No metal roof job is complete without snow retention.  SOM offers two excellent choices. Want matching colors?  The Sealtite Snow Trax is a stainless steel powder coated snow guard. Comes with an EPDM gasket. Simple screw down application.  If you prefer a more universal clear look, consider the Yeti Guard from Marco.  The Yeti Guard is manufactured from clear polycarbonate which will not yellow or break. The Yeti Guard can be applied with screws or Sure Bond 190 adhesive.
