Hey guys, I have a large metal storage building (36x64) and had the metal roofing replaced last year. The snow and ice sliding off this past winter was a frightening issue, I didn't really care about the back, but the slope of the roof faces the front door and driveway. Over the winter, the snow would slide off and freeze solid in piles about 6 feet high at times. I had someone come and put up snow guards and he put them very close to the edge. I noticed on other buildings I have seen with snow guards, they are placed a foot or more away from the edge of the roof. Mine were placed very close to the edge and when I was doing some work yesterday near the ceiling, I noticed the screws were just through the roofing and not attached to any structure. Is this how this is supposed to be done? I am concerned the snow could rip the snow guard off and damage my roofing in the process. If it's not correct and the screws should be placed into structure, how do I correct it at this point now that my roofing has holes into it? Thank you in advance for any information/advice!
Snow guards installed incorrectly?

They must be in the framing, and there's a "formula" for the amount. It involves the square footage for sure and possibly the pitch and your snowfall amounts.
What type did he use? Obviously there not the adhesive type but there's a stamped SS type and some type of casting (probably aluminum). I've had the stamped type fold over and also rip out while screwed to the purlins. I didn't use enough of them and only "hit" 2 rows of purlins and don't remember the spacing on each row.

As Jack mentioned, the number can depend on the length of the roof slope, the pitch, your snowfall amounts, and the type of snowguards. I would assume that a 36 foot wide building has over 18 foot slope and probably should have 2 or 3 rows of snowguards. A lot of websites selling them will have a charge showing the recommended number and spacing of snowguards.
I will have to get up on a ladder and get some pics of the snow guard. I was having gutters installed on my garage and had this done at the same time with an Amish crew. They did not itemize all of the supplies and I just trusted them to install what was needed, and to do it correctly. Here is a "google image" of the building. I am in the process of replacing some of the metal panels and getting it painted. I am in NE Ohio in the snow belt, we get a LOT of snow here. The snow guard is installed in this pic, they are small and close to the edge so difficult to see. Thanks again for all the help!
