| Abstract | Moisture traps in roof systems should be avoided. Where a double membrane system is to be provided this can be accomplished by designing a vented system. Breather vents can relieve vapour pressure and provide for drying of small quantities of moisture over a relatively long period of time. They tend to be unsuccessful in drying wet roofs unless wetting can be eliminated at the source and the venting system designed to facilitate drying. Venting can be achieved without stack vents [see CBD-99] or systems can be used that do not need vents [see CBD-150]. |
