Abstract
Steep-sloped roofs are chosen for many reasons. Most homes in the U.S. have steep-slope roofs, primarily for their exterior aesthetic appeal. Churches and other auditoriums most often have steep-sloped roofs. Steep-sloped roofs in general have a reputation of providing superior weather resistance. There are many factors in the design of steep-slope roofs. Having the right tools can help ease the design process. Among the design issues are ice damming and the opposite, excessive high temperature. Ventilation is an approach that is used to alleviate these issues, and the research has provided guides on how to appropriately use ventilation. Consultants may be knowledgeable of the research, but the issue is finding the time and tools to apply this knowledge. The use of the new tools to determine if ventilation is adequate will be demonstrated. The scientific background for the tools is discussed, and suggestions on how the information is to be applied are provided.
