Holy odorous defecation. We have hail - in the spring and again in the fall. Big hail here is the size of fresh green peas that you hand shell. My house was designed to have three skylights - I nixed that idea right off. I could see my tired old body trying to keep the glass in the skylight clean and every one I've ever seen will eventually leak. New house down the road with nice big skylight & its screened and it levers open and its got nice big water stains on the sheetrock all the way around it. It looks so really great there on the celling in the living room. I was really impressed, NOT.
You know - something over the top of the skylight will defeat its purpose and if its strong enough to stop hail as big as golf balls......... from inside the house it will look like you are in a prison cell. A scene right of Dante's Inferno.
