   The problem that I see is if that is mounted on a "12/2" that it would have a valley on the high side that would be a drainage problem.

   With a 12/2 roof, wouldn't an outlet that is designed for wall outlet be better.

   Pb, thanks
   That is a problem now. The water got under the shingles up hill of the vent. Would a flat roof vent be better?

   Wow did I misread that.

   I was thinking 12" of drop of 2" travel------ oops.

   Yes a flat roof vent cap would be better for a small pitched roof.

   3/12.....12/12......21/12... works great.... sometimes we repaint them to coordinate with the roof

   did we decide if this is a low-slope roof or a high-slope roof?

   as  doodabug  pointed  out  the  #611  is  for  flat  to  low  slope

   you  may  or  may  not  have  to  build  a  curb  to  mount  it  on

   i  think  you  can   download  the  instruction  sheetMike Hussein Smith Rhode Island : Design / Build / Repair / Restore

   i'd  build  a curb  and  bring my flashing  up  to  the  top  , then  use  the  (CM)  flanged  model down  over  the  curbMike Hussein Smith Rhode Island : Design / Build / Repair / Restore
