Upon arrival customer needs 5 roof drains moved 12” from existing hole to have proper spacing for flashing of roof. We gathered pictures and customer wants to provide access for us to install offset. Customer states we can not gain access from underneath roof. We will have estimate provided tomorrow morning. Customer would like pictures of drain we will be installing. Total of 5 roof drains that need to be offset 12”. Thank you for calling John The Plumber -Shane
