Roofing options

[Rob Tucker]

Jim, I am quite fond of concrete for a lot of reasons. What's with the burlap though? Is it supposed to provide tensile strength? It won't. Since concrete in combination with any other material is a design issue it is not possible to offer a blanket statement on safety... depends on the configuration. Unreinforced concrete,especially for a roof, is a bad idea from a safety point of view.

So again, Why burlap? What does burlap do?? Does it do it well? WIll it last as long as the concrete?
