The video is pretty much self explanatory. Every roof is different so there’s no one size fits all way of getting the rope into position but the actual removal part should be about the same. One thing not included in the video is any mention of safety. Roof avalanche burial deaths can and do happen. Make sure to take all necessary precautions and never attempt this technique or any other roof snow removal without a partner outside the debris area who can dig you out in the case of emergency. Be smart, stay safe.
