A measuring tape tip body is described for attachment to a standard semi-rigid automatic-retrieval tape measure. The tape tip body allows the dimensions of a roof to be accurately determined by advancing the semi-rigid tape and tape tip body from the eave to the ridge of the roof without substantial interference due to roof shingles or tiles. This method and device allows steep, dangerous or unclimbable roofs to be measured safely and economically from the eave of the roof.
