For our northern customers that have heavy snow, there is a slot in the head that allows the unit to breath when the top is covered. So there will be no snow plugging unless the entire roof is covered with about a foot of snow.
"Yesterday we finally got some warm weather combined with the availability of our roofer! He removed the ss mesh and installed the Critter Quitters® without any problems. He advised we still had plenty (1-2") of good integrity lead flashing around the bottom of the vents.
I sincerely thank you for all your assistance and patience with my numerous questions and concerns.
One side comment to share: Way back when I originally explained the Critter Quitters® to him by phone plus sending him your brochure, the roofer indicated he was totally unfamiliar with them and kept promoting neoprene. Yesterday when he actually saw the Critter Quitters® he exclaimed "oh, I've seen and installed these before - they're great.
Thanks again and I will try to spread the Critter Quitter® word to our circle of friends and neighbors. Best of health and success with your business."
