Working on the roof of my deer blind. The roof is octagon and getting ready to put cap on the seems or try and seal them up. I didn't want to go with roof cap for the size and price. I tried using a price of corner steel and bend it in place but it looks out of place and a lot of fitting. I have seen pictures of octagon roofs with a little piece of trim cap. Anyone know what it's called or where to buy it? Also open to any other ideas at this point. Thank You in advance!
