WRB for low-slope roof

deerefan | Posted in General Questions on

Hi all,

I would like to ask for suggestions for WRB to use on a low slope roof (1/12). The house is in Zone 2A. My idea is to use Henry 200HT over the roof deck, then Toprock DD 5″ insulation, cover this with Delta Trela and then a metal roof over the top. 

Please send me your thoughts, specifically is there a better option than Henry 200HT? Thank you.

    Hi Deerefan.

    Seem like this would be fine, but check with the metal roofing manufacturer to make sure they like it an will honor their warranty with this assembly.
