Using the RE1 rafter center locator

Exposed rafters: A rooftop installation headache

Installers of solar, electrical and other rooftop equipment generally have two choices when working over exposed rafters: make multiple measurements below, transfer them to the roof and hope their lag screws stay inside the rafters, or drill visible reference holes right through the roof, leaving a cosmetic mess and a potential leak.

No more compounding of errors by transferring multiple measurements in the vain hope of accuracy. No more lag screw blowouts or visible holes after measurement transfers fail. RafterEye gives a sight-line from the rooftop direct to rafter center.
