For architects and roofing contractors, roofs are a source of everlasting concern. Seventy percent of all construction litigation is related to leaks, and every leak is a lost opportunity, representing a cost to repair and a corresponding loss of customer trust. Severe weather seems to be the new normal and the risk of damage from ice dams and wind-driven rain are higher than ever. Underlayments are the last line of defense in a roofing system, and selection of high quality underlayments can be the difference between success and failure.
