What is a good way to fasten three or four sheets of corrugated fibreglass (approx. 2 1/2' x 8') to the underneath of my deck, in order to keep the rain off some garden furniture, tools that I want to store there. I don't particularly plan on putting any sides or end to this "roof" under the deck, but I may.
Answer:
Why not just make it into a temporary, large flat surface so it leans in the direction you want it to. That way, when spring comes, you can take it apart again and stack the components or leave it where it is if you want. The benefit of the large sheet is that you can suspend it from joists with short lengths of rope or some such.
