畜水试验屋面施工完成以后,许多业主都希望在验收之前能证实一下屋面系统的整体性能。有些设计人员和咨询师要求屋面进行蓄水试验,作为确认屋面施工没有问题的一种手段。加拿大屋面工程协会技术委员会不支持这种做法,认为蓄水试验不是可靠的保证质量的方法,与试验有关的风险远大于任何可能的获益。他们认为,蓄水试验并不能提供屋面设计和施工质量的有用信息,也不能提供关于所用材料耐久性的信息。如果水深足够的话,该试验可能表明卷材是否存在裂口,但并不能反映屋面全面的功能,如抗风、抗冲击、抗温度应力等。
After the completion of the livestock water test roofing, many owners hope to confirm the overall performance of the roofing system prior to acceptance. Some designers and consultants require roofing for water storage tests as a means of confirming that there is no problem with roofing. The Canadian Society of Roofing Technical Committee did not support this practice, arguing that the water storage test was not a reliable method of guaranteeing quality and that the risk associated with the test was far greater than any possible benefit. They believe that the water storage test does not provide useful information on roof design and construction quality nor does it provide information on the durability of the materials used. If the water depth is sufficient, the test may indicate whether there is a gap in the web, but does not reflect the full roof features such as wind, impact, temperature stress and so on.
