Best Low-pitch roofing mat'l?

I'm adding new room to back of my house, 23 X 15 roof area, only 1-1/2 on 12 pitch. Leaning toward rubber-metal too expensive. Anyone have experience? Is adhesive-backed or glue on best? How thick? Where best to buy? Tips on installation? thanks, Krusader

Re: Best Low-pitch roofing mat'l?

There are a few roofing methods for a flat roof, but the best is to ask local roofers to which one works best in your area.

Basically, there are: tar and rock, build up, torch down, rubberized asphalt and others.

My personal choice would be torch down.

Since you don't list a geographic area, talking with local roofers, and the local building authority is best.
