How many years can a roof be waterproofed?

If the roof of the building uses general modified asphalt waterproofing membrane, the service life is up to 5 years, and the service life can be increased to 10 years by making a layer of concrete protective mortar on the surface. If the roof is used polyurethane waterproof coating, the service life is about 20 years, polyurethane is a new type of coating waterproof material, the weather resistance is very good, so the service life of the roof waterproof layer mainly depends on what type of waterproof material is used.

The warranty period of roof waterproofing is 5 years, and the roof waterproofing project must meet the environmental requirements, and it is strictly forbidden to carry out construction in bad weather such as rain, snow or level 5 or above.

The structural form of a flat roof is as follows:

1. Multi-storey residential buildings:

It is characterized by large quantity and low cost, and is generally a 5-7 layer brick-concrete structure.

2. High-rise buildings:

The characteristics are mainly frames and cylinders, which are suitable for residential, office buildings and commercial facilities.

3. Industrial plants:

It has a large span and large deformation, and is dominated by a single-layer industrial frame and a row frame structure.

4. Large public buildings:

Features of large span and large space, suitable for railway stations, memorial halls, etc.

The roof waterproofing treatment method is as follows:

1. Investigate the condition of the original roof

Including whether the roof structure is reasonable, whether the old waterproof layer is damaged, whether the roof base is cracked, whether the roof panel is misplaced, whether there is leakage in the skylight, chimney, downspout, etc.

2. Comprehensive analysis of leakage

Determine the construction environment, construction methods, repair scope, waterproof materials, base reinforcement methods and the cost of leakage water treatment, and pay attention to fire protection measures.

The roof waterproofing project generally has a five-year warranty period, which is calculated from the date of completion and acceptance of the work. If the roof of the house purchased within the waterproof warranty period leaks, the owner can contact the developer to repair it for free and compensate for the loss. Waterproofing in engineering mainly refers to the prevention of open water and visible running water.

A small amount is waterproof to protect the building from water vapor and moisture. The main materials in this area are coils, polyurethanes, etc. The construction requirements are high and the process is complex.

Home improvement waterproofing refers to the general term of waterproof knowledge, waterproof materials and waterproof technology related to family life. This includes, but is not limited to, waterproofing of roofs, toilets, balconies, facades, kitchens, basements, and swimming pools. This subdivision is taking shape, the construction requirements are relatively low, and it is universal and practical.

Article 39 of the Regulations on the Quality Management of Construction Projects: The quality warranty system shall be implemented for construction projects. When the construction project contractor submits the project completion acceptance report to the construction unit, it shall issue a quality warranty certificate to the construction unit.

Article 40 of the warranty scope, warranty period and warranty responsibility of the construction project shall be clarified in the quality warranty certificate: under normal use conditions, the minimum warranty period of the construction project is (1) infrastructure engineering, foundation engineering and main structure engineering of housing construction, and the reasonable service life of the project specified in the design documents (2) the leakage prevention of roof waterproof engineering, toilets, rooms and external walls with waterproof requirements, which is 5 years; (3) Heating and cooling system, for 2 heating periods and cooling periods: (4) Electrical pipelines, water supply and drainage pipelines, equipment installation and decoration projects, for 2 years.

If the roof is waterproofed well, it can remain unchanged for 70 years, and there are many houses that do not need to be waterproofed during the 70-year property right period, and if it is done poorly, there may be an accident in half a year.

Generally, the validity period of the first-level waterproof design of the roof is 15 years, but it is not guaranteed that the waterproof will not be damaged or damaged after 15 years, and the leakage is not guaranteed to be used after 15 years, which is just a theoretical statement, because the waterproofing and use process on the roof, the maintenance process and maintenance are all related to each other, if the construction is done well, the period of use may be longer.

If the waterproof coating is of good quality and is done with more care, it can generally last for 8 to 10 years, but if the waterproof coating is too thin, it may encounter heavy rain, and it will still leak after a long period of continuous rain.

Generally, our roof waterproofing is maintained for more than 5 years, and some places begin to seep water in 5 years, so it must be re-waterproofed.

The waterproof shelf life of the general point may be four or five years, that is to say, under normal circumstances, it will not be damaged before this year, and the good and expensive waterproof materials should be thicker, which can be about 10 years, but also depends on the master's construction technology and base material, as well as environmental factors, the waterproof in my home is waterproof, and it has been more than eight years this year, and there is no problem, it should be considered better.

According to the construction practice and process, a simple 3-5 years to do the protective layer can be 5-8 years.

Roof waterproofing can generally be maintained for 5 years, this standard is the country's minimum requirement for waterproof quality, of course, waterproof manufacturers will definitely advertise for a longer time!

Generally, the waterproof shelf life is five years, that is to say, under normal circumstances, the waterproof layer can be used for at least 5 years without damage, and the waterproof material is thicker, which may take more years, about 10 years, so the general roof waterproof is calculated according to the material. The service life of polyurethane waterproof coating will be longer, but it should also be weather-resistant, and it should be okay for more than ten years.

It depends on which grade of material you use to make waterproofing, if it is of high quality, it can be 5 to 10 years. If it is a general or defective product, it will be a problem in a year.

Article 40 of the Regulations on the Quality Management of Construction Projects stipulates: "Under normal use conditions, the minimum warranty period for construction projects is:

A) infrastructure engineering, housing construction foundation engineering and main structure engineering, for the design documents specified in the reasonable service life of the project;

2) Roof waterproofing works, toilets with waterproof requirements, rooms and external walls for leakage prevention, for 5 years;

3) Heating and cooling system, for 2 heating periods and cooling periods;

4) Electrical pipelines, water supply and drainage pipelines, equipment installation and decoration projects, for 2 years.

The warranty period for other items shall be agreed between the employer and the contractor.

The warranty period of the construction project shall be calculated from the date of acceptance of the completion of the project.

Ten years or so, if you don't do well, you can only manage three or five years ,...

You mentioned that this problem makes people can't, there are too many reasons for the leakage of the house, and it is a lie to say how many years it can be maintained, irresponsible statement, whether the waterproof is done well or not directly affects the waterproof effect, and it may be able to be used for thirty or fifty years if it is done well, and it may leak when it is not done well.

There is no complete standard for this, and the waterproofing of the general sewage roof depends on what kind of waterproof and waterproof he does, and whether he does it well or not? The general warranty is one year.

Generally speaking, about ten years.

Generally, the developer has a shelf life of 5 years (there are also different ones), and then it goes back to the property! The use of the property is paid according to the contract.

This is related to the method of doing waterproofing, according to the material research and development, it is generally no problem for 20 years.

Generally, the waterproof shelf life of the point is five years, that is to say, goodbye, under normal circumstances, the waterproof layer can be used for at least 5 years without damage, and the waterproof material is a little more expensive, and the waterproof material is also thicker, which may have to be more than 10 years, so the general roof waterproof ** is calculated according to the material.

Roof waterproofing generally lasts for five years, and if your material is good, it can be kept for another five years.

1. Clean up the base layer: clean up the dust and debris on the surface of the base layer that has passed the acceptance before construction.

2. Additional layer construction: use the hot melt modified asphalt membrane to make an additional layer in the details of the parapet wall, water drop, pipe root, cornice, yin and yang corner before the construction of the waterproof layer.

3. Material transportation: materials are transported to the construction site and transported to the roof construction by crane.

4. Paving coil: a. The thickness of the coil meets the design requirements. When the asphalt waterproofing roll is cut to the corresponding size, the junction of the base layer and the membrane is heated with a flame spray gun with the unwinding of the roll, and the membrane is evenly heated back and forth, and the membrane is rolled forward and pasted while the material surface of the membrane has just melted.

B, the membrane parallel ridge from the cornice to the top of the paving, two-way water slope membrane lap should be along the direction of the water shore to send back to the Mulberry Yong Rock Take. c. The coil starts from the downhill slope of the flowing water, pops up the baseline and paves it according to the specifications of the coil, and makes the long side of the coil perpendicular to the slope of the flowing water. d. The coil connected to the paving plane and the façade should be carried out from bottom to top.

5. Hot melt edge sealing: heat the lap joint of the coil with a spray gun, make the two bond firmly while it is hot, extrude the asphalt at the edge as the degree, and fill the end with sealing paste tightly.

6. Brush the waterproof paint for the first time. Before construction, ensure that the construction site is clean and dry, and the waterproof coating should be coated with no omissions, firmly combined with the base layer, no cracks, no bubbles, and the thickness of the toad should meet the requirements of the product.

7. Brush the waterproof paint for the second time. Note the first.

First, the second waterproof coating needs to have a certain time interval, and the second time can only be carried out after the first coating is dry, and the specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced.

8. Lay a protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

9. Closed water test. During the closed water test, the 5 widows should not be less than 2 cm, and they should be stored for at least 24 hours to observe that there is no leakage. If there is a leakage, you can't be negligent.

There is still a difference between waterproofing the roof and repairing leaks in the roof, one should be done as a whole, and the other can be repaired locally.

There are several ways to do waterproofing on the roof, the guerrilla practice is generally to directly pave the membrane or asphalt, and the validity period should be about 3 years if the construction is strictly in accordance with the construction specifications, but the guerrillas generally do not have a warranty, even if you give you a verbal or written warranty, it is useless, basically you can't find it after one or two months, or try to find a professional waterproof company to do a good job.

Each company's construction plan and process are also different. But there are three general standard schemes:

1. Ensure that there is no floating ash on the face, lay a waterproof membrane, and make a water-blocking stem on non-public roofs, which is low, valid for about 3-5 years, and has a 1-year warranty.

2. Three waterproofs on the face, non-public roofing as a water-blocking stem, **medium, can increase the protective layer, valid for about 15 years, 5 years warranty.

3. Manually break to the floor layer, repair the base layer, restore the additional layer of the roof and do waterproofing, ** high, valid for about 30 years, 5 years warranty.

This is a standard solution, and in fact each company will tailor the solution to the situation on site. In addition, don't listen to any 10-year warranty, 20-year warranty and the like, these are slogans and have no effect. The state stipulates that the warranty period for housing construction projects is 5 years.

As for the partial leakage of the roof, it will be relatively simple, slight leakage can be repaired according to the site situation, small area leakage can be partially grooved to do waterproofing, large area leakage indicates that the overall waterproof failure, it is recommended to do the overall waterproofing.

The choice of the company is also exquisite, the qualification company basically belongs to the construction engineering waterproof company, and the current home waterproof maintenance company is not qualified. In addition, 80% of the companies belong to outsourcing companies, which undertake projects individually, outsource to casual workers, or directly find casual workers for construction. Therefore, when choosing a company, we should pay attention to the time when the company was established, whether it is a direct master, what is the service standard, the service process and the warranty time.

Like we are the first free door-to-door survey, according to the site out of the plan and the first contract sent to the customer, the customer feels that our plan is professional and reasonable, recognize us and then cooperate, before signing the contract. We do not force, we are not afraid of comparison, we only provide customers with more choices, and we only hope to impress customers with our professional services.

Now the new roof waterproofing material has a shelf life of more than 50 years.

If you do it well, you will have no problem keeping it for 20 years.

Roof waterproofing can generally be maintained for five years, and if the material is good, it is okay to keep it for another five years.

Generally, the waterproof shelf life of the point is five years, that is to say, goodbye, under normal circumstances, the waterproof layer can be used for at least 5 years without damage, and the waterproof material is a little more expensive, and the waterproof material is also thicker, which may have to be more than 10 years, so the general roof waterproof ** is calculated according to the material.

The roof is the envelope and load-bearing structure that covers the uppermost layer of the house, and one of its main functions is to "shelter from the wind and rain". According to the different drainage slopes, roofs can be divided into flat roofs and sloped roofs. Generally, the slope of flat roofs is less than 10%, the most commonly used slope is 2 3%, and the slope of sloping roofs is more than 10%.

Generally, the waterproof shelf life of the point is five years, that is to say, goodbye, under normal circumstances, the waterproof layer can be used for at least 5 years without damage, and the waterproof material is a little more expensive, and the waterproof material is also thicker, which may have to be more than 10 years, so the general roof waterproof ** is calculated according to the material.
