ABSTRACT:
A tape measure for use with roof framing members is disclosed, the tape measure having a true distance scale having true distance indicia indicating feet, inches and fractions of inches, and one or more secondary false distance scales having false distance indicia corresponding to the true distance indicia, where the actual distances between false distance indicia is the true distance between the true distance indicia multiplied by a predetermined pitch factor. The false distance indicia allow direct marking of the proper rafter lengths for common, hip, valley and jack rafters for a given pitch roof after measurement of the run distance using the true distance scale, without need of calculation or of knowledge of the actual rafter length.
