A hand tool for locating and measuring the location of inaccessible rafters and studs from the outside of a roof or wall. The tool has a base plate and a tubular guide fixedly mounted at an angle to the base plate. A measuring rod appropriately marked with measurement indicia is a sliding fit into the bore of the guide. The tool is used by drilling a hole through the roof or wall, using the tubular guide as a drill guide, and then inserting the measuring rod into the guide and moving it until the tip of the rod encounters the side of a rafter or stud. After noting the measurement indicated on the rod, the rod and base plate are removed. The noted measurement will be the distance from the center line of the drilled hole to the centerline of the rafter or stud.
