Ice and Water underneath sheet metaled roof?

[Reynolds]

I am replacing the shingles on my fish house in favor ribbed sheet metal. Do you guys recommend putting down ice and water on the roof edges, the entire roof, or not put any down at all?

I put Ice & Water Shield on the entire roof of my house before attaching my pole barn steel on the roof. I think its a good idea.

I would do it. Have you considered a rubber roof?

When in doubt, cover it up. Its a good rule to follow for many situations in life........
