屋頂防水在施工房頂漏水要先找漏，找漏從哪里動手，重要是從房頂的最高處往低處找漏（由于水往低處流）。首先是看房頂有沒有裂紋，原有的屋頂防水層有沒有老化掉，房頂原有的屋頂防水卷材有沒有氣泡，有氣泡的話就證實水現已進入屋頂防水層的底部了，也許就漏水了，還有房頂上的天溝有沒有堵塞。
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.
屋頂防水伸出屋面的管道多。屋面風管和油煙管多，管口周圍選用環氧樹脂和化學泥密封。管道伸出屋面有2.2米高，在風載及氣流沖擊下，管道周圍搖晃，致使環氧樹脂脆裂，化學泥也老化干裂，雨水順著管道流入室內。
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.
屋面選用W型單層瓦，接縫多。屋面接縫密封全部選用硅酮耐侯膠，現屋面因氣流沖擊振蕩發生的振幅及溫度改變發生的漲縮變形值，屋頂防水要大于硅酮耐侯膠的接受值，經不住長時間的揉捏、拉伸，硅酮耐侯膠老化失掉彈性，接縫處賡續地發生開裂最終全部拉開。雨水隨勁風的力量倒灌，形成車間內滲水。
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.
