1、工程施工是形成工程質量的關鍵因素。即使有合格的金屬屋面防水涂料，優秀的屋面防水設計，但不執行施工規范、標準，施工質量低，仍會使金屬屋面防水發生滲漏。因此，確保施工質量是提高建筑屋面防水質量的關鍵。造成施工質量低劣的主要原因是缺乏金屬屋面防水專業施工隊伍，有的施工單位甚至使用絲毫不懂金屬屋面防水技術的工人去進行金屬屋面防水施工操作，其后果必然導致防水工程的失敗。對金屬屋面防水施工工序的質量控制及管理不重視。金屬屋面防水施工期間，尤其是施工人員多，施工工種多，并且基本上為交叉或平行作業，沒有對已完防水屋面采取有效保護措施，造成對已做好的防水層的破壞。
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、使用維護方面的問題。工程竣工交付使用后，必須做好金屬屋面工程的使用維護工作，這對確保防水的使用年限很重要。因使用維護不善而造成金屬屋面滲漏的原因主要有無專人對金屬屋面進行定期檢查，對一些局部出現的缺陷未及時進行處理，天長日久導致缺陷擴大、裂縫發展、節點破壞，屋面滲漏。金屬屋面無人定期清掃，疏通天溝、檐溝和排水口。落水管堵塞，屋面長期積水，使防水層脫層、腐爛。有的屋面因長期不清掃，植物滋生，植物的根莖扎入防水層中，而使防水層遭到破壞。在金屬屋面防水層上施工操作，鑿眼打洞，使防水層局部受到破壞，卻又未能及時修補。
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.
