House leakage is a common problem in rainy season. Although the progress of modern construction technology has greatly alleviated the leakage of houses, for temporary houses like Jinan color steel plate houses, the leakage phenomenon is relatively serious. So what are the main causes of this phenomenon? Let's take a look at it.

1、在生产和运输过程中，不慎造成彩钢瓦变形。色板质量差，并且色板由于屋顶结构而变形。

1. In the process of production and transportation, the color steel tile is deformed. The quality of the color board is poor, and the color board is deformed due to the roof structure.

2、风雨等外力导致彩钢瓦屋面长期振动，造成钉孔和铁皮接头长期磨损，下雨时生锈。然后又磨损生锈，越来越严重。

2. Wind and rain and other external forces lead to long-term vibration of colored steel tile roof, which causes long-term wear of nail holes and iron sheet joints, and rust in rain. And then wear and rust, more and more serious.

3、带橡胶垫的自攻钉为什么还会渗水?，橡胶垫在施工过程中被自攻钉破坏。其次，橡胶垫老化很快，很快就会失去防水效果。

3. Why do self tapping screws with rubber pads still seep? First, rubber pads are damaged by self tapping screws in the construction process. Second, the rubber pad aging quickly, will soon lose the waterproof effect.

4、济南彩钢板屋面变形的主要原因是：屋面跨度大，中间积水，重力加大。雨越下越大，变形越严重，甚屋顶坍塌。矿棉屋顶具有吸水功能。在雨天，所有从屋顶泄漏的雨水都聚集在矿棉里，这增加了重量。当夏季的屋顶很热时，大雨突然降临，导致彩板温度骤降，彩板迅速收缩，导致彩板变形，钉子松动。

4. The main reasons for the deformation of Jinan color steel plate roof are: large roof span, water accumulation in the middle, and increased gravity. The more rain, the more serious the deformation, even roof collapse. Mineral wool roof has water absorption function. On rainy days, all the rainwater leaking from the roof is gathered in mineral wool, which adds weight. When the roof is very hot in summer, the heavy rain suddenly comes, which leads to the sudden drop of color plate temperature and the rapid contraction of color plate, resulting in deformation of color plate and loosening of nails.

5、高低跨屋面墙脚渗水：用水泥抹八字角，用密封胶或防水涂料进行防水保护。当水泥不与金属结合时，就会出现裂缝。涂层或密封剂的小伸长也会导致大裂缝。

5. Water seepage at the foot of high and low span roof: use cement to wipe the splayed angle, and use sealant or waterproof coating for waterproof protection. Cracks occur when cement does not bind to metal. Small elongation of the coating or sealant can also cause large cracks.

6、为什么防水密封胶仍然会导致渗水?耐候密封胶固化时需要收缩，这可能会导致密封胶和框架分离。如果框架有灰尘，这种情况会更严重。彩钢屋面的长期高温加速了耐候胶的老化。这种金属材料受热膨胀，遇冷收缩多次，这种耐候粘合剂很快就失效了。

6. Why does the waterproof sealant still cause water seepage? The weather resistant sealant needs to shrink during curing, which may lead to the separation of sealant and frame. If there is dust in the frame, this situation will be more serious. The long-term high temperature of color steel roof accelerates the aging of weather resistant adhesive. This kind of metal material expands when heated and shrinks many times when it is cold, and the weather resistant adhesive will soon fail.

7、防水涂料修补两年后为什么会渗漏?防水涂料的流动性导致施工时涂层厚度不均匀，不易发现裂缝。此外，屋顶振动导致涂层伸长率低和裂缝。在防水涂料的施工过程中，工作被缩短，涂层的厚度太薄，涂层很快老化和开裂。

7. Why does the waterproof coating leak after two years of repair? The fluidity of waterproof coating leads to uneven coating thickness during construction, and it is not easy to find cracks. In addition, roof vibration causes low elongation and cracks in the coating. In the construction process of waterproof coating, the work is shortened, the thickness of coating is too thin, and the coating is aging and cracking quickly.
