Slope how low?

Whats the lowest slope to put mod bit on before you go to rubber? 1 in 12? 1/2" in 12?

if you know how to do rubber why use modified at all ?

2 on 12 is pretty much standard

I believe it is 1/2"/12".I would put mod bit on anything with proper drainage.Mod bit doesn’t take ponding well at all.

as long as you have drainage you can use mod bit on any pitch. ponding water on mod bit as said earlier is bad. If you have ponding water the only system i know of that warrants against ponding water is IB(Industries Best) singleply cpa/pvc.Most singleply membranes do not warrant against ponding water.
