1-24-23 Tue 4.5 hrs Back area printing equipment exhaust, They remove the equipment. I installed a 14” cap on the roof to prevent rain from getting into the space. Billy also had me seal a couple potential leaks from the roof in that back room. Use their roof sealant. Bathroom exhaust motor was not running. Found the variable speed control was bad. I ordered a new variable speed control from interstate electric Should be in in a couple days
