When wrinkles are caused by installation techniques, simply doing repair on membranes is all that is required. However, more extensive measures such as mechanical fastening of the entire roofing system or complete reconstruction should be considered when wrinkles are caused by the instability of components under the membranes. Areas needing repairs (e.g.: excessive wrinkles, blisters, membrane detachment and infiltrations at overlaps) must be corrected prior to the installation of the resurfacing membrane, according to the methods described below.
