Not with this trim piece. We do recommend the S5 Snow Bar system also. It attaches to the panel ribs with compression screws so that you don't penetrate the panel.
Yes, a butyl tape sealant works best or tube sealant between the flashing and panel rib.
You'll have to contact your local Home Depot ProDesk to see if they are available to order in your area.
The slanted side faces the eave. The vertical side faces the ridge (high side) of the roof. This side will hold the snow until it can melt. Fasten both sides of the flashing in the high part of the panel rib if available. The more fasteners the better.
There are different length screws for different applications. It depends on what you are trying to attach.
roughly $25 each (2020). You'll need to go tot he Pro Desk to order them.
How much would 9 pieces of the 10'6" metal snow guard 29-gauge galvalume for metal roofing be? How can I order this? What type of screws do I use?

I would not use a 'wood screw' to install these, you'll need a self tapping screw with a rubber neoprene washer to keep rain out of the hole you are drilling. You can buy these screws at most hardware stores (maybe HD or others). They have a neoprene washer that seals the area under the screw so water cannot enter. You will most likely need a small impact driver to install the screws. A standard drill would not be powerful enough.
