Hope this will help. I found plastic "velcro" hooks at a store in my area. They are two piece, one sticks to the wall and the other has the hook. You may be able to use them to attach to the flat (front) side of the house along the roof line. I used them for halloween lighting last year and they were still up this year. They seemed to work better when I cleaned the surface with alchol before sticking them on. Good luck.
