Stop in for a cup of coffee

Dam house. Just went up on the small flat roof. Stupid idiots put shingles up there at some point and they are leaking. Hell have to call some one to fix it me and roofs don't work well!
What direction do you lay them on a flat roof :wtf::BangHead::BangHead::BangHead: What section do you have flat? I assume it is actually a little bit of slope. Is it enough slope for roll roofing, or should it be a complete sealed membrane?
