1、工程施工是形成工程质量的关键因素。即使有合格的金属屋面防水涂料，优秀的屋面防水设计，但不执行施工规范、标准，施工质量低，仍会使金属屋面防水发生渗漏。因此，确保施工质量是提高建筑屋面防水质量的关键。造成施工质量低劣的主要原因是缺乏金属屋面防水专业施工队伍，有的施工单位甚至使用丝毫不懂金属屋面防水技术的工人去进行金属屋面防水施工操作，其后果必然导致防水工程的失败。对金属屋面防水施工工序的质量控制及管理不重视。金属屋面防水施工期间，尤其是施工人员多，施工工种多，并且基本上为交叉或平行作业，没有对已完防水屋面采取有效保护措施，造成对已做好的防水层的破坏。
Construction is a key factor in the formation of project quality. Even if there is a qualified metal roof waterproof coating, outstanding roofing design, but does not perform construction norms,standards, low quality of construction, metal roof will remain waterproof leakage occurs. Therefore, to ensure the construction quality is the key to improving the quality of roofing construction.The main cause of poor quality of construction is the lack of a metal roof waterproofing professional construction team, and some construction units did not understand even use metal roofing waterproofing technology workers to carry out the metal roof waterproof construction operations, the consequences will inevitably lead to failure of water works. Metal roof waterproof construction process quality control and management is not valued. During the metal roof waterproof construction, especially construction workers and more and more construction jobs, and substantially cross or parallel operations, failed to take effective measures to protect the waterproof roof has been completed, resulting in damage to the waterproof layer is ready.
2、使用维护方面的问题。工程竣工交付使用后，必须做好金属屋面工程的使用维护工作，这对确保防水的使用年限很重要。因使用维护不善而造成金属屋面渗漏的原因主要有无专人对金属屋面进行定期检查，对一些局部出现的缺陷未及时进行处理，天长日久导致缺陷扩大、裂缝发展、节点破坏，屋面渗漏。金属屋面无人定期清扫，疏通天沟、檐沟和排水口。落水管堵塞，屋面长期积水，使防水层脱层、腐烂。有的屋面因长期不清扫，植物滋生，植物的根茎扎入防水层中，而使防水层遭到破坏。在金属屋面防水层上施工操作，凿眼打洞，使防水层局部受到破坏，却又未能及时修补。
Use of maintenance. Upon completion of delivery, must be prepared to use metal roofing maintenance engineering, which ensure water service life is very important. The reason for using poor maintenance caused by leakage of the major presence of metal roofing metal roofing specialist for regular checks on some local defect appears not timely processed, Over cause defects to expand,crack development, node damage, roof leaks. No regular cleaning of metal roofing, gutters clear, gutters and drains. Clogged downspouts, roof long-term water, the waterproof layer delamination,
rot. Some of the roof due to long periods of cleaning, plant breeding, plant roots plunge into the water layer, leaving destruction waterproof layer. Waterproof layer on the metal roof construction operations, cutting eye holes, partial damage to the waterproof layer, but failed to repair.
