Find the solution to the water leakage problem of color steel tile roof. What should I do if the color steel tile leaks? Chengdu Shu Yu Waterproof will help you.

1. The main reason for the water leakage of color steel tile roof:

1. Water seepage at the foot of high-low span roof wall: cement plastering, sealant or waterproof coating shall be used for waterproof protection. When cement is not combined with metal, cracks will occur. When the elongation of paint or sealant is small, large cracks may appear.

2. Why does the weather-resistant sealant still seep out? The weather-resistant sealant will shrink after curing, and it may separate between the sealant and the frame when shrinking, which will be more serious if there is dust on the frame. The long-term high temperature of color steel roof accelerates the aging of weather-resistant adhesive, and the metal material expands with heat and contracts with cold for many times, and the weather-resistant adhesive soon fails.

3. Why did the waterproof paint 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. Coupled with roof vibration, the coating elongation is low and cracks appear. Jerry-building in the construction of waterproof coating, the coating thickness is too thin, and it will soon age and crack.

4. Why does the rain flow backwards? The phenomenon of backward flow is a unique phenomenon of color steel tile roof, and the necessary conditions for its formation are: backward flow and internal and external ventilation. First: there is a pressure difference between indoor and outdoor in rainy days, and the low pressure inside sucks rainwater in. Second: the strong wind outside formed an air duct in the ventilated place, and the strong wind forced the rain to blow in.

5. The negligence in production, transportation and construction caused the deformation of color steel tile. The quality of color steel tile is poor, and the deformation of color steel tile is caused by master's roof construction.

6, wind, rain and other external forces, resulting in color steel tile roof vibration for a long time, so that the nail hole and iron joint wear for a long time, rust in the rain, and then wear and rust, more and more serious.

7. Why does the self-tapping nail have a rubber pad or leak water? First: the self-tapping nail was too hard during construction, and the rubber pad was damaged. Second: the rubber pad ages quickly and loses its waterproof effect soon.

8. The main reasons for the deformation of the color steel tile roof are as follows: First, the roof has a long span, water accumulates in the middle for a long time, and the gravity in the middle increases. The more times it rains, the more serious the deformation, and even the roof collapses. Secondly, the roof with mineral wool has the function of absorbing water. On rainy days, all the rainwater leaked from the roof gathers in mineral wool, which increases the weight. Third, when the roof is hot in summer, the sudden rainstorm makes the temperature of the color steel tile drop sharply, and the color steel tile shrinks rapidly, resulting in the deformation of the color plate and the loosening of the nails.

Disadvantages: long construction time and high project cost.

Two. Waterproof method of color steel tile;

It is especially effective to cover the leakage of color steel tile roof with SBS modified asphalt waterproofing membrane. After the roof is covered with a layer of SBS modified asphalt waterproofing membrane, all the joints of the color steel tile have been covered, and there is basically no gap and no water leakage. Moreover, it is fully paved, and it will not crack the waterproof layer because of the thermal expansion and cold contraction of the color steel tile, just like the seam of the color steel tile. Moreover, after the color steel tile is completely covered, the service life of color steel tile is greatly prolonged. If the color steel tile is directly exposed to the air for a long time, the metal inside the color steel tile will soon rust, and the color steel tile will be replaced in a few years, resulting in higher cost.
