Kenton;

Don't you know that these glycol filled exterior sprinkler heads are to protect this roof of fiberglass imitation slate from the ambers from the Winter wood burning stoves up in Wisconsin??

Gee man, I thought you better than that. !!

the isuue really becomes one of roofing type, and liabilities.

That is exactly what they were designed for and agree with that totally.
And no, they are not sprinkler heads. ha. ha.

Michael,

Those are either metal or rubber shingles. I usually have to get up close and feel them to be absolutely sure.

I had a home in Truckee, Ca. and we could get substantial snow falls. When we were building our home I wanted to a metal roof but my builder talk me out of it for liability reasons. His feeling was that not only was the sliding snow a people hazard but the falling snow could compromise the side walls or break windows.

Last December at one point they had 13 ft of snow on the ground. The only saving grace was that it was a very dry snow.

Thanks Rick. I thought they may one of those. They look more "plastic" in person. I suspect they are rubber or similar product.
