creating buildup at point of exit of water idk.....think it was good b4 mesh, most important thing is getting water out and not letting it build up......exit of scupper should be absolute lowest point, sometimes trying to do too much isnt good.......seen this alot where apllication was great but trying to waterproof so much didnt let water to escape which causes issues all in itself get the water out and waterproofing takes care of itself....if water exits properly and quickly there isnt alot of need for excessive steps....just ran into this where they tried so hard to waterproof they made scupper back water up onto the roof and caused a mess because it was too high on not enough slope.....water puddled up and ate through the roof......1/4 in per foot on irregular roofs isnt much with seams build up....
I see your point, and probably something to consider. From our experience in southern california we are pretty sunny. Even if there is 1/8" of sitting water on a regular sunny day it'll evaporate by the afternoon. But I do see your point.
That’s going to leak. There was no reason to nail down the bottom part. You literally are giving the water a path to travel. After applying the primer, a bit of plastic cement on the bottom and properly torching the top would’ve been perfect.
I would not agree. Nails are needed to minimize expansion and contraction in the metal. That is what manufacture recommends for both scuppers and other flashings
@@RoofRepairSpecialist Appreciated, but I’ve installed them both ways. Over the years, the ones without nails gave me no problems. Just saying what works for me. And thanks for the vids
