Hi ya'll, I'm doing a 12'x21' roof over a deck. I have sheeted, and rolled tar paper over roof, and stapled down. I have a flashing tucked up into siding that lays on top of tar paper at top end of roof. What I am wondering is do I put the roofing on top of this flashing with glue under neath, or do I put it under flashing and pump glue into gap? Also what do I do with the tar paper on sides, do I cut the paper flush with roof sides, and do I need drip flashing on sides over face boards? And how does this install? Over tar paper, under roofing? The roofing says to run a 9" wide strip all the way around roof with lots of nails, and then use roofing cement to glue the outside edges down to this, and hide the nails under the two inch overlaps, and glue those to? Any advice would be of great help. Thanks in advance.....
