I don't think wallpaper would stick to it. But light coats of paint work well. It is not all that sturdy, takes dents pretty easily. Super easy to cut and glue up though. Can nail it up too if you are careful and use those nails with the plastic ring.

they make this great stuff for icedams compensation these days. It is a roll of Shingle material that is peal and stick on the back. It is about 4 feet wide. You put it down as a solid layer before shingling and then the lake formed by the icedam can't seep through. So easy to apply.... but would require reroofing the building. That or just get some of the heating things that go around the gutters and melt the dams.
