do people ever put underlayment on plywood decking and then Perlins on top of that? and is this flashing the same on the top edge slope of a skallion roof?
I used felt paper on decking and purlins over paper.. most of these videos don't use purlins as such under metal roof, but our local code enforcment requires them but not underlayment...? I wanted the felt paper under roof.. plus whilst I finished the rest of the roof,overhangs, soffit and other stuff it kept the water off decking..
I've watched this a couple times, and I can't figure out a reason why you would use a screwdriver to spread the bottom lip? Because you seem to be cutting away any material (1/8" from kickout) that might fit into that lip. I would think that you either don't bother with spreading the lip with a screwdriver, or you only remove material 1/8" from the bottom lip on the joining piece. That way you actually have an interlock of material. I guess it depends on what size the "kickout" is? If the kickout is 1/4", then 1/8" makes sense. If the kickout is 1/2", then only leaving 1/8" is removing too much material.
Well, I cut away two inches of material on the left piece, spread the hem on the other piece apart a bit, then slide the first piece into the second about one inch. One is sorta locked into the other. Does that make sense? There's a three inch overlap but the drip edge slides in about one inch. The video didn't show that but I THINK my way is the correct way.
Awesome Tutorial

The underlayment manufacturer recommends flashing on wood then underlayment to edge of flashing ?
