According to the analysis of the leakage problem of SMARTROOF METAL ROOF SHEET, the main reason is: ROOF with mineral wool, mineral wool has water absorption effect, when it is cloudy and rainy, the rainwater leakage from the ROOF will all gather in the mineral wool, and the weight will increase. Season roof high temperature, sudden heavy rain, resulting in a sudden drop in temperature, color steel tile rapid shrinkage, resulting in color plate deformation, nails loose.
Why does the rain flow back? Is the backflow water scene unique to SMARTROOF METAL ROOF SHEET? Rather than being specific, the necessary conditions for its composition are:
First: backflow water in the external phase ventilation. There is a difference in air pressure between indoor and outdoor in rainy days, and the low air pressure inside sucks the rain water into it.
Second: the strong wind outside has formed an air channel in the ventilation, and the strong wind has forced the rain into it.
SMARTROOF METAL ROOF SHEET concave and convex across the ROOF wall foot water penetration: use cement wipe eight Angle, sealant or waterproof paint for waterproof maintenance. Cement and metal do not appear to crack. Coating or sealant elongation is small will also appear larger cracks.
The above reasons are the main reasons that directly lead to the leakage of SMARTROOF METAL ROOF SHEET. We are familiar with the above reasons in the construction to try to avoid the occurrence of problems, and we should also find corresponding solutions according to the causes.
