturing and construction according to the specific situation, and avoid leaving defects and causing later rework.

Ensure the quality of waterproof materials

During construction, it is necessary to check the quality of the waterproof material, carefully see if it has a quality certificate document or quality inspection report, etc., to ensure that it is a qualified product.

Pay attention to the slope of roof drainage

In the construction of the roof, the slope of the roof drainage should be taken into account, and the appropriate slope should be selected according to the material. Generally, the drainage slope of the flat roof is 2% 3%, and the longitudinal slope of the gutter and gutter should not be less than 1%, etc., according to the actual situation.

, in accordance with the order of construction

When we repair waterproofing leaks, we must follow the correct order of construction, such as masonry first, and then installation of equipment and pipes. After these are completed, the construction will be carried out in a first-in-order order.

Pay attention to the seams of the flat layer

Waterproof leakage must pay attention to the seam treatment, which is also a key part of the waterproof project, if it is not done well, there will be water leakage. When waterproof and leakage, the sealing material should be embedded, and the flat layer should not be greater than six meters, and the asphalt mortar should not be greater than four meters.

What should be paid attention to when waterproof and leak repair

1. Before the construction of waterproof leakage, remember to remove the dust, sand and other debris on the surface of the base layer, if there are debris or unevenness on the surface, it will also affect the later construction.

2. When coating the waterproof layer, the dryness of the surface of the base layer must be tested first, the surface drying should be appropriate, neither too wet nor too dry, and then open and check after about 3-4 hours, and the leveling layer covering the part and the waterproof membrane can be constructed without watermark.

3. If it is a large-area coating film construction, it is necessary to do additional reinforcement treatment on the water drop, gutter and other places. The thickness of the waterproof layer of the coating film should also meet the requirements, and there should be no cracks, bubbling and other phenomena.

How to construct, waterproof leakage repair what to pay attention to, I don't know if you understand! The roof waterproof leakage repair construction is very important, we must ask a professional person to help operate, it is recommended that you can also take a look at the above content introduction.
