1、高聚物改性沥青防水卷材以及胶结材料的种类、牌号及合比，都一定要符合设计要求以及有关的技术规范还有标准规范。
1. The type, brand and ratio of polymer modified asphalt waterproof coiled material and cementitious material must meet the design requirements, relevant technical specifications and standard specifications.
2、卷材防水层及其变形缝，檐口、泛水、水落口、预埋件等处的细部做法，必须符合设计要求和屋面工程技术规范的规定。3、屋面卷材防水层严禁有渗漏现象。
2. The details of coiled material waterproof layer and its deformation joint, cornice, flashing, water drop, embedded parts, etc. must meet the design requirements and the provisions of roof engineering technical specifications. 3. Leakage of waterproof layer of roof coiled material is strictly prohibited.
4、铺贴卷材防水层的基层应符合排水要求，平整洁净，无起砂、空鼓和松动现象，阴阳角处应呈圆弧形，防水层无积水现象。
4. The base course of the coiled material waterproof layer shall meet the drainage requirements, be flat and clean, without sand, hollowing and loosening, and the internal and external corners shall be circular arc, and the waterproof layer shall be free of ponding.
5、胶结层应涂刷均匀，不得有漏刷和麻点等缺陷。
5. The cemented layer shall be brushed evenly without defects such as missing brushing and pitting.
6、卷材防水层铺贴和搭接、收头，应符合设计要求和屋面工程技术规范的规定，且应粘结牢固，无空裂、损伤、滑移、翘边、起泡、褶皱等质量缺陷。
6. The paving, lapping and ending of coiled material waterproof layer shall meet the design requirements and the provisions of roof engineering technical specifications, and shall be firmly bonded without quality defects such as void crack, damage, slip, edge warping, blistering and fold.
7、应注意的质量问题：1卷材防水层空鼓：多发生在找平层与卷材之间，尤其是卷材的接缝处;原因是基层不干燥，气体排除不彻底，卷材粘结不牢，压得不实;应控制好各工序的验收。2防水层渗漏：加强细部操作，管根、落水管口、伸缩缝和卷材搭接处，应做好收头粘结，施工中保护好接槎，嵌缝时应清理干净，使干净的接槎面相粘，以保证施工质量。3积水：屋面、檐沟泛水坡度做的不顺，坡度不够，屋面平整度差;施工时基层找平层、泛水坡度等应符合要求。
7. Quality problems needing attention: 1. Hollowing of coiled material waterproof layer: it mostly occurs between leveling layer and coiled material, especially at the joint of coiled material; The reason is that the base course is not dry, the gas is not completely discharged, the coiled material is not firmly bonded and the pressure is not solid; The acceptance of each process shall be well controlled. 2. Leakage of waterproof layer: strengthen the detailed operation. The pipe root, outlet, expansion joint and lap joint of coiled material shall be well bonded, and the joint shall be protected during construction. When caulking, it shall be cleaned to make the clean joint surface stick to ensure the construction quality. 3 ponding: the flashing slope of roof and eaves gutter is not smooth, the slope is not enough, and the roof flatness is poor; During construction, the base leveling layer and flashing slope shall meet the requirements.
<strong>屋顶防水验收方法：验收顺序：基层表面清理、修补→涂刷基层处理剂→铺设节点附加层→试铺→铺贴卷材→收头处理、节点密封→清理、检查、修整→蓄水?
