Steel roof leakage is a common phenomenon, why this problem must find the root cause leaks, then what position steel roof leaks it easy? The role of a wind, rain and other external forces, resulting in prolonged quiver color steel tile roof, making nail holes and worn metal seams Director at the time, encountered rain on rust. Then again wear again rust, more to the more serious. 2, with the weather sealant why would seepage? Weather sealant must be shrinkage during solidification, contraction may cause separation between the plastic and the frame, if the frame there is dust, this situation will get worse. Color temperature accelerated weathering roofing glue long aging, repeated expansion and contraction of the metal material, weathering plastic quickly lose effectiveness. 3, color steel tile roof deformation of the main reasons: First: roof span, resulting in the middle of the water a long time, the central gravity increased, the more the number of deformed more serious rain, and even the collapse of the top two: with mineral wool The roof, mineral wool absorbent effect has encountered rainy days, the roof leaks rain all gathered in mineral wool, the weight increase. 4. Why is the rain will be back? Pour water phenomenon is a phenomenon unique color steel tile roof, a necessary condition for its formation are: pour water in the Foreign Office ventilation. First: the rain has indoor and outdoor air pressure difference, low pressure inside the rain sucked. Second: The winds have already ventilated place outside to form a duct, rain and strong winds blowing into it forcibly. 5, waterproof coatings why would two years after repair leaking? Waterproof coating can cause uneven flow coating thickness of the construction, there is a gap can not easily be found on the roof plus low elongation fibrillation, paint cracks. Waterproof coating to cut corners during construction, coating thickness is too thin, quickly aging cracking. 6, the level of cross-roof flush foundation seepage parts: the use of cement plaster character angle, sealant or waterproof coating waterproof protection. Cement and metal does not bind cracks. Paint or sealant elongation of small cracks will appear larger. 7, the production and transportation process, the construction process of deformation caused by careless steel tile. Poor quality steel tile, steel tile Master roof deformation caused by construction. If Seoul good waterproofing professional waterproof construction technology, with commitment to waterproof all types of industrial, civil and bridge construction, sealing, grouting reinforcement, decorative, corrosion, insulation and construction and installation capacity.
