Flat Roof

Flat Roof
I was told to use SIS rooled roofing on my nearly flat roof. The only rooled roofing I can find at Lowes or Home Depot has only 2 inches of seam area on both edges instead of the 9 inches of seam area both edges. Roofrat told me to use the SIS because I do not want to nail just glue. Anyone know were I might get SIS in the Seattle area?

I understood it had to be nailed at the top edge that is covered by the next roll. Is that correct. I need to look at the neighbors roof. I am sure there are no nails showing.
