屋顶防水在施工房顶漏水要先找漏，找漏从哪里动手，重要是从房顶的最高处往低处找漏（由于水往低处流）。首先是看房顶有没有裂纹，原有的屋顶防水层有没有老化掉，房顶原有的屋顶防水卷材有没有气泡，有气泡的话就证实水现已进入屋顶防水层的底部了，也许就漏水了，还有房顶上的天沟有没有堵塞。
Waterproof in construction for the leak in the roof to find leakage, for leakage from where to start, mainly from the height of the roof to the lowest level for leakage (because the water flows downwards), the first is the top of the house there is no crack, original waterproof layer has no aging off, roof of the original waterproofing membrane bubbles, bubbles that water has now entered the waterproof layer of the bottom, thus leaking, and the roof gutter has not clogged.
屋顶防水伸出屋面的管道多。屋面风管和油烟管多，管口周围选用环氧树脂和化学泥密封。管道伸出屋面有2.2米高，在风载及气流冲击下，管道周围摇晃，致使环氧树脂脆裂，化学泥也老化干裂，雨水顺着管道流入室内。
Waterproof and extend the roof of the pipe. The roof wind tube and the fume pipe, pipe around the epoxy resin and chemical mud seal. Pipe extends out of the roof 2.2 meters high, the wind load and under the impact of air flow, shaking around the pipeline, resulting in brittle epoxy resin, chemical sludge aging dry, rain along the pipeline into the interior.
屋面选用W型单层瓦，接缝多。屋面接缝密封全部选用硅酮耐侯胶，现屋面因气流冲击振荡发生的振幅及温度改变发生的涨缩变形值，屋顶防水要大于硅酮耐侯胶的接受值，经不住长时间的揉捏、拉伸，硅酮耐侯胶老化失掉弹性，接缝处赓续地发生开裂最终全部拉开。雨水随劲风的力量倒灌，形成车间内渗水。
Roof selection of W type single tile, seams. Roof joint sealing fully use silicone weather resistant glue, now roof because of air impulse oscillation amplitude and temperature change of collapsible deformation value, Zibo waterproof than silicone in resistant glue Hou accepted value, through don't live for a long time of kneading, stretching, silicone weatherproof rubber aging lose elasticity, seams continue to occur eventually dehiscent fully opened. The rain with wind power flow, formation of water seepage in the workshop.
