We are going to install Snow Blocs on our new barn. It is a gambrell style with a 4/12 on top with the lower at 21/12. Each run is 12' and the length is 38'. How many blocs should I install and at what intervals. We used the standard R-style metal roofing with 9" in between the large ribs and 1.5" between the small ribs. Thanks Bob

The snowguard manufacturers will have recommendations but my suggestion is one guard between each of the larger ribs. There are snowguards made to straddle over the smaller ribs.
